fjo injector driver

nce · Post by **nce** » Wed Mar 18, 2009 7:30 pm

I switched from using a resistor box to an fjo injector driver, and my afr's went way rich, is this something normal because of the opening faster. Ive triple checked my wiring and nothing else with the car has changed. any input would be much appreciated thanks

battery offsets will be considerably different. correct guys?

I was thinking that also, so should i leave the multiplier and offsets the same and adjust the batt offsets? I lowered the injector offset alot and it was still wayyyyyyy too rich, and here i was trying to get precision 1000's to idle nicely without being rich

my assumption is battery offsets and your fuyel mapping will change slightly.... probably not too much overall... but that driver definitely changes the way the injectors work.

Battery Offsetts Yes.

it is amazing the difference in using a true peak and hold driver over a resistor box , throttle response has increased big time nice clean idle . I ended up having to change the batt offsets alot but it worked out great thank you for the replys

If you dont mind me asking how much was it and where did you get it from.

Its the new version way less wires I got it from xenocron for $150
