im looking to do b16 turbo with a walbro 255,rc injectors.i know that tuning is key.i live in utica ny i dont believe there any tuning places around.how can i set up the car so little tuning is possible?So is it worth it to do turbo without a tune will it be major losses?

sohc_turd

It will be a total loss without a tune. although i don't condone it, get a base map if you have to.

lucidvtec

don't do it
...tow it to a tuner
it's not worth the risk

no tune+boost = KABOOOOOM

You can get an fmu for now..

groovytunes is a hondata tuner in syracuse.

y8-turbo

i ran my y8 turbo for 1 year on 10 psi and fmu, and it ran perfectly fine, now i have neptune and, its got way more *****, but as long as you dont go nuts on boost you should be ok, oh and by the way dont buy a cheap fmu... my engine has a active knock sensor, maybe thats why it lasted that long but if i had to do it again, i would just get some good fuel management from the get go...
good luck with you build

if you are OBD-1 I can send you a basemap to run until you get it tuned.

lol...the end, no explanation needed

I ran an fmu, stock injectors, 255 intank fuel pump, missing link for about 2 years without one single problem.

The setup was daily driven, saw the strip quite a few times, and was also used in numerous dyno testing (which included 30+ dyno pulls in one day).

AND i got 280miles to a full tank of gas. All with no REAL tune.

The engine never let go, i only took it out to replace it with a built b18c that i built on the side.

To answer the original question... yes you can use the FMU/missing link/fuel pump setup. Just dont boost past 7psi if you want it to last.

vtec.dc2

if you run external wastegate, remove wastegate spring and you won't see any boost.. you can still run on high pressure fuel pump like 255lbs hp intank fuel pump, injectors aren't hard to install, even if you're obd2, you can make obd2 injectors fit into obd1 clips this way everything will be plug-n-play once you get to the tuner.

i was gonna do obd-1.im sorry ive done research and stil are un sure about this. what is this combo FMU/missing link/fuel pump setup? and what are basemaps. im not lookn to go past 8 psi anyway. but someone said there is hondata tuner in syracuse? thats only an hour away but how much does that cost for hondata equipment?

714phil

rising rate Fuel Management Unit= FMU- Raises the rate of fuel pressure per pound of boost.. use in conjunction with either 255 intank or inline high pressure fuel pump... you will want a 12:1 ratio FMU (12psi of fuel pressure for every 1psi of boost).

Missing link=boost bypass for the MAP sensor so that the sensor does not read boost. (if the stock ecu reads boost, it will throw a Check Engine Light and go into Limp mode)

With this setup, you use stock injectors and factory ECU.

In my opinion, if you are not going past 7-8psi, this setup can not be beat.

FMU- $120
Fuel pump- $90-110
Missing link $50

thank you alot,the fmu adjust itself?

i believe the FMU comes with a fixed rate..........just wat i have heard.........

bumop for a good topic because i was wondering the same thing

Like STD ONE mentioned the FMU raises fuel pressure based on the type of disk it has. For example with a 12:1 disk, the fuel pressure is raised 12 psi for every pound of boost you run. Your stock fuel pressure is 45 psi (or somewhere around there. At 7 psi and a 12:1 FMU that's 12x7 = 84 psi of fuel pressure...add that to your stock fuel pressure of 45 psi and your fuel system will be at 129 psi of fuel pressure at 7 psi.

That's how you're able to get more fuel out of stock 240cc injectors with an FMU. With a 12:1 FMU at 7 psi, your stock 240cc injectors will flow the same amount as a set of 400cc injectors. The problem with FMU's is fuel delivery wont be the same for different setups. Turbo setups that push less air will need less fuel then a turbos that push more air. A smaller less efficient turbo would probably run richer then a bigger more efficient turbo.

whats a good fmu? and since im looking to run 8psi whats a good setting 12:1?

I think someone else will be able to explain this better, but I absolutly think this would be a bad idea. You can only raise pressure on injectors so much before it becomes detrimental. Its been a while since I've researched FMU's so I can't remember the exact reasons why its bad.....but bad stuck in my head

But I think the best bet would be a modified ECU, and some bigger injectors. Also you can probably dig up SAFC settings that poeple have tried while using bigger injectors. If you were willing to buy a wideband o2 sensor, like the AEM UEGO or PLX wideband, you could probably use a SAFC and street tune yourself and get a pretty descent map going.

Part of the reason is in the other part of my post that you quoted, different setups having different fuel requirements. Also IIRC raising fuel pressure with an FMU increases the wear on a fuel system. The fuel injectors lifespan will be shorter and I think after time the high fuel pressure may even affect fuel injector spray pattern.

Bigger injectors and Crome or uberdata would be my suggestion too. spend some time learning how to tune and when the guy is ready he street tune it himself.

You could always install the kit and drive it w/ no boost to the shop.

D-meet07

if you have some 450cc's should the fuel pressure stay at stock which is 38-40 on the b16's?? I too am considering the afc at 8 psi and running a missing link on a street tune.

buy a plx wideband and make sure the fuel is around 11.8 or richer at wide open ...
