PDA Dyno...Here I come!!
Well, yesterday I purchased a Palm m515 PDA, and plan to order the PDA Dyno with OBD-II cord tomorrow from Nology. This tool looks very promising indeed!
I will keep you all posted.

Good luck w/ it none the less....

Oh, that. The Apex-i thingy. Ok. But remember that the S-AFC will only open in open loop operation. When you go WOT and Closed Loop, it will be of no use!

Well I got it yesterday, but I only had time to load the software, go to sleep, and on the way to work display meter data. This **** is on pimp status!! 
I have yet to run the dyno program, but I am reading up on it while watching the Bourne Identity at work. By the way, at highway speeds at 40 Degrees F (4 C), the Coolant temp stays above 180 F (82 C). After running and gunning in a short boosted burst, it goes up to about 185 F. When I park it and let it idle, the temp is around 196 F (91 C). When I turn the engine off, and let it sit for a second, the temp goes to 212 F which is 100 C (or boiling)!
I will have more data when I change out the stock thermostat for the Mazdaspeed thermostat.
Oh, and I cleared that pesky Check Engine light. I checked it again when I got to work, and the same code was pending to make a return (code= P0421- Warm up Catalyst Efficiency Below Threshold (Bank 1)). This code could be a number of things:

Well I finally got a fairly accurate dyno from this little device. Here's a little history:
I did my 1st Dyno runs Saturday morning on the way home from work. For some reason when I did my 1st runs, I wasn't even getting 30 HP.
So I go back to the manual, and I look, and yes, I was following instructions ....so I thought. You see you need some input variables for this nifty program to calculate the variables:
File – file name.
Weight – weight of the vehicle including passengers.
Gear Ratio – the overall gear ratio of the vehicle, which includes transmission and axle.
Tire Diameter – the vehicle tire diameter.
Temp – current outside temperature.
Elevation – current elevation.
Humidity – current outside humidity.
Pressure – current outside altimeter pressure available from www.nws.noaa.gov. Altimeter pressure is different than barometric pressure.
Drag – drag coefficient of vehicle.
Frontal Area – the frontal area of the vehicle.
Note – an optional text note.
The thing that stood out was the gear ratio..cause I know I have more than 24 phuckin HP!!
Note that it says "the overall gear ratio of the vehicle, which includes transmission and axle."
If you go to the MP3 Specs page you will see the specs for the gear ratios for the MP3. It turns out that I misunderstood the chart. In the section where it says Overall Gear Ratio, I used the 13.575 for 1st gear. While me, my brother were out going to Blockbuster Video, I realized what was up after I got another run below 30 HP. I vaguely remembered what the 3rd ratio was and pluged in 5.3 (accual figure=5.378) and went for another run. I got 167 HP and 165 TQ! I did another run, and go 146HP, and 155 TQ. I guess Heat soak was setting in, but then I remembered that I had some extra weight in the car. I accounted for the extra weight, and adjusted the temp a few degrees (according to my temp gauge) and did one last run. The result was the following:
Peak Power: 161HP
Peak Power RPM: 5400RPM
Peak Torque: 182lb/ft
Peak Torque RPM: 4000RPM
This sounds about right with my stock exaust at 6 PSI. Of course I will have to do some more runs after my exhaust arrives in about a week...then the boost goes up!
Some things to note:
Our cooling fan comes on when the Coolant temp reaches 207 F (97.2 C), and goes off when the temp drops below 200 F (93.3 C).
You must use the overall gear ratio that is specific to the gear you intend to do the dyno run in.
More to come.....
