where do i wire the wires in the ECU to the vtec solenoid? i searched for about 30mins, i could only find in the FAQ to wire to a VAFC. what if i get a P72 and plug it in, then how to wire from there>? i also have an obd2a-obd1 jumber harness if need be....

IS IT NECESSARY to wire the knock sensor and secondary intake solenoid in order for VTEC to activate?

i got this, https://honda-tech.com/zerothread?id=1284177

but that only gives me the wire, and the ground ....i heard there was a third involved?

 

using P72 ECU

 

BUMP** just ordered chipped P28 ECU need info on how to wire oil pressure switch and Vtec Solenoid please....

you don't wire the ecu, the ecu is already set up for vtec. you need to run wires from the jumper to the vtec solenoid itself. your going to need the opposite male/female plug for the green plug on the solenoid. hope that helps

i did wire from the jumper harness, but still havind some problems.....

seems to run better on p28 ecu rather than a P75 LOL, it was burning hella oil with a P75 ecu, and ran like **** after about 5KRMP

 

p75 is an LS ecu you dont want that.

 

yea thats all i had and i needed to get to work, so i ran it like sheat for like 2 weeks, before i got a P28, now it runs super smooth....but i got to get the CEL checked out now.....

 

do you know how to check them?

 

yea i gotta do it after work, i went to look at my new 5otrim drag turbo and tial wastegate with downpipe, make sure it was legit ..... took up my lunch time....i reset the ECU though and the light still came back on.... so i gotta check in a lil while...

 

throwing codes 10, 14 and 22

 

got it thanks!
