I think the same change was made to the 2009 E67's too, Chris, do you know if they got a new part number?
The CTS-V is all 2009 based OS's, I think they are up to 3 OS updates for that car already
Cheers,

From a hardware perspective the 09 Throttle bodies on Vettes are quite different mechanically and electrically from the <09s. The 09 TBs can not be used to replace the previous 90 mm version for 05>08. Could it be that the OS is rejecting the TPS change?
The TBs look similair but are not. New part#, orientation and TPS best I can tell.

Bruce,
Anyway, I've come to the conclusion, and I may be *way* wrong here, the reason the '09 TB will not work on the '08 vehicles, and vice versa, is that the ETC Area scalar needs to be changed inside the calibration. The '05-'08 C6s (and '05-'06 GTOs) had "4725.0000" as a factory value, and the '09 vehicles have "5636.0000". Maybe Ross can answer this (if it hasn't been already)?
Ross,
Speaking of, I'm in the process of obtaining an '09 processor with '09 LS3 calibration and installing it onto my '08 Z06. Why am I doing this? It's obvious if the car is going to be forced induction: 15k Hz MAF range WITH 127 #/hr IFR range (the IFR being key, so no more scaling down airflow values). I'm fairly sure everything will work properly once I make the necessary changes on the '09 LS3 calibration (basically copy/paste over my '08 Z06 parameters), at least I hope it does. Your thoughts on this, and the TB info above?
Thanks in advance!
RWTD, I don't think it will work.
You will need to get some sort of confirmation on the differences between the 08 and 09 pedal and throttle, if they are different then you will need to swap them in too.
I did look at changing the 2006 - 2008 ECM code to allow the larger injectors, but it's a mammoth task and probably won't happen.

Ross,
Thanks, that gives me hope. It sounds as if you're assuming the same as me, the '09 LS3 pcm just might run any '06-'08 LS2/LS3/LS7 (provided one swaps in the '09 pedal/throttle assemblies, if they are needed). Is that way I saw?
I hear ya on the IFR limitation issue. I know it's a monumental task at changing tons of code to allow for such.
Thanks again for your help. It's greatly appreciated.
gmh308, yeup, I agree with you and Ross now. I'm going to start digging up part #s tomorrow.
Sincerely,
James
