A write-up to follow, eventually... :D
 
I'm stumped. Did you figure out how to fool the stock 02 sensor input to ECU?
That pickup location is awkward.
Staying tuned...

This is only temporary. I got the spare pipe to modify for this reason. I know it's ugly as hell haha.

It's a wideband O2, connected to a data logger, also monitoring other engine parameters. :D
 
You trading up from RB Evo? Pretty pleased with mine.

Oh no, I'm keeping it. This tool supplements it. It lets me create a custom map based on my riding style, conditions, fuel, etc.

I'm hoping to use this to create a custom map and learn about riding tendencies. Hopefully it will be informative to others as well. Once I get enough time in, I will compile it and post everything.

Here are some graphs with very early data.

Where I spend most of the time in the RPM range, around 4000 RPM.

How much throttle I use normally, it's very low. The RB unit doesn't start adding fuel until 5%. It explains the residual part-throttle surging that I feel in town, that goes away once I roll on the throttle a little more.

A WFO run to redline. Notice how the throttle body lags behind the actual throttle position. It isn't until about 7500RPM that the throttle body actually opens 100%. Also notice how it starts getting lean at the top end. Ideally you want to stay in the 13's.

I wouldn't draw any conclusions from this yet. I am still learning, but I thought it'd be fun to share.
