Whats up ery body, I'm back. on a 2012 cbr1000rr now checking in.

With a slip on, and a pc5 downloaded map, do I delete 02 sensor or leave it?

 

Smart looking machine.
When I had my PC 3 fitted and mapped, I was advised to delete the O2 sensor as it messed with the map, for what it's worth. I actually left the sensor in essentially as a blank and disconnected the plug and connected the PC blanking plug which was essentially a resistor to fool the system into thinking that the sensor was still fitted.
