Need major tuning help with throttle problems

[Slidewayz247]

I have a dme that runs the car and was done by another tuner. However is having some major part throttle issues. So I bought another dme and ByteTuner to tune it with. Ewd deleted and car starts but is in phase 4 limp and sounds like running off 3 cyl.

not sure if relevant but when the original dme is installed, after the engine is shut off it sounds like the throttle is still under power like humming away.


Please ask away and flog if needed but I'm trying to learn and work my way through this.

Can anyone help even a little please? All the forums are dead so Google searching rough.

I want to know why you diagnosed the DME as the issue rather than an engine or TPS problem. Is you old DME locked?

If you're getting limp mode there should be codes. Use inpa to read them out and post here.

I don't know how I missed the limp mode. Pregnancy brain I guess. Probably a good sign it isn't the TPS either. INPA is great for reading live PIDs with its fancy bars. Feel free to post some videos if PIDs seem whacked out along with your codes.

Did you resolve this?
