I've got a 2001 Prelude SH with a JRSC on it. I tried to install larger injectors(440cc) and control them with a VAFC. For some reason, whether the VAFC was wired before or after JRs FMU, the VAFC would not adjust the fuel curve at all. I put the old injectors back in and removed the VAFC because the car ran really bad with the oversized injectors and no way to modify the fuel curve. Does anybody know how to get the VAFC to work with JRs FMU?

Do you have a fuel pressure gauge, if so what are your pressures...?

The JR FMU really shots the pressure up, so thats probably why the V-AFC is really not helping with the injector pulse width. Might have to go with a CarTech FMU or something like that, and a adjustable fuel pressure regulator. It will allow you to take better control of the pressures. Along with a fuel pressure guage, to set it correctly...

However the CarTech is a little flackly tho... hehehehe

No fuel pressure gauge.
I've got the rising rate regulator(I think it's adjustable) and fuel pump that came with the SC kit.

Edit: Apparently my tech talk is very poor. When I searced for the Cartech FMU all I found was a regulator, I thought the FMU was the "black box".
