Went to gear change on a 1998 SS Camaro and got a checksum Validity error. This is the first time that I have had anything like this come up, what's the deal ?? I am suppose to email this to hp support?? What's that web address ? Thanks for any help!!
1998 SS Camaro M6&&1988 GTA LS1 A4
Sounds like a hand held tuner or old mail order tune is in there.
Our software will not touch a calibration if the checksum is bad or altered.
You may have to re-write a stock OS back into it.
