Diagnostic Mode ?
Can some one try the instructions on this site www.mustangworld.com to see if it works with the RX-8 ?
According to the posts on this forum www.mazda6club.com it works on the Mazda 6.

Yes and No
Yes, you can get it into Test mode by holding the trip reset down while turning on the ignition.
No, the tests are not the same as those listed on the Mustangworld site. Until someone manages to find and post the actual test descriptions from a service manual, it's merely an entertaining novelty.

BTW, pressing and holding the reset button to enable this mode will clear whichever trip is currently displayed. If you're using Trip A for your gas mileage, you'll probably want to turn on the ignition, press the button to select Trip B, then turn it off again before pressing and holding while you turn on once more.

These Are the codes that some one posted on the Mazda 6 forum - I wonder if these apply to the RX-8 aswell?
Now that we have our 6, I've been able to figure out some of the additional functions in the test mode. I've listed them below. The tests are done sequentially by pressing the reset button. It does not cycle through again. The trip meter is NOT reset if you do it right (hold in button B4 turning key to run position and hold until tEst shows up).
Test Number / Code Displayed / Function
01 / on / unknown
04 / on|off / drivers door open|door closed
08 / on|off / light sw on|light sw off
12 / oo / speedometer check
13 / oo / tachometer check
14 / oo / beeper check
16 / on (blinks 3 times) / low fuel light chk
18 / on (blinks 3 times) / unknown
22 /053 / unknown
23 /oo / fuel gauge chk
25 /oo / water temp gauge chk
all warning light check
50 / -- / unknown
51 / -- / "
31 /on|off / key in/out check *
*when ignition is turned off, you'll see "31/on" (turn parking lights on to see display); removing key will show "31/off"

Those sound pretty close to what I observed at lunchtime. There are obviously some that are unique to the 6 and the RX-8. But even though I did do the button/key sequence "correctly," it still cleared the trip meter that was currently displayed.

Yeah, ditto eccles remark about the meter reset. Also, did you notic the sweep range of the oil pressure guage? It maxes out at about the same point as where the needle normally sits at idle. What's up with that, I wonder...
I also noticed on the one that displays 23x in the odometer, the numbers change if you adjust the aircon fan speed. Didn't play with other electrical accessories though - possible it is some kind of voltage or current reading.

I'm gonna have to try this out... is it safe to drive around in the diagnostic mode???
slightly related subject - is there an OBDII port located somewhere inside the cabin? I have a friend with a OBDII datalogger that I want to check out when my break-in period is over to make sure the throttle is opening 100% as well as other things like fuel miliage and such.
