Maybe there's a code for TCS for the front wheels not spinning. Maybe they pulled that code and ASSUMED that you did a dyno pull! How would it be different in a burnout with the rears on ice or water?
They did, however, assume it was for a dyno pull because I was complaining about the HP being down. This was late July, so the HP saga had just begun and they wanted to know why I thought the power was down.
.....and Mazda put multiple cameras in the earlier cars with a satillite uplink to keep track of QC from Japan. Sneaky engineers.

OK, some facts, some speculation:
1) You can get a new JSPec programmed ECU for around $900 (Canadian)
2) It is not an easy beast to "reflash". There are no socketed PROMs, they are all surface mount, and at least 3 of the chips on the board hold ROM images, not just 1.
3) Once you redo it you have to get a dealer to program the unit for your immobilizer key.
4) You will need to keep your old ECU and put it in for service at the dealer. The moment they throw your car on the diagnostics it will show if not original. While it is not mechanically hard to change the ECU ( a 5 minite job, actually) you will need to invest in a spare set of keys, and have the new ECU programmed for those.
Anyway, to make a long story as short as possible I have 2 of the JSpec ECUs coming sometime in the next 10 days, and will be playing with this a bit.
I will post my experiences with it at that time.

I can't believe I just typed that
I **think** the new RX8's are coming with two cameras with audio capabilities. With the satellite uplink, the engineers will be able to put you in limp mode, or give you the true 247 at the touch of a really big shiny red button.
