SOLD
FS: JB4 with data cable. $225 OBO shipped. Was on the car for about 4 years/30k miles, works perfectly but now I'm moving on to open source tuning.

There seems to be some confusion about the groups of the JB4, considering all of the FS threads with the specified group in the title. All groups 1-3 are identical, this was on my 1.8t, but it will work the same on a GTI, golf R, A3, S3, sportwagen, alltrack, etc... There are no hardware or software differences between the groups 1-3, it's just used for internal tracking at BMS.

Thanks! So far it's going pretty well, making tons of power and installing MPI soon. We're still trying to sort out a bug with the throttle sticking open after letting off at higher rpm, but aside from that it's pretty much everything we ever wanted. Also, I've made progress on getting the ECU to understand my new gear ratios.

Btw there seems to be some confusion about the groups of the JB4, considering all of the FS threads with the specified group in the title. All groups 1-3 are identical, this was on my 1.8t, but it will work the same on a GTI, golf R, A3, S3, sportwagen, alltrack, etc...
