Hi guys,

Here is my problem : I have a GMPP harness with an E67.
Actual OS is 12638778, engine is a LS7 on a Corvette. I use an AIM dashboard but it's impossible to get the datas from ECM (RPM, Oil gauges...) from the CAN bus.
The dash use a Corvette ZO6 LS7 protocol so I think that I need a Corvette LS7 OS that could be compatible with the E67.
I have another Corvette with another E67 and Dash, the OS is 19211212 and it works very well. I read that it won't be a good thing to write this OS on the other...It seems that it could fried the ECM
Does anyone could have a correct OS for me ?

Thanks a lot,

Michael
