Hi
Just got my Stack AFR installed
Nice bit of kit, easy to install and fits nicely next to the SPA gauges
Im running closed loop from MSD on a T3 peaking at 2 bar
on idle I have 14,7 (sometimes it takes a little while to settle though)
on wot my AFR shows....10
, to me that is a "bit" rich - correct?
on cruise it fluctuates from 14,5 to 15,2 - very rapidly.
I would have thought that on cruise it should just settle close to 14,7 like it does when idling.
my CO screw on the ECU is centralized - so thinking of adjusting it to go a little leaner, and aim for about 11,5 AFR on WOT.
what do you think?
thanks
