Hello I expect this has been asked before but I did try a search and couldn't find a definitive answer... I have an 1198S which had slash-cut Termi end cans fitted when I bought the bike. When I turn the ignition on the text 1198S RACING scrolls across the dash which suggests I have the DP ECU fitted. The O2 sensors seem to have been removed - there are two blanked off ports in the exhaust and there are two what I assume to be probes in a box of bits I got with the bike. The "dB killers" are not fitted. My question is - should the flapper valve in the exhaust operate with this set-up? When I turn on the ignition, there is a whirring noise from that region of the bike, and the valve seems to move then return to the original position. Is this all normal? Thanks in advance Andrew
There are two types of DP ECU, one is half system, the other is full system. The half system keeps the exhaust valve (EXVL) but the full system deletes this as well. The maps are slightly different as the full system has a larger bore exhaust and cans so uses more fuel. ECU Part numbers are: 96520309B - 1198S DP Slip On, text "1198S RACING" 96520409B - 1198S Full System, text "1198S RACE EVO" HTH.
Thanks for that, sounds like I have the right ECU. Do they both do away with the O2 sensors? Also, are the end cans on a full system different from those in a full system (if that makes sense)? In other words could I just add manifolds etc to get a "full system" or would I need the whole system? Thanks again
Do they both do away with the O2 sensors? Yes. Fine adjustment of the fuel trim is done through DDS (by a mechanic) instead of automatically via feedback of the o2 sensors. Are the end cans on a full system different from those in a full system (if that makes sense)? Yes, they have a larger bore than the slip ons. In other words could I just add manifolds etc to get a "full system" or would I need the whole system? You will need a complete system as it is a larger bore than standard throughout, so the bigger headers will not mate to the (standard size) slip-on cans.
