[QUOTE="patooyee, post: 537949, member: 483"] I don't know about that. As long as the O2's are working it should not run lean. Yes, the main VE tables are tuned at op temp but there are a bazillion modifiers that modify the base fuel tables based on ECT. The main VE tables are only like 1% of the overall fueling calculations. Even in open loop there are fuel modifiers to compensate for ECT. I ran my LS2 without a t-stat and was very happy with the results. It always stayed around 200-210. Maybe over the lifespan of 200,000+ miles not running a t-stat could affect something in an OEM vehicle. But the average LS in a dedicated offroad rig probably doesn't even see 10,000 miles in its lifetime. [/QUOTE]
