So its basicly like a apex vafc
but it automaticly adjusts the fuel??

Any one with more input?

 

that seems hard to do automatically...

 

Without getting any input from a wideband sensor I don`t know how this should work..

The only thing I can imagine is that this controller has a few basics data programmed which had been set for stock engines...
So if you set vtec lower to, say, 5500rpm that fuel and ignition timing changes also, depending on what the software sais

 

I'm curious as to what they mean by automatic.

It would either have to include a wideband or work off of the factory knock sensor to make adjustments automatically.

 

factory knock sensor = crap

 

Where IS the factory knock sensor ?

 

Underneath the intake manifold.

I think problems with the knock sensor are more program related (i.e. ecu) than the sensor itself. All peizoelectric resistors are pretty much the same.
