JB1 firmware update?
1 Attachment(s)
I'm an early adopter with the JB1 for N20/N26 + USB cable. I used to have it on my 2013 F30 (EWG), and I loved it - it was hands down the best accessory I've ever purchased (My original review)

I've switched it to a 2015 F10 with what seems to be the same engine, and the JB1 is not working (CEL) :(:brokenheart:

Is it possible to update the FW to support the new LCI (?) ECU, or are there any tips / tricks I'm missing?

Thanks folks

Hi, sounds like you have an old G1 Stage1 board. Those are not compatible with the current JB4 interface and there is no user adjustment in them. You'll need to replace it for a current Stage1 control board.
