[QUOTE=Brice;336742]Which 90mm do you have ?
Is the blade silver or gold ?
The blade is silver. It's a ported GM 90. For road racing, downshifting and braking are really important. Go fast...
99 Corvette with the stock ECU. It has had this throttle lag every since I built the 6.2L race motor with the 90mmTB and 233/239 cam. My Desired Pedal Area Normal is in post #1, Desired Pedal Area...
My C5 runs great at WOT with a 233/239 cam and 90mm TB, NA. Overall the tune is good, VE and timing tables are tuned. The only problem is throttle response. If you are cruising at 3000 rpm, and give...
My "Desired Pedal Area" is 100 at the top three cells. Should I change anything here? I'm looking for better throttle response.
There is a strong warning that you may render the PCM permanently...
There is a setting for PE mode that is a % of throttle position. Mine is set at 50%.
The numbers in the factory PE are usually set pretty rich. When you start tuning your PE to lean it out, you...
IAT intake air temp? and what is bias? There are so many tables and so little information on how to adjust, I'm lost. If you can give me more info, I will check it out.
Sorry to jack your...
An 83lb injector? That sounds large, is your car boosted, or sprayed?
Wow, that is one killer project car. Sounds like you have put a lot of work into it.
My C5 LS3 with an LS6 top end makes 480rwhp, I thought that was fast, you are way beyond that. I am SD tuned...
This must be an awesome car. How much cam? How much HP does it make? I have an LS3 with a 233/239 cam that has an aluminum flywheel. It takes some revs to get it moving from a stop sign. It has...
Yes, on my other motor, the timing tables were set at flat 25 over 3000, and that is what I get at WOT. I had to make one change when I would push in the clutch to shift, it would advance the...
My LS6 had 8.9 Dynamic Compression. That's about .9 too high to run pump gas so I had to limit the timing to 25 max to keep it from knocking at WOT. That's with a good tune 12.7 A/F at WOT. At lower...
Did someone have a different motor in the car? It sounds prety strange if you have an LS2 to have a cyl volume of LS7. It may be tough to tell what impact that has on the tune.
Do you have the smell of raw gas, or fumes? I ran without cats for a few years, but I installed high flow cats last summer after I got tired of my eyes burning at every stop light. I like it a lot...
I hate to be a dummy, but where do I find this tune repository??
I had a forged LS6 with a 233/239 cam and 8.9 DCR. I could only run 25 degrees timing and I had to run half pump gas and half 100 octane race fuel. The knock only occured at WOT usually after a gear...
I have forged pistons, a big cam, and headers, I have read that all may contribute to false knock, but that never happens to me . When I had a high compression motor, I had a lot of knock issues. I...
Just a wild guess here. On my 99 C5 there is a line to the Throttle body that pulls vacuume on the fuel tank, if that is disconnected, or not functioning, it could be pulling fumes.
Max is 639, set it there.
What do I change to help with a cold start on a car with a cam. I have a 99 Corvette with a LS6 motor that has a 233/239 cam. When it is cold it starts and dies, starts, dies etc.
It take three of...
IT WORKS !!!!!! I reloaded the sodtware and updated to 2.22 and now the data logger is in the menu. Thanks to everyone for the input.
We are making progress. I can scan now, I loaded the default config and it works, the config that I copied from my old computer must be bad. Now the scanner works, but it does not have the Pro data...
XP, it should be easy, it is an HP laptop. I have uninstalled and installed the HPTuner software, loaded the serial to USB driver. It connects to the car, but won't scan any data. Is there some...
Now I can connect, but it won't scan any data when the car is running.
I can find the license, but cannot log any data. What's up??
My Scan menu does not have the Pro Data Logger either. This all...
OK, download USB to serial function, download HPT drivers, reboot, still will not work, uninstall and reinstall HPT, reboot, OK, OK, I think it works finally. Yes, it found the license. :worship:...
