VAFC2 on R18?

sids · 05-01-2007, 11:39 AM

was reading a thread in the technical section and from what I gather, only the vtec engagement point can be changed, no air fuel.

is this pretty much correct?

Pardon me but I beg to differ.... in Singapore, we have tuned FD1 that has the R18 engine block and gains were noticeable... just with AFC alone, we can achieve average around 3 to 6 bhp gains.

I had a VAFCII at my EJ8 (D16Y8 engine)....installed at my R18 without any problems (just get the ECU wiring guide from the tech book at some Honda dealer).

I was able to change ar/fuel ratio and ignition timing, but couldn´t change VTEC engagement....since it works between 1500 and 3500 rpms, and can be engaged at ANY rpm between 1500 and 3500, thats probably why I couldn´t change it.....but the dial changed colors when VTEC was engaged and disengaged.
