Aftermarket ECU Installaion Advice


Kev.O

Recommended Posts

I'm after some advice on the installation side of an aftermarket ECU. I'm getting to the stage of fitting it where the existing one was, however I can't see how I can fit it in the same place with my fields wiring harness and put the plastic kick plate back on (well atleast not neatly). Does anyone have any pictures and/or advice for me please.

My car came with a piggy back ECU and fields harness, the fields harness allowed the piggy back ecu to be situated outside of the ECU kick plate - I just dont think it is possible to fit another ecu under there as there isnt enough room (not if you want the kick plate to seat properly).

I don't suppose anyone has any pictures I could look at please? I also need to work out how to fix the AEM.

 

I put some spongy type material under the ECU and then used the plastic cover to hold it in place, seems to work alright ;)

Here's a picture of the modified kick plate:

Getting the ECU fitted is ok it's getting the fields harness to fit behind there aswell is the hard bit. I take it you need to fold the wires back over onto themselves so that both ends of the harness are in the same place inorder for the loom to connect to it?

What is it snagging on Kev ?

 

I have to fold the fields harness back on itself but it now fowls the plastic kick plate. At the moment I'm using a metal plate to mount the AEM onto as I don't want it 'floating' under the kick plate.

I put some soft material similar to dynamat under mine and left it free and my fields harness isnt doubled over on itself.
