Assuming you have correctly adjusted the IFR table for your larger injectors there really is nothing else you need to do, EXCEPT keep your foot out of it.

Other than that.. you should be fine.
...

Sometimes the easiet solutions are the hardest to see.

Glad you got it figured out.

You are effectively retarding your timing.

This will give you VERY HIGH EGT's.

This will kill your mufflers and CAT's VERY quickly.

I run 17-18 degrees of timing with 115 Degrees temps at the end of a 4th gear pull when it is 90 outside and don't get any knock.

My car is also a stock motored ZO6 running 7-8 psi on a P1SC
...

I already got it.. it was a bad O2 on the passengers side.

Thanks for the read and the advice... :cheers:

I have an odd problem.

My LTFT were all fine, I have been driving around for a while like they were, with 0 of course at WOT, in Fuel cell 22 (confirmed)

Two days ago I went out and final tuned...

Hmmm.. went back and read my post again... I was sure that no where did it say that my method was either better or the best.

Just making the exact point you were trying to make. There is more than...

Wow.. lots of questions here but I will do what I can.

As far as what the article says... I would take it with a grain of salt. I think all here can agree as a general rule you want to get your...

And this is a such a problem for you why? My VE table is completely untouched as well.. yet mine did manage to knock down over 600 at the wheels.

You don't have to touch the VE table to tune the...

With all of this excellent business advice going to HP Tuners... I am suprised all of you are not millionaires... ::)

Sorry for all of the questions, but am I have a 2002 ZO6 with the IAT in the MAF, so if I remove the MAF do I just install a normal stand alone GM IAT sensor?

Thanks for time in answering these.

That is funny.

I have been using it... so answer this for me then.

If I bought the Speed Density 2 BAR setup for my ZO6, is there still temperature compensation in there even without the MAF?...

Maybe I am missing this and I have tried the search function.

But say for exmple I tune my car when it is 55 degrees outside.

For the winter when it is 30 degrees I can go into the PE vs. IAT...

Thanks.. I will try that approach.

Here is my question...

I have been fighting a randon knock problem too since I installed my headers on my Supercharged ZO6.

I went and logged several WOT runs.. getting varied retard levels.. I...

You best bet is if you know anyone with a Tech one.. or just unplug them one at a time and see if it makes any difference, we were able to find one back injector that I got with this method.

We...

Without logging data I was thinking about my ZO6, which reached the top of the table. I forgot in this application, the truck probably never reaches more than mid-way up the table. I will check,...

Is there any one here tuning their H2?

Have a good reason whey the timing table on this thing is this low?

http://www.usionline.net/h2timing.jpg

Would more timing gain me just more power but...

Mine ran 11.19 @ 127 after only 6 passes.

A little more tuning and some practice on my part and it will run 10's without an issue.

I just assumed it was a V8

12.26 is pretty good for a V6... ;D

Good enough to suprise more than one Camaro or a stock C5.

I used to have a V6.. but it was a Typhoon.

Nice way to get people to help.

If this is the case, I certainly apologize, BUT... for as smart as(s) you are, I don't see you jumping here and offering to help.

If my information was incorrect...

I think you have gone about tuning for injectors all wrong.

With no other changes to he vehicle the ONLY change you should have to make is to the IFR table. I then scale the MAF to bring the...

No I have nothing like that.

I have been using this exact laptop, etc, to tune my ZO6 with for about 6 months.

Thanks for the tip though, I am open to anything.

I thought I would post this up in case someone had a quick fix idea.

I got my software upgraded today to also be able to scan my H2.

I hooked up the cable, started the truck, scanned,...

Well first.. you need to set your LTFT's to somewhere between -4 and -8.. you want to be sure that your car is not adding fuel when you go WOT, it will screw up your WOT tune.

That aside, I would...
