here it is again....http://216.242.145.16/products/product.phtml?p=32

do not lock this because the topic was not discussed in the last post about this....it was mentioned, then everyone started arguing about who invented the vortech fmu...i posted this so that it would be discussed because there are more and more boosted d17s popping up....and more discussion can take place....the other was posted 6months ago...there have been many more boosted d17s since then....

thanks

^^^ agreed.......don't lock this one like the last one.

Anywayz.......you can adjust the ratio on these or what? Therefore you would need to have it on the dyno each time you adjusted the ratio for the fuel curve........am i right?

that is what i understand from the website....

Yeah, you need to dyno tune it. I guess alot of traditional FMU's make you run very rich in the midrange before the injectors are at their 100% duty cycle in order for there to be enough fuel on the top end. This DFMU makes an in-line pump act as a FPR. The DFMU regulates the speed at which the in-line pump works. It has 5 different programmable points so you can lean out that rich midrange without leaning out the top end also. I've read a little on it and it looks really easy to use. I think it wouldn't be too hard to get it to where your car would safely run, and then take it to a dyno to have them fine tune it.

Could use it in conjunction with the datalogger opto_isolator found. I'd rather convert to return tho.

yeah, i am in the process of getting my stuff to convert to return fuel...i have already ordered my safc2 for minimal tuning, and my aeromotive fpr....i am working with someone on getting some stainless lines, and modding my fuel rail...

i just wanted to show others what is out there....noticed it on aeromotives website and thought someone might be interested....just more stuff developing for us

All Im gonna say is...its a very good product.

And yes....you will need to dyno tune this sucker. If you just wanna slap a kit on, drive and guess settings....this is not for u. This is for people who believe in and can afford tuning.

what would be the advantages in using this? instead of converting to a return system and using another FMU? convenience?

If anyone wants to take the time to read how it works its quite simple - it controls an INLINE fuel pump throughout your RPM band. It increases fuel pump pressure per the settings through the RPM band. It is a digital representation of SF's fuel setup....

Is it cool? Yes. Would I run it? No. You still are dealing with running higher than stock pressure through your lines and injectors. Fuel pressures can get pretty damn high when boost gets up there....I wouldn't want one of my lines blowing because of this......

So use some braided ss fuel lines. From what I understand, you have to plumb in a bypass around the in-line fuel pump anyway, so why not.

how much does it cost??

^^ Retails for about $400-$500

And it's actually a pretty reliable system. Doesn't work like the typical FMU's and it's less likely to "crap out" on you. I know of plenty of people using this w/out any issues whatsoever. I don't think anyone here is gonna be running 20psi any time soon either.

You guys can still convert to a return system. It's still a viable solution that alot of people are using on their cars...including the EP3's and DC5's. But seriously...DIS's and Returnless Fuel Systems are becoming more and more common. Technology is catching up too. And there are plenty of people w/EP3's and DC5's using this type of fuel management as well. This system in combination w/alc. inj (which is becoming more and more common in the newer tech. cars) can prove to yield very, very good results.

There are just so many ways to handle fuel management that it's hard to decide. And to be quite frank, our cars are so relatively new that there's not enough info out there to point blank without a doubt state which system is better, or will yield more power, etc. etc. It's a matter of test and tune at this point. A matter of preference really. And there are still other roads to explore.
