Ok I need some help, I got a 00 civic si with I/H/E, when i bought it came with a crappy vtec contoller called Precision Vtec Controller. I was plan it to remove it cause I have no need for it? Can you guys tell me the easiest way to remove it? it just started to act up and jump my vtec engagement points around......Id apreciate it thanx!!!!!!!!

 

honestly, no offense, but if you have to ask, you should probably pay a shop to do it. It requires some quality wiring, and knowing how to do it from experience in order to do it properly, or you could cause a lot of damage.

 

I know the basics of wiring, if you can pin point what I have to do I’ll apréciate it

 

not all controllers are wired up the same. You have to find the original installation manual and schematics in order to be able to remove it yourself

 

typically, you need to remove all aftermarket wiring, and look at all the stock wiring colors and reconnect any stock wires that were cut. And it needs to be soldered and well insulated.
If more than one wire has the same color scheme, that's where it gets fun because you'll need to look up wiring diagrams for your car and figure out which wire needs to be reconnected to to which wire.
