Probably can't accept that anything is wrong on what they paid money for. Then they'll just rough in idle air so it doesn't flail while warming up...

With respect I dont think you understand regression. What you are showing here has nothing to do with regression. regresssion is not fitting data to...

When I had that image opened I tried panning it around lol. Nothing about the adapters stands out in that VE does it? I was thinking certain rpm's...

What is the status of this project? Why the concern for startup fuel before VE is tuned? Re-enable closed loop then do so.

@smithspeed what classes have you taken? I'm curious to learn more on this platform.

Okay after doing a bit of reading and a bit more understanding I think I have fixed some things that were pretty bad with this tune. Thanks Alvin for...

Ok I'll put it in 4x4 and take a peak

What is his normal highway speed though? Some data logs would really be helpful. We need to see how the truck is driving to see if anything stands...

How recent is "recently"? If an engine starts to act up within 5 or so drive cycles, it's possibly the tune. But if it's been weeks or months,...

If your truck is 4x4, when in 4x4 (or at least 4 low in my truck), it uses Map B. For trans shift schedules and converter lockup, mine uses normal...

here are the most recent log and tune, car just got a new motor but same cam setup nothing changed. Temps out are like 5 degrees im not sure if that...

You might want to find someone that tunes those trucks and buy from them. SOmetimes they will knock some price off the tune if you buy everything...

Oh now you listen ;)

I tune a lot of trucks and the first thing you find when street tuning often and then going to the dyno....the real world load from the vehicle's...

I hope we arent forgetting that not all cylinders burn equally. Here in our stock pcm tuning world we are running 1 wideband, 1 bank, no egt. I find...

Awesome

The torque tables are incredibly easy to do. No reason not to rescale them
