how to converte a D15B 2 vtec solenoid to 1 solenoid?

flour

does anyone knows how to or know any site that can inform me on doing a change on my D15B VTI (3 stage vtec) from using 2 solenoids to 1 solenoid?

why would you want to do that? the two solenoids help with the 3 stages Confused

I am looking at options made available to me. i am doing a change from auto to manual and i am having probs getting a p2j-003 ecu. so i did a little research and found out that the p28 can be used but it doesnt support 2 vtec solenoids. my only option is to change to 1 solenoid to use this p28 ecu or continue searching for this p2j-003 ecu.

Sure you wanna do that? Alright, 2 wires go form the ecu to the solenoids, a green with yellow stripe controls the 1st solenoid (12v mode to 16v mode) and a red controls the 2nd solenoid ( mild to wild cam profile) the ecu sends a 12v+ to engage these solenoids, so I guess if you cut the green/yellow wire and connect it to a 12v+ going to the solenoid it'll be engaged all the time. don't just tap in the +, it cant go back to the ecu.

Wham, you like to buy gas or what?

i know this requires alot of gas. but as i said its an option i am exploring. i just need to get my hand on a p2j-03 ecu and done all my worries and headache.
u said you are using the multimatic ecu with the manual gearbox? correct me if i am wrong.

Sky,
you think with the manual ecu it would make a big difference with performance compared to the multimatic ecu?
i am affraid of what problem i might encounter and thats why i am trying to get the correct ecu. do u encounter any speed restrictions where the ecu limits u from building top speed?

the old model single vtec is not also 130hp though?

only the 3 stage d15b is 130hp..it's the most powerful of the d15s (stock)

what yall think?

looks like the single stage and the 3 stage have the same HP to me

Lol de hell?
The other day the 3 stage was 130hp on wiki, and only other D with 130 was the D16A (DOHC non vtec) with more tq than the 3 stage. Someone change that!!
