ECU for EK4

[rally-spec]

Today I discovered my ek4 (b16a2) is for some reason running a p73-003 ecu from a b18c, which would possibly explain the late vtec engagement point and bad fuel consumption. From what I understand the stock and proper ecu for b16a2 is p30? I can't find this ecu for sale anywhere, I have a spoon pw0 and stock pw0 ecu from ef9 (jdm b16a), can I use these at all or will it not work with the b16a2 distributor? Does anyone know where I can buy a p30 ecu or what other options do I have?

Thanks

P30 is for an obd1 b16a/2 such as crx delsol and eg6 civic

Ek4 uses p2t stock

Thanks.. I will see if I have any better luck finding p2t

[rally-spec]

Finding lots for sale however there are a few variations, is p2t-003 the right one?

you need one from a EK4 and not a EM1

[rally-spec]

So does the code from EM1 and EK4 ecu's differ so I know which is which?

[ECU-MAN]

By looking at the ECU connectors

You will then need to pair the ECU to the cars immobiliser.

Another option is converting to OBDI and running an ECU that is socketed and a P30 chip

How hard is it to pair the ECU to the immobiliser? Will try to google some of this.. also forgot to mention I found this on my p73 ecu and wondered who ECU-MAN was lol

[rally-spec]

Sorry, cleared now

[rally-spec]

To pair the immobiliser do I just have to swap the immobiliser chips between the two ECU's? Seems the easiest option

[ECU-MAN]

That will work

Immobiliser chip may not even be in the P73-003 - I believe that's a JDM ECU which never came factory fitted with an immobiliser

gotta open it up and see - i'm more interested in knowing whats been done to the ecu ECU-MAN
