Let's get technical: Tuning the ECU for mpg

[ashiga]

I just raised the closed loop threshold (throttle position x rpm) for all values on my D16Z6 P28 ECU with chrome, I'm hoping to get better mileage as I'm a hard driver but I usually keep my foot below WOT. I changed the threshold values to about 80%. That's an idea I just had, so I'll tell you if I get bad mileage which I think is unlikely to occur as when I had a wideband, the stock basemap produced 12.5 AFR when in open loop.
