        On a cold start mine will idle at 1200, once warmed up it will drop to 800-900..witch is where I set it at the throttle stop because thats the "sweet spot" where the engine doesnt vibrate the dash with the poly engine mounts all around.

        Did you adjust your throttle stop, IAC and the VE table at all?

            I know my idle is extremely low (always has been since I bought the car 5 years ago) but I idle perfectly at like 400-500 rpm, with no issues. If anything, it idles better now on mspnp than it did on the stock ecu.

            Cold starts when it used to be winter driven would be like 1200-1500, now that 'cold' is mid summer its like 1000-1200 max.
