im trying to see if i can use my razo shift light to TURN ON my vtec. i posted somthing beofe but still not clear on what to do.
I would buy a VAFC or a MSD activated switch but dont have the funds right now.

i have a non-vtec ecu ( will it work? )+

some one please help.

 

umm no and no

 

if you couldnt work it out from the info in your last post, then we aint gonna be able to help you much more.

PLUS, if you do manage to get it to engage, your fuel maps will be WAYYYYYY off and your car will run like crap.

can you get a VTEC ecu??????

t..

PS this is not a flame

 

yes...i have a vtec ecu...but i tried to convert to obd1 but didnt work...nothing matced u and no maual could help... so what the hell else can i do?? i am sooo miseable w/o my car. sorry for being a pester

 

i understand your pain, it took me three weeks of trying different things to get VTEC to work on my 1983 car...

persistance,

i'd say your best apprach will be to get the VTEC ECU that suits your car, if this is to expensive, search hte internet for details on OBD conversions...

a quick fix will be hte shift light to relay to VTEC solenoid as described, you should be able to manage this...

the temple of VTEC link in hte last post should have been the most indepth assistance for you there...

waht is the VTEC ECU you have? cant you fit it into you car???

maybe if you posted a question about htat? (maybe you already have...)

give us some more info and let it flow from there...

i have neer worked on 91 civic, but on my 92 (obd1) I am doing vtec head swap from a 96 (obd2). you will need a vtec ecu and a harness to convert it to your harness, or you can buy complete new replacement harnesses to replace yours (better for complete engine swap). the vtec switches work, but for better performance the VAFC is the way to go. you will have the correct air feul mixture with this.
here's a couple sites that answered most of my questions on converting to vtec:

http://crx.honda-perf.org/articles/m...torprimer.html
http://crx.honda-perf.org/articles/m...oreminime.html

one more thing... whatever your first though on the cost of this swap was; double it- everything adds up fast. but you can get VAFC's on ebay for less than 300 if you look hard. good luck

 

i tried doing the obd1 coversion ( that is the ecu i have) but i messed my wiring all up. now im stuck... i know i can use the 91 si ecu and dissy but dont know what pins to use for the vtec... man im an idiot
