Hello,
I have had hp tuners for a while but havent messed with it much.
I have a friend that just purchased a previously swapped cadillac
The thing is running super rich on bank two . The Bank Two LT is pinned at 25%
We tried swapping the o2 sensors from one side to the other and the condition doesn't change
The car is also throwing a p1154
The other problem is that the pro tuner has locked the tune I believe . I'm recieving the x7F negative response error when I try to read the tune.
The harness appears to be manufactured by the same company as the tuner
As far as I'm aware this is a GENIII 5.3 that is stock(Running an ls1 intake) with a stock 4L60E.
Any ideas on my next steps or anything I could try?
I have attached the datlog
Thanks for all of your help in advance! ,
Chris
