Electronic Fuel Management neccessary?
 

Well, I'm not familiar with electronic fuel management, VAFC,Hondata,Greddy Blue Box, Etc., or anything to do with fuel. But i heard it is needed (electronic fuel management) if i use DSM injectors. But also i heard i can use my stock B16a injectors and use some sort of fuel pressure. To compress more fuel for the engine. Without using Hondata or anything to do with the ECU.

So i was wondering if what i heard was right or not. Also I saw a site ( http://www.cse.uconn.edu/~yelevich/turbo/turbo.html ) that doesn't say anything about Hondata, VAFC,etc....

Can you guys give me more informations... I'm confused of what setup to use. THanks alot!

Can i use this setup instead of electronic fuel management?

Yeah I'm curious too. Us noobs ::)

Re:Electronic Fuel Management neccessary?
 

that set-up uses a fmu, they raise the pressure of fuel going to the injectors depending on how much boost you are running. if you don't have a bigger fuel pump, then it doesnt matter how high they raise the pressure because your pump wont keep up. a fmu/stock injectors set-up isn't recommended for anything more than 8 psi or so

im using an aftermarket ecu.. "megasquirt" this is boost referenced and increased the injector duration as the boost goes up. Also using the vortec fmu.. with a bosch fuel pump.. It might be overkill as im going to run low boost levels, but for $110.00 to build the megasquirt its well worth it, and who knows if i decide to crank the boost im covered. i little overhead is a good idea here as engines are expensive. :o

Re:Electronic Fuel Management neccessary?
 

Do you have any info or a link on the megasquirt system?

Re:Electronic Fuel Management neccessary?
 

For the Megasquirt group purchase system!

To find out some info go to the yahoo group.

Thanks for the info. Looks interesting. 8) To bad I hate wiring. :'(

Re:Electronic Fuel Management neccessary?
 

hey, wildman. I was wondering if you need 450 cc injectors so that will work megasquirt thing will work properly?

Re:Electronic Fuel Management neccessary?
 

And what's the differences between FMU and Apexi AFC/VAFC/SMC/Fields controller?

Re:Electronic Fuel Management neccessary?
 

The Megasquirt is fully programmable.. You enter values into the rom of the pc board.. through a laptop.. you enter things like.. injector flow in cc/hour, # of cylinders, stroke, cubic inches, e.t.c... it measures your water temp, manifold air temp, manifold absolute pressure, ignition events, e.t.c. it uses a ve table to calulate the correct amount of injection duration, it will work with any type of injectors.. Obviously the big ones give you more potential in terms of maximum safe boost pressure. but keep in mind if you boost over 2 bar or 22 psi you need a mod to the megasquirt board/software in regard to the map sensor. its current map sensor and software is limited to 2 bar . others have done the mod. check the yahoo group for details.

one more thing on megasquirt.. Go to the yahoo group and download the megasquirt software.. "free" .. Looking over the screens you will get a good feel for its potential.. It can be adjusted on the fly, and save to rom while driving. this is great for tweaking your system. Building and installing this unit will require alot of reading but I never built a pc board before and mine works perfectly.

Re:Electronic Fuel Management neccessary?
 

That looks like a pretty cool device, although limited on when you can get the thing. Does anyone get a bunch of kits, assemble them and resell them?

I think that Split Second has something similar available to run secondary injectors, in relation to boost.

Re:Electronic Fuel Management neccessary?
 

The group purchase thing is a slow process. However they did several hundred on the last group buy. I have not heard of anyone building them for resale. You might get someone to part with their version 1 system who has just built a version 2. There were a few changes in the hardware / software "non boost map was used, "2 bar map sensor was a mod on version one.. so you would need this mod for turbo.. Many people did the mod to use ver 1 on turbo setups.. Worth a shot.

Re:Electronic Fuel Management neccessary?
 

wow cool stuff.

Re:Electronic Fuel Management neccessary?
 

looks like the device from split second will help out if you wish to keep your stock ecu. and just wish to add more fuel on boost. Some high end aftermarket ecu's have a higher resolution in the ve table "this is best for high end race apps", e.t.c. Megasquirt is more of a middle of the road device "its ve table is limited to 8bit resolution" . You really needs to decide what your goals are before you decide on any of these units.. The engineering of a custom turbo kit requires alot of thought and planning. Dont rush it, dont waste money on stuff you dont need. engine management is the most important part "read all you can" :D
