Hi, Terry,

I have X6M E71 with Hybrid F-series turbos + exhaust manifold + *********.
I use BEF + JB4 + WMI
We already tuned properly map6, but still some questions with WMI, how to control flow, and what is the difference in map6/7 in meth control.
I didnt find any explanation on forum.
Thanks in advance

WMI flows on maps 6 and 7. But, map7 uses the additive to raise the boost target as a function of flow.

Do you have a tune as well? I'm always going back and forth between 1 & 6 while averaging 18-21psi.

You should try map 1 to see where it gets you, then try map 6 (if you're getting 10 on map 4, then add 8psi on map 6) and see if you can reach 18 or so.

Bear with my crappy cropping collage, I've yet to edit the steering wheel controls to see which ones apply to the S63 version and/or which actually work.

Do you have BCM?

You can get the low boost error code from targeting higher boost and as the JB4 keeps trying to trick the ECU, it will eventually trigger enough of a difference, that the ECU starts to think you have a boost leak. I was having the same issue.

AFR vs AFR2 are the two banks. Each AFR sensor. Post a log, I didn't see any issue with mine on the AFR

AFR stuck at 20:1 is an o2 sensor or related fault. Read faults and address as needed.

It looks like your AFR and trims are not picking up or something. Strange, maybe check your wiring or sensor? I don't know enough about the JB4 to diagnose that.

I went through and checked all of the vacuum lines and ended up replacing most of them and confirmed that I had no other boost leaks. That didn't actually solve my issue, but maybe it helped. I pulled back my boost target some and that has solved it for now, since I'm on Map 7, I am only targeting a 5psi increase right now, much more than that and I start to get the boost error code 30FF. Since I don't have the BCM, i'm going to oder that soon and see if I can turn up the boost more.

For you, I'd be sure to check all of those vacuum lines, I know at least one of mine was leaking a little. I'd do a 1-2 to clear the engine codes and try Map 1 again.

Varies greatly. Evaluate your own factory boost in your datalogs looking at DME BT.

Yesterday I install my JB4+BCM.
I have made few test runs with race logic today.
I have in the bottom ESS stage II tune.

I got my best times with MAP II. Much better than ESS stage II.

I'm very happy with it and next step would be Dyno test with
- Map 1.
- Map.2
- Map 3.
Last week I dynoed the car with the ESS stag2 and with Bosch dyno it showed 636 hp. / 850 Nm. Im sure its going to show more with JB4.
I have
- ESS II tune
- Down ***** with race cats
- F10 M5 headers.
- (Stage 2 turbos waiting in the box).

My best 1/4 mile for now is 12,08 / 118,12 mph so I'm pretty sure Im under 12 sek with JB4.

Can someone tell my which map is more powerful. MAP 1. or MAP 2 ?
At my car it seems be MAP 2.
And once again. What is the factory boost at X6M? Its seems that nobody know

Cant do that because I have already the ESS stage 2 tune in the bottom. ( its higher boost)
Therefore I ask .

Okay, thank you for that info.
At BMW X6M and X5M specs its read there should be 17.4 Psi.
But now we know.

It's neither, factory max psi is 17.4. bmw does not list a minimum, but I have log(stock) in the winter time with da around 33 and it was around 11psi. So like terry said it depends on several factors. Example: same truck today with da 1400 degrees would log 14psi to make the same power. So it varies its not 10psi and its not 17.4 but it is somewhere inbetween

Default Pure Turbos - 08-08-2017, 10:59 AM

Late to this party....
Some of you may know me as I've been around on other forums, but new to this one.

I have;
-PURE TURBO (stage 2) installed
-AA ********* installed
-RK intakes installed
-AA (stage 2+) for Pure Turbos Flash installed









Truck feels stronger, but I feel like there should be even more power, given the massive successes with Stage 2 Pure Turbos on other platforms. Unfortunately, there is NO AWD DYNO AVAILABLE to me at this point, so I have no idea where I'm at (still looking)... I do have 3 slips from a test & tune day at the local drag strip with *** and Tune only (This was BEFORE the stage 3 Pure Turbo and RK intake install)

Active has since done some minor tweaking to their/my tune files based on data logging (3 back to back pulls on the street through the end of third gear). The adjustments helped, but the end result wasn't anything dramatic like some of the responses in this thread that have suggested "stacking" the JB4 on a base tune.

...So I ordered a JB4 through a buddy's shop several months ago and (twice) they have received different modules, neither of which will fit my truck's connectors... THEN, I find out that the JB4 for our trucks (e70 X5M) has been DISCONTINUED altogether and is no longer supported!?!

WHAT AM I TO DO NOW!?!

Terry.

I test few times with Map 6. It don’t shift any higher than gear 3??

Is the map for pump gas or E30 if I want to test drive with 22 psi?

Default ESS II - 08-08-2017, 12:07 PM

Hello.

Here is my dyno chart ( Bosch) low read dyno. Sorry no Torque curve.
I have in the bottom ESS stage II tune. And this chart is what ESS software gave.
My mods is.
- ESS II
- Down pipe with 200 Cel race cats
- F10 M5 headers.

Now I have install JB4+BCM and I have use race logic to test if the JB4 maps are stronger and map 1 is stronger than ESS II. Notably stronger. From 0-62mph 7% stronger times.

Next step. Dynoed JB4 MAP 1 and MAP 3. with E30 gas.

Here is the dyno chart 476 kW / 636 hp at the crank.
