- Exhaust Builder Pro Support (Only for this version. Easy Mod support will be added in the next version)

🔧 Dynamic Mesh Tuner + Advanced Body Damage (ECU cars)

Dynamic Mesh Tuner support has now been fully integrated into ECU Tuner. At the same time, Advanced Body Damage has been further refined and stabilized.

➡️ This means ECU-controlled cars can now combine Dynamic Mesh Tuner + Advanced Body Damage for:

More realistic deformation behavior

Better visual feedback under stress and impacts

Improved stability and consistency across sessions

🎥 See the video for a live example of both systems working together.

🛞 New Semi-Slick Tyres + LSD (In-Game ON / OFF)

We’ve added brand-new Semi-Slick tyres, fully custom and physics-driven.

Semislicks:

Custom grip behavior and slip transitions

Improved bite vs. slide balance

More progressive limit behavior

LSD:

Torque- and Slip-Based Mechanical Locking

Load- and Energy-Aware Behavior

Realistic Mechanical Feel (Hysteresis & Chatter)

✅ Semi-slicks + LSD can be enabled or disabled directly in-game

A new status bar icon shows whether they’re active.

🔧 New Tyre Tread & Segment Simulation

Tyre normal-map driven data

Tread data is generated directly from tyre normal map textures using our own tyre data generator.

Per-segment tread simulation

Each tread block has its own grip, temperature, wear and slip behavior.

Natural grip ↔ slip oscillation

Micro grip variations emerge naturally from real tread geometry — no artificial effects.

Asynchronous slip limits

Individual tread blocks reach their limit at different moments, smoothing breakaway.

Progressive grip loss past the limit

Grip fades progressively instead of snapping, improving control at the edge.

Clearer feedback at the limit You can feel when the tyre is biting, floating, or starting to let go mid-corner.

🎮 Advanced Gamepad Force Feedback (NEW)

Tyre texture <-> Gamepad FFB vibrations

Slip split: acceleration vs braking

Different vibration behavior for power-on slip and braking slip.

ABS-aware feedback

Without ABS: smooth right-motor build-up.

With ABS active: transition from right to left motor with speed-based frequency.

Speed-adaptive ABS frequency Low speed = slow pulses, high speed = fast vibration.

LSD lock feedback Subtle right-motor buzz when LSD engages, synced with yaw assistance logic.

Suspension & load-based vibration Vertical load and suspension travel directly affect vibration energy.

🧠 Traction Control – Fixed & Upgraded

Traction Control has been fixed, cleaned up, and extended with new logic layers.

🔹 New TC Features:

Yaw Risk Horizon (≈200 ms) Predicts mid-term yaw instability instead of reacting late.

Adaptive Damping TC influence adapts dynamically to grip, load, and surface conditions.

TC Micro-Oscillation High-frequency micro torque modulation to improve feel near the grip limit.

New values are now saveable in presets: TC micro-oscillation, 200 ms yaw horizon, TC ↔ boost sync and new tyre&lsd&suspension activation

These changes aim for: Smoother intervention Better stability at the limit More mechanical, less “digital” TC behavior

v1.183:

• Engine SFX update (try Aventador, 190 Evo2, R34 GTR, F1 312/67, Audi R8, M3 G80, or AE86 — feedback is welcome)

• Throttle bug below 50% is fixed now

• Completed Traction Control System (now ready for all ECU PRO cars) info is in the attachment

v1.182:

✅ The engine sound is now dynamically affected by the current AFR and ignition timing.

✅ All ECU cars’ engine SFX have been updated.

✅ You can now save all Environment SFX settings per car. All ECU cars are compatible with the Environment app, except for the Supra MK4, Supra MK3, and D&O Civic, as they use a different approach.

✅ TC debug menu now shows switchable average/max values per lap for better TC adjustments

✅ Added speed-based dynamic weight for slip, yaw, G-sensor, and steering angle(So its UI Sensor Weight x Dynamic Weight)

✅ Adjustable initial slip multiplier (100–500%)

✅ Updated wheel slip formula for more accurate results

✅ All TC menu values are now saveable

✅ Civic 1.6 VTI B16A2 Support

✅ Environment SFX is now disabled by default, and the app is completely disabled for non ecu cars; added "Enable NanoRT" (without NanoRT = massive performance drop) button in the app UI

✅ You can now save all Environment SFX settings per car.

✅ Improved traction control precision and flexibility

✅ Initial slip % now dynamically adjusts based on RPM, TPS, G-force, and vehicle speed ✅ Implemented 50ms prediction for slip angle and yaw response

✅ All VTEC menu values are now saveable -Advanced Traction Control (Yaw + G-Sensor) Two new sensor modules added to traction control, each with its own on/off switch and adjustable parameters.

🆕 Yaw Sensor Compares target yaw (from steering + speed) with actual yaw (from velocity). Detects understeer / oversteer and adjusts TC response. UI: K_YAW_OVER – oversteer sensitivity K_YAW_UNDER – understeer sensitivity YAW_CURVE – shaping of yaw response Effect on TC (0=max, 9=min) – influence strength

🆕 G-Sensor Reads lateral and longitudinal G. Reduces TC when car is already loaded in cornering/accel. UI: G_LAT_MAX – max lateral G G_LONG_MAX – max longitudinal G K_G_LAT – lateral sensitivity K_G_LONG – longitudinal sensitivity G_CURVE – shaping of G response Effect on TC (0=max, 9=min) – influence strength

v1.181:

-Introducing the new Drive-By-Wire (DBW) feature

-Smooth power adjustment based on maximum throttle opening and RPM

-1x8 DBW RPM-based table to customize throttle opening at different RPMs

-Ability to set max throttle opening for better grip if your engine is overpowered

-Real-time display of PP (Pedal Position) – compare it with TPS

• DBW intensity by temperature limits

  • Added IAT (Intake Air Temp), CLT (Coolant Temp) and EGT (Exhaust Gas Temp) safety controls.

  • For each sensor, you can define a threshold temperature.

  • If the temperature rises above this value, DBW intensity is scaled down (40–100%).

  • Example:

    • IAT threshold = 50 °C, IAT intensity = 70% → once IAT > 50 °C, throttle opening will be limited to 70% of the current DBW value.

• Stackable scaling logic

  • Final DBW opening is calculated dynamically from all active factors:

    • RPM-based intensity

    • Gear-based intensity

    • IAT / CLT / EGT intensity

• All DBW tables and intensity values (gear, RPM, IAT/CLT/EGT) are now saveable into presets.

• Gear-based DBW control

  • You can now set maximum throttle opening (DBW limit) separately for:

    • Reverse (-1)

    • Neutral (0)

    • Forward gears (1–9)

  • Each gear can be assigned a gear intensity value (40–100%).

  • Example: Limit Reverse to 60%, Neutral to 50%, Gear 1 to 70%, etc.

• DBW by gear intensity combined with RPM intensity

  • Gear intensity values are not absolute. They are scaled by the existing RPM-based DBW intensity map.

  • This means final throttle opening = RPM intensity × Gear intensity.

  • Example:

    • At 5000 rpm, if RPM intensity = 80% and gear intensity = 70%, final DBW = 56%.

• Steering Wheel Sensor for Traction Control Features:

  -Dynamic TC Adjustment Based on Steering Angle Reduces traction control intervention depending on how much the steering wheel is turned.

  Sharp corners → TC allows more slip for smoother apexes.

  Straight sections → TC operates at full strength for maximum stability.

  -Smooth Transitions with Low-Pass Filtering

  -Prevents sudden TC cuts when the wheel moves slightly.

  -Ensures natural, fluid behavior in minor corrections and apex navigation.

  -Adaptive Response to Quick Steering Movements

  -Derivative of steering angle detects rapid corrections or evasive maneuvers.

  -TC is temporarily relaxed during sudden steering changes to prevent harsh performance cuts.

  -Customizable Parameters for Player Tuning

  Sensitivity: Influence of steering angle on TC intensity.

  Curve Sharpness: Curve exponent shaping how TC reacts to large wheel angles.

  Min TC at full lock: Minimum TC strength, even at maximum wheel lock.

  TC reduction on fast steering input : Strength of TC reduction during fast steering inputs.

  Improved Apex Exits Allows controlled slip when accelerating out of corners. Reduces abrupt TC interventions, making acceleration smoother and more predictable. Seamless Integration with Existing TC Logic Works alongside wheel-speed-based slip detection.

  Modulates ignition retard, boost, and fuel cut dynamically.

  -Function updates every loop cycle (50 ms by default) for responsive, yet smooth TC behavior.

v1.180:

• VTEC:
  ✅ Set activation based on:
   • Throttle Position (TPS)
   • RPM
   • Coolant Temperature

• Fuel Cut Bug:
   • The fuel cut bug (introduced in v1.179) has been fixed on all ecu_pro cars.

• 🧠 Engine Type Differentiation
  Engines are now categorized based on valvetrain design:
  → DOHC (Dual Overhead Cam)
  → SOHC (Single Overhead Cam)
  This allows for more accurate camshaft behavior simulation and tuning logic.

• 💾 Cam Angle Presets
  You can now save and load camshaft angle presets, making it easier to compare setups or restore preferred configurations.

How cam timing affects torque and horsepower across the RPM range:

Advancing cams (+ degrees) shifts power to higher RPMs with more top-end torque

Retarding cams (− degrees) improves low and mid-range torque at the cost of peak power

Turbo spool and boost threshold tuning:

Advancing both intake and exhaust cams (+ overlap) lowers turbo spool threshold RPM and reduces turbo lag

Retarding cams raises the threshold RPM, increasing turbo lag but potentially improving drivability at low RPM

Exhaust Gas Temperature (EGT) management:

More cam overlap (+10/+10) increases EGT by up to 80°C, indicating hotter combustion and potential knock risk

Retarding cams reduces EGT, improving engine safety margins

How to balance intake vs exhaust cam adjustments:

Intake cam timing impacts cylinder filling and air charge timing

Exhaust cam timing controls scavenging and turbo spool dynamics

Practical tuning tips:

For quicker turbo spool and earlier boost, advance both intake and exhaust cams towards +10° For maximum high-RPM power on naturally aspirated engines, optimize cam timing for advanced intake and moderate exhaust timing

For street or daily driving, moderate cam timing (near 0°) balances drivability and performance

v1.179:

-AFR changes based on the difference between fuel pressure and manifold absolute pressure (MAP):

Ideal condition: Differential pressure greater than or equal to 3 bar.

When the differential pressure approaches zero, fuel flow to the engine stops, resulting in an extremely lean AFR.

-New autotune feature for Ecu Tuner Tunes injector open time correction/AFR map

Set map range, update timer and desired AFR value

Enable autotune, drive, and table adjusts automatically

Inspired by my real car ECU project from 5 years ago(check attached video) ttps://youtu.be/mLskciEnKik

v1.178:

-Dynamic mesh tuner v1.03 for ecu_pro cars

-Environment SFX app- Dynamically checking the environment around the car and adjusting the engine/exhaust sound position, effects, and volume accordingly. A new wind SFX was added for objects close to the car. Adjustable effect intensity, detection interval, wide SFX, wind env volume.

-New Fuel Cut Configuration

– Set up fuel cut when coasting in the Fuel Cut menu.

Three Adjustable Parameters(saveable into presets):

RPM threshold – Fuel cut activates if RPM is above a specific value.

Throttle Position Sensor – Fuel cut activates if the throttle is below a set value.

MAP Sensor – Fuel cut activates if manifold pressure is below a desired value.

Fuel Cut Behavior: When fuel is cut, AFR value is 22.4. If fuel cut is disabled while coasting, the AFR table is used instead.

Effects on Engine Braking & Throttle Response: Disabling fuel cut reduces engine braking because fuel continues to burn in the engine. If AFR is too rich, fuel is not cut and burns in the exhaust instead. AFR adjustments affect engine braking and how smoothly throttle responds when resuming acceleration after coasting.

v1.177:

✅ Collision-Based Damage(you can combine with advanced body damage) – The car deforms exactly where the impact happens.

✅ Realistic Bending – The hood lifts and crumples like in real life.

-Mclaren F1 GTR

v1.09:

-new car Nissan GTR

-You can now adjust your fuel pressure with adjustable fuel pressure regulator from 2-4bar(30-60psi)

-base fuel pressure is about 2,3bar(33psi), so you can gain 34% fuel on 4bar fuel pressure

-with FPR you can squeeze out more from injectors

-Injectors parameters were changed for all cars

-other small changes

v1.08:

-new car audi R8 V10plus (FREE&PRO)

-pre-throttle body situated IAT sensor simulation (based on ambient temperature and Boost, RPM, Vehicle speed and Intercooler)

-Charge temperature simulation(is changing based on IAT, CLT)

-Charge temp affects EGT (High IAT = Faster raising EGT, Lower IAT = Slower raising EGT) AFR (High IAT = Richer AFR, Low IAT= Leaner AFR) Knocks(High IAT = weak knock resistance, Lower IAT = higher knock resistance)

-there are 2 new IAT maps 1. IAT fuel correction map(from-10% to +10%) 2. Charge temp (It defines content of the cylinder after closing all valves) based on Injectors Duty cycle (LOAD) 0% = CLT temp 100% = IAT temp Basically, if the velocity of air being sucked into the engine is low, the charge temperature will be more relevant to the CLT (Coolant Temperature). However, with higher RPM and boost (LOAD), it becomes more relevant to the intake air temperature (IAT) .

-10% more power was added (100C IAT = 0% extra hp, 0C IAT= 10% extra hp)

-added new Intercooler feature You can choose between stock(N/A for naturally aspirated cars) and Stage1. N/A cars like AE86, E30 M3 and MX-5 MIATA can use Turbo without Intercooler, spool will be faster in lower rpm, but IAT will rise significantly

-Bigger intercooler = slower turbo spool, more turbolag but lower IAT=more hp -changing stock Intercoolers and Exhaust to stage 1

-now its visually just for fun, later You will be able to change parts only when car speed will be 0kmh

-00s and later cars will use different diagnostic in some next version

v1.07:

-New car Toyota AE86 (FREE&PRO)

-added new HELP feature (FREE&PRO)

-updated sfx (PRO only)

-better optimized (PRO only)

-minor changes (FREE&PRO)

v1.06:

-Bmw M3 E30

EGT simulation

-EGT is changing based on Injectors DC, Boost, Injectors size, AFR and Ignition timing

-added EGT control menu You can set fuel enrichment (0-20%) and EGT temperature when it will start interfere(750-900C) with 50C hysteresis

-New EGT warning light in status bar(light up at set EGT temp in EGT control menu)

-New ECU error code 41 for EGT over 950C(fuel cut will occur)

-Exhaust muffler will glow based on exhaust temperature

v1.05:

-Mazda Miata

-Presets

-Exhaust boost valves

-Diagnostic port

-Map switch/Overboost button

-small fixes

v1.04:

-Audi Quattro Sport incorrect boost building was corrected based on real dyno graph

-You can reach ∼1bar boost with stock injectors, stock turbo is capable for ∼2bar

Coolant system simulation
-engine coolant circuit simulation with 80degree Celsius thermostat(CLT)
-radiator coolant circuit simulation
-2 electric fans control separately
(start temperature from 85° -120° )
-overheating start over 110°
-coolant capacity is 10l, will be reduced progresively if engine is overheating(low coolant level warning light was added-yellow if coolant capacity is below 7l and red if its below 4l)
-refill button can be activated only if yellow or red "low coolant capacity" light is on.
-if your coolant capacity is low your fans will be not efficient enough to cool down engine
-there is engine cut on 150° temp
-to activate refill button, speed need to be 0km/h and it take 1liter/sec to refill circuit
-new status bar with ecu light, fan1, fan2 lights and low coolant level warning light
-coolant temperature gauge on dashboard works with ecu tuner now
-interior overheating light ligt up from 110°
-fan1 & fan2 sound , boiling water sound
-water fumes from hood are progresively visible from 110° , also reacts to active fans

v1.03:

-Launch control, Antilag and Rolling Antilag

-new animated banner

-from now all cars will be Base(free)/Pro(patreon) versions. Pro versions will include launch control, antilag, rolling antilag, 2 different compression ratio, 3 different turbos, tunable up to 3bar, 3 different injectors, Data logger, exhaust gas temperature , intake air temperature, coolant temperature and more later

-Nissan Skyline R34 incorrect boost building was corrected based on real dyno graph(with 2 turbos)

-You can reach 1,25bar boost with stock twins and 1,1bar on redline with stock injectors(444cc)

v1.02:

-Toyota Supra mk4 incorrect boost building was corrected based on real dyno graph(with 2 sequential turbos)

-Rolling antilag, Antilag and Launch Control simulation only available in PRO version(on Patreon) soon

-Rolling antilag, Antilag and Launch Control boost building and building time based on AFR enrichment and ignition timing retard( 35ATDC = 2bar boost, 5ATDC = no boost )

-9.5AFR= max boost, you are loosing MAX boost above 9,5AFR and under 9,5AFR boost starts to oscillate

-added sounds for antilag(based on RPM , boost)

v1.01:

-Injectors Duty Cycle simulation(more than 90% = ecu error code 12), also it is affected by Injector correction map

-You can choose stock or bigger injectors(650cc), you need to tune bigger injectors, if you want more boost than 1,4bar(which is max for stock inj if you tune it properly). Bigger injectors on low DC = unstable AFR

-there is no more need to turn off UCR and vJoy if you want to play with no ECU cars

v1.0:

-realtime RPM limiter

-realtime Boost limiter (up to 2bar, base boost is 1,2bar)

-realistic wastegate 7psi/15psi springs with different boost build times based on RPM, TPS, Gears

-Manual boost controller (0,5bar can be adjusted up to 0,9bar, 1bar spring can be adjusted up to 1,6bar )

-AFR info, MAP info

-ECU light(rev limiter, boost cut)

-PWM boost solenoid table (can be adjusted up to 2Bar)

-Injectors opening time correction table (0 is no correction, 50 is +50% injectors opening time, -50 is -50% opening time)

-Under 10AFR/over 17AFR engine will missfire progressively, 12.5-13AFR is full power(+10% over standard F40 on base boost)

-Knock sensors simulation (Fuel cut is activated in boost when AFR and Boost reach specific value, for example over 12.5AFR + 1bar boost = KNOCK )

-Ecu error codes (blinking, reading, clearing) and ecu codes list

-Ignition timing base map simulation

-Ignition timing affect also boost build time and AFR Retard timing - faster spool up and richer AFR Advance timing - slower spool up and leaner AFR -knock sensors simulation for ignition timing

-Base maps(afr and timing) are for stock boost only ∼1,15bar/17psi . If You want bigger boost, You need to tune it! -Ignition correction map (max 20deg advance or 20deg retard timing, every 1deg advance gain 2% of power, every 1deg retard loss 2% of power
