Well after thinking about the idle issue some more I went out and played arouund with an idea..When I got the motor fully warmed up, I disconnected the stock IAC valve. I had drilled out the plug that covers the throttle stop adjustment screw, and turned the screw in a bit to get a little bit faster idle speed. It now idles around 900-1000 rpm, and it's MUCH more consistant without almost any surge at all. The only downfall to this is that during a cold start, you will have to keep your foot on the gas pedal to keep it from stalling, since there is no more "fast idle" when cold. I'd really like to incorperate a fast idle valve onto the stock TB, and I dont think it would be that hard to do. The MS is able to control one of these valves, so it's something I may try.

I think when the stock coilpack is disconnected from the ECU, the ECU starts to freak out and cant keep the IAC at a steady control rate, which is causing the idle surge in rpm.

I also took the car out today for the first time runnng full spark control, and it ran really, really well. I ran about 20-23 degrees of timing at 10 psi,and it feels pretty damn good. A/F was around 12.0-12.3:1 also, which is perfect for 10psi on my setup. Got absolutely NO detonation either. Stock advance under ALL boost levels was always around 17 degrees. This is nice, since now i can put in a few more degrees of timing under lower boost. Low boost feels damn good now, and pulls very smooth. The Megasquirt is just f'n cool
