I am tuning my VE and MAF. I was just curious as to what the range for these should be during WOT and highway cruising. I think I have it dialed in but am not sure. At WOT my LT and ST are at +/- 0.0 and at cruising speed LT = 2.5 to 5.0 and ST = 0.0 to -5.0.

Pleases post your LTFT and STFT at WOT and Cruise speed (highway speed).

thanks

ltft and stft are not used at wot. They are only used in closed loop.+/- 4 good for ltft don't worry about the stft.

fuel trims are not active at WOT since you are in open loop. Fuel trims will read with the vehicle in closed loop...you want to be +/- 5% about no more then that

ok. looks like I still got to do some more tuning then as soon as my car is out of the shop.

thanks

So when is the car running in closed loop? Sorry for these questions but I'm cooonnnfffuuussseeeddd....

car will run in closed loop after it reaches operating temp. and generally under cruising conditions. WOT will kick it out of closed loop.
