Pre '96 "OBD2" data feed into Torque/Android with an Arduino
 

I thought this was pretty clever, he must have hooked up a bunch of sensors then emulated the elm protocol directly to the bluetooth adapter on the arduino or something like that. Easy peasy ;) Might need a custom pid if you are hooked up to an injector and vss though and want more accurate mpg reading.

What is that? Can you explain more?
 

I am interested in what you did there!

What is that? Are you estimating mpg using all those sensors?

If so, please share.

It wasn't me, but I can imagine how it was done.

Hook up a bunch of sensors to an arduino, throttle, injector pulse, rpm, speed sensor, map sensor, maf, temp, etc.

Hook up a $5 bluethooth to uart adapter on the arduino

Emulate an obd protocol on the arduino (look at how elm does it maybe), basically wait for commands (pids) on the rx port via bluetooth, and give responses via the tx port, each pid can be a single reading or whatever combination of sensors morphed into a number makes sense.

pair your android with the bluetooth, install torque, and add any custom pids to torque that you need.

add gauges to your torque screen for those pids (which represent readings from the arduino)

It seems that, after you viewed the video, he added a link with more information: AllTrac.net • View topic - ODB2 data for Torque on my Android
