What ECU for SR20DE

I have put SR20DET in my S15 but I have kept the SR20DE wiring loom and ECU.

The engine is from a S14a 200SX but I have put on the distributor from the DE engine so it would run with the current loom. I went to put on a Apexi Power FC but as this was deigned to be used with CAS and will not work with the dizzy.

What I want to know is what ECU upgrade would be best for the SR20DE to cope with the extra fuelling and airflow?

Just also to say im looking at the Emanage Ultimate as this has settings for the SR20DE and SR20DET.

no one?

I believe you said you coulnt go to the DET Harness so I think your best bet would to be to get a Power FC designed for the DE motor... Since you have to use a Distributer then you'll have to use a N/A ECU (it sounds like the Power FC you got is from a DET?)


I would think that the Power FC from a N/A S15 would be best since thats the harness you have.

Either that or you could go to a standalone and rig up your own ignition system :dunno:

I can not find a power FC for the DE, dont think they do one.

Piggy-backing the OEM ECU will be the most cost effective then. its not the best solution, but it will get the job done.

but if you have the time / money theres always the full standalone
