What would cause the transmission to shift early on the 1-2 wot shift? I have it set to 6000rpm and 40mph. But its shifting at 5700rpm and 37mph. Have the 2-3 shift set at 6100 and 68i belive but...

Seems like the maf was waaay off. Going very lean at light throttle and the difference between the maf and vve caused the p0101 and the maf to fail. Ended up having to add 20-50% more to the maf...
Also, once the p0101 sets it goes back to the vve and drives like normal
Ran I to an issue with the maf tuning. I've reversed what I did to disable the maf. But its sluggish and I'm getting a p0101 when I try to accelerate.
I've got the VVE dialed in pretty good. Finally started working on the MAF tuning. hasn't needed much adjustment. Question on where to have the WOT shift points set to. right now, I have it...
Was looking at the min idle airflow and it looked like it was too high. Avg 10g at idle rpm. Lowered it to 8g and it's idling much better when warmed up.
It happened a few times in this log
i have the maf disabled. It's been well below zero here the past week. won't be able to do any more WOT tuning until around late March or April. I am having an issue where it wants to die after...
Appears that I'm getting some wheel spin in 1st. it's strange because its AWD but 22s on cold pavement probably isn't helping. I lowered the commanded shift rpm and mph and it helped some. would...
Drivability tuning is going well. Got the courage up to do a short wot run. 1st gear was a bit strange with it fluctuating. And it reved higher than what I was trying to command the shift at. ...
trying to tune my cammed 2011 Escalade. Have a AEM Uego wideband. Never notice anything unusual. but when I look at my logs there are a few places where it goes to 655 and its causing my ben maps...
is there a way to better control cold fueling? when its 15 or below outside its very hard to start. takes a few tries. then once the engine starts and rpms settle the afrs will start climb to...
Update. Tuning has been kinda slow. Only get 1-2 logs a day. Usually on my way to/from work. The ve table under 3k rpm is looking good. But was having issues with the transmission. Was looking...
And I have a working wideband now. log showed I need to take an additional 20% out of the idle area on the vve table. got timing alittle better, might need to take an additional 1 or 2* out of the...
New bosch wbo2 came in. Got it swapped in. Went to load a new tune with the vve tables lowered in the idle areas but the battery was dead. Seems I forgot to unplug the v2 from the obd2 port along...
I renabled stft and after about 30 seconds trims went to -25% and the idle started hunting real bad. Guess I'm going to have to wait until the new wb sensor comes in before I can do any more fuel...
New exhaust clamps came in. While their not fully sealed its alot better than before. Most of the leaks are after the ypipe though. The new o2 sensor for bank 2 also came in. Was orginally...
Also thinking my wideband sensor may be bad. With leaving the key on for 30+ seconds then trying to start it. Could have damaged the ceramic inside the sensor.
would adjusting C0805/6 cure the P0068? below 30% throttle the expected change seem kinda low?
I do have some slight leaks on the exhaust slip connections on the y-pipe. Ordered some better clamps that will be here on Saturday
the dtc was set at frame 33000. my efi live wouldnt let me load the pid list you attached. there were a few spots where timing dropped to -15. other than that it was pretty good. need to fix some...
Okay. So went for a drive. Afr was still pegged lean. Then got a reduced engine power. P0068 map/maf-throttle position correlation
awesome. thank you. Guess its time to take it off the blocks lol.
okay. so next step would be to make sure its idling, if its good and when it's at temp do an easy test drive and log. then correct spark and fueling as needed? and for the vve map, does it matter...
It definitely is. Been driving a buddies car while I worked on it and he is about ready to get it back. I did play around with the dvt idle controls some. Took it down to 700rpm. Any lower the...
