Hi.

I has a boost problem in my friend car.Boost oscilating and n75 work very veird.
Can anyone tell me what I can check or log?
After unplug n75 I has 0,4 bar boost so WG set properly.
N75 new OEM and DV new OEM too.

Ok, so I must log PID var.
Car mechanical is stock only has a program changes. On dyno has 267 HP. That's all that I know. From maps that are changed is LDRXN and KFZW and has more maps that I didn't remember now ( I only look into the program). From what I remember KFVPDKLD map all is set to 1,25.
What did this map do? Is it only for diagnostic or for something more?
Pid which I must log :
ldptv
lditv_w
ldrdtv
or something more?

Ok log attached.

So what should look IMX? PiD maps are stock. So why is not good?

I don't want to tune. Car has issue and I want know what to check to know its a regulate problems or something with mehanical parts start doing bad. I didn't tune that file because i know is better to start from a scratch. Car was tuned and stop drive properly.

But i tell my friends its mechanical problem with wg but he want bo be sure before he take out turbo. And with that i can learn something with interpretate logs that why I'm saking how IMX should look.
