Im kind of being ghetto but, im wiring the iabs of my basically stock gsr (besides i/h/e) up to my vtec sol. wire. this should engage them at the same time right??? i was just wandering what the pros/cons of this would be if anybody has an idea. im doing this because im running a p28 chipped with vtec at 5500. p72 base maps besides.


Im just looking for input thanks.

 

You should wire up a vtex light while you're at it so you know when you're breakin mad heads because you wont be able to hear it over the blaring lil wayne on teh sony.

 

Perfect ...then I'd be cool enough to write "slick" comments on internet chat forums all day.

 

The pro's to doing this? Nothing except maybe cause the sound of the VTEC engagement to be louder.

Your IAB's are tuned to give you more torque throughout the power band. Honda set it to 5800 RPM for a reason. Moving it to 4400 RPM would likely result in less torque between 4400 and 5800 RPM.

 

Well my vtec engages at 5500 so I guess it could even the scale slightly.

 

Im glad you noticed

 

I'm sure you are

 

In some real answer though, the IAB's are sent a constant +12V, and the other wire is a ground signal sent @ whatever RPM from the ECU to complete the circuit. The vtec solenoid on the other hand, is a single wire switched +12v IIRC. So therefor, im not exactly sure how you would wire it.

The IAB's and vtec are seperated for a reason with the stock manifold, and a p72 is programmed to work with them for a reason, because its what works best in stock form. If you're using a stock manifold with IAB's and the motor is stock, your vtec shouldnt be at 5500 to start with. Without the stock GSR manifold and IAB's (such as a aftermarket skunk2 or something) then vtec at 5500 would probably work better since it would then be the same function as a b16/itr without the stock manifold.

 

As I said though, I'm running a chipped p28 (no iab control hardware) so my "solution" is this. Keep in mind a circuit is a circuit in any diection. (12v to ground or vise versa) so I attach a constant ground of. Solenoid to frame or whatever, and apply 12v for as long as vtec is receiving its 12v signal from the ecu. Its obvious Honda did what they did for a reason but what I'm doing is better then running choked at 8g or loosing that low end by running open butterflies. Right? I mean that's my question

 

i'd prefer the open butterflies...

 

Its definetly an option. I mean I'm not worried about the torque honestly I'm running y1 lsd with this thing in a small car. I was just experimenting with both options you know? And wandering what others thought about the whole wiring thing.
