Re: air fuel ratios???
useless your not still trying to crack the eec-V ?
Its been around a while and I don't think anyone has been able to do it!
You can bypass it thorough the OBD port and use interceptors but reflash it with your own custom program sounds like too much work. If you do it you would be crazy to then give it away in kit form for a few $
Wait for the chip challenge stuff from Casper if he ever gets it finished and see what the chiptorque and unichip did in a fairly well controlled back to back test.
The results whatever they are will be hard to ignore.
By the way I am amazed yours runs so lean even with the DEV4 as mine is so rich its not funny. I checked my plugs again today Autolite 985 (Dev spark plugs) and they are black and sooty!!! SO is the tailpipe, tailgate, garage door where I park etc.
I got to get this Unichip soon!
