Need help! with OS for 2010 E38 on LS7

[USA Z06]

Hello to all,
This is my first post and I could use some help.
I've got a 2010 Z06 that the ECU developed misfire problems and the Chevy dealer declined to work on it because it has headers :wallbash:.
(After they checked spark, fuel, compression, manifold gaskets and did a reflash) :bangin:
Sooo I got a new ECU from Scoggins-Dickey and need an OS to flash my modded tune into.
Does anyone have the 12635862 OS?
Will any of the custom tunes work with the newest E38 hardware?
BTW, my module is the 12633238.

Thanks.

Well Kevin, you have the correct ECM at least.
I think your best bet is to get to your Chevy dealer and get them to flash the new ECM with TIS (or find a workshop with TIS), the ECM will need the VATS linked and TIS will put in the correct tune for YOUR car.

Cheers,
Ross
