There are 2 different versions of the LPE 200 software in the tiller head.

1 software version for 6 kph trucks & another version for the 8 kph trucks.

Also the Toyota & Cesab versions of the BT LPE 200 also use different software package numbers again, Why BT just doesnt use the same software package for the same spec machine no matter which brand stickers are on it is anyones guess.

Newer spec's of BT machines seem to be more universal on the Curtis box spec.

I've got 3 completely different types of BT machines that I look after for one customer & they all use the same BT part number for the Curtis box / its interchangable beween machine type.
