I assume you've resolved this? I had similar higher boost problems with my JB4 for a while that turned out to be misfires which was resolved by going 2-step colder plugs gapped @ .20.

Why not 4psi on 93?

NGK says one step for every 75-100hp. Stage 1 is only like 50hp so I'd stick with one step colder vs two...unless you plan on going JB4 and/or a stage 2 flash. Terry had the best online prices for plugs, so I got them through BMS' website.

I've gotten the 2F24 whenever I've tried pushing anything past 21psi on my JB4. 21 or less and it's fine. I'm looking into checking my boost pressure sensors and swapping in new coils next to see if that helps.

Car: 2011 550i Manual
Default 09-12-2017, 07:08 AM

New 550i owner here. I looked for a long time as a friend has the 8 speed auto with x drive but I wanted a 6 speed manual and they’re not very common. This also ensured I couldn’t opt for a TU version as the stick was discontinued by then. Considered a M5 too but manuals are hard to find there also. I’ve had it about a month and it now sits on stands awaiting new rims and some other bits.

I bought a BMS stage 1 tuner to start as was recommended and will put that on once the other items are done. Reading this thread and other forum posts I still have a couple of questions.

1) My stage 1 kit is according to Ando at 4psi over stock just like the stage 1 on the JB4 set-up but here I see it used to be 2.25psi and then raised to 3psi. Is that correct or is it now 4psi as Ando stated?

2) Am I able to alter settings in the stage 1 at all? What can I do with the cable or is that only applicable to the JB4?

3) Being that I live in the Reno, NV area where we start at around 4,000ft one would presume there is a significant efficiency loss with the intercoolers and the system is already working harder to compensate for the natural barometric pressure loss at altitude so what are people running without issues in similar elevations or mountain areas?

4) Given the issues with direct injection and carbon build up I am thinking a catch can setup would be a good start but also considering methanol injection as the cleaning effect would be a side benefit along with the ability to run more boost. Anyone here running meth in a N63 and how much boost are you safely running? Anyone have experience with the cleaning effect on these engines?

Thanks in advance for any advice.

N63 is 3psi over stock on the stage 1 and on the S63 it's 4psi overstock

the older N63 units (2.25psi) are adjustable and the newer units with the Rev3 V2 board (3psi) are non adjustable

Hey, sorry for the long time between posts on this thread... missed it somehow.

I am now running jb4 beta with bcm, M5 plugs at .022.

I don't have any issues until I run boost over 22 psi. At this level I am running out of fuel so I have to crank up FOL to 90 to keep AFR down. This causes a fuel pressure error (shows as drivetrain malfunction) but this error does not impact performance at all.

I don't run meth so to get octane I have to run a custom fuel and NOS.

I am working on adding meth now to augment fuel and eliminate the custom fuel.

When you go over 22psi, what codes do you get? I'll get an overboost code (2F24) anytime I go over 21psi. I'd assume the JB4 would have kicked me into map 4 if I was running lean but to be honest, I didn't watch my AFR. I'm running 80 FOL so I'll try 90 and see what happens. I'm finishing up my meth install within the next few days and I've got new coils coming in the mail.

I get error 120708 when running at 90 fol. I don't get any description of the error. I assume it's a fuel pressure or voltage error because I don't get the error if I reduce fol to 75. I have run boost up to 24 with the usual spikes to 28 on throttle lift without errors.

Problem is that my afr is too high at these boost levels, so I need to move to meth.

I would not assume the JB4 would change maps on lean condition unless you have set that.

I don't but I watch it carefully and make decisions on fuelling based on this.

I tried 90 FOL and stayed at 21psi across the board on map 6...reduced power at partial throttle but no issues at WOT, no codes. I don't know WTF to think anymore, especially since you're pushing 24-28 w/o issues.

AFAIK it's set like that ny default...Terry?

My X5M doesn't seem to like an E30 mix and my FSB is bad so I haven't been able to finish my meth install. It never ends.

The runs where I am over 22 psi are all with custom fuel. Added toluene, and some methanol typically around 5% max and a little water. Any more than 5% alcohol causes super lean conditions that the ecu doesn't like. The small amount of alcohol and water makes a big difference but, No way can I run anything close to an E30 at these boost levels.

I will also add a Can of NOS as insurance. Makes for an expensive tank of fuel... and a hassle. I have been doing it to see how far I can push the stock turbos. I have not confirmed that it is 24 psi due to the ecu topping out on the fuel additive.

There is a lean run safety system active on it at around 15:1.

Quick question. I just got the stage 1 for my 2014 550i GT n63tu. I'm a little confused by the default setting. According to the install guide at http://www.burgertuning.com/instruct...e1_install.pdf

The default setting should be 11 o'clock. When I cracked my open, they are set to 3 o'clock



I'm not crazy right? This would be *really* bad to just install in my stock 2014 550i GT? I do have 93 octane here in TX, but no meth or ******* *** or race mufflers.

Also, I dunno what's up with the swear filter, but it censors all sorts of stuff that it shouldn't and I haven't found a way to disable it on this forum yet.
