I have dont a couple of minor mods recently and now my engine
splutters at higher boost pressures of 15psi.
I wired in the 4.7v zener diode mod ... part no (Zener 1W 4V7
1N4732/BZX85C4V7) it is 1 or 1.3 watt part. Is this the right
component?
I wired the zener from signal BLUE/BLACK (L-B 3) to ground BROWN (BR
1) with the band facing the signal wire.
I next turned up the boost on my turbosmart pneamatic boost
controller to 15psi.
Now when you drive the car it splutters and coughs once it gets to
15psi ... up until usually 14 psi it is ok. Its not like what fuel
cut used to be like but it aint good.
I just wanted to make sure that the fuel cut mod I did was done
correctly.
So what does everyone think .. mabey the air fuel ratios are messed
up now at higher boost (leaning out) and I should wait until I get
aftermarket engine management before I run higher boost or that fuel
ratios should still be reasonable seeing its only a few extra psi and
my fuel cut mod is not working properly.
