anyone please help me !!
Is the motor b18c type r or non type r.
From the picture above, no 1 can tell you what ecu it is. On the side of the ecu will have a code on it lyk p72,p28,p06,p08
If the motor is b18c2(vtir) it is common that u cant hear the crossover
does that wiring even look right..? the two blue plugs were just like that i didnt un plug it..
Yes its normal, if u answer some of the question then ppl can help ya out
b18c1 i will check the number soon!
Its P-72 but the two blue plugs are not plugged in.. i can not located anywhere to plug them
they arent meant to be plugged in. you have B18CR ecu. Have you got a check engine light ? (CEL)
use a pin and stick either end inside one of the blue plugs and put ur your to prime and give us the check engine light code. to determine this you must use the CEL Code guide which is in a diy in the forum.
No he doesnt have a B18CR ecu, type r ecu are p73Quote:

It is common that you cant hear the crossover in these motors, you would need aftermarket parts lyk intake\exuast to hear the crossover.
Those 2 plug don't connect to anything
those 2 plugs are service port to check CEL (check engine light)
so dont worry about it
usually if Vtec doesnt cross over it should give you a yellow orange amber engine light
is that coming up?
looks like it has had a VAFC connected up at one stage in the past...
so does that mean i have to hook up a vafc and reset the settings??
no, it means that the wired might not have been reconnected properly after the VAFC was removed. (see the red 'squish' connectors? they are not Honda ones)
the VACF does not effect the ECU settings.
you also seem to have some water damage down there.
OK guys i have found out the problem, the ECU is a auto ecu.
does it have a 4th connector ith pins in it that are not connected ?
sounds like its a OBD1 AT/PGMFI ECU

I have seen these ECU's before
be vary carefull with them as they are wired different to the OBDI standard, they pulse the vtec solenoid as if it was an AT solenoid
