ECMlink FIC 750 Global fuel settings

[VisionPaintball]

Im dialing in my injector settings and for my FIC 750's, so far my global is calculated for 673cc's. Is this common?

Why is it calculated for that? Use the built in calculator to set your global %.

in order to bring my afrest. and actual closer in line.
Last time I had the car running, Dacowgod gave me a quick tune and I had FIC 850's and he dialed them in as 700 cc's.

You should set global % once and not touch it. This number shouldn't be used to do any fuel tuning.

You should be adjusting deadtime to get your idle dialed in.

After that, you should be using the MAF Comp sliders or VE values (depending on your setup).

Idle is fine.

I used this guide;
How to Tune a 1G V3 SD ECM LINK with no MAF V1-3

"if the pull was too lean select the AFRatioEst and AEMwb readings to see how farthey were off. If actual is saying about 13s and estimates that you set in theOpenLoopMaxOct table are supposed to be 11.5s you need to change your globalto get these babies to line up. If this is your case (the 13 and 11.5 example above)then you need to increase Global in the Fuel tab (or go in the direction that wouldultimately be 0 Global, IE: richer)"

If you use the calculator and afr's dont line up what do you do?

That is assuming your airflow (VE table) is properly calibrated.
