Knock sensors are on the side of the block on this one. I am going to order a new harness extension and see if that clears the code from coming back...

I just wanted to say thank you for this post, as I begin my journey into fueling of larger injector's this was invaluable information! Even with FIC...

You have both knock sensor codes active, that is why the knock retard is pegged at 8 degrees and pulling away all your power. Fix the...

No, not really. The cylinder volume is what matters, that is telling the computer how large the engine is.

Wow. Thank you so much for the reply. That's given me a few options to try and routes :-) to follow. I will place a session zero time at column1...

I have a lot of questions here. What happened to your VE table and MAF curve?? What injectors are you running and what is your fuel pressure?...

HPT never claims to be calibrators. There a software development company. This doesn't mean that they have no idea of the logic works as years of...

I think we had one of the o2s switched around. It dialed right in after that. Now we need to fix the idle

Thanks redline, I often do take the side of caution and completely leave stuff alone and stock since I feel like it could inadvertently change...

You are probably correct, but I haven't looked at the file.

Here is the pull we made

Sure, share them

I started ANN tuning the car and its pretty dialed in at idle. Fuel trims seem legit but when you blip the throttle it hunts to find it. Also, it...

Does changing the engine type from 6.0 to 5.3 change anything else in the program ? I'm still trying to figure out the transmission setting . ...

Thanks, Good information .

Like 5F said, put the Stoich back to stock, and your injector flowrate back to stock. Every 98-00 model 454 that I've tuned has a 22.2 lb/hr...

If you'll post your tune, we can help you with it.

I am going to check fuel pressure tomorrow.im also going to get some brake cleaner to spray around the throttle body and intake manifold.. I have a...

Nobody said anything about a cam, but thanks for the tip.

Any one ?

2002 and 2003 Silveardo use different computers, so you couldn't do that. A 2002 uses a P01 and a 2003 used a P59 computer. If you want to copy...

I'm trying to help you here. You've told us that this swap is a very bare bones swap with many stock parts. If you are still using the factory...

I do have a slight exhaust leak on the drivers side manifold to ypipe but its very faint and goes away when warmed up

The log says it's going super lean based on the o2 sensors. Once you get really far into the throttle the o2 sensors take a nose dive to under 100mv,...
