Default Throttle problem MHD pump flash + misfires - 03-08-2017, 01:34 PM

Hello All,

I had have a problems with trims and misfires (cyl1), so I decided to do MHD flash. I flashed standard MHD pump flash. Problem with thrims during 3rd FOT maxed out is solved now.
But I have a problem with throttle. Without MHD (JB4 only), the throttle coresponds with the pedal (more or less), but after MHD, I have sometimes problem, that the throttle is not maxed out and I get the full boost later than before (3600- without MHD, now 5000 rpm)

Other thing is, that I still get engine light (misfires) + AFR 20(in the log) - I do not know, if it is a cause or the result of the misfires, the engine after the light doesnt run well, after errors reset everything is OK. I think it could be caused by the lambdas or what do you think. AFR20 could destroy the engine I think

Thank for your help
