Hello, Im having a problem with my 90 corvette the exhaust it popping loudly and more frequently when rpms increase. I was wondering if anyone could look at the short logs I took and see if there is anything blatantly wrong.

What did you use to log this? I am just getting into trying to tune my 90 vette and can not seem to get any program to connect.

The attached Log File Analyzer.zip is very helpful for $8D.

The data log needs to be exported to a .csv file. The instruction are included in the .zip file. Intermediate to advanced Excel skills will be very handy to have when using Log File Analyzer.

Logs are way too short to determine anything. If logs are correct, the REV 8.1 log is way lean 150+. Idle log is all open loop and NG.

The 90 Vette has challenges getting connected to.

TunerCat shows the 90 Vette is supported by DataCat: http://www.tunercat.com/

DataCat offers a free 10 day trial period. Likely DataCat is the best option for a factory stock 90 Vette.

I data log my 90 corvette all the time using Tuner Pro and ALDLDroid, try using this ADX file, it should silence the ccm. https://drive.google.com/file/d/1o1kAk9fSniWY1RRhuXOoWujZeslkxADQ/view?usp=sharing
