Hey Team,
I wanted to know what everyone uses for their ride... Ive heard there are big arguments for both sides, I want to run a Procharger P-1SC with 2 or 3 core aftercooler. It comes with an FMU but i heard it causes the car to run rich at idle. I want to use 24# injectors with a 255lph pump but is the FMU useable with this. Does anyone know? Just wondering whut everyone here thinks.... experience is the best knowlege.
Thanx

Yes, they will run a bit rich.
My advice is getting a Custom chip or a EECTuner.

FMUs imho are prehistoric tech, they work ok but are by no means the optimal way of increasing fuel delivery.

so the 24# injectors adjustable fuel press. reg. and a custom burned chip? sounds good to me... which companies actually burns to specs? i hear a lot of "custom" but are stock polymer chips... who do i call and say, procharger, 24 injectors, igniton box, etc. and they burn to that specification?
Thanx

Normally to make a custom chip they need to put your car on a dyno and tune it from there. They will make a couple of runs and then make some changes to the chip. They will keep going between the dyno pulls and changing the settings on the chip until they have the best for your car. I have a friend here in Calif. that does this, and is very good at it.

Thats why I wanna be in Calif, sometimes.... cept for that whole emissions thing. Im in FL.... I think somewhere in Daytona has a dyno tune... hell its where Crane Cams is... anyone know where i can find a performance phonebook? lol.

I use an EECTuner programable chip, it rocks, unlimited modifications with using your laptop.

It is not easy though, requires some EEC-working knowledge, but after a year with it i feel very confortable changing calibrations depending on my mods.

The learning curve is a couple of months to get all the basics and some more advanced stuff.

You can change: timing curves, fuel curves, operation at WOT, shiftpoints on AODES, timing advance or retard, disable timing retard during shifts, MAF size, Injector Size, engine size, intake size, EGR on/off, exhaust pulse delay for longtubes, etc.............its is a long list.

I use 42lbs Bosch on my 10lbs Incon Twin Turbo. Stock electronics. Just played with fuel pressures, T\P, timing and such. Ran great until I blew a head gasket. Plus it did the best of 27mpg

I plan on running flow tested 42lbs Lucus @ approx 60 psi when I get the new engine running. It will have 15-20psi boost. 42lbs@ 60psi is good for around 650hp

I may go with an EPIC system. I know someone that can still get me one. Don't know yet. I will see how it runs first

try the vortech super fmu. it allows full controll of fuel pressure at any rpm range, including idle. It can take an oversized injector down just a tad to where one might want it.

The fmu will not make the car run rich at a idle the only time the fmu will work is when you are on boost.and I would not try to run 24# injectors without a fmu.42 are about as small as I would try without a fmu.fmu tend to run rich just off idle and work well from the mid range up.

ditto! 42s NOT an FMU will make you rich at idle. However with 24s you damn sure want an FMU

i'm running an fmu with 24# injectors it's fine at idle a little rich until you get into the midto upper range on my car anyways , so if you want to go with any thing try the super fmu it's adjustable.and you're car will be fine to cruize around town

My initial setup is to run the best injectors for the system:
24# injectors (just in case)
Adjustable Fuel Press. reg.
Procharger P1-SC Super with 3 core after cooler.
(comes with an FMU [should be best to use right?])
and after that i want to get a chip dyno-burned. Anyone know anywhere in FL that does it?

I run 30 pound injectors without the FMU, when it was on the car it ran richer than bill gates,the plugs fouled as soon as the car was started,toss the FMU if bigger than 24lb. injectors,my freinds 92 has the 24lb injectors and FMU,runs great.
