Re: Im going CRAZY, WOT tuning is being a bastard! Running out offuel

Pablo,
you didn't say what your O2 readings are.  When chip tuning, always
take notes, and keep copies of each bin as you go, so you can "go back".
If you think the ECM's learning curve is fighting you, kill the power
to the ECM and make another test run.. You didn't mention what you 
are using to gather data, but I would think the integrator numbers should
help you tun the fuel...
