How many?
I was just wondering how many people are running the AEM EMS.... Once my motor has some miles on it I'm gonna swap mine in... I just wish there was crazy good support for the AEM as there is for the MS....

Paul; would you mind asking him for cranking and idle settings?
I really like how smoothly my car runs with it but I have never been able to crank the car up in less than 1.5 secs and neither can I make the idle valve compensate properly when the A/C is on. About the idle valve; it's some weird setting for sure. It will start working properly after the car has been running for more than 10 minutes. I thought it was related to the AEM seeing a specific temp range but now I'm not too sure that's the reason.
Thanks

Lazer is also a AEM EMS user.
There are others here and elsewhere (mainly the aempower forum) who are more of a wizard than me. I would not consider myself a wizard, but thanks Paul.
To the best of my knowledge, the 1.5sec cranking has something to do with the unit itself. It doesn't fire the ignition until a certain # of revolutions, I think it has something to do with the full sequential injection and spart (if you have COPs). I think if you set up a crank wheel with higher resolution it would fire much quicker. Or I could be completely wrong.
I can send you my map...PM me sometime to remind me. I don't have a problem with idle with A/C.
When I drove Artie's car the other week I was very impressed with how quickly it started (like it "should") and how well it idled. I could fix my idle to be as good as his but it doesn't bother me enough to spend the time.

Tim, thanks for that explanation. I'll check on the crank wheel resolution to see if that makes a difference.
I'll send you a pm requesting your map to see about the idle compensation with the A/C.

I am soon to be an AEM EMS user. I have one I just don't have the wiring installed in my mx-3 yet... hopefully in the next few months... i'll have to bug time for more answers once I get closer to finishing touches on the car. maybe i'll just bribe him into coming out and helping on the car

I didn't want to start a thread just for this question and found this quote from Tim and had to ask: would something like this work for cranking? BrooksTuned
I finally decided to spend some time learning about my AEM and trying to set the car to work properly.
I have to say I'm finally pretty content with how it's running but; I want to fix the final "issue" with the car and that's the cranking start settings.

With something like that you'll get Stat Sync'd ON quicker.
The slow part of starting the car with the Miata OEM cam sensor: the pattern is a weird one so it takes few revs until the box recognizes it and the Stat Sync'd turns ON. Once Stat Sync'd is ON the Miata engine starts right away.
With a similar wheel and a single pulse cam sync you can get Stat Sync'd quicker.
But the better part is that you get 6 times the stock resolution (more accurate spark)
I already cut one of the cam sync teeth of my '94 OEM cam sensor and for crank signal I am running an '99 OEM crank wheel. The plan is some day when I have time to cut more teeth into it so it turns into a 12 tooth one

I guess I'll have to start a thread on the subject because I already have some questions based on your answer and what I've read.
