Pfs Box And Bigger Secondaries
#1
So, from what I understand, it's difficult to upgrade the injectors while utilizing the PFS Purple box. I've been told that it's possible if you upgrade the primaries and secondaries with the same 550/850 ratio. Why is it that you cant just get bored 850's and throw 'em in for a little more juice up top?

Because the stock ECU still believes it has 550cc injectors in the primary. Different sized injectors need different amounts of time for voltage applied. For instance 850cc injectors will need less time to open up for X amount of fuel vs. the smaller 550cc injector.

It basically is an AFC.. The whole reason for this question is that last summer, I was running 15-12-15 on the stockers, and my crappy little Apex'i Turbo timer's AFR display would no longer peg at 10.0:1 - it floated around 11.8-12.2:1. Now, I know they're not accurate at all, but I'm used to seeing that thing peg full rich on boost.
So anyway, I'm thinking that if I should ever require more fuel, I'd likely just run this setup - bored 850's that flow 1000 cc's or something, and pull fuel at the top like was recommended. Although, at this altitude I could probably put 16PSI out of the stockers with an upgraded SMIC.. Hmmm..
