will it fit? Need advice on aftermarket ECU placement

[johnpinetree]

Hi all, I've been cranking on this thing and haven't had time to post in an embarrassing amount of time, BUT, I'm hoping to be able to start the Coyote soon.

I'm going with an AEM Infinity ECU for the Cobra, and it comes* with a wiring harness of it's own in lieu of the Ford powerpack. I first thought I'd have some freedom to route things where I saw fit but now realize things are tight and options slim.

SO! Will this fit?

Second question, has anyone spun the intake around to the passenger side? I haven't figured out if I'm doing the Moroso tank or not... maybe easier just to do a smaller intake and keep it on the driver side? Open to suggestions!



*came... Holley bought them and they are now out of the ECU game. Can't tell you the panic I've had...

I'll offer an opinion: you've got a lot of room on the PS, where the PCM/ECU would normally go. Your DS looks pretty crowded. You mentioned that the harness is a tight fit. Have you tried the ECU elsewhere? I guess that would be the determining factor for me - where everything fits the best. The "usual" location for the Ford PCM is mostly out of the way, but you can still get at the connections. Have you tried it there with the bracket that presumably came with the kit?

The only thing I'll offer regarding your intake is that I wouldn't make it smaller. That could have implications for a whole bunch of things from a tuning and performance perspective.

Yeah unfortunately the wiring harness is dictating that the ECU go as depicted. Noted on the intake, thanks. I think a trip to the autoparts store and staring at options is in my future to try some stuff out there.

How much junk goes around the bracket that the ECU is bumping up? I'm guessing that's for the hood?

I know you probably don't want to hear this but you are aware AEM is out of the ecu business right? Basically anything race winning brands buys goes to hell. Aem, Racepak, Haltech is probably next to fall apart. If you ever have problems you might need something else to run it and where do you mount it?

Regardless, the hood mount overhangs the area your ecu is in. I can take some pictures but I'm out of town right now.

The best approach to determining final fitment is to mock up the location with everything included. You will need to install the aftermarket ECM engine harness, at least well enough to determine placement on the engine. Everything that you expect to place around the ECM location must be included to confirm no interference. There is no substitute to doing the best mock up possible. Only then will you be convinced that the chosen location will work.
Good luck solving your location puzzle.

Be aware of a couple things in working out your location:

1) When starting out with a new stand-alone ECU, there is often a fair amount of troubleshooting requiring access to the plugs into the ECU. You have to think about how accessible are the plugs and the ECU with the body on. It's very easy to be deceived on accessibility when you don't have the body on.

2) There is a fair amount of heat and RFI in the engine compartment. Locating the ECU in the passenger compartment helps to isolate it from these gremlins.

3) When you select a location, wire tie the harness to the frame, then remove the ECU and see how easy it is to access. It's very easy to make the harness too short and too tight, making access almost impossible at a later time. I've learned to loop the harness going to the ECU somewhere remotely so there is about 12" more cable than what would normally be required. Makes it much easier to work on.
