Let me check the garage........nope, still just a little Cruze in there :D
Probably your best bet is to figure it out based off the 2013 & 2014 Camaro ZL1, it runs the similar OS's so it will be the same ECM. I bet you will find the part number on line for that car.

Hi Ross. Went under that assumption already and have a brand new zl1 ecu. Tried flashing a gts program and it complains it's wrong hardware. Then I tried a zl1 and it went in fine. That's when I assumed they were different.

Ah ok, that does seem very odd, however, GMH TIS does that a lot even though the right ECM is on the bus, VERY annoying indeed and I don't think there is any way around it. Plus that HDW number is not written anywhere on the ECM case.

What OS is it using ?

The 2013 Camaro ZL1 & Cadillac CTS-V run OS12653669 (E67). The 2014 Camaro ZL1 and Cadillac CTS-V run OS12656245 (E67). The parameter addresses of these calibrations appear to be identical (despite the change in OS). They use E67 Service # 12633264.


Cheers,

The Holden runs OS 12656942, but that is essentially 12656245 with minimal changes, so I am betting it will be Service # 12633264.
I don't think it has anything to do with the ECM, Holden's TIS2WEB constantly gives HDW mismatch errors (even though it is correct) or 'No response' errors, its a mess, I don't know how the dealerships get by.

Yes it is a weird thing the old TIS2WEB LOL... well I am going to leave it with a ZL1 calibration and then do a write entire over the top and hope that all goes well to get to the desired result...

thanks very much though for the input guys very much appreciated
