JB3 1.4 and JB3 Hardware
Hey guys..
There have been a few posts about different "generations" of the JB3 hardware and what is compatible with what, so I thought I would make this thread explaining things a little more as there appears to be some confusion. There are three types of JB3 boards in circulation, Gen-1, Gen-2 and Gen-3, but in terms of software and hardware compatibility we can group Gen-2 and Gen-3 together. Gen - 1 - Sold up to March 2009 Gen - 2/Gen-3 - April 2009 - current Around the time when 1.3 was finalized BMS added an additional component to the board, the blue 10uf capacitor shown in the picture. BMS and I found around 5% of cars out there needed this capacitor to run the stronger 1.3/1.4 lagfix maps. Thus the G1 board with the extra capacitor is the G2/G3 board. So what does this mean in terms of the new 1.4 software. Probably nothing for most of you unless you have an older G1 board and are having problems with the latest lagfix maps. Problems such as random 2ABC SES codes, or random stumbles only with the lagfix maps under light throttle. The 1.4 lagfix maps are even stronger than the 1.3 maps, and future maps will be stronger, so this may become more of an issue for you. If you are having these issues please email or PM me, but first please figure out what version of the JB3 you have. I would also like to make it clear that the Gen-3 board ads nothing in terms of performance or drivability over the Gen-2 board. The Gen-3 board will be important when 2.0 comes out, but we will have more info on that later on. FYI - All current JB3's ship with the Gen-3 board and the latest 1.4 software Hope this clears a few things up. Mike Last edited by Mike@N54Tuning.com; 11-04-2009 at 02:10 PM.. |

And if anyone is wondering, the Gen 3 board fits fine in the ECU compartment.

Mike, i do believe the purchase of a tuning gauge would allow a customer to upgrade to a Gen 3

So, earlier today I discovered that the JB3 that was ordered in late May of this year shipped with 1.2b, instead of 1.3. And now I'm convinced that I don't have the Gen3 board either. Any ideas what board this is? Is this the Gen1 board to use with BMS tuning gauge?

ok. I wasn't sure due to only having one blue capacitor on this board and having noticed two capacitors in pictures posted above. In any event, I'm going to have to order a BT tool and 1.4 chip really soon. I know free shipping for orders over 300 :-)
