Summary of change:
'''BMW 3 series E21 Turbo''' '''2007.07.09''' Car is started yesterday with firmware 1.1.18, no tuning yet. Questions: * With 6+2 IGN hw config ordered, which outputs are power-outputs? * In 1.1.18 firmware does iac_speed variable changed? What unit can be seen in megatune? Lower value seems to make faster freq. * Stock M44(?) IAC valve don't seem to follow positions at all, any experience with it? * What can cause ignition advance over the table? I see 19 degrees when 14 is in the ign table (around idle). ---- '''OLD STUFF''' '''Project goals''' - 300+ peak BHP - reasonable daily driver '''General hardware''' - M10B20 (2000ccm) 4cyl 8v engine - T3/T4 hybrid turbo, external wastegate - big FMIC '''ECU-related hardware''' - custom 60-2 trigger wheel setup with VR sensor, missing tooth is 120 degrees BTDC (copied from M40 engine, the source of the wheel) - 72lbs low imp injectors - later motronic IAC valve instead of old mechanical one - big throttle body with TPS potmeter.
