Having trouble with starting cold temps
Read my sig for specs on my '01 Formula. I can seem to get this motor started when the outside temps are below 60F and even then it doesn't want to idle until the motor warms up. I am not sure what to try next to get it. It's like I need to mess with the "choke" like on a carb. I tried an old tune with the VE higher. It atleast fired, but I had to hold the TP to 16%. I would "idle" at 400rpm, but wouldn't accelerate. Please help.

Today it was alittle colder and I had to open the throttle to 30-50%. During cranking with the Scanner, I noticed that the timing was at 13degrees, the factory o2 sensors were at the bottom of the voltage, but the wideband is telling me like 11:1. It is still not wanting to accelerate part 400rpm on startup. So I am really confused on which way to go on the recommended tables to help out.
Oh I forgot to mention that I removed the supercharger so that I can redo my N/A before I put the blower back on. I know the blower might have helped to get the airflow up for startups. I keep looking on the HPT tune repository, but everyone with large cams use either the FAST or LS6 intake. I would like to get more advice.

Have you adjusted the Startup Airfllow Correction and Startup Friction Airflow Correction tables? Both are critical to cold start (especially the Friction table) idle and can be adjusted according to ECT. I had to increase the values on those tables alot for my setup.
