Ive been working on my cold start. The issue im having is when i first start the car the engine comes up to around 1500-1800 rpm then quickly drops to below idle and surges for few seconds before coming back up to around 1500 rpm again. Where do i need to look at to correct this?

most likely startup fuel enrichment. I am still working on this area of my tune as well and just recently reset the isc multiplier back to the same as the A9L2 and focusing on getting the fuel perfect first. I have screwed up the way I was making adjustments and got the isc multiplier all jacked up. The adjustments in both of these table are .008 increments and I now think making smaller adjustments is better.

When i get time this week ill check that out.
