JB4 map for FBO+inlets and stock turbos - N54Tech.com

seroga1986 · **JB4 map for FBO+inlets and stock turbos -** 06-09-2015, 12:14 PM

Terry, n54 inlets are becoming very common now and i see a bunch of newbee guys trying to custom tune on jb4. Maybe make a map that targets say 22-23psi that can be used with FBO plus inlets? I mean i hope these newbees dont break stuff and blame jb4 for it. I mean 30-40whp is alot of gain after inlets and i think it deserves a JB4 map. I think JB4 will stand out even more from others. Just a thought. Thanks.

Are you referring to a boost map? I think the new map 7 (20psi) is what would be considered a FBO + inlet map... Any higher requires the N20 sensor which most people don't have.

I personally run map 7 on stock inlets FBO w/ E60... If people are running inlets and want to be aggressive they can use map 6 and target 22psi or whatever they want.

Yes we'll be incorporating maps in to the JB4 firmware shortly for them. Still in the process of collecting data.

Awesome news! JB4 ftw!!

I have been running map 7 on e60-70 for past year or more on stock inlets. Now that i have inlets i want more boost. And buying a n20 tmap is not a problem for me or most i would think. A beefy all out 23psi map would be beast mode on stockers.

Terry is this in the near future? I am anxious for this to happen from BMS.

prelude2perfect · 06-24-2015, 05:04 PM

The biggest advantage of inlets is being able to run peak boost to redline. I suggest using map 6 like I do until Terry makes inlet specific maps.

lcvette · 06-24-2015, 05:26 PM

Do you guys have some before and after logs with Inlets? Or maybe Dyno numbers? Would like to see what's possible through map6 tuning with the Inlets!

Inlets are great. Turbos spool quicker and hold boost. Definitely worth it, though a pain to install the rear.

seroga1986 · 06-25-2015, 05:02 AM

Holding 21psi midrange all the way to 20 at redline.

Texsquirrel · 07-23-2015, 01:53 PM

Any ETA on this?

nyt · 07-23-2015, 01:59 PM

Not sure what you're waiting for. Map 6 can be set to whatever you want, and you can use the duty bias tuning to keep things smoother and more accurate.

Texsquirrel · 07-23-2015, 02:39 PM

I guess I could modify a map 6, but I'm not certain what to change.
I'm still new at this.
If Terry builds a tested map, that would be easier for me, and probably a lot of other people.
I've been running E50 on map 5.
I filled up with E60 last night and haven't had time to log it yet.
I hope to do that tonight.
I'm planning on installing inlets this weekend, so maybe I'll try map 7 first and then perhaps...

torn08 · 07-23-2015, 03:05 PM

As soon as I fix my misfire. I'll tune and log on 6, then dyno

Spxxx · 07-23-2015, 03:09 PM

Look at map 7 targets... add an equal % to all RPM points until you are happy (23psi). Honestly it's safer buidling your own map 6 than using map 7 as the lack of taper in map 7 concerns me without inlets, targeting 19psi past 6k RPM scares me with stock inlets so I run a custom map 6 hitting 20psi midrange and tapering to 17ish at my shift point

nyt · 07-23-2015, 03:54 PM

Yeah, wait for your inlets to run map 7. I've modified map 6 to be similar with less taper. You can see the targets in the log above. The turbos still seem to run out of breath a bit between 5500-6000 rpm even with the inlets (drops to 18psi), but a huge improvement none the less.

Dirty Dog · 07-23-2015, 04:30 PM

I run map 7 and just add whatever psi on top of that via steering wheel option 9 (meth additive). So use map 7 as a base that runs a peak of 18.5psi then I add 1-1.5psi so target is between 19.5-20psi. Am I the only one that does this?

What is your roundabout base figure on the dyno with your supporting mods? I have very similar mods minus the LPFP (I'm on E30)

Wouldn't you need to run Map 3 then add the meth boost additive on top of that? I've not tried your approach, however if it can add 1-2psi to the boost target all across Map 7 by changing meth setting, I'm very interested.

nyt · 07-23-2015, 06:26 PM

meth additive is ignored in map 7, that only works in map 3.

No. Just like map 6 you can add any amount of boost on top by using the meth adder. Works for me.

Not the way I have my meth setup.

I think you mean that you have meth flowing in map 6, meth additive is refernced only for map 3 boost targeting (if I understand the feature correctly)

No idea, probably somewhere around 450whp 500wtq depending on the day.

seroga1986 · 07-24-2015, 07:50 AM

Smoothed out my duty bias and targeting 24psi across the board pretty much. Hitting 24psi midrange and 20psi near redline on e60 blend. Thing is wicked.

torn08 · 07-24-2015, 09:31 AM

new to map 6, been reading and logging. what did you do to smooth out duty bias?
