I'm going to hook up a WOT switch on a 2008 Corvette Z06 - does anyone know which color throttle body wire registers the voltage (0-4.5 or 5)?

Thanks midgetracr for the link. Heres one for you WinPep7.

I've got WinPEP7 and have been using it. I just wanted to know if anyone knows how the STD correction factor is calculated.

I understood all of that - I was asking what is the formula for STD. The SAE formula was easily found but what is the STD formula?

Went to a dyno (DynoJet) over the weekend and the operator at first could not get the O2 to start sampling until almost 5000 RPM's. He was telling us to go and then pushing/clicking some button at...

Did you get a stock baseline on the car before you started? Was this number you posted with a tune only or tune + headers, etc.?

Thanks Bill - I didn't realize there was a "copy over" feature. All of the posts I Googled (from several sites) said to cut and paste all of the settings which would be a huge hassle in this...

Ok Bill. First of all I didn't know it would fry the PCM - if I did, I wouldn't have been asking. Secondly - is there something I don't know - there have been tons of changes to the other tune - how...

My buddy at work has an 08 Z06 with cam, headers, cold air and a tune. My neighbor has the same car and has just made the same mods. Both are licensed HPT users. Can they write (calibration only) the...

That makes sense - thanks Frost!

Resurrecting an older thread here since I have a related question. Is there any adjustment/calibration needed or available on a DynoJet for the O2 sniffer? The reason I ask is that on a recent trip...

Will it also work on a 2008?

The Corvette chief engineer said their best test driver was 3 tenths to maybe a half second off vs his same performance with the launch control so I guess they disagree on this. Not wanting to argue...

Thanks for the info LazMan.

I noticed my A/C compressor (2008 LS7) was shutting off when my fans came on close to full speed - not sure exactly when but over a certain coolant temp the A/C shut off. This was happening on a...

I just made this same change to my 2008 Z06 and saw no detrimental results so far. I had always heard they were way too sensitive in 2008 and the proof was that GM lowered the sensitivity in 2009. ...

Can someone post up a stock 2009 LS7 tune. There is one out there in the repository but I am still unable to open it since January and haven't seen any new versions on the site since June 2008. ...

No, I don't have it. Is it available to anyone?

Can someone PM me if you have a stock 2009 LS7 tune or - better yet - upload it to the tune repository. There is one in the repository and I downloaded it but can't open it. It acts like it's going...

Thanks for your help WS6FirebirdTa00. I really appreciate it.

He is using the LS1 MAF and it's an 01 SS.

Thanks for your reply. To answer your question first - I'm more of a hacker than a tuner. I messed around with the tune on my previous C5 Z06 and got great results after many mods (cam, headers,...

A friend of mine transplanted an LS6 to a SS Camaro (automatic). He did not move the LS6 computer over. The car starts and runs (barely) but fall on it's face performance-wise. Logically, the...

It was only going to be a "write calibration" to tweak the spark tables.

Okay - thanks for the information Bill. I want to make sure you know that I wasn't trying to skate around any licensing issue - I was just trying to help a friend out and I do have a license for...
