Well I am having an @ss load of with this TPI conversion. I made my cable (two transistor) and got Cm ECM845 to link after a few reboots and attempts. After I link up and look at the live data the data is way off. It says car is running when it isnt, RPMs not correct,TPS position does not change as throttle is increased, and the list goes on. I am beginning to wonder if I have a bad ECM. If anyone else had a similar problem and confirmed cause please let me know. Suggestions are welcome and needed!!!
