im using the stock p28 ecu

 

Youre either going to have to get someone that speaks japanese and get the ecu from a civic ferio with d15b and a wiring diagram on how to wire both solenoids. or wire them all together and hook them up to your vtec wiring that should already be in your engine bay. Since your car was vtec to begin with.

 

im gonna get da ecu chipped n tuned 2run the p08 maps

 

ok, and how do you wire both solenoids? Youre going to need a ferio ecu pinout at least. Its gotta be different pins to control both solenoids or something

 

Not all d15bs were 3 stage, some were single like the z6. Which one do you have. Hope its not the 3 stage, that sucker only made 100hp, although it did get great mileage.

 

Huh? More like 128 hp

Youre right there is two d15bs both were not made in the US. One was single vtec solenoid. The other was 3 stage. Both of them had around 130 hp

 

The one youre talking about is the d15z1 out of the 92-95 civic vx. That made 90 hp and it was vtec-e.

 

Got me there.. I didnt even pay attention. Saw d15 and vtec and immediately thought of that measly little bastard.

 

well he can look on the side for any signs of 2 solenoids.
hopefully its not the economy vtec.

 

hope this help u bro. honestly i should do the same thing when reciving my jdm D15B LOL.
LMk how it works out for u i'll be in the same boat SOOOON..
