Setting injector constant on C950...
I know, stupid question, but I was looking through the manual that comes w/ it and I don't see where it talks about it. Thanks.

You gotta be kidding me? No one knows how to set the constant for what inj. they're running?

It's been a little over a year since I had a C950, but at least at that time they didn't use an injector constant. It was all controlled thru the numbers/counts you put into the fuel map.

Yep, Vern is right on. There is no setting for "injector constant". Changing the numbers in the main fuel map adjusts for different injector sizes. If you're tuned for a certain injector size and you change injectors, you need to retune your map for the new injectors. I guess as a ballpark for going from 30lb to 24lb injectors you can increase the whole map by 20%, so to go from 24lb to 30lb I would guess that the opposite is true (decrease by 20%) but that's just a ballpark, you still really have to re-tune the map for different size injectors.
