Firstly , sorry for my language, it's on weak level;].

i SWAPed the d15b engine from jdm ek3 into my eg4 and conversed wires to obd1. But when i turned it on - on free gear- it choked and sounds really bad.
but when i drived - it was everythink ok and really fast.

OBD1 can support only 1 vtec , so I resign 1vtec - vtec-e, so make it 16v still, since engine start.

Engine sounds normally when I disconnect the vtecs - then it workin on 12v .

So I think the problem is that engine should work on 12v on free gear.


So do anybody have any idea, how to make 2 vtecs on obd1?
 
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.
 
VAFC or Hondata I think supports it. But yea good point about the 2 vtecs I forgot about that...
I was reading somewhere that somebody had just made the whole car run on 16v constantly and disable vtec-e. Dunno how though...
