Kpro4 AC problems CTR EP3 Euro
Posted: Wed Aug 05, 2015 5:56 am
Hello. Have noticed that with KPro4, the AC or EPS idle routines do not work as in older Kpro boards. When first engaging AC or turning the steering wheel (especially with the AC on), engine almost stalls. Please find attached calibration and datalog.
***Edit: Some more information. Car was running perfectly well before soldering the Kpro4. So it can't be the idle valve. I have also seen this problem in another Kpro4 equipped PRA but at that time, I did not pay attention as I thought it was the car's problem (or a faulty idle valve or the AC compressor faulty, drawing more power). Engine almost stalls when turning the steering wheel (PSP lights up correctly on the log though).
