engine swap ECU question

[adcadman]

I want to swap a b18c4 into my ej6 preface coupe. when I buy a complete swap it will come with the ECU (P9K, I think). if I use this ECU with my current key I'm going to have immobiliser problems wont I?

I have read up about other people using other ECUs instead of the one that comes with the engine swap. is it possible to use my d16 ECU (P2E, I think) somehow?

ANY info is welcomed as Im a noob

thanks

I can't answer your question on whether the b18c4 has an immobilizer.. My guess is no? Ask the supplier for your new motor if nobody chimes in here.

It does have a dual stage intake manifold so if you're going to keep it that way and not get some sort of single stage manifold, IE type R style, then you'll have to use an ECU that supports it, like the stock ECU for that motor. The P2E will not work.

You can't use the mb6 ecu you need p28 or p30 with or without b18c4 map

The p9k ecu has a immobilizer and it can be demobilized to run your swap, its a fairly easy procedure too.

Get a conversion harness to suit your wiring loom with a p28 or p30 ecu, then you can get the car remapped pretty easily to suit the setup you are running. £100 should get the ecu and harness if you watch on ebay
