That is also another advantage, although I ended up turning the O2 sensor flag off in my ECU when I switched to E85.
You will have no problems with the DM-5, just make sure the O2 sensor is mounted securely and it will be fine
Also, in case your wondering, I mounted the gauge in the roof mounted sun-visor of my Pulsar to keep it away from prying eyes. Flip the sunvisor down and it comes into view
