The "Gross Correct" only comes on when the fan kicks on. I did get the INJ DC down to "1.0 ms" with this program and all the other things seem to be in spec. A 12.6 A/F ratio seems to be best with little added fuel by the CPU with the fan on (1.6%) with it going back down to "0" when the fan turns off. The cars idle doesnt change so much when the fan kicks on. I tried going back to the 13.1 AFR but the engine almost dies when the fan kicks on and the idle is erratic. I replaced the rubber gasket for the PCV valve before I let it idle for a while. Now that I got ALL the vacuum leaks fixed I should be good to go for sure on accurate tuning. Of course winter is on its way here so this might be all that I accomplish this year.
