Anyway, We got everything installed for my LS/Vtec setup. It runs, except Vtec will not cross overer. Im running a p28 w/mugen chip. I ran the Vtec solinoid wire to the D6 location on the ECU and the Vtec pressure switch to the A4 location. A CEL came on at about 6000 RPM, we looked it up and it is called "Vtec Spool Solenoid Valve Circut" I chiped the ECU my self, everything went okay, and I installed everything right I think, but there is a possibility I could have done it wrong I guess? After we pulled the code, we switched Vtec solinoids, and still, it did not work.

Any ideas??? I would really like to feel Vtec cross over!

dumbmadtech

did you ground the pressure switch?

tinkerbell

doesnt it ground itself?

glad to hear it's in

did take all weekend?

what code was it?

lelopez

Hmm.....you have them crossed.....the VTEC solenoid goes to A4 and the oil pressure switch goes to D6. BTW, make sure you use a good ground for the VTEC oil pressure switch.

that shoud fix your problem.

Are you positive? The diagram somone posted in one of my other posts says the solenoid goes to D6 and the switch goes to a4. I guess I will switch them and see though.

Yeah, it took all weekend! We did alot more than just slap the head on. We pulled the whole motor, and did a bunch of stuff. I'll post every thing I did later.

here is that pic...

sounds like you did not get very much sleep. when you ran the wires did you mark them so you would not get them crossed. you may have got them correct at the ecu, but did you put the other end of the wires at their intended component.
where did you ground to? is it sufficient?
remember KISS=keep it simple stupid (i am not calling you stupid, that is just how the saying goes)

Trust me, I'm positive.....I just converted my obd0 to obd1 and how i told you is how I wired the car.....no CEL's, no problem with VTEC.

here is the complete ECU pinout for the p28: http://www.hondaswap.com/articles/index.php?id=17

review it and make sure everything is wired correctly....

good luck,

here is another site http://www.hybrid-k.com/tech/5gtech/...html#ECUpinout that says A4-solinoid and D6-oil ressure sensor
i guess whose ever that was above must have got them mixed up
hope that solves you problem infamousrs

As of now, I am positive that the Vtec solenoid is wired to the a4 location, and the Vtec pressure switch is wired to the d6 location. Vtec is now working good. I just need to do some tunning!!!! Other than that, it runs good.

now you can change your sig

man oh man.. glad to hear that the head worked out good for you.. this guy here (infamousRS) bought the b16 head from me.. port polished, 3 angle, milled, itr valves, itr dual springs, itr retainers, complete head(minus itr cams and distrib), a clutchmasters stage 3 clutch.. hehe.. and now hes got the car running! yes! i'm proud of you. now like i told you.. 8.9 or lower only.. thats all i will accept from the beast... if you don't pull those times.. don't talk to me

turbo_ef9

and oh.. stop beating up on the car! you need to break in the head and the clutch still.. head has not been drivin on yet... calm down..

X2BOARD

Yeah, you should really break it in with at least 800-1000 miles of easy driving first.... sucks, but it's better for the motor.

lelopez

Glad to hear to have the VTEC working.......and YES, you will need lots of tunning to get the LS/VTEC to its full potential, but when you do, you'll be smoking people left and right..

B_CRUZ!

so can someone please confirm that the pressure switch is not A4?

oh ****..thanks.
