Nevermind… I’m a dummy �� there’s a 4 second delay and I didn’t run the car long enough to for them to turn on.

I?m trying to tune a gen iv ls to have the fan on all the time because it wasn?t wired with the correct AC relay that turns the fans on with the AC. I?m in Florida and the AC is 100% on every single...

I tried with both TBs and the 15101848 wouldn’t control either. The 10379038 controlled both. But somehow I can’t connect to the ecu with hp tuners anymore. So something is definitely fubar. Might be...

Looks like both of the ecus are screwed. Can’t connect with HP tuners. No clue what happened there. Know where to get a pre-programmed one and just start over?

I have one of those 15101848 pedals and it wouldn’t operate the TB at all. But I may have the wrong TB on there. I have a 09 silverado TB on the way, so I’ll try those two together.

I just ordered a different TB and MAF specific from that vin associated on the ecu. Fingers crossed that solves it.

My tuner said he had tuned for those specific parts.
Can you suggest part numbers that would work better?

Well looky there! I’m pretty novice at this stuff. Learn something new everyday. What would be my next steps to fix this? Do you think it’s in the tune or a hardware/wiring issue? The harness is...

Where are you seeing the P1516 code? I only saw P0621 and U0140

Yes I did a write entire.
It did not come with a pedal or TB I am using:
Pedal GM 10379039
TB GM 12670834
MAF Delphi AF10043
MAP AC 12592525

I?m not certain how to check this, is x1 18 one of the harness pins?

Is it possible an incorrect pedal could cause this? When I move the pedal it does move the TB.

I think the tune file was older, I did try loading the tune on another ecu (unsuccessfully) but that wasn?t this log.

I had someone from this community write me a tune and I uploaded it. He?s...

Hi everyone, I've been battling with a gen IV 6.0 build for a long time now. I originally had an OEM harness reworked and ended up with tons of problems and it wouldn't ever run. So I finally broke...

I just switched ecu’s. Loaded the tune and still same story. The car will start and begin logging. After 10-20 seconds the data stops streaming.

I loaded the original and back to the custom file, same results.

I did a Gen III 5.3/4L60e swap into a 38 Chevy and it runs decent but I can?t get a good log to tune further.

When logging data it?ll capture everything before I start the car. But once it?s...

Yea buddy! �� ��

Not gonna lie I’m a total noob with tuning. I have a guy that does my harness builds and basic unlocking and tuning for standalone setups but he doesn’t have anything for a supercharger. Once the...

Hi everyone,
I looked through the repository and found no supercharged 6.0 files at all.
Does anyone have a tune file I can use as a starting point just to get the motor running for the first time?...
