Okay I got the car ready to start it up but I can't get any spark when my Aem EMS is plugged in. When I plug in my stock Ecu I get spark.

Any suggestions on what settings need to be changed or looked at to fix this problem.
Thanks

 

Sounds like your ignition driver circuit is blown. IIRC this was a common problem with 1012s.

AEM are very good about repairs though. My fuel pump driver circuit blew and AEM repaired and returned it for $50.

 

double check that it is setup for a 4 cyc, reload the base map from aem,

 

Basically the car has been sitting for over a year and were trying to start her up on the new setup with my old base map.

I have a 1052U model #
We reloaded my original map the one I had before we made changes to it for the injectors and 3.5bar map sensor.

^^I will double check that it's setup for a 4cy. If not I will reload the base map from aem.

Man I hope the Aem is okay, Just another thing to fix.

any other possibilities?

 

Under the parameters list do you get "stat sync" on while cranking?

 

^^I will have to check that tomorrow.

I'll let you guys know what I come up with, thanks

 

Hey, I have the exact same problem with my 1052. Pls let me know what the solution is. Thanks

 

What city are you guys located in? My shops located in torrance and im AEM EMS certified. If You want it looked at PM me and ill try and help you out.

 

check stat sync and battery voltage if your under i think like 11 volts the car wont stat sync. Also check your crank sensor.

 

the common cause for this issue is low battery.

I had a lot of problems similar to this and they drove me close to insanity at the time. I think I blew 1 of my Bosch fuel pump because of this.

The good new is that they were all fixed with a new battery or full recharge.


The AEM requires a lot of power compare to other ECU's. My other car has an ECU that only requires a minimum of 7 volts and the software will actually warn you prior to shut down.
