Hi All, I am trying to tune a new application for myself. It is a TBI 350, I am using a 7747 ECM and $42 mask code. The car runs fairly well and shows no codes.
Using my Antique Auto x Ray I can connect and monitor the car. However when trying to connect using Tunerpro RT it will only work before I start the car.
I can get it to connect with the key in the on position and I can look at the the items list and see things such as the TPS changing when I depress the pedal, but as soon as I fire it up it begins connecting and disconnecting every few seconds. I have tried some of the normal fixes without having any luck. Suggestions?
Thanks
Roy
