Now I'm switching back to some information on the plug 'n play device that shifts the lambda (AFR) of a stock Narrowband oxygen sensor.
Narrowband O2 Closed Loop Shift, progress report.
Proto 2 of the Narrowband shifter seems pretty well set for the R1150 series. I have found an interim connector supplier at a too-high-price but it does allow me to have some preproduction units built. (Proto 2 Photo below, it needs to be prettied up with black cable, etc. Also, there is no exposed chip on the production unit) and it is very watertight.
For installation: the idea on the 1150 would be to pull the tank, connect the connectors in-line with the stock O2 sensor, run the grey cable along the right side, place the O2 circuit on the air filter cover, and attach a ground to the battery.
The specs look about like this:
(S1 means setting 1)
S1 14.7:1 (stock)
S6 14.35 ±0.15 AFR (2% richer)
S7 14.15 ±0.15 AFR (4%)
S8 13.8 ±0.2 AFR (6%)
There are a lot of steps to get a product to production and to market but there are some resources at nightrider.com to work those issues, can't say yet on timing.
