You'll have to capture a log of the event and put it in the support section of this forum. I can't quite make out what is happening based on your description. I'm not clear on what you mean by 400 - 500.

Hey man,
It's hard to tell without a log as we'd be guessing and assuming things without one. If you want an accurate answer as to why your car is shaking and rev hunting you'd have to create a thread in the support section and post a log in the csv format.

Yeah dude, I just don't wanna say stuff and it be wrong. But so far it kind of sounds like you have unmeasured air leaking past the maf sensor. Check your charge ***** to ensure they're tight, then check intake clamps.

But as of now nothing is for sure until a log is provided, ensure its a csv and not a data zap if you want input from BMS.

You need to upload the CSV and should really be posting this in the support section

Can i run the e85 map with a stock turbo just a few bolt ons? How much E85 do i have to use? minimum/maximum amount of e85 with that map? If i don't have any e85 will it not run right with the 85 map?

(im running the stock lpfp and hpfp)

Hi Ravs here from SA.

Just installed the PS2, but still running the standard OBDII firmware. Car is PWG F30. Need some help. To run the ISO firmware, do I need to do the diode cut? or just load as is?

N20 TMAP and resistor mod will be done later in the week.

Thanks in advance.

On the PWG board, you have to physically cut the diode, then upload the firmware.

Then set FUB = 4 to use the meth adder since meth will be my primary fuel supplement?

I use 100 octane at the track but at $12 a gallon I don't use any on the street.
I placed my order for the Pure stage 2 today. Can anyone answer this question?

So does this mean no dyno tune necessary?

In what context? Its hard to understand what you're asking exactly, and by dyno tune im going to assume you mean custom ecu tune specific to your car.

In terms of just general tuning with the jb4, it uses the ECU's self adapting feature combined with its fail safes and pretty good boost control to tune the car so you do not have to get a custom tune.

If you run a larger turbo timing is a bit too high and doesnt contribute to making extra power so a custom ecu tune or a resistor mod is a good idea to lower that timing to prevent excess motor wear and tear.

I meant as in after installing the pure stage 2 turbo, do I need to take it to a tuner and let them tune or would my jb4 do the job. I've been contacting a few Bmw tuner and they all said I need to bring it to them for tuning. Even Jesse from pure turbo said that. So I'm tryna figure out if it's true, hell if I could save the extra 600 from not taking to a tuner , that would be awesome

I mean you do have to do some adjusting on the jb4 user adjustment page, take logs and submit them for BMS support to review them. Otherwise you shouldn't need to take it to a specific tuner, those BMW specialists are probably referring to a flash tune. Jesse @ pure probably meant you had to adjust a few things on the jb4 to ensure it runs smoothly.

What adjustments to the JB4 settings did you guys make when running the backend flash? After 4/2, Do we need to zero out Duty Bias like the n54's? AFAIK, AFR bias is unused in n55? What about FOL?

No adjustments are needed but do plan on having to dial in duty bias for the turbo being used. FOL is generally unchanged also.

Terry@BMS is Cobb a must for BEF for n55 or is there another way. What does the n20 t map sensor do? I'm a newbie at this .

The N20 Tmap can read higher pressure than the stock unit. Stock caps out around 21psi whereas the N20 can read to 3.5 bar. You also need a few psi headroom.

For a BEF, as you're an E series, if looking to load a BMS flash then COBB is currently the only way. You do however need a MEVD172 DME and compatable ROM.

There are however rumours that MHD have just hired a new 'flasher' expert.

Hey guys,

i need some help about my M235i with the N55 EWG Engine. I would buy a Stage 1 Turbocharger from Pure. I run the JB4 Map 5 with *******-Pipe, chargepipe and bigger intercooler. Dou you think i have to switch Map 6 or i can use Map 5? I want no E85 Mixture or something.

You can run map 5 no problem. Go with the stage 2 instead of the stage 1 (coming from a stage 1 owner).
