I was also fighting this. Problem is I already took the wideband out now to keep refining. Ive found that it is way too much fuel. Engine is already warm, shouldn't need cold start amount of fuel....

You need to tune the VE and the maf has to be disabled during VE tuning. I can't believe that thing even ran with the MAF like it was lol.
One thing at time. Start with keeping the MAF disabled...
I have to ask why delete the PCV and EVAP? Figure out your injector part number and reference Blindsquirrels spreadsheet. I think his is for 58PSI, but the fuel rate should be same across the table...
Oil consumption? Is there a crack?
Uff. Double check your injector data like the others said. You have a completely jacked VE table. 1 Degree of spark along with in and out of fueling is going to give you grief.
Once you are more...
What is all done to the engine or transmission? 480hp on a chassis dyno? Your MAF is definitely not right. I can't remember if that affects the trans shift pressure when the maf is failed. Either way...
Well I did play with the adder modifier table. So far seems to work pretty well. Kind of hard to infer delivered torque to driver demand on a Gen 4. I finally started over on the pressure and pretty...
Wow. This went weird. OP asked for help to fix his issue with his tune (which is from probably YouTube) and now, OP is arguing that his tune is correct. You can't make this up lmao.
Uff. Enable and tune your VE. Looks rich at idle. Also lower your min rpm reference for the adapts. That is not helping at all either.
I'd say play with it but at the end of the day, Dave aligns with Banish and other OEM calibrators.
I am still battling stalling coming to a stop, or changing gears. For the most part coming to a stop it doesnt stall but definitely isnt happy. Just now I had it stall hard when putting into reverse...
I only looked for a quick second. I wouldnt touch the injector tip tables. OL is going to be adjusted with OL tables. Doesnt matter if commanded matches actual. Its not a closed loop system at the...
2012 Yukon. Yeah I think that is my next thing. I was in-between that and table 15440 to adjust per tq vs rpm.
What decides how much timing is pulled during a shift? I know it is TqMgnt but I mean what actually decides the amount vs desired engine torque. Is there a predetermined tq value the trans has that...
??
Lets start with wtf does that mean. Whats on idle? The engine? Cranking them up. The fans? Your not spinning them faster? Just adjusting the ECT vs DC? Also, there is no log or tune posted
Oh wow. I was surprised the IAT didnt jump after getting into decent boost. Did you try to get the AFR closer to commanded and then pull a bunch of timing out just to see what happens?. Kind of...
Is the sensor pre or post blower? That is a lot of compression. Im surprised it doesnt ping sooner lol.
That seems uber rich. Id also be curious what your manifold intake temps are. Does whipple have a spot in the manifold to put a sensor? 14ish lbs is probably a little much for pump gas depending on...
Yeah Smokeshow. Then I'd try Dave Steck or Howard at Redline, maybe they have a work around being im sure they've seen it before.
Has anyone reached out to Dave, Jake, or Howard?
If the Cal is way out of whack, usually trims are way too slow to react and throw you off. Yeah you can literally comb through the log by hand but for someone new that is going to copy and paste, I'd...
I guess it's been awhile since I've done a gen 3 on the street. Sounds good.
Filter out decel and quick transitions. You can always remove filters after you have a base to see what the ECM thinks it wants.
Put it back into closed loop and adjust the VE with fuel trims. If the trims are off by 5-6 or more then multiply by full. Once you get it tighter, then multiply by half. Use plenty of filters on...
Well. First is to quit picking a fight with a guy trying to help, even though Ed can be a little "straight forward", lol. I can't remember your set-up but is it more or less a Stock longblock with a...
