A friend of mine brought back a HK tuning magazine that has our S2K on the cover and tons of available upgrades specifically for the car -- you won't believe all the good stuffs we are missing.

One thing that really caught my attention was the Apex v-tec controller, which wileecoyote also mentioned in another thread.

It's description translates to something like: extend the limiter to 9300 and lower the vtec engagement rpm from 5850 to 5000.

Do you guys know what are the pro's and con's to lowering the v-tec engagement point?
Sure it will engage sooner, but are there any drawbacks?
What are the hard numbers in gains?

I know u guys post upgrade stuffs extensively, so if this has already been covered I apologize.

Does the mixture adjustment only consider the RPM range you are in when the +/- adjustment is made? That is, are low load (cruise or lift), medium load, high load, ALL richened or leaned?

wilee, when you do, please let us know.

 

<<It had two settings for low throttle position and another setting for big throttle. Two settings are interpolated and you can specified how many percent opening is a low throttle and how many % is a high throttle. >>

Okay, thanks. That still sounds fairly coarse to me though.

Another issue with lowering the VTEC engagement point is that timing is also changed and it can't be changed.

 

I need help I just got the VPEXi V-AFC (V-Tec) controller and don't know how to wire it anyone please help e-mail me....

 

Try to get on to apex web site or get the telephone no of apex usa to get a wiring diagram as the manual I got had no wiring diagram for the new S-2000.
My tuner got a diagram from fax but I can't get hold of it.
