one wire vtec
okay my car did have AC in it and I need to know do I cut the wire from the ecu where the AC clutch pin went and run that to the vtec solenoid or do I have to find the AC clutch pin on the car harness and if so where is it.. the vehicle is a 91 crx dx..
AC clutch pin location would help too.. |
Re: one wire vtec
Your easiest solution would be to find the wire in your engine compartment harness, cut it, and connect it to your vtec solenoid.

Re: one wire vtec
This is a fairly recent development that has been very beneficial to the OBD0 group who do not want to convert up to OBD1 and run something like Uberdata or Crome Engine Management. Basically now you can use the spot on the ECU that was originally designed to activate the A/C clutch relay to activate your VTEC solenoid with a 12 volt charge. Also, you DO NOT need to add any components to the ECU and this is a huge plus.
Two ways to wire it up from here. If your car had A/C and the A/C Clutch Relay (find a wiring diagram for your car) is still intact, take the 12v (+) wire that is activated and run that to the VTEC Solenoid. Viola you are done (besides setting it up in the TurboEdit program). What am I missing? |

FOUND IT !!!!! YEAH
https://www.homemadeturbo.com/forum/...opic=45320.new Do have a question though for anyone running NG60_Splitime.bin did you have to do this... Now, if you were to set your Vtec up in TurboEDIT and run your car, once you hit your enable RPM you would hear your solenoid just click click click click on and off constantly. That is because you have to change some thing with a hex editor. Open your map with your hex editor and change 7FF2 to 15 change 2888 to A3 and change 2882 to 21. Now you have everything setup for Vtec. or have these corrections been made already, so that all I have to do is hookup the relay? |
Re: one wire vtec
i have the same issue man, i connected the vtec solonoid to the wire that is red/blk that is in the cooling fan harness, i believe its the wire for the ac clutch,lol but i am not really sure if my vtec is actually engagin because i have yet to actually test it with a multimeter, but i will tommorrow and see what happens. your not supposed to have to change anything in turbo edit for it to for, he said that the glitch has been fixed.

Re: one wire vtec
yep, tested it today with a multimeter and it energizes that wire to 12 volts right at 4400rpm like i have it set in turbo edit.
