After a few months of tuning and letting a professional work on it, I gave up on it. Sure there's some good benefits of the AEM EMS, but suddenly drivability became more important to me. I was much happier with the blue emanage+good drivability that when I switched back I upgraded to the newer emanage.

I went ahead and got the MAPECU2. We shall see what the deal is.

Ooo... do tell i am on the fence here, PUSH ME OVER damn it!! lol

Well i went ahead and bit the bullet, just got off the phone with MVP and ordered the MAP ECU-2 should be here by the end of the week. Although i wont be able to use it till i get the rest of my parts lol

I don't understand why the ems gets such bad rep in these boards... I recently switched from a full EMU setup to the ems, and I was able to work out all those issues you speak of. MehlosTT helped me setup the boost comp and inj phasing on my base map (can't thank him enough!) and got the car to start and run pretty good. About a week later I had the vac sections of the fuel map dialed in, all the kinks on the startup and idle tables worked out. My car starts right away(hot or cold), idles like stock and the driveability is great. All of this was done without ever taking the car to a dyno. Just my 2 cents....

After spending the big bucks on the AEM EMS I really tried to get it to work properly as I believe it was the best thing for my car. Tuning fuel/timing is super easy to do, but the rest of the settings require much more work.

A local 3Si'er stopped by for a visit and when he was ready to go home his AEM EMS setup refused to start. After spending several hours trying to get him running again we gave up and I drove him home leaving his car behind. It's unexpected surprises likes this ate away my confidence in trusting the AEM EMS.

Different model 3S year cars seem to have an impact on the AEM EMS. For instance adding 10 degrees more timing at start made the 94 car start sooner, but made no difference to my 93 (we tried hundreds of different combinations to make my car start better with no improvement). Now that I think about it more the 1311 MAF 91-93 MAP that AEM provides should perhaps not include the 93. The 93 shares similar CAS components to the 94+ cars and should really be tweaked accordingly.

Idle was stable on the 94 AEM EMS car but not on the 93 AEM EMS car. We later discovered the 94 car had a defective ISC and thus the AEM EMS couldn't adjust idle on it.

I truely wanted to keep my AEM EMS as I loved the software interface and all but I was beginning to long for good drivability that I used to have with a piggyback.

Maybe you should get going on shipping out parts that have already been paid for by myself and numerous others.
