View Full Version : Fuel Cut Defence not working

06-10-2004, 12:33 AM
I have version 1.3 with a 3" MAF and the fuel cut defence dip sitch does nothing for my fuel cut. Any suggestions?

Mods are:
1990 ECU
Walbro 255HP
AFPR @39psi (I have tried higher so I can defer the fuel cut with marginal results)
big16G at about 19psi
94 octane pump gas

Fuel cut is usually MAF overrun. Lean it out a little and see what it does for you.

Fuel cut and MAF overrun are two entirely different and unrelated problems.

Don't bother with that switch. It is a signal cap, which basically just won't let the output go higher then XXXX Hz. I think it's around 2700, but I don't remember for sure.

You should be able to tune fuel cut out with those injectors, although at 19 psi manye not.

Are you still on the stock SMIC? If so, you'll probably be faster with a little less boost.
