Hi,
keen to understand the BMW engine map part number as fitted to the HP2 enduro (or other HP hex heads) can anyone help please?
my K25 R1200GS 0307, Jul 2007 build, got an engine flash when sold new in Jan 2008 and for 10 years my K25 had engine map 07717143, this was very quick everywhere, but gets knock under abuse at high temperatures around 6300 rpm and has awful fueling below 3250 rpm (without a power commander)
I subsequently found out 6 months later they "developed" engine map 07719873 to "reduce knock, enhance idle stability and improve cold temp running" - this went on the bike recently (by BM main dealer) and it has ruined the bike completely. Its now gutless everywhere, with a flat spot from hell around 4500 rpm, and cold temp fueling is over rich by miles
Looking about I can find little information but I can see the ecu, knock sensors and throttle bodies are the same parts on both the stock GS and the HP2 bikes, I can imagine the mapping is different along with compression and cam timing / lift, however knowing the engine map would be interesting information as I now wonder if mine always had the HP2 map
