Much obliged!
I'm looking for some help. I did some tuning on my LS1 and now want to work on my stock 2007 z06. The LS7 doesn't have a VE table, so what the recommended histogram for checking LTFT?
RPM vs ??...
That was fast....I just figured it out.
Thanks!!!
I uninstalled 1.7 using the HPT uninstaller. Installed 2.x but now I have lost the Flash program....
What's up?
On a recent emissions test on my 2002 Camaro SS during the OBD II test I received the following code:
Vehicle on-board diagnostic system was not ready for testing due to the following unset...
Fried cat is very tasteey. :cheers:
Thanks again for the advice!
:'( I'm already crying. Has anyone heard of a fried cat using long-tube headers (with COT disabled)?
I'm not sure how the COT condition is triggered. I have longtubes with relocated CATs that are way back, and you would think they would run cooler. I also was told when I had a recent emissions test...
Check out the COT factor....It was controlling my fuel air multiplier.
Well, the problem definitely was the COT. It was pegging on the max enrichment value.
Does anyone know how the PCM determines the COT condition? If anything, I'd expect a low temp on the cats...
Thanks jimmyblue, I'll check the cat overtemp. Any other contributors?
I set my VE table using the procedure defined in the sticky in this folder and left the MAF table stock. I'm trying to adjust the air/fuel ratio at WOT but modification of the PE multipler vs RPM...

Did you finally get this to work?
My approach would have been no driving at all for 3 months, and the kid pays for the ticket and insurance increase.
Whatever works!
Our "legal" profession has f*%ked up just about every facet of our lives. :'( :banghead:
I'm colorblind but have learned to cope. Having selectable colors would be a nice perk. :cheers:
I shipped mine out on March 14, via priority mail, and recieved it back yesterday.
Good Job!
Yes, but read the licensing agreement...I recall that you have to uninstall it when you change computers.
I just put you on my Spam list.
Has anyone heard anything about turn-around time?
Regarding the use of rear vette O2 sensors for cars with LTs. I changed out the passenger side only and did some logging. I didn't see any real change in the switching behavior between the...
Try using the brake and select the gear for the RPM range. Braking will load the engine...
Good news! Is the USB interface any faster?

How does your oil look? If it looks weird or foamy you may have a head gasket leak.
