Pete_89t2 Posted May 30, 2022 Report Share Posted May 30, 2022 I'm trying to understand an issue I'm having with my tune where I'm seeing acceleration enrichment being triggered sometimes when it shouldn't be. I'm running an E-throttle, and my acceleration enrichment setup has "Accel Mode" and "Accel Load axis" both set to TPS. I recently got my A/C system functional, and have been trying to tune my idle controls to deal with the A/C load. While doing that, I've had situations where the engine is nearly stalling, but the closed loop idle control catches it after a bit of hunting/oscillation. In my logs I've noted that sometimes when it behaves like this, my accel enrichment gets triggered, even when my accel pedal position is sitting still at 0%AP(main) / 0%AP(sub). The TP(main)/TP(sub) values bounce a bit between 0~8% or so until the idle settles down and stabilizes. So the question is should I consider changing my Accel Mode and/or Accel Load axis settings to MAP instead? I'm also running closed loop lambda control at idle, so the unwanted accel enrichment tends to bugger that up. Quote Link to comment Share on other sites More sharing options...
