Long story short.
I had the car tuned on a diablo by a tuner. I had knock issues because winter blend fuel.
I then did a pass at the track and the fuel system was maxed out.
So I decided to change tuners and go with a flex fuel tune using hp tuners.
Since I had a pcm unlock by diablo i needed it done by HP Tuners something I figured was pretty standard with them.
After 3 days of not receiving the pcm back I had my current tuner reach out to HP tuners o see where it was at
HP tuners reply was just sitting here it was already modified. Was it returned to stock?
My tuner replied and said yes it is back to stock it's an 18 so it needs to be unlocked by hp tuners
So the next day i got that in. Followed the instructions on the sheet and sent my tuner the stock file.
Today he sends me a startup file. I wasn't able to get to it until right before 5 o clock.
The car idled real bad and I noticed it codes come up
So I pulled codes and they are listed below
Let me make sure everyone knows THIS IS NOT THE TUNERS FAULT!
The car is not recognizing a whole bunch of stuff.
I clear the codes they come right back
Has anyone had this issue going from diablo to HP?
Current issue
