ecu flash

[yamanista]

I was wondering if anyone knows if the o2 sensor can be left in place and will it function in a correct fashion after the ecu is flashed with a dyno tune ? The advice given here about the rear sprocket was dead on.

thanks yamanista

Yes it can.

I think there is a thread dedicated to this

From what Smithabusa told me, yes it can and I believe they encourage it for fueling down low.

Fyi the o2 sensor had to be turned off during ecu flash and dyno tune
