Point a and point b. It will show a current
No this happens everytime I touch the car. Its not like static electricity where I touch it once, it discharges, then wont do it again.
I need to take a voltmeter to the body and see what it says
Im trying to diagnose an issue related to tuning issues I have been having on a 99 WS6. I noticed when I was working on it, that whenever a metal wrench touched the body or frame, I could see a tiny...
I think I may have found the issue. I dont know why I didnt see it earlier, but the car had a Autometer AFR gauge (yes the one that produces a fabulous dancing light show). I took the wire tap off...
The 02's are the right ones. I have never had issues in the 20+ Bosch's I have bought, so I dont think the issue lies there.
Here's a link to the log and config files...

I doubt I need to post a tune, as mentioned earlier, nothing changed when reverted back to stock,...
I've been trying to hunt down a poor mileage issue. The O2's arent cycling at idle, however, the cycle nicely while driving. Bank one at idle will show very lean and start dumpin fuel, which in...

Im pretty sure this car may have an exhaust leak somewhere, but looking at the log file, would it indicate something else?
I did a balance test an all were within +/- 2% of each other, except # 5...
Where can I find this tune? I have looked in the repository and the forums and had no luck..
Wow is that a newer feature? I havent used HPT since about the v2.0
Thanks for the link
Im having issues when I get to the TCM read part of downloading the tune from the vehicle. Its very hit and miss, usually reading it on the 4th or 5th try, but being a Duramax, it takes about 8...
Why is this such a problem with these trucks? I think once out of every 20 attempts, I can get HPT to read the TCM. All other times it reads "TCM Read failed at loc 74C80 Error: Timed Out"
I have...
Nevermind, found it in another section
Whats the procedure for adjusting the speedo for a gear swap in a 1998 Camaro? It went from 3.73s to 4.10s
So they should be the same? Why does the ecm look at both? I thought it only uses idle spark for idle?
How long does it usually take for the LTITs to change when idleing?
Hmm, I had no idea I had to modify it since it was already in there
Someone look at these and please tell me I have something totally screwed up in the tune. The car is surging pretty good at idle and I have spent a few hours trying to hunt down a vacuum leak with...
I think thats what I mean.. Its the very first choice when you go to open a histogram PID.. It will load it, but when I start scanning, it says its not a supported parameter
Car is an 02 Camaro A4. Im trying to log my RAF in the histogram, but it says the parameter isnt supported. How do I get it working so I can get my RAF tuned correctly?
Im beginning to suspect I have an air leak somewhere. Sometimes at idle it will surge real bad in gear and in park, even when I lock the timing, AFR and IAC. It also whistles, sort of like a...
Ok, so this is my first car completely tuning from scratch.
It is a 2002 Camaro Conv. A4. Mods are:
