JB4 vs JB1 install question (M135i EWG)

Post by duckson » Sat Jun 24, 2017 2:21 pm

Instead of buying a JB1 could i buy a JB4 and only connect up the TMAP and MAP sensors and hence it would run in map 1 only as default as per a JB1? i.e. not connect to the CANBUS or buy/fit the extra EWG lead or buy/fit a bluetooth lead.

Gives me flexibility to use map 2 or 5, 6 in future if i go the sports CAT, add the EWG lead, bluetooth etc is my thinking.
Current - M2 LCI
Gone - M135i LCI
