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.

Sounds like a good idea for a new option/variable to me. I am in Wisconsin also and kinda admit it sounds pretty stupid to have it plainly run rich regardless if the car is warm or not. Especially with craptastic cars like mine (That die alot)
