After some extensive reading and googling, I came across a product called Ultra-Gauge
I believe it was discussed heavily on Mazda Speed Forums;
Product shipping was blazing fast, I recieved it 1 day after ordering. (From US to Canada... wow)
If you're looking for a cheaper alternative to the Access Port or Scan Gauge product, this is it.
It allows you to customize and set up to 8 pages of gauges, with a maximum of 8 gauges per page.
Upon plugging it into the ODBII port it automatically detects the car, and loads all the possible gauges into the settings.
I use it to monitor engine temp, fuel PSI, voltages, Boost PSI, and a few others.... set to 2 pages 4 gauges a page. Automatically changes pages every 10 seconds.
This is all customizable and totally user friendly.
Grand total of $100.00 USD w/ shipping, for the version with suction cup mount and all the goodies.
The only thing this gauge doesn't do is log and record , but I suggest you check out their webpage and read up on the features it does have
