New Toys!!! o2 sensor Delete and RaceBox Micro

My attiny10 based o2 sensor delete PCB's arrived and I have one put together and ready to go.
At the same time the RaceBox Micro arrived from their Kickstarter Campaign and it's looking good however the MT09 isn't exactly overflowing with great places to mount it.

I’m following your o2 sensor delete journey 😄 looking into this for my ‘24 mt09sp. But this goes a lot further then my knowledge will go about chips and programming them unfortunately. Are you gonna sell them? (I’m from the Netherlands)

You can buy them of ebay and aliexpress. I've got the electronics gear to DIY so I did, and I learned quite a bit along the way about what the ECU is looking for from the o2 sensor and the faults that the ECU will throw if it's not seeing what it wants to see.

Hi great work.....whats your purpose to spoof the O2 sensors?? To run a gen3 exhaust??
I am going to pick up my MT09 next friday....

[@davidb3925]

For me with the gen3 it was mainly to allow me to remove the o2 sensor completely. With the decel fuel cut turned off and my ignition at the time being tuned to induce decel popping I didn't want the o2 sensor to get destroyed by all of the carbon build up. The damn things are expensive to replace if I ever want to put it back to stock.
As for the gen 4 it seems that only Europe has the 2 sensor setup at the moment. Australia and the USA still only have the one sensor. The ecu for the gen4 is actively looking for a difference between the first sensor and the second so a delete for the gen4 would need to be carefully crafted and not just throw random values to the ECU. Someone tried the existing commercially available units it and posted on reddit about it. It was very educational.
