I have suggestion for little change regarding IAC follows tps when not idle. Now IAC position jumps to reference table value when not idle. It cause some transitional jerk if real IAC position is some % or steps less than reference.
There can be two solutions: *follow from current position *stay at current position Choosing to disable did not help much. In addition if turbo used and intake end of valve is not connected post turbo, there is no way to close 2-wire BOSCH PWM valve. It opens in "limp home" mode and cause boost leak. Suggestion: *move to definite position. Slow if little throttle, fast if more. Just try 1.1.41 on real car: Jaguar with 4.2 6cyl inline. Target is smooth drivebility and nothing else. My basic reason to try new code was iacref_matslope - feature what allows rise up PWM valve reference position in traffic jams, where IAT goes rocket high. I try two extremely different circumstances: simulate traffic jam (IAT around 60degC) and idle after extended highway driving(IAT 20degC). Looks like maximal 3%PWM slope @70degC still not enough. I think maximal must be around 10%DC - it must be more than enough. I use BOSCH valve from OPEL. Idle 700Rpm. Also baffle for smooth driving is my previously described issue with IAC follows tps when not idle from ref position whitch is allways little higher tahn real idle DC. ---- |
