1200CC SFI Injectors Offsets

Hey everyone


I am trying to calibrate some SFI 1200CC low impedance injectors with hondaS300 was wondering if someone can shed some light...

They gave me some offsets but when I use them in hondata the AFR is constant 10:1 even if I pull all the fueling from overall and the map its self. When I run the stock dead time in hondata they run alot better just unstable.

This is what they gave me with the injectors .. any help would be appreciated :)

43.5PSI
3 ohm
1200CC
114LB/Hr

10v - 2.55
11v - 2.28
12v - 2.00
13v - 1.79
14v - 1.62
15v - 1.46

Thanks!

Well isn't that interesting...

When I was doing some research I came across this website that shows a bunch of injector offsets. I ended up finding that the paper SmartFireInjectors sent with there set of 1200 is actually a copy off of there website showing RC1200CC injector dead times. Even the other sizes listed on there paper all are copied from RC injector sizes... Well I guess I will try and figure out the dead time the hard way... I wouldn't recommend these injectors to anyone to be honest.

Did u ever. Figure out the dead times. For the rc1200 I'm having the same issue rn
