Fuel Trim Question Cruising at 70mph my LTFTs read -1.70, but at WOT, the LTFTs go to +4.00.
The STFTs at WOT go to 0. I thought that if my LTFTs most always read negative, that my LTFTs at WOT should go to 0.

Log your ltrims and Fuel Trim Cell (FTC) while driving... take an average of all LTRIM Columns where FTC is 4-19 ... i may have been -1.70 for the FTC youwere in but the average sounds like it's closer to 4.00 ...

Thanks for the reply. What you are saying must be what is happening. At other times the mix must be leaner. I want LTFTs of 0 at WOT. The adjustments done with predator for PE effect WOT only right?
