    if you are having issues with stalling and such, it might be that your stock primary 02 sensor isnt keeping hot enough.

    numerous turbo j bodies have swapped to a universal 4 wire heated 02 sensor and have been able to have the car respond like normal.

    I had this stalling issue but after adding 25% VE in the Idle VE table, it was ok.

    I was wondering how to reset fuel trims on this VCM. Do they reset at every flash? The option in the scanner is disabled for me.

    I made a 10 hours trip with it and was really surprise by the fuel economy. I think that if my fuel economy was so good, my primary o2 sensor is probably working ok or else it would cost me more gas... Is that right?
