Howdy All,
Been a while since I updated properly on the status of this, but I made quite some progress on the ECU Diagnostic stuff for my 2nd gen a couple weeks ago, I intend to make a nicer video but I have one here:
http://www.youtube.com/watch?v=hMSnguTxjIs
This shows an LCD cranking out a whole stack of values from the ECU, Accel Enrichment, RPM, Fuel Trims, Injector Timing, Oxygen Sensor, Airflow, etc, etc, etc. It's also not shown in the video but I can crank out all the fault codes at once without playing waiting and guessing games with a test light.
Project is slightly stalled due to lack of working 2nd gen.. hopefully be sorted shortly ;)
A friend of mine with an RX-8 who is also working on this stuff is presently using a very similar platform but to speak to his RX-8, it uses the ODB-2 connector which is the same sort-of hookup that the 3rd gens use - but still using some embedded-style hardware rather than a laptop so you can hide it away and keep it data logging, etc.
For interest: http://www.practicalarduino.com/news/id/331
All in all this is a-lot more gadgety and fun than probably of interest to the more direct car-nuts but hopefully it entertains some of you ;)
And for those of you that don't know, you can get some laptop software & cables to do the same thing for 3rd gens which might be more practical if you're interested at a basic level:

Probably set you back ~$100-$150 depending on what cable you get for what features. If you have any questions feel free to ask. Does supposedly support 2nd gens too but it wouldn't play ball for me.
Now I've got that working my first real project of usefulness is to make a fuel consumption trip computer (because the TS doesn't have one!)

Enjoy!
