Hey guys is it wise to keep my fmu after I have done upgrades. this is my setup below

T3/T4 Turbo
FMIC
JGE B18B block 55 psi max
Stock B18C5 ITR head complete
Tial wastegate 10 psi
Magnecor Plug wires
walbro 255 fuel pump
RC 440cc injectors
AEM Tru Boost Gauge
Hondata S300 (On Order)
Crane cams ingnition system

I have a few more stuff to add such as a new radiator and slim fans. This build has taken me a while and still can't see the end but it will be worth it

 

for one thing, you need bigger injectors than that. For another thing, I'd never use an FMU to start with.

 

No, you shouldn't need an FMU with larger-than-stock injectors and a good EMS(in this case Hondata).

 

from what i understand fmu's were never designed for hondas but rather v8's. ditch it and go with something else.

it was originally designed from what i remember for supplimenting the fueling needs on the vortech systems on the stangs. i am pretty sure there have been rising rate regs before.

to the op, with your list of mods, depending on the power level, the 440's may or may not be enough, but with the s300 you no longer have a need for the fmu.

Exactly what he said. Oh and as for the FMU...throw that worthless thing in the trash. You wont ever need it again

 

Or you could sell it on ebay! There is alot of people that still use them......... Until injector failure
