Yes it misfires above that point as well and then the HPT scanner quits logging at the same time. We don't have the original coils, I will try to track down some OEM coils and try that. Thank you for...

I believe that was the TCS removing timing. Here's another run that is WOT in a higher gear so the TCS was not a factor after 5200 RPM.

I have a 2010 Camaro SS 6.2L NA that a friend brought to me with an issue of cutting out above 4500 RPM. When I drove it, the engine seems to cut out if the RPMs are above 4500 and the TPS is roughly...

I was tuning a (2004 Cavalier)car today and everything was fine. I went to connect to a (2016 Silverado) truck and couldn't get the vehicle to connect to the interface. I tried connecting it back to...

Ok so we have the o2 sensors working now but we are getting a very intermittent back fire through the exhaust. I feel like the tune is ok and that maybe there is a sensor issue or something else....

I wanted to follow up on this. My friend took the harness back to the company that made it for him. They tested it and found that they had left out the ground circuit for the o2 sensors. He will have...

We got another ecu from the salvage yard and put it in and the tach and gauge worked fine again. So we tried tuning that one, and again the tach and oil pressure gauge quit working. I have never had...

I did a tune on a 1998 Cavalier 2.2L. After the tune, the tach and oil pressure gauge don't work. Has anyone ever had this problem, and if so do you have a solution? Any help or feedback is greatly...

Thank you for the info! I tried hooking the ground to MVPI #6 and it worked. The display in the channel went right to 14.6.

For some reason it is not showing up in the chart?

Again, thank you...

Thank you for your reply! I have attached the log for you to review. I don't get to choose between Lambda or AFR when setting the parameters.

Your help is much appreciated!

I have a Dynojet Wideband 2 that I have used in the past that worked fine. I recently upgraded to the newer version of scanner and for some reason I can't seem to get it to respond. I have tried...

I did the license upgrade for 2003 Chevy Cavalier to have unlimited tunes a few months ago and have done a few since then. Tonight I went to do one, and it shows up as a 2003 Cavalier when I read it,...
