I'm looking for some help in finding a program that will allow me to make changes to the air fuel ratio and ignition timing on my 94 v6. The car does have obd2 and I can read codes from it as well as get engine data. I have a obd2 to USB cable for my laptop so I'm looking for something that would use that same cord but allow me to make changes. Whether it be a reflash of the whole ecu or just tweaking it.
Any help is much appreciated
