This is probably painfully obvious but I'll still ask.
Is STFT equal to Lambda?
I ask because I've been adjusting the MTF trying to get everything to hit near 1. Been logging and adjusting for a few weeks now off and on and at high MAF counts I just couldn't get the STFT to go to 1. Was always something like 0.725, 0.850, ...
Tonight I turned my brain back on, I think hard to tell ya'know, and I looked at my fuel source, 5, and it hit me. I open the base fuel table and I'm looking at a target Lambda of 0.85. I flip back to my STFT log at high MAF counts and sure enough it's pretty damn close to 0.85 and
the STFT only goes to that when I enter the base fuel table. So I think I'm finally understanding this crap and I got it working?
Why this didn't dawn on my before is beyond me. Seems obvious now
The only thing that's still odd, maybe, is that when it goes to the base fuel table, 5, my load goes above 1. Runs great though. But it's done this the whole time so it seems like that's how it's supposed to be. I know in one of the other threads you guy's had said my injector calibration or something else must of been off, but far as everything up to the switch to 5 is concerned it can't be; it's nearly perfect. Load at warm idle is a tic under 0.2, steady speed cruise in 5th is about 0.32 load.
Possibly the 'percent load switch' has something to do with it? I have mine set to 1.
Anyways, I have the 42# injectors working pretty damn good I think. Now I have to play with spark more and get that sorted out. I was running the SCT 'race fuel' spark map with no knock at all. But now that the fueling is closer to what it should be, or what I'm commanding, the KS is adding a bit and pulling a bit here and there. Easy fixes.
