So this is nothing ground breaking but just my take on the Racechip GTS Black vs. JB1 w/Bluetooth. Without dyno tuning, both tunes feel exactly the same Map1 (JB1) and Race (GTS Black). With a few sloppy 0-60 runs (without torque braking) i managed similar runs of 4.2-4.5s on the JB1 and 4.2-4.6s on the GTS Black on the Dragy (im very bad at 0-60 runs).

You really can't go wrong with either:

JB1 w/bluetooth (~$620)
Pros
-Remote app control
-best bang for the buck
-data logging capability
-real time gauge readings
-change maps on the fly
-custom maps (map 6)
Cons
-Unfinished look
-poor case quality
-not water resistant

Racechip GTS Black (~$850):
Pros
-Remote app control
-Great looking and superb quality
-digital display on the main unit to verify status
-great performance for the money
-better harness
-weather resistant case
-change maps on the fly
-warm up timer (adjustable)
Cons
- no data logging
- no custom maps
- no real time gauges readings

I decided to keep the GTS black in the car just because its i prefer the better quality build/finish.

My JB1 w/bluetooth is up for sale. PM me if your interested.

I went to great lengths to find a VGA adapter cap to cover the JB1's data port. After you put it under the cover, I really dont see HOW water could get in there to be honest. Unless the user was super super careless.

Thanks for posting. Seems to summarize everything I've read/experienced regarding these 2 units.

BTW, if you locate the control unit in the battery compartment, there's little chance that it'll ever get wet. But I do agree that it's hard to beat the high-quality construction of the RaceChip products.

The real strength of the Stage1 is the custom tuning ability, and future upgrade path to a JB4 with CANbus data and more control.

I wonder if you have an older model? The latest model has a nice water proof enclosure.

I'm too late to the party, I would've picked up the bluetooth of you.. I believe that the newer versions of jb1 are water tight, that's why they are $479 now vs. $379 for the old units. While I have the old unit (bought it used and he had it for over a year before me), I haven't had any problems with it. As far as the custom tuning ability, jb1 has map6 which you can custom tune boost setting in 500rpm increments, starting @ 1,500rpm to 7,000rpm
