Hello again.
Im trying to tune an 06 z06 but Im stuck at square one...I cannot even read the stock tune out of the ECU. The car is a pre-production media car used by GM before the official release. We have a pretty good history of the car and can confidently say it has never been tuned with any other aftermarket device, came into my hands bone stock.
When I try to "Read PCM Calibrations" and select the e38 ECU from the drop down it will connect to the ECU, download the calibration(about 4 minutes), disconnect from the ECU, and ask you to turn off the ignition. After all of that a dialog box comes up with the error "Range Check Errror" The only option at that point is "OK" and it brings you back to the main EFILive 7.5 screen with out the downloaded tune.
I have already updated to the latest 7.5 build (130), 8.0 is up to date build 110. Boot block and firmware on the V2 are also the latest versions as of today.
I can connect to the car and data log with the scan tool program just fine. I was also able to get the following information out of the ECU
OS: 12614682
Cal ID: 12601695
BCC: YMBK
Engine OP: 12605204
Having said all of that I think the issue leads back to the fact that this is a pre-production car. I also noticed with the scan tool software that it decoded the vin and reported the engine as a 4.6L v8 and not the 7.0L v8 it actually has. The car has a "y" for the engine code (4.6L), but an actual production z06 should have the engine code "e" for the 7.0L.
Im not sure if that is the issue with this car but it sure does make sense. How would I go about this?
Thanks
