Customer Testimonials

Just installed the jb4 onto my 2011 335is. I was a bit skeptical at first since BMW already had a tune on the 2011 335is. After installing it, I didn't seem to notice a difference, until after the 2nd or 3rd pull, I can feel the actual pull of it, but also a smoother one than the jb3. overall, ecstatic to drive it more tomorrow, did not regret the install, and furthermore, was worth every penny!!!

Can I use the same BMS USB cable with the JB4?
Yes! The USB cable is strongly suggested as many free firmware updates are planned.

JB4 Maps:
Currently the alpha is pretty stripped down and we'll be adding things as we go. Autotuning (both mapping and PID) as currently disabled.

  • Map 0: Stock bypass. This is the only map you may use a BT cable with.
  • Map 1: 13psi (suggested for most stock applications. Conservative mapping.)
  • Map 2: 14.5psi (suggested for bolt on mods with 93 octane. Close to JB3 map 7.)
  • Map 3: Progressive meth (see guide to enable)
  • Map 6: Custom map. Active but be careful with it.
  • Map 7: 16.5psi. A light weight race map.

In addition to our performance mapping the JB4 features several "on the fly" user selectable maps including:

  • 100% stock bypass map
  • 4500rpm rev limited valet mode
  • progressive methanol map
  • race gas map

And unlike other flash and piggyback tunes that charge per the map and lock to your VIN the JB4 is 100% unlocked. Meaning you get access to every new feature we release free of charge and when your lease is up will be able to resell the JB4 without penalty

  BMS JB4 Stage 3 N54
I'm new to the 1 series tuner world. I've had my E82 for over 3 years and the warranty is finally over so I decided to finally upgrade her. Did some research about what the community was using and the goals I had in mind and decided the BMS was the way to go for me. I cannot be happier with my purchase. It's like she's all a whole new machine. Really comes to life and you can finally hear the turbos working! Can finally let her loose. Time for some better rubber for traction now lol. Modbargains was a breeze to navigate with great pricing and fast delivery! I got my tuner in 2 days in excellent condition! Will continue to buy from Modbargains for all my future mod needs!

Took me a while to install it, wasn't a 15 minute install at all (first time getting into the ECU). After all the frustration and reading, figured it out. It's not something you can just go right into and finish quickly. Takes time to install, and need to be careful with all the wiring. But after getting the car to crank on Map 1, I fell in love with the car again. Spools louder, responds better, and is all around a completely different car. And I'm on the conservative map for now! Thanks ModBargains
