Sorry to bother the forum, but I have not been to find the file to turn off the VATS in a ECM37. I would like to program it as the stand-alone controller for an LE5 engine. I've looked in the system folder, no luck. The OS folder doesn't seem to have any tabs for it either. Can it be done? If so, please tell me how. I should add that when I open the OS folder, it is completely blank. From what I have read, I was expecting to be able to access the VATS when the OS folder is opened. Everything else is normal. The ECM is unlocked, I can change the usual stuff and view diagnostic codes etc. I would appreciate any insight, thanks.
