Thanks a bunch, Brett.
I have applied the baseline table. I have also disabled the TPS adjustment and set the TPS properly. (Zero'd .63v closed, 5v WOT). It actually used to be set like that but the bolts securing it may have been a bit loose, allowing it to shift.)
It is difficult to get a location here where I can go WOT from 2500 to 7500 in 3rd gear as the interstate is real busy (especially with troopers), but I will seek out a place.
My goals are to continue to use this as a daily (I ride share with the Wife, so this gets daily treatment when we have to drive separate for an appt.). I have a few feelers out for a 399 MAF and connector/cable. Maybe the Ft. Wayne guys will have one for me. IF not, then I will be getting what I need for SD.
Quoting GSTwithPSI:
That second gear pull doesn't give me enough good data to work with. I could make adjustments based on that pull, but I'm positive they would be off. I need a 3rd gear pull from around 2,500rpm to whatever redline for your car is. Based on that, I will be able to make accurate adjustments to the MAFcomp table assuming everything mechanical is sound.
Your DA AFR table is set way too rich. On 93 octane, I shoot for 11.0:1 as a baseline for my pump gas tunes. I'd consider leaning out your table. I have a decent baseline table here:
click . You can download that and load it into ECMlink if you want.
Your TPS is still jacked up in the "newlog" file. The best way to ensure your TPS is set correctly is to uncheck the "Enable TPS adjustments" box and not allow ECMlink to correct it for you. I've seen dicked up TPS sensors cause a bunch of strange issues, so I never recommend relying on ECMlink to correct for a incorrectly adjusted TPS.
Going SD or an Evo MAF really just depend on your goals for the car. If this is a build that will stay relatively tame, and you plan to drive it a lot, I'd say swap to the Evo MAF. If more mods and power are planned as future goals, I think SD would be the better choice. Both are exponentially easier to tune, and more reliable than the GM MAFs, IMO. I know people who claim they are great, but like I said, I've literally never seen or tuned are car where it performed well all around.
