Default any other AEM EMS problems?

- as you can see in my avatar, im about to do a little something that would need (recommended) the AEM EMS...
- the two problems I have found so far (from searching) is: 1) the temp gauge not showing and 2) the idling 'problem' (shows a fix though)
- are there any other problems (AC or anything)?

Idle seems to be ok in my car but one thing it doesn't like is starting from cold when its been left overnight if its colder than usual, any other time it cranks right up first time but its just when it get a little nippy you have to hold the start button for a few sec's longer!!
If I'm honest the cold start could probably be overcome if my tuner was a little better at his job, I had a decel issue a while back when the car kept stalling but that was sorted with a bit of better mapping!

Can't really say I've found anything else up to now(keeping my fingers crossed that I don't).

What I've found, and realize I don't get that cold here, is that if I let it sit with the ignition on and the fuel pump running for a couple extra seconds before I start the car it fires in about 8 cranks If I start the car immediately after turning on the ignition, it takes more cranks. This is on a cold start.

This is usually just the fuel system getting upto the correct pressure(due to the bigger injectors and pump it takes longer), the cold thing shouldn't make that much difference

My cold start sucks when it's colder than 45 degrees. Above that, it starts great. I think if I play with injector timing and cold start enrichments I'll be fine. No problems idling. I have MUCH more tuning to do though.

To set your cel to show you a high temp warning, you need to activate ls10 in the output options

set your coolant to at least (219) or the temp you want it to activate.
set the load to at least -13.90PSig
set the rpm at least 0
set the TPS at least 0.00
set the RdSpeed at less than 200 mph
make sure you activate both check boxes

So far my car starts like stock in cold and warm. The only time I had problems with starts is if I drive down the street and turn off the car, it cranks 3-5 time before it starts. That only happen on short drives and my car idles like stock as well too.
Other than that, I love this system in my car
Also, I plan on heading to UL's shop when I drive it home for the summer for some more tunning.
