We're slowly expanding the data pool and collecting data as we go. Next up I'm looking to trade cars with a 2011 for a few days to determine what is different with the MAF startup routines. If anyone knows anyone in socal who wants to drive a 2013 for a couple days have them email me.
For boost monitoring you can also kick boost over to the fuel gauge which will read from 10psi (empty) to 20psi (full) in 1 bar increments. I've added an option to the latest CT firmware to also have an option to show PSI from 10psi to 26psi in the speed for those running higher boost values.
Also for those helping test the JB+ keep in mind for BETA we generally discourage public discussion of BETA products for various reasons. I won't be checking in here often so be sure to continue email correspondence with me.

Either way, keep up the R&D and let's see the JB+ out on the market!

Hi i have the system installed on my MINI aswell, shes a build date 12/2011 MINI Cooper S Coupe. Some mods done are 2.5 exhaust, FMIC, Forge Recirc valve, JCW stage 1 conical intake and lots more overall, Methanol injection is my next step. Attachment 79288 The Yellow line is boost i am peaking at 18psi and it drops a touch as i go through the rpm range. The pull is from 2000 rpm up to 6500 rpm.

The problem with finding testers is finding the people who don't care about modding cars to play with them, I had my car a week before the exhaust and intercooler were swapped in favor of different unit and then it started lol I have had my car apart a half dozen times for various things. Most regular Drivers are not willing to take a leap and test something -pyrrhusmj if you know someone with a CM who's willing point them in the right direction.

As a rotor head first and foremost if it can be messed with I will!!! I explored a ton of stuff with my RX-7's and I found a guy herein TN with a N54 BMW and got to see that JB tuner in action. It's amazing the night and day difference in his BMW and its night and day in my MINI. I'm extremely happy Terry and the guys at BMS are tackling the MINI!

Actually there are probably two willing to take the risk just in my neighborhood.

FWIW....I had a chance to take jomama's R56 for a spin the other day with the JB+...
Overall I was quite impressed, for what is only 15-16psi of boost, it really hauls. Boost comes on smooth and power delivery is pretty seemless. The CAN stuff with the gauges is pretty interesting, never really seen anything like it. I'd prefer to have an actual device that reads out data (like the AP does), rather than relying on the speedo pointer for all your data, but is pretty interesting & cool none the less.
The only thing that kinda leaves me wondering is the fact that you are just essentially fooling the ECU by altering MAF sensor signals, you are relying on the stock ECU mapping to compensate with the increased boost levels. On the dyno Terry posted you can see how lean it runs on the JB runs...leaner than stock up till about 4k. Yes I know its DI, yes I know they can run leaner than typical, and yes I know the ECU's are highly adaptive...but these are things that interested folks should be concerned about, which I noticed not a single person even asked or commented on. Not at all questioning Terry or the product (his product is highly successful and respected in the BMW world)...as I said before, everything I experienced in jomama's car was great, just point out my observations and thoughts.

ThumperMCS, I have talked with Terry about my concern with early lean condition. His response is this is par for the course with Di BMW's. I will take his word for it as the car seems to not detonate and or pull any timing. I am running a small amount of E85 and the car still behaves the same at lower rpm high load situtations which is good. At this point I would not second guess him.

Just in case anyone isn't familiar, Terry's products and customer service are unparalleled in the bmw community. For what you get, BMS prices very fairly and continues to support their products for a long time to come. If they released this for the n14 i would have no qualms dropping my accessport for it. Sure, in some ways a flash could be seen as preferable to piggyback and chris at alta is top notch as well but between the past 2 setups i've run, unichip and accessport, i've grown leary of dropping the coin on something that seems to only be a limited run with no future support.
Terry, if you are reading this i am experimenting with an additional inline pump to run an e85 blend, would love to have you on board with the n14's if it is at all feasible for you guys

yes, he is. it's really tough to see any details on that chart. i can't tell which line is which color on the AFR chart. hopefully it reads as you suggest. =)

The JB+ is working off the factory mapped timing and AFR tables for a given boost level.

Thought i would run the JB at the 3 Oclock position with 25% E85 blend and wow does the cooper rip.. The car also benefits from a ebay step intercooler and a 2.5in CNT exhaust...The factory ecu logic for boost tables in I-2 gear seem to be limited to 14psi which is good as boost builds faster and traction would be a problem without the limitation. So the overall driving behavior has not changed until you get into boost. Third and forth gear pull really hard, I would expect the car to be making at least 240ft tq from 3k to 5k rpm. Btw no issue with KR throughout the rpm including low rpm high load situations. Anyways thought I would share my experience so far with the JB.

18psi under heavy load, big difference right?! Lol
