I have a 2002 C5 zo6 that we just swapped a built 4l60e auto into had a few issues with getting the correct tune in for it to shift but thats all taking care of now.

But i had a quick question...

Here it the latest log. This truck is driving me crazy

I have a dip in AFR when Dyn Cylinder air G/cyl increases but idk what is commanding that fuel. Rpm, Maf, Tps all basically stayed the same but the g/cyl increased and it dropped the AFR from 12.5...

do i leave the WOT max entry disabled? Thanks for all your help

Yeah i moved my kpa to like 95 and moved tps down to the 40s and that helped it out alot.

What exactly am i doing when i move the Dynamic Airflow High Rpm to like 2000? Never really messed with...

Its not positive at cruise but when it gets around half throttle, when the manifold pressure does exceed vacuum and builds like 5lbs of boost it dont seem to like 14.6 AFR's. I have PE coming in a...

Heres my tune also

In my tune I am trying to add fuel under light boost while cruising and small accelerations. But all the fuel i add the stft pull it right back out. How can i stop this from happening?

Alot on this truck was messed up from the last guy who tuned it. I had to go back to a stock file and transfer stuff over to kinda restart. The truck was in the 14s AFR at wot. It got like 7 mpg...

Okay thanks man i will try and work on that right now. Its only on cold start it strange.

bump

The truck is running good but it has a funny start up, and when you go wot the let out the truck kinda feels like it is missing for a few seconds then it clears up.

Here i have a 03 Silverado SS with a Magnacharger 8lbs, small 212/220 cam, mild head porting and bolts ons. I tried tuning it on the maf but it was right at the end of scaling and wasn't getting the...

Sounds like what im gonna do. Any of you guys ever had any luck running that cobalt ss map sensor?? Im hoping this thing works out and i just have to worry about tuning it now. Thanks for all the...

Alright but then its SD only right?

I have a 03 silverado ss 6.0, heads, cam, supercharged 8lbs. Anyways when i got the truck it had 38# injectors the were maxed at 120% dc, stock map, and every table in the tune was destroyed...

Well i inputed the only info i had and it seems to be doing fine. Heres a log if anyone is interested. The only problem im having is it looses rpm and dies out at random times. I havent went wot...

When i input injector flow rate. Do i inter the rate at 43.5 psi which is 60lbs or do I input the 58psi flow rate?

Im new to the hptuner world i have been spoiled by value files for injector scaling on other programs. But i bought some Delphi 60lbs injectors for a 03 Sliverado SS.

How do all you guys who street tune, tune the AFR without a wideband? I have seen a couple local people who street tune all there cars but i was wondering what they used to get there AFR close.

I have a 06 silverado that had a 5.3 vortec in it and now someone swapped a 6.2 l76 into it. I was wondering how i find out what injectors came in both do scale the injectors? Thanks

Any start up tuning help???

I have a 07 silverado that had a L76 6.0 swap. It has a 24 to 58 converter box.
The engine was installed by someone else and the tune was done by someone else.

The truck runs but turns over...

Try disconnecting the battery for a few minutes, then hooking it back up. Sounds crazy but it worked for me.

Why when i try to right click and undo something in the spark table it comes up unavailable. :banghead: Can you only undo everything??
