720cc on an SAFC2

Brian O Conner · May 14, 2011

Mods dont delete this post. I already searched the forums. I am not totally positive if my ecu is stock or not. I ordered 720cc injectors for my SAFC2 and they say its really hard to tune but is it impossible and can I get my 420a tuned good even thought the injectors are too big also how much is a megasquirt unit? Thanks for everything dsm tuners community and dont get pissed off when replying just want to know if I spent a whole week setting up the fuel and air ratios if I can get this thing well tuned one whole week straight. or am I fubared.

im not really sure if its "impossible" but i would really rather be safe and get the megasquirt that can run them with a very precise tune then try to wing it with that and get fuel-cut or really lean condition while at your target 20psi and mess up you new motor build. u could resell that unit and put it towards the ms. a quality tune is the difference between going fast and going home (after you pick parts of your motor out of the road/track)

I think that the safc2 does not have enough adjustment to choke those bad boys back. Unless you drop you fuel pressure way down as well. Jumping from 190 to 720 is way too much.

I stepped up to 275cc and im sitting at 23% correction at idle.

Also take a look at the 420a engine management section there are a couple of great links like these...
