ECM programming for slightly modded 00 LS1 I have a standalone GM ecm (tuned for ASA racing so I'm lead to believe), p/n 12480112, and applicable harness for a 1971 Land Rover project. The ecm is non-emission and no torque management for the 4L60E. The engine is a 2000 T/A LS1 with a LS6 intake, 2005 GTO camshaft (204/211 .525/.252 116.5), and stock s/s corvette exhaust manifolds. I've not started the engine over yet the chassis is not completed to accept it. I can find no information on this ecm other than generic data regarding it's intended use. My question is will additional programming be needed to better match the ecm to the motor or will this be adequate as is? I This is not for intended street racing so topend performance is at issue.

This is chevy's LS1 ecm for offroad/racing (non-emissions) uses. It is programmed without any emissions (pre/post cat, fuel level, evap, etc.), VATS or transmission torque control. All GM performance suppliers sell this ecm but fail to provide any details as to it's application other than the LS1 engine. I am mostly concerned over the increase in camshaft lift/duration as the other items are very small changes. I have the stock ecm but it would require programming that the performance ecm already has in place.
