at the last mapping we max'd out my injectors
so a new set of 610cc siemens was sorted,
he said when you bung them in you'll probably
have to drop the whole fuel map 20%.
bugger me fitted them tonight and sure enough
20% brought the afr's back to normal, which
was massively rich as soon as i fitted the 610.
installs more confidence in my tuner.
big up NOBLE MOTORSPORT.

Shame its a Vauxhall

if you knew engines the xe is a brilliant
power plant and used massively throughout motorsport.
anyway i'm on here for the performance side of things
not the griffin,blue oval bolloxs.
anything that goes quick rocks my boat

but why on over-run do the injectors not
cut fuel off totally?
i noticed on the live screen that .5milli secs
is still suppling a little fuel with revs up and throttle
closed! why ?

Thats because the ecu is still driving them.

Obviously not configured to cut fuel yet on the overun boundaries.


You probably have a minimum on time set and overun disabled.
