We have had about 5 AEM ignitions not work correctly. We suspect its an overheating issue that is causing the cars to stall while crusing. Once you let it cool down it will start backup with no problems. We can also run the adaptor that converts it back to stock ignition with no problems. Possible solution is mount the unit inside the car but that is a pain in the *** and would like to come up with something else. I know there is another thread about this but we have had 2 more fail in the past week. Please post any problems with them in here and I will contact AEM to see what they say.

Also like to add that we are now carrying the XS Engineering Power Pack that we have tested and have not had any issues with.

i've been pioneering the troubleshooting method with the AEM....

mine overheats, pops fuses, etc, i'm on my fourth one from them now.....

i've been telling people for a while not to run them, but they do not listen, it has a lot to do with dwell time, I have figured that much out.

It will NOT work in place of the OEM ignitor, something quirky, it should in theory, work though.

 

Let me know what you findout.

 

well, so far, i found a manager that I dealt with, his name is kirk miller, 310-484-2322 extension 237

he is a lot more helpful than mitch, and some of the other technicians. He overnighted me a brand new one, which we are now figuring out was actually old inventory, but new in the box-nonetheless...

also, if you send your unit back to them, and they claim to repair it, it's bullshit...these units are not repairable, the internals are potted in epoxy, so they can only bench test them (AT ROOM TEMPERATURE) and then send them back with an OK sticker

i'm patient, and I am reasonable, but when you run something in your car that can fail and cripple you at any given point (i.e, interstate) it is potentially lethal and dangerous

couple that knowledge with the fact that AEM is not notifying all of the customers who have some of the original units of the potential failure, and it is a legal nightmare waiting to happen

what happens when someone gets hurt or worse because of this thing? i've had my car towed twice so far because of this unit...

 

Where are you people mounting this thing? I just got mine and am looking to find a solution that would somewhat address the heat issue.

Also, has AEM addressed this at all? What I find interesting is that there is no operating temp rating on the specs of the thing. I would think that due to the nature of it that there is a limit to that, and that they would indicate that to aide in the placement of the thing.

 

i put mine near stock ignitor, and now it's in passenger floorboard

 

Im on my 3rd and it doesnt work either!!!!

can you say MSD

 

mine has cut off once too. the car started right back up (when i was rolling for like 10 seconds in neutral heh)

i have mine mounted on the cross brace in front of the motor. It gets a good amount of airflow, which may or may not help.

So has AEM fixed the overheating issue with the new(er) cdi's?

If it happens again I will call them, moving the unit inside the car doesent sound like a horrible idea. I want to rewire it with a new coil harness anyways

 

Thanks for the heads up guys, I was about to order one. I've been following the earlier thread and the AEM forum thread and now I'm definitely going with the crane/lx92 setup.

The reason you're seeing the failures is because AEM (if they are not owned by Microsoft) is using you SUCKERS for beta testing.

Didn't the same thing happened to the AEM engine management shitbox too?

HKS Twin power over 2 years no problem at all.

 

it's not cool, someone could get hurt

 

Brian, even with it in the cabin now on your car, is it still failing or cutting off?

Tim

 

Yea, HKS is the way to go. I haven't had any problems yet, car runs great!

 

Hey what ecu are you guys running that have had aem ignition failures?

I have Power FC

 

I haven't had a problem with mine yet. It is mounted where the stock cruise was located.

 

Works fine for me!

 

I mounted my AEM on my FMIC.... VERY far away from any engine bay heat. Thing STILL died on me.

I recevied an e-mail from AEM saying they will replace my AEM with a new one....just need the old one back. But in all honesty, and with all the problems I've had ... I'm throwing it in the trash and going with MSD.

 

will they give you a refund?

 

This thread was not going when I bought it (AEM CDI) or I would not have..... Just got my car back on the road this week and of course I drive it 2-3 miles to get gas and it stops on me, let it cool off and made it back home... Today, same thing.... I think I want to return mine for credit towards the HKS... Unless AEM has fixed this problem....

 

Mines placed a good amount of distance and it died on me when i was just driving normal scared the **** out of me.. Wish i would've went with the hks or msd.

 

I am having this same exact problem and I am already running the MSD 6A... maybe it's just a rare case and went bad or something?

 

I bought the AEM unit as well, and have tried 3 mounting places. Where the cruise control use to be, of course that overheated like everyone elses. I also tried next to my radiator so it gets air from the FMIC. relatively cool location until you get stuck in traffic at which point it shuts off. Finally, the third place was under the dash in the cabin, this also ended up crapping out while waiting for a light. I too think I've had enough of this and will just sell it on eBay and grab an HKS. Its odd that most of the other people on the AEM forum with Supra's and whatnot don't seem to have the same problems; surely their cars must get as hot as ours.

You can put the bypass plug in the aem if the car won't start. It's the gray plug with the red wires that came with the aem. It allows the car to go back to stock ingnition.

 

What is the advantage of the hks over the aem other than the overheating problems with the aem???

 

i think it has to do with dwell times of the coils or something
