For Sale JB4 + Usb
I'm looking to remove my JB4 within a few days and was seeing if anyone is interested in it. It comes with the USB, and is the plug and play. Also has the firmware from a few months ago. I'm trying to sell it locally, but if no one bites, I'm willing to ship for free. $400 and it's yours. Last edited by Chicks-Love-Bimmers; 10-20-2011 at 12:41 PM.. |

Now that I've had the chance to try out the JB4 and Procede V5, I must say the gains gained from both are very similar. With the JB4, the power feels a little more raw and you definitely feel it when you push against the throttle. With the Procede, the power feels more consistent and smoother. It feels like stock, but you have more power. The thing I miss about the JB4 is the steering wheel control menu, it's easier to use in my opinion. I can just leave it in map 0 and go the dealership and they will never say a thing about it. You can do the same with the Procede, but the command menu is through the cruise control stick. If anyone bumps it, they may be able to tell you have a tune installed. Both can read and delete codes, both have autotuning (though Procede's is superior) and there's more user parameters you can control with the Procede. To be honest you can't go wrong with either tunes, if you're FBO, Procede may be the better tune however. If you're stock or just have one or two mods then JB4 will be fine.
