Instant power with easy plug & play installation

Ready to take your BMW N20 turbo to the next level? How about up to 50hp to the wheels (65hp crank) on a completely stock car or up to 100hp to the wheels (120hp crank) on a fully modified car? The JB4 features a simple plug and play installation harness for easy installation and includes many features not found on any other tune. Including the ability to enable/disable the tuning from the drivers seat, gear dependent boost control to help with traction, E85 compatibility, built in diagnostic code reading/deleting, expanded engine safety systems, free firmware updates, in dash boost gauge, the ability to control the exhaust flapper using your BC button, and much more.

The JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. For more advanced enthusiasts the BMS DATA or JB4 Mobile cable allows you to connect a laptop or smartphone for additional gauges, data logging, and free firmware updates as we add new features and maps. Also note some F10 and X chassis models require a JB4 mobile adapter or BMS data cable to select options bit#1 to enable the in-dash controls for those models. 

The JB4 is a full plug and play device that installs and removes in minutes at home without special tools and unlike flash maps that permanently write over your DME with the JB4 your DME is never aware it's running more than the factory power levels. And when you're ready to change things up the JB4 is not VIN locked and can be moved to your next vehicle or resold.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.

NOTES: The X1 & Z4 N20 JB4 is very different than the F series N20 JB4. They use special firmware (with full dash control) and have a different CAN mounting location. The firmware is below and labeled for the X1/Z4 series N20. X1 N20 JB4 Install video & details here.

What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.

Very informative and well written. Check out Phrasing.
Format: Kindle
Very informative and well written. I especially like the concept of Phrasing as an aid to meditating on the Word. I don't know Greek and got a lot of value out of it.

accessible Greek for all
Format: Paperback
I got this book for my wife, who is a complete Greek novice. She enjoys it. And it is accessible for her. The book is divided into three sections, where each section gives an increasingly in depth summary of nt Greek. This is a great idea; if you only want to know the basics, do section 1. If you want to know a little more, perhaps do section 2 as well. Section 3 starts to get into the basics that you would hit in a first year text book. This is not a replacement for a first year textbook; this is for someone who doesn't want to commit to a first year textbook. For a extra fee, you can order helpful videos done by the author himself.

VERY GOOD FOR ITS PURPOSE, SOME RESERVATIONS
Format: Paperback
To same space, WM= William Mounce. BBG=Basic Biblical Greek Grammar. This is an expanded edition of the earlier book of the same name. One will recognize many elements of the author's BBG, but this is more of "how to use Greek for exegesis" so it doesn't have a lot of paradigms etc. WM even puts in the "professor" character from the BBG 3rd ed. He has chapters on word studies, translations, textual criticism, advice on how to use commentaries, etc. It's written at an elementary level so it's an excellent guide for someone just wanting to understand more deeply the scriptures, or to check the accuracy of translations. If one wants to go more in depth, he/she can consult the intermediate grammars like Gerald L. Stevens or Wallace (that one is really detailed!). WM divides the book into sections of increasing depth - Fundamental Greek, Church G., & Functional G. He deals with verbal aspect in several places. He says tenses do have the time element in the indicative mood, but it's second to aspect. Outside the indicative, only aspect is a factor. The 3 are UNDEFINED, CONTINUOUS, and (traditional perfect) complete w/ continuing results. Whether the traditional perf/pluperfect is THE meaning of the tense, or an aktionsart, I will leave to the reader. Sometimes these 2 tenses represent a state. The traditional perfect is there much of the time, determined by the meaning of the verb and context. One should look at how the verbs are actually used (sometimes it's really hard to tell why the perfect was used). Perhaps the old proverb applies to Greek i.e. "the only hard and fast rule, is that there are NO hard and fast rules". The book is helpful for students of the word. One can learn the plan of salvation from good translations, but knowledge of the Greek can answer questions, like the seeming contradiction between (ROM 3:23 & 1 JOHN 1:08,10) with (1 JOHN 3:06,09). Or the question of why Jesus told Thomas to touch Him, but said to Mary "touch Me not" in (JOHN 20:17). Understanding the (normally) continuous/repeated of action of the present tense can answer these questions. I believe the book has a few flaws (thus 4 stars). I think WM gets some things wrong, like when he says a commentator should never say something in the Bible is clear or obvious. One might say this about figurative language - like REVELATION, but if the Bible isn't clear about say, what one must do to go to Heaven, then what's the point? Also WM says on pg 126 (2nd "dot") a student can't "argue" with a commentator or a translator - he/she doesn't know enough Greek. One doesn't have to be a scholar to be able to see when someone is putting in his/her own theology (at least there are enough clear passages in the Bible that one shouldn't have to). The great scholar A.T. Robertson mentions this on pg 389 of his "big book" - there comes a point when grammar stops and theology takes over. Even WM says there're commentaries he doesn't recommend. I recommend the book. As to the few problems, always remember what Douglas K. Stuart said in his book on commentaries "just because one is a PHD, doesn't NECESSARLY mean that he/she is right and you're wrong". Always let the Bible speak for itself.

Greek for the Rest of Us
Format: Paperback
I wish I had had this book when I first started New Testament Greek back many years ago. (I'm sure my grades would have been better, and my understanding much better.) I got this book to brush up on my Greek and it has helped a great deal.
