On protune BEF by PTF or BMS BEF? I can't wait to see results this is why I am waiting to see when I should purchase the other two mods.

Recently I paid PTF for a E30 BEF to run with my jb4. Now that TBI is installed I will start with the BMS N55 big turbo pump gas BEF but on e60.as Steve mentions in his n55 TBI thread, the fuel scalar when using TBI with e50/e60 fuel needs to be set around 1.0 in the flash.(BMS pump gas flash is very close to this) with e30PTF BEF /BMS e85 BEF the scalar is set to 1.2-1.3 which is too high and will cause trims to go negative. I'll post back after I get e60 in there and take some 18+ psi logs

Awwwwwww yeah! Hope it is THE answer to more boost.

I'm getting stoked! I can't wait to hear your feedback soon. Good luck man.

UPDATE
TBI has solved my high boost misfire issues!!! Hell mutha fookin yes!
I am running a pump gas BMS BEF with added torque for the dct plates E60 fuel and TBI. I took about 20 WOT logs this morning at various boost levels. My car would misfire every time on 22+ psi at the top of third or after I shifted to 4th before TBI. This morning I did a handful of 23psi pulls and another handful of 22psi pulls. Not once did it misfire. I did try a 24psi pull but stumbled on a new issue. DCT slipping a little LOL. So I'm leaving my map6 at 22psi 4500-redline. I am going to do more driving and testing but so far not one misfire! Before TBI with my cm10 I would have misfired multiple times by now especially on the 23psi pulls I did this morning. I will post logs later on as I'm going to work on a few things in the flash but overall my car is very happy now, 50mph 3rd gear is blowing the tires away! Such a smooth power delivery with TBI compared to meth yeeeehawwww

This makes me happy to hear that! Now I'm curious to see how the Dyno would look since you're pushing more than 19psi now. Can't wait to see those logs! Congrats on finding the solution for those horrible misfires.

Yeah I don't care much about the dyno lol. For me I do 1/2 mile roll races all I care about is holding higher boost in the taller gears without hitting limp mode or getting misfires after shifts. I was able to push 20-21 psi before on jb4 with lean AFR flash targets 13.1 etc, with AFR down in the low 12's high elevens 19psi was max. Thank Steve for the TBI kit he is the man! He is one of the only properly running e series n55 on high boost around. Now we know why

Sorry I'm newguy I didn't realize my phone was logged in on this account....

[Newguy123]

heres a snapshot of a log i took this morning. gonna add more e85 and have tbi activate sooner my car was just flashed prior to these pulls so avg ign is higher then i like and timing isnt perfect but you get the idea. 22-23 psi and trims are looking decent with NO signs of misfires. i will keep updating this thread with progress and new info as i figure out what works best for me

Gratz Newguy, awesome news! I can't wait to get my PS2 and upgrade from the PS1, but we just got a new house so that won't be any time soon. I will have to live vicariously through you in the mean time!

How is stage 1 vs stock turbo ? More power or same power but all the way till redline ?

A very small gain (probably 10-20hp), but holds power to redline MUCH better which will lead to an even higher peak hp. It still starts to fall off over ~6200, but not nearly as hard. It is the turbo the car should have come with from the factory. At this point I would do the stage 2 hands down. It just wasn't available when I did my stage 1. I have 20k miles on my stage 1 and it is going strong.

So you have Fuel-It TBI + stage 2 LPFP, and JB4 + Cobb protune BEF?

Any codes or warning lights?

That is correct. I recently went back to the BMS back end flash(they post free flashes on n54 tech to support the fuel used and compliment the jb4. Going to have Dzenno make me a flash with the fuel scalars Steve at fuel it posted over there. I have Idrive and I do get the pop up sometimes on the Idrive that says "fuel pump" when I shut the car off. Bc the stg 2 lpfp draws more power then the stock pump the dme will sometimes think there's an issue and pop up on Idrive when I shit the car off. It goes away when the car is started, no codes etc. I have gotten my car to hit limp mode since TBI installed but I think it's because I'm going too rich. Going to have to wait till dzenno gets back so I can have him fix my fuel scalar. The bms pump gas flash gets you close with TBI but it's not perfect.

With Stage 2 and 93 octane... No BEF as I have 2013 135i... FBO what type of power would I expect?? Same with stage 1??
Since I can't BEF is it just worth staying with stage 1?

Stage 2 has bigger wheels and is more efficient, so you will make more power even on 93, but at the expense of a little more turbo lag. I would still go PS2.

How much more lag ? My drving habits are mostly in curvy roads and in the city where i use a lot 1st to 3rd gear. Will the lag be annoying in city driving and is ps2 more for highway racing. Would i be better with ps1 since it provides less lag and seems to be snappier ?

The lag is not much worse than the PS1. If you are over 2500 rpm you will never notice it, but down low it will take a bit longer. You would probably only ever notice if you were an auto, with a manual you would just leave it in a little higher gear. We are talking a small amount of lag too, not like a big turbo on a 4 cylinder.

PS1 was a little snappier at lower RPMs on 91 octane IME; whether or not the same is true on 93 I don't know. If I can ever overcome this misfire issue with my OEM fuel pump on E30 I'll let you know how the PS2 compares with better fuel in the tank. Butt dyno says it is a lot better at low RPMs with E30 than 91, but I'm not gonna put it on the real dyno again until I have the top end sorted out.

With only 91 in the tank how ps2 is feeling compared to ps1 ? Is a really more powerful on pump gas only ?

Of course it is. Not only does it flow more air then a stage 1 with less boost(psi) but it is capable of running more boost on 91 octane then a stage 1 turbo because it's a lot more efficient(less back pressure).so in conclusion a pure stage 1 Dyno vs a pure stage 2 Dyno (same car, same Dyno, same fuel etc) at ANY boost level will make more power then the stage 1. PS2 would also be capable of running more boost then the stage 1 on pump gas due to what I said above.
