OK i just installed the dsm injectors into the car last night and it's way too rich at idle so i was wondering which fmu calibration kit to get cause i have a 12:1 i think

or would i be able to get a FPR and just turn down the psi a bit?

i already have the 440s too -50 on my afc so any help would be appreciated

 

DSM 450cc injectors + 12:1 FMU =

That's ALOT of fuel, and i'm willing to bet waaaaay more than you need. Most people who switch to big injectors (440+) remove the FMU altogether. The injectors alone provide a substantial amount of fuel, you won't need to suppliment them with an FMU for a while. Ditch the FMU

EDIT: just for reference sake, I ran 12psi on my D16 with RC 440's and no FMU, and it was still rich even with -38% AFC trim

You want no FMU.

Use a standalone or SAFC to control the fueling.

if you are hurting, try turning your fuel pressure down alot. You will be mad rich.

thanks for all the help i'm gonna take off the fmu and put it to -38 and see how it is there thanx

 

what kind of car do you have? Youre going to need something to control that size injector as the stock ECU is unable to!?!

 

He says he has an afc. Im assuming you got the resistor box too.

 

i have a d16z6 turbo

i don't have the resistor box instead i wired 10ohm 10 watt resistors through each injector

 

and you are going to perform the "AFC hack" so that you can compensate for boost?

 

how much u plan on boosting

 

i want to boost 10 psi i have the greddy turbo kit so i need to un install the black box and i just uninstalled the FMU and i'm still rich at idle so i guess next is the black box

any help is greatly appreciated
