can i run the hack with 270cc rc injectors. I been had them and want to use them till i get more money for bigger one and hondata. Does anyone have setting for this if it can be done I would appreciate it. I have missing link and fmu I know I wont need if i run the hack but what do you think. ON a b18c

thats barely any room to do any adjustments...you might need to still use the FMU with it...

heres what liam gave me

(b - a) / a = c , where a = orginal injector size, b = new injector size, and c = percentage larger.
ie

(450 - 240) / 240 = 0.875, 87% larger

To find value needed for the afc you use the same formula..only swap around the injector sizes..

(240 - 450) / 450 = -0.4666 or -46% (although id add 10% on top of that to keep the honda happy under boost)

thats to get to the stock injector size flow...

Ok my fmu is a 10.1. what do you think. I need help with this im stupid

showtymers619

i say get the stock setting as close as you can with the injectors... then add 5% all around and have the FMU do its work...it also depends how much your gonna boost...

270cc RC injectors would be good for no more than a few pounds of boost using the straight up AFC hack. The cusion those injectors create is much smaller than the 440s.

At 270cc your ecu will compensate for the "would be" extra fuel.
I would recomend running a fmu with the afc, use a 10:1 fmu and the afc to fine tune the fuel curve. Otherwise you can run 2psi or so with the 270cc injectors. 240 is stock so 270's areonly about 15% larger

so how much boost would be alright with the 10.1 fmu and the 270's. i just need it to get me by a couple of days.

i would say that prolly good for 7 psi at the most.... its prolly almost close to 310cc .. but thats pushing the injectors

Without a FMU, you need at least 440-450cc/min injectors to properly run the hack. Since you can't run any bigger than 500 cc/min (SAFC limitation), 440's or 450's are really your only choice.

With a FMU, you can run any dinky little injectors you want.
