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
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
So does the code from EM1 and EK4 ecu's differ so I know which is which?
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 Attachment 27979
Sorry, cleared now
To pair the immobiliser do I just have to swap the immobiliser chips between the two ECU's? Seems the easiest option
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 ;)
