OE Pro Tune V3.1.3

What's new since 3.1.2

  • Engine physics: stock cars now make their real stock power. Timing has a real flat peak, knock control is closed-loop, and every engine has its own knock limit. Runtime Values has a new Power factor breakdown.

  • Fuels and mixture: every fuel has its own boost ceiling, cooling and best mixture.

  • Fuel hardware: injectors and pumps can run out now. New OE Fuel System parts can feed 2,000-3,000 hp builds.

  • OE Turbo System: 11 turbos on real compressor maps, plus twin turbos and a CO2 wastegate dome.

  • Heat and protection: real exhaust heat and damage, a real ECU style protection mode, and a smarter Tune Doctor.

    Sound, gauges and connection: louder pops, 2-step and anti-lag. The AEM gauges were redone and the connection status is clearer.

    Hard Cut and rev limiter: a new Hard Cut page, and a rev limiter for engines that don't have one.

  • Shifting and idle: a shifter cut with a downshift blip, and a rebuilt rotational idle.
