I have a turbo 600whp flex fuel s2000. I'm about to buy a used 335i 6 speed. I'm a huge gear head I do all the work on my cars my self including clutch job and even building my own engines. but I'm new to the bmw world. Please educate me on some things.

1. What the hell does fbo stand for. I see it everywhere on this forums and I still can't figue it out.

2 dme? I'm guessing This is the ecu. Why do you call it a dme and what does that stand for.

3. I find this crazy but after all the reading I been doing here am I right that you guys don't actually Dyno tune your cars. Your just run after market piggy back ecus like the jb4 and proceed and just run pre made maps and these thing auto tune themselves? Is that even safe?

4. I want to run a flex fuel setup like I have on my s2000. With my s2000 you just buy a $60 ethanol sensor and install it inline to the fuel return and run 1 wire to the ems. Get tune on 91 octane then e85. The ecu will blend the maps. And boost, timing and fuel trims are all automatically adjusted to how ever much ethonolsensor you have in the tank

How Iis this done and can it be done on the 335? Should I get the jb4 or proceed v5 for this? I have also read that these cars can't run straight e85 for some reason and muse runs e60-e70 or lower. Is this true and why is this? Especially when I see you guys run the walbro 450 pump. That pump is good for over 700whp on e85 in my s2000.

5 I have read that you guys don't have to swap injectors when going for more power. Why is that?

[idratherbesurfing]

Fbo. full bolt on.

And yes we dyno cars hahah. Mine is fbo on 93. 406Whp 446ftq

As for the flex fuel. A company FUEL IT is currently finishing ethonal sensor kit for ours cars

Also we can run straight e85. But you need port injection kit on top of our stock direct injection. Our stock high pressure fuel pumps cant keep up with straight e85 alone



I came to the 335 after two STIs. Last one was a 11 second 1/4mile car. What youll notice with this platform (n54 motor) the price to power ratio is amazing, i spent about 2500 bucks and gained well over 100whp. On the subarus. 2500 bucks gets you nothing lol. Its take 15 grand to get 500whp. Im happy with my choice coming over here. Look foward to see what you do!

What is a port injection kit?

Also if I swap out the low pressure fuel pump to a walbro e85 450 how much e85 can I run? Do I have to switch maps when I do this or will the jb4 or proceed detect the high concentration of ethonol and automatically up the boost and timing?

[N111CUK]

also proceed is not as current and updated as JB4. Vishnu has dropped off the radar
we tend to have a piggy and a flash together. JB4 G5 has great features and a flash dials the tune in.
welcome to the platform.

I'll be rebuilding my 335i e92 with RBTurbo JB4 G5 FBO with Meth. no e85 for me in the UK

also a manual can hold more power but the auto box is sweet and shifts fast

[oilphase]

Hi Riceball welcome to n54 world

FBO mean Full Bolts On which they are DCI (duel air intake filters), c@tless DP, intercooler low pressure fuel pump (LPFP) and the list keep growing hahaha. for the DME is another word for ECU, its mean Digital Motor Electronics (DME). For tuning you have options piggy back, piggy back with ECU flash, flash only. cheapest and easiest way is JB4 thats why its so popular.

personally i never used ethanol before as its not available in my area but i heard fuel-it is developing such thing for our cars.

[///Mposter]

Jb4 has an auto tune map 5 that can adjust to fuel, air temp, etc, so you can set it and forget it. Or it sounds like you like to tinker so there is a custom map you can change parameters with a laptop and USB cable.
The LPFP in this platform is a bit different than the S2000 as in the pressure used about 42psi where as the 335i uses about 72psi to feed the HPFP which then turns it to 1500psi-over 2000psi .
Injectors are capable of a lot over stock but are limited as to how fast they can open at high horsepower and high RPM .
You will also see what some people call Lean condition with direct injection on this platform . Read up on it as you might get scared at first.
Anyway...welcome.

[LaCross]

This is the only platform where you can

A: Produce 650whp with hybrid turbos and have no extra turbo lag
B. Produce 829whp with a big turbo on a completely stock, unopened block

Its a secondary fuel system. Use the search bar on this forum youll find good info. Better then i can explain. There are quite a few BMW forums and I find this one to be the most informative for me so you should have no problem finding info on here

Come to the dark side!
I will admit that S2000's are quick, I've been played with quite a few times by one in my neighborhood.
You will not regret the switch though.
What are the specs on the 335i you're looking at? (year, mileage, options, etc..)

[csu87]

2. Dme is your fueling, boost, some other key engine functions. Different from the ecu
http://www.bmw.com/com/en/insights/t...ectronics.html

3. Actually, a lot of guys have custom dyno tunes, but the majority have a jb4 piggyback with a backend flash. Works better than it sounds, and 90% of the time, all you will need.

4. The n54 engine is capable of ethanol blends without a flex fuel sensor. The n55, you have to hook a couple wires up from the jb4to run ethanol.

Map5 on the jb4 will auto tune based on the fueling you're using up to about e40. After that, you need to stack the jb4 with a flash. Once you get the low pressure fuel pump upgraded, e60-e70 is useable and some guys can go up to e85 with the hpfp. Unfortunately, not many options Once your hpfp gets maxed other than overdriving the pump by Vargas or port injection or very shortly, throttle body injection.

5. Injectors can flow a ton. More than your hpfp can.

ummm... 'A' above is not true in my opinion. You will have more lag with 650whp hybrid turbos. You have some logs to prove otherwise? Stock turbos will hit 15psi during spool up at 2300rpm, the largest stock frame hybrid turbos that make that kind of power will hit it by 3300-3400rpm, RBs hit 15psi at 3000-3100rpm.

B is wrong as well. Plenty of other platforms that can hit over 800 at the wheels on a completely stock motor.

Agreed, a junkyard LQ4 with low levels of boost can do this for next to nothing.

[Mike@N54Tuning.com]

I think your questions got answered pretty much above. Best thing to do is plan what goals you want for the car and work backwards. Are you going to do hybrid Turbos? Stock Turbos? Single Turbo? I think you need to answer that first and then decide on the mods you need to support that decision.

1. What the hell does fbo stand for. I see it everywhere on this forums and I still can't figue it out.

FBO usually stands for tune, downpipes, charge pipe and intercooler

2 dme? I'm guessing This is the ecu. Why do you call it a dme and what does that stand for.

You bring up 2 separate points.
Lots of guys dyno their car, if you were here 3-4 years ago you would see that 90% of the people did it. Now that it has been done to death, everyone already knows the power they are getting based on their mods.

When you pick the right tune, you can datalog different parameters in your car and see how it is reacting to the extra power. This way you can always make sure if the map you are using is safe.

4. I want to run a flex fuel setup like I have on my s2000. With my s2000 you just buy a $60 ethanol sensor and install it inline to the fuel return and run 1 wire to the ems. Get tune on 91 octane then e85. The ecu will blend the maps. And boost, timing and fuel trims are all automatically adjusted to how ever much ethonolsensor you have in the tank

Is this true and why is this? Especially when I see you guys run the walbro 450 pump. That pump is good for over 700whp on e85 in my s2000.

If you are keeping your mix at E30, no extra mod is needed. The ECU + tune will do all the extra work for you.
If you need more Ethanol, you need to upgrade your LPFP. Stage 2 fuel it is the most popular choice.

You keep mentioning Procede and i am assuming this is because of all the threads you have been reading. I salute you for doing the extra work and trying to learn about this car as much as possible but you might want to double check the dates of these threads. Procede has been non-existent for the last year in the BMW world.
At one point it was the best tune for the N54, now it is slowly getting outdated.

5 I have read that you guys don't have to swap injectors when going for more power. Why is that?[/QUOTE]

OEM ones are good enough for most power application.

my 6466 can hit 27psi by 4000, the new RB evos spool as fast as stock with at or over 700whp.

[n54gte]

Lol a walbro 450 is not supporting 700 on e85. If youre not going to atleast a 6466 kit, 335i will be tame compared to a light s2k with 600

agree, I have stage 3 kit with stage 2 PI with my 6466

You have logs to post and prove when your turbo hits 15psi during spool up and also the EVO turbos? In God I trust, all others bring data

Edit: I have logs to post and substantiate my claims above about spool for each turbo variations. I have yet to see a large single turbo log hit 27psi by 4000rpm, amazing if yours can. Even the hybrid turbo record by ghost hit 27psi by 4500rpm. Also Fastgti customers brand new record setting dyno with 6466 with the VM kit hits 15psi at 3900rpm and 27 psi at about 4800rpm, is that the same kit you run and same turbo?

[Riceball777]

So the proceed tune is not worth buying any more? I'm better off with the jb4? The reason I bring up the proceed is because they have a flex fuel kit. Is the jb4 compatable with a flex fuel sensor?

very soon it will be.

Right now though, running either Map 5 on the JB4 for blends under e40 works. It will adapt to what fuel you are using so no need for a sensor.

If you run higher blends, going with a backend e85 flash and map 7 seems to do a pretty good job of adjusting for the higher e blends. Ive gone from e60 to e70 to e75 to e85 without having to adjust anything. the JB4 adjust accordingly in my experiences.
