Thanks a lot for the tip mowton. I figured it was quite a bit richer, and 12% sounds about right. My AFR used to be in the low 11's under boost and now it pegs my wideband at 9.9 under boost, so...

I have had my turbo 5.3 tuned for a few years now and it has run very well. I originally tuned it to run a constant 58 psi, so my VE table is based off of that. I recently switched my fuel system...

Been working excellent in my car with that data. Got it from a very reliable source!

I run my car at 62ish PSI fuel pressure though, so the only thing you may need to change is the IFR table...

I just noticed you replied! Had just about lost hope haha. I will check out the tune in the AM since it's late now, but any insight you can give me on what was the issue? I did notice you greatly...

Heres my latest tune file. Injector data was from Greg's DVD so it should be accurate, although something is way off if my voltage is messing with the AFR this much!

Anybody? Someone?

Upon playing with it further, I have gotten the driveability pretty much dialed in, but the idle is all over the place. Coming to a stop light, it will idle fine, right...

I have motoron 60 lbs injectors in the car and have tried adjusting everything such as all injector data parameters as well as my VE. I CANNOT get these damn things to idle consistently. When cold,...

Not sure lol. I just started tuning with HP tuners and I had nothing to do with setting up the original tune. The car runs off the MAF under boost and it's re-scaled to support around 700ish HP. ...

I had a buddy tune my car initially and the way he did it was to re-scale the MAF to be able to support more power. The car is a stock 5.3 with LS6 cam, 317 heads (8.6:1 comp), LS6 intake and TB,...

EDIT: Added my current tune I'm using during VE tuning.

While tuning my brother's H/C 6.0, we are getting KR at odd points during normal driving usually off a stop light at around 2K-3K rpm in 1st gear. AFR seems ok, and timing is around 30* and the...

Hey all. Found this while searching for VE tuning info, and it seems like an extremely well written and easy to follow instruction guide. It shoes how to tune the VE and the MAF sensor separately...

Thanks a lot blownblue z06. I didn't have the "AFR commanded hi res" inserted in the table. I'm going to try it when I get home. I'm still an amateur at this stuff, but my mind has been getting...

I have AFR inserted at the very bottom of the table where I added the wideband. Do I have to add it to the top section as well?

Basically, I just want to know what you would do to configure and...

Like the title says, I have HP tuners pro, as well as an NGK AFX wideband. I've heard that you can do VE tuning by setting the wideband up to view the AFR error histogram, and this makes it a snap...

I actually saw that table and took a lot of the timing change out of it. I believe I currently have it set at about +/- 2* of timing for every 50 rpm change. Haven't tried it yet on the car, but I...

Fired the car up this afternoon, and even though the idle timing tables all match, the timing still seems to jump around quite a bit. I'm not sure exactly what the problem is there? Timing also...

Thanks for the info gagliano7. I'm going to fire up the car this afternoon after work with more stable timing now hopefully, and I will do the idle config then. I did notice the IAC counts as well....

Bit of an update to this. I followed the big cam cold start instructions in this thread here... ...

I started another thread with two log files and the tune I have currently if you would like to take a look. Thanks for the reply!
...

Thanks for the link C.U

Anybody care to check out the logs and tune? Kind of sucks having not much experience and trying my hand at tuning a pretty wild heads/cam 6.0 off the bat! I'm determined...

Any info on it? I've heard it mentioned before but do you know where can I find it, and how to use it? Thanks for the reply bud!

Hi all. New guy here trying to get a H/C motor to run decent. This engine is in a 91 trans am and the old setup was a mostly stock 5.3, which is also the base tune I'm working off of for this new...

As the title says, I'm working on the tune for my brother's heads/cam LQ4, and am using a base LS1 F-body tune to work off of. I've read through all the idle tuning how-to's on the HP tuner forums,...
