this might be a stupid question, because i haven't seen one negative post (besides loss of OBD2) about the AEM EMS 1052 with an S2k, but i was just wondering if anyone had any problems with this unit?

 

factory water temp gauge doesn't work and that's about it IMO.

 

Unless you use Modifry's ECT:

There were some units that had problems with their firmware and could not see one of the coils. It required a reflash from AEM to fix it.

 

Don't really think this has to be a 1052 specific issue, but I have the 1052U and the connector for the wideband O2 going into the box is bad. Not to the extent that it doesn't work, but its loose or something. It hasn't given me a problem for a while ( :knocksonwood: ) but before it used to stop working every few miles of driving. By stop working I mean that it would get "disconnected" eventhough the connector was perfectly in place and everything looked good. I'd then have to stick my hand all the way back to where the box is in the foot well and mess around with the wires until it started working again.

The other problem I've had, which is a bit more serious, and again Im not sure if it can be blamed on the 1052 specific EMS is the car just not responding to throttle input. This has happened to me 3 times now. I'll be driving and I'll go to step on the gas but NOTHING happens. I can keep my foot planted, or pump the pedal but nothing will happen. And then suddenly a few moments later it'll pick up on the input and start working again. Scared the hell out of me 2 times cuz I was getting on the gas for a highway pull and nothing happened, and then suddenly it started pulling like crazy.... NOT good at all if I were to be on road with any curves taking them at any speed...

 

hmmmm.... interesting, has anyone else had captkirk's problem? what would cause such a problem? maybe the MAP sensor or TPS

 

weird....its not like its a electrical contact, its still a mechanical connection between the gas pedal and the throttle body, if the engine is running and the throttle body opens it should have done something.. bucked, hesitated.. something. im interested in hearing more about this

 

I think you've got a cursed unit. Mine has none of those problems at all.

 

Oh yea def. Let me just clarify that I'm not saying that you will have my problems by any means. I just wanted to respond with the problems I had with the EMS...cuz...well that was the point of this thread

I honestly have heard a bunch of bad stuff about the AEM EMS...but bottom line is its the best cost effective option we have. Unless you want to spend more money on a different system like the Motec or the HKS the AEM would be your best bet. And then the other major problem is finding someone that could tune those systems for you...

So even after having problems with my EMS and hearing about other stuff, I still end up saying that the AEM EMS is the best option we have

 

thanks for replying guys!!!

that's true, your engine should have done something, if it wasn't getting the proper amount of fuel it would have atleast stalled out. Have u checked ur throttle cable? Maybe it was just hesitating really badly. Have you checked your plugs or done the map sensor whack? Checked for boost leaks?

EXACTLY!!! you got it, this is exactly why i started this thread, because I gather from the majority of posts on this board that the AEM EMS is definetly one of the smarter routes to take if not THE smartest route to take. BUT, not many ppl mention some of the smaller problems or annoyances they may have had or experienced with the unit, and what they have done to relieve such issues.


what bad stuff have you heard?


oh yeah one more thing. Captkirk if you ever find out what exactly was causing those problems i would definetly like to hear how u resolved them.
