Is anyone here using a ls or non-vtec ecu to run a vtec setup? I currently have a ls swap but going to build a ls/vtec setup during the winter break. I'm going to use a vafc for tuning. Would the only difference be timing? I could use the vafc to control the fuel and the vtec x-over. What are the stock timing maps like for the ls ecu and the b16 ecu?

 

The VAFC won't be able to activate vtec will it?

 

yes, it will be able to.

 

Oh, I did not know this.

In that case I think you are on the right track.

 

still gonna have a 6800 rev limiter...vafc's can't change that

 

You can get chipped P28's for practically nothing these days.

 

i remember somebody postin up on how to turn a non vtec ecu into a vtec ecu....you have to change a few things but it shouldnt be to difficult.. and instead of the vafc i would almost just get a good chipped ecu...

 

I'm going to run a 75shot, and most chips advance the timing. I've heard of someone that was able to convert a non-vtec OBD ecu into a vtec one. That might be a good option.
