#104674, "so what would you do?"


          

well as some of you may or may not know im in need of a new fmu,the thing is before i get a new 12-1 fmu I happen to have some 310cc injectors so i was thinkin about installing those with a 6-1 fmu and kinda lower pressures,But the thing is is that with the 12-1 fmu/255lph fuel pump/safc2 controller/wideband 02 and stocker injectors i was running a air fuel ratio of around 10.8 and 11.5 so should i just get another 12-1 fmu and keep my setup??? or should I install the 30lb injectors with a 6-1 or so fmu and start the tuning process over.The reason im askin is because i have a feeling the high fuel pressures pre maturley killed my old 12-1 fmu so i was thinkin lower pressure and bigger injectors,Anyway what would you do???

To run larger injectors you need to lower the fuel pressure. You have no way of lowering your using a FMU. You MAY be able to pull enough fuel with the SAFC but I doubt it.

I'd run 10:1, 8:1 at the lowest.

if you've got an SAFC, buy a set of RC 440's and a 3:1 recal disk. They can be made to idle on stock fuel pressures withthe SAFC (at like -48%, LO, 1000RPM emoji)

SFMU is the best way to go. FMU are shitty and do not work as good. Check ebay and you should be able to find one fairly cheap.

you expect to take advise from a $7/hr idiot vortech CSR who knows probably nothing on 2gnt's? IMO, if you get another FMU from them, you're hard headed and wasting your $. Either SFMU, my VROG regulator, or stick w/ what you have. do as you wish
