Why do LTrims need to be 0 or positive if.....?
Why do LTrims need to be 0 or positive if.....? If they are still going to 0 at WOT. My car seems to run better with better throttle response with LTrims around +1.6 to +3.1. They go to 0 at WOT so no fuel is being added in the PE tables. Would I benifit from going 15% rich at base instead of the current 10% rich at base and getting in the range of -2 or -3. Thanks in advance for the info guys!

Re: Why do LTrims need to be 0 or positive if.....? LTFTs are being used at WOT if they are positive.
LTFTs are not being used at WOT if they are negative.
Why John's LTFTs are being set to 0% at WOT when they are 2 to 3% while cruising around, I dont know, But it may be that the last LTFT cell that he leaves to go into WOT mode is 0% or negative.
When I was running around with 20% LTFTs, the LTFTs at WOT were still 20%. However, after calibrating the MAF table and the LTFTs were all less than 0%, ATAP showed that at WOT, my LTFTs were being set to 0%.

Re: Why do LTrims need to be 0 or positive if.....? I've increased my base and now the LTrims cruise in the -'s and WOT always go to 0. Car doesn't seem to run any different so I'll leave it like this. Thanks guys.
