Breva - Lambda sensor replacement

[maxray]

Well my attempt to bypass the lambda on my breva 750 didn’t do the trick as the ecu is still flagging it (used an eBay bypass kit).

Genuine part replacement for lambda sensor is eye watering - does anyone know if there is a cheaper generic replacement OR how I can turn off the lambda? I have Guzzidiag but couldn’t see anything obvious there.

Thanks!

For GuzziDiag you down load your map with Reader then you use TunerPro to change the "X" in box to shut them off. Then you put map back in ecu with the Writer part and all is well.
OR get a Beetle map & install it.
There is a mass amount of info if you search GuzziDiag

The Beetlemap for the RC15 turns off the lambda. As it's no longer needed, it can be removed. I've blanked the hole with threaded flat plugs in brass or stainless (with a fibre washer). Tape the end of the connector which goes to the ECU - just in case.

My 17 V7III had both O2 sensors fail by 20000 miles. I used Guzzi Dia to turn them off. I didn't install a new map. The bike runs great! Now at 29000 miles.

NGK/NTK OZA341-BB1 is reportedly identical, and available from auto supply stores.  This is for the older V7 bikes.  This and other interchangeable parts are listed on the "non-Guzzi parts" page of this group:
