That all sounds pretty cool Spockie. I've got a Mini (Aussie delivered, so definitely pre-96/OBD/OBD II - didn't notice I hadn't listed my location before) with a kit half installed (trigger wheel and hall effect sensor installed, no electrics installed/connected yet - car's' still running a dissy), and a dash that's been in the build process for nigh on two years. It's been on the road that whole time, of course. So if I could get tacho/temp off the MJ, it'd be extra motivation to install it.

That said, all my mobile devices are iOS based. No problem with Andriod, happy to concede it's a great system. Still looking forward to see what you're producing.

Keep up the great work! would love to compare notes with what you learned with the ELM chip.

We are going to integrate CAN with RaceCapture/Pro and RaceCapture/Track - this will capture all 2006+ vehicles with one chip/protocol- this will be a good start.

Just found this thread and realised just how old it is. I have completed a project based on the nixi tube Arduino project and have it up and running off my V3 jolt...

The 9 pin serial port had previously been modified to have the TTL level lines output on pins 7 and 8 and 5V on pin 1 for a bluetooth module that worked quite well...

This powers the arduino and display quite happily.. photo shows it attached to a V3 jolt on the bench hence 0 RPM

I have included an image of the display layout which shows the word "fan" after the temp to show that the fan is running (run off user out 1 hence U/Out 1 being listed too).

The other U/out's show their number instead of the _ when they are "on"

And the display layout image

Thanks Brent, i'm more than happy to share this project and source code on here.

Not used the Capri on the road this year, but running it to warm on the driveway is showing that the display is working very well.
