EDIT: Forgot logs, now attached :)

So, I ran 3 MAF g/s logs today up to 100 g/s, and I did one at idle (all attached to excel sheet in tabs). My FT's look pretty good as they are, but I'm going to calibrate it anyways.

I knew something funky was going on around idle (just off idle). My fuel trims will go from 0.0 to +7 when I'm at very light throttle. It must be happening within the first breakpoint, which I don't understand. Unless my current maf curve has a giant dip for a few voltage points, which is highly unlikely, then I don't understand what's going on here. My fuel trims from off idle up to about 2.6 volts. Where the hell is this +7 popping up from? How do I get rid of it?

Looking at the g/s tests, and looking at my STFT's didn't shed any light on things. The first log shows quite a few positive STFT's, but the other logs show some negative, and bouncing around (as they should) but the LTFT's are steady at +3.74 (as they should be.... I had like 150 miles on this map).

Second, my idle is off... it reads -2.5 from 1.1-1.2 volts. I've never had to calibrate the maf at idle... should I multiply a larger range of volts by .975, or just right at 1.1-1.2?

FINALLY.... I forgot to increase my idle on my current map, so I'm only idling at around 700 rpms, and not 950. I'm going to bump it back up after I get some input on how to calibrate the above business. However, should I leave the idle alone, and just calibrate the rest of the breakpoints to see what it does at 950rpm idle? I'm assuming 950rpms would be a tad higher in voltage over 700rpms.

TIA

PS. I don't mind calibrating the maf again, but I'd like to get it pretty solid and increase my idle so I can start tuning my ebcs.

Doogie, quit screwing around. You know that when you change the idle speed, the MAF CAL will be off just a little bit at idle because you are running into MAF voltages that were previously below the idle threshold. I can't see your MAF table, but if you reset the idle to the value when you did the MAF cal, the FT will likely settle down.

Also when you step on the throttle, the ECU adds fuel enrichment and you will see the STFT jump to + in response. It is transitory and should not reflect in the LTFT though.

You likely flashed the stock map back to the car..?

lol. I don't know wtf map I'm on, but I'm pretty damn sure it's a modified Stage 2 +fmic map. I doubt my FT's would be within +/-4 from the stock map and maf table values. Yeah, I was thinking of leaving the idle part alone, and just calibrating the rest, and bumping my idle back up, and see how she responds. I gotta get on that wgdc stuff... I'm only hitting 15-17 PSI... wtf?! That's another reason why I'm pretty damn sure it's the +fmic map w/ my previous wgdc tweaks (reduced for boost based map, but way too low for load based... for me anyways).

It's been so long since I've used the AP, I don't even know what map I'm running! :/ LOL, how sad. It's really good to be back though :D.

What's a "Pro-rune"? Sounds like a really ask-kicking Prune that will take out your entire large intestine..... LOL

LMAO!!! Good eye, hahaha. Screw the pro-tune... I'm getting a rune, lol.
