VAFC. get the ECU to activate the 2nd solenoid, and get the Apexi VAFC to activate the first. or the IAB VTEC ecu. (p72?). Use the IAB function to control one solenoid and use the VTEC to control the other.

you've got a 3-stage D15B. it has TWO vtec cross-overs. 3-stage VTEC Examine the SOHC VTEC and SOHC VTEC-E implementations. The clever Honda engineers saw that it is a logical step to merge the two implementations into one. This is in essence the 3-stage VTEC implementation. 3-stage VTEC is...

Thanks for the input! my mistake, it has only 2 profiles, but the first is used for 8v/16v operation, and the second is for the "kick in the pants" part. I'm aware of the capabilities of this engine. i'm not sure what transmission exactly it was matched to, but i'm fairly certain it...

Its not often that i don't know exactly what i want or what in my car or what direction i want to take this project. but here i am: stuck! First, i guess some background information would be helpful. I'm swapping a D15B (the OBD2 one with 3 VTEC cam profiles) into my '90 DX. With a little bit...

alright first of all, he's looking at a d15b from a JDM 96-00 civic. the engines themselves are hard to find, but sometimes some dumb importers sell them as d15b non vtec engines because the valve cover has no VTEC anything. anywhere. you need to look for a non-vtec looking engine with 2...

the three stage vtec was a JDM b15b engine in the 96-00 civics. The beauty of these engines is that they can get 55mpg and 130HP. The problem is that they are OBD 2, and finding a way to control the 2nd and 3rd vtec stages is a bitch. not only are the original p2j(not sure) ecus nearly...
