long term fuel trim (LTFT)
Sounds pretty muche exactly like it means. O2 sensor senses your are not 14.7 AFR and makes adjustments to the STFT. If the adjustments continue your LTFT gets adjusted.
We are tweaking your maf scaling and smoothing because your car is inconsistent with the fuel trims. Of course all i have to work with is o2 sensor which isn't that great.

oh man lol Road spike is going to kill me lol, I know you have been working hard on my tune but I found the problem!!! When I teed my vacumn lines awhile back I reused the old ones and it was leaking air. So I used my super cool handy dandy boost leak tester and found my leak in the tee lines, so everytime I boosted it couldnt get the fuel in the engine quick enough to keep up with the demand of air to fuel. the only reason I was running rich was probably because I was still in the vacumn area and not boost.
Ok im about to log a start up and a few revs, im kinda nervous about driving around the block real quick because I don't know how this tune will react since I fixed the leaks

Drop the injector scaling back down to 410 or so.

I can't use that to tune with..
It shows no airflow, no load, not even o2 feedback and its only 20 seconds long
Edit:
Going to send you a best guess rom anyways. We know your AFR is sitting in the 10's so i'm just going to lower the latency to try and get that back to normal and basically smooth out maf scaling to stop what we were fixing with leaks. I'll lower the timing in the area it knocked to try and stop the light from flashing and also remove the tephra point which calculates airflow.

ok I dont know if anyone remembers but I had car troubles to where I couldnt start my car because it just cuts off before I can crank it. Well I found out that I had some corrosion built up on it... so I got some cleaner stuff and a brush and took care of that pest!!!
quick question did any of you guys change the following to keep your idle down and still use your ac? I almost killed my girlfriend because I couldnt use it and I had all the windows down lol.
on the idle tab it says
desired idle rpm
desired rpm with ac on off etc....
did anyone change these back to the stock settings to keep your car from overheating and have the ability to use ac, or should I leave them alone with the tephra settings?
