AEM gauges and AQ1 ODBII datalogger.
Mentioned this in a another post and putting it up here so it's all in one place.
So after much head scratching I worked out how I wanted to mount the AEM AFR and Boost gauges.
The gauges are pretty much just the face-plate and weigh next to nothing so can be mounted simply. They didn't really fit under the fairing (nearly fitted, but not quite) so mounting off the two fluid brackets was "plan-B".
Some 30mm x 3mm aluminum bar and a couple of hours bending and twisting them in a vice to suit and I'm pretty happy. They don't look like much but there are lots of different angles to get the bracket and the gauge to sit right. A quick spin on the polishing wheel helped make them look more presentable too.
The AFR gauge has 2 plugs in the back, one for power and comms, the other to the Bosch 4.9 sensor in the exhaust. The notch in the AFR bracket was clearance for one of those plugs.
Both gauges came with wiring to suit, oddly the boost gauge only had serial comms wires and not AEM-Net so I needed to rewire the plug. I then made a little "loom" so the boost gauge runs to the AFR and shares power and comms, also had to terminate the boost gauge with a 120 ohm resistor (as it's one end of the AEM-Net comms). Doco also says you need at least 1 twist per inch on the AEM-Net so don't forget to twist 'em up before covering the loom.
They work really well. Too much information to watch both gauges, the dash and watch where you are going when you "give it a squirt" but nice to be able to glance occasionally when curious and excellent to have them log data so you can review off-bike later.
