Ok I have a set of 850's I want to install as the Primarys.. I did a search on this but came up empty. In the PFC commander manual on page 26 it tells you how to tell it to run with different size injectors. Is this all I have to do? This is a common swap, so someone should have done this already. According to the manual I just divide 550 (old) by 850(new)=0.647 so I enter 64.7% and delay went from .73 to .77 so I put +0.05ms and thats it right? Or do I have to go through the maps and take out the extra fuel in the maps too based on the greater percentage of flow?
Thanks

 

You will have to make minor mods to the injector orings or the primary rail if you want to do this. See my web page at www.wvinter.net/~flanham/wlanham.
