Cold start
It was about 13 degrees here this morning and I have the afterstart set to 12.5. Started in 2 crank turns and idled perfectly, waited till the car was above the C mark and went on my way with no, none, zero, nada problems. Cant wait for the 50 degree weather next week. Gotta love WI.

I was pretty amazed myself. I had the thought in my head of all the AEM guys complaining of the horrible cold start issues before I turned the key. Didn't even have a problem tonight with 4+ inches of snow on the car.
No doubt the Afterstart feature got my Attention on this product, a real common issue with my blowthrough setup is the lean cold-start idle, all evos do it even with the stock MAF, for some reason the enrichment isn't enough to get a good open loop idle in cold weather until the O2 sensor heats up and the coolant temp rises (which seems to take about 10-12 minutes in cold weather)
The downside is that the afterstart is always on. It is too bad it can't take a reading from the AIT and determine whether to use it or not, or a leaner version. If you run the car, shut it off, turn it on- it will run rich for a bit.
Jack from L.I. does not care. Full throttle from MI and Dryad from up north too. I'm sure I won't get much sympathy in central FL.
