I'm going at the track next week, now I got some problem with Vtec controller, (Msd rpm switch setup). The damn problem here is that I don't have any money to replace the rpm switch. So I have Heard about peoples plugging Vtec Solenoïd to a toggle switch, anybody got this setup, I already got a Shift **** with a toggle on it, so I plan to add a nother switch in serie for security reason ( don't want to hit the button accidently when not enough oil pressure). Then simply run 12 Volt to the solenoid with the Green/yellow wire. But do I have to pass through a relai?? will I just have to hold on the toggle, or do I have to release it when shifting???
any help greatly appreciated!!
thank you !!
see ya

 

come on!!! anybody can just tell me if the vtec solenoïd working on 12 volts???

 

That's a very ghetto setup and I don't advise it.

 

i would highly suggest against it but yes the solenoid runs on a steady 12 volts.
just a warning. the battery probably wont give steady power. hence a fuse.

edit: if you do, do this. make sure you plug it into the correct plug. not the oil pressure conncetor.

speaking from personal experience.. i used this setup for a few months before swapping.. it DOES activate it, just dont abuse it and it can be rewarding.. i had a vtec controller, but i sold it.. so instead i hooked up a switch to activate the solenoid.. you can splice the power wire from the ecu (not sure what color it is) this uses a 12v current.. one wire from the ecu.. to the toggle switch.. then another wire straight to the solenoid (yellow/ green wire) try this at your own risk.

 

Yep i Know it's Getto, but what is so dangerous about it???? I mean, if the Vtec is activated over 5 000 rpm I'm am not supposed to get some problem nope???

 

well.. its really not all that dangerous.. the only problem i had was a blown ECU fuse.. i activated vtec with the switch, and boom.. car died.. find my ecu fuse blown. the only reason for this was because of the half *** wiring job i did.. i had no problems with the solenoid.. i sometimes tried activating it at 4000 and it worked fine (car went slower though).

 

O.K, so if i take another 12 volts supply in the car, like the wire comming from the lighter plug, I should have no problem at all? do you think it's dangerous for vtec solenoïd, how many Amp should I rate the fuse???
then is there any way I can arm my engine, except for activating with low oil pressure.
