Conversation Between Lead Head and 1Butcher

The calibration is stored on the computer. If you have the correct strategy file, you should able to read the stock calibration from your computer. In the worst case scenario you can't find support for your AHACA computer, you can just get an AHACB computer and start from there.

Thanks for your help. I have tried to research this issue for some time, but I now have the time to spend on this ECU issue. So you say my OIL2 is the calibration code and the language of the ECU understand is AHACA. If I purchase a QH/Tweecer then I should be able to talk to the ECU because they understand AHACA, but it would not show the original calibration since it does not know OIL2. Am I close to understanding this or am I way off base. Any help would be appreciated. The last thing I want to do is to purchase something that will not help. Thanks again, Mark gearllc@hotmail.com
