fmu question

[lowprofile]

so how do the ratios work on fmu's .ive seen 10:1 12:1 and all this other stuff what does it mean

[ChIoVnIdCa]

adds 10 psi of fuel pressure per pound of boost 10:1
adds 12 psi of fuel pressure per pound of boost 12:1


ex with 10:1 at 3 pounds of boost you are at 30 pounds over stock fuel pressure

Real engine management is so cheap why mess around with that.

Then get it tuned

An FMU is no subsitute for an easily tunable and chippable ecu. It will cost you a lot less in the long run, and the car will run 10x better than just throwing more fuel at it with more boost.

hey i tried to go on that site and it requires a password and mine doesnt work. and as far as chiping the computor , im in colorado there is only a few shops out here and they charge out theA$$ for anything computor work. and would cost me over a thousand bucks and they wont do dry chips or just chip the computor with no tune ?? so thats why i was gonna go with the fmu

He was pointing you towards the for sale forum. Read the disclaimer to learn the password and save it for future visits. If you can't find someone to chip yours search the classifieds and buy a chipped ecu or goto sites such as xenocron.com or phearable.net and order one. It only costs about $200 or so. Or if you want something more advanced try Haltech or AEM EMS.

Hondas and FMUs don't go together.

That is like installing Microsoft Office 1990 (yes it did exist) onto a brand new computer equipped with Win7 and trying to run your company with that setup.

1. It is using super old technology that is very inefficient 2. It will be hard to even get it work 3. People will laugh at you.

If your car "cannot get out of its own way" then your engine probably needs a major tune up or a rebuild. Last time i checked, an F22B1 moves an Accord just fine unless you are planning on racing it.

Install your turbo kit, disconnect the charge pipe and drive the car to a reputable tuner. Then connect the charge piping, install your injectors (takes 10min) and have it tuned.

Hell, if you have a day or two of free time you could do some research and learn how to tune it yourself. All the things that are available now make the process pretty straight forward.

It will take more than a day or two to learn how to tune.....

Well I don't think it is that difficult to learn how to tune a basic stock motor turbo setup. You basically only need a wideband and an electronic detonation detector aka "Listen Up". As long as the AFRs are in the 11s-low12s and it's not detonating, it will last

[DRQPQUT]

just get a chipped ecu and chrome ftw

[drummersteve7]

a veteran callin it chrome...wtf? justin get your shit together.

[chessboxer]

chrome supports vtech! crome does not!

[chessboxer]

It will take more than a day or two to learn how to tune.....

This x elenty billion thousand million gazillion trillion.

Find someone in your area that at least is a good street tuner.

Not to be disrespectful, but honestly, with all the tuning software and hardware that is available now, I could teach my mother how to tune an engine and I'm not exaggerating at all.

Installing the hardware = easy, about the same difficulty level as installing aftermarket speakers

Installing the software = clicking "Next" and "Finish"

Creating a basemap for boost = the software does it automatically.

Choosing the right plugs = 2 min of google search.

Datalogging = clicking the Datalog or Connect button.

Tuning the fuel = 20 min of reading the Crome Beginners Guide, about 2 hours of research on how OBDI works, and then it's simply clicking the Up or Down arrow.

Fine tuning the timing, fine tuning the fuel for tip-in, etc = about 5-6 hours of research and then it's a matter or doing a pull, analyzing the log, and doing a few clicks with your mouse.

Done.

Hell if you have some cash left, rent a dyno and finish fine tuning on a dyno

As mentioned above, with all the tools that are available, you get a lot of data to work with. A quality wideband is only ~ 200 now, then egt, det can, super easy datalogging, real time tuning, all the forums online where you can find the answer to virtually any problem you may have... honestly what else do you need? It's not like the OP is trying to achieve 1500hp
