I have a 2007 S2R1000 that currently has stock cans, stock ecu with a Fatduc O2 manipulator and Marving mid pipe. I was going to leave the bike quiet and as close to stock as possible but that did not last long ;D Picked up a used DP race ecu (96517406B) from a forum member and a used open airbox/DP performance filter on ebay. Now that I pulled the trigger on a set of Sil Moto Italia race slip-ons, I want to put it all together. My question is about the O2 sensor, with the DP ecu do you leave it in place or can it be removed? If removed does the connector on the mian harness need some sort of termination plug?
Quickest and easiest way to check is to install the DP ecu and disconnect a sensor and see if the CEL comes on.
