I would get this scanner instead. http://www.auterraweb.com/dynoscankitwindows.html
It give 16 sensor's real time data + fuel mileage info. It also gives you the status of all system self checks/readiness monitors. We use this one daily and it works great! It can also work with a Palm. It is not the cheapest one on the market, but the only problem I had with it was resolved very fast and professionally.

But a typical scanner should show 02 real-time for both sensors, which would tell you if there is actually a problem with a sensor or wiring. The catch - if there is truly a problem with the O2 sensor or wiring - the '97's will throw a CEL. Even for Bank 2 sensor. You can monitor the bank 2 sensor with "live data readout", but remember the car has to be driven XX number of miles before sensor # 2's voltage will be visible on the live data readout.

I can get it to tell me which monitors aren't ready, but not much more. It's a fun device, but not a great code scanner. A google search of how to do this has given me nothing. I only found a youtube vid of a guy in a truck with the Scangauge showing o2 output, not how to make this magic actually happen. I'm *this* close to buying a real scanner. My Palm-based scanner did this, but it has since broken. I'll check on the mazdaspeed forum for that monitor reset. Thanks!

It is not the scanner, it is the readiness monitor that has not reset. I think he said there were no engine codes. Adam, you can take the car to an AutoZone, Napa, O'reilys etc. and they should be able to read the codes AND readiness monitors for you prior to going back for inspection. However, if you only have 500 miles on the new ECU, you might give it a few more. The Rear O2 sensor and EGR monitors are the very last ones to reset/test. There is another method that someone on the Mazdaspeed forum came up with to reset all the monitors. You might try searching for it to see if that one will help.

I'm actually on my 2nd ECU. My stock one ran like crap (bucking and not setting the monitors) so I swapped in a spare that I bought a couple years ago when I suspected my original ecu of not working correctly. The replacement runs fine. Very smooth. but the monitors still don't set. And this new one indeed has about 500 miles on it. I'd dearly love a hardware reset button.

On computers it would be the "BIOS Reset" jumper. There has to be a way of resetting the eeprom on the stock ECU to factory fresh simply for troubleshooting purposes. Otherwise, is there another ECU in the area you can borrow? Either from a 97 or 99? Adam Wolf wrote: no, I'm not getting a code. (I'd give an eyetooth for an actual code, helpful or otherwise). it's just the readiness monitors not setting. AFAIK, the monitors deal with both o2 sensors. I will, however, recheck the sensor wiring. Wish I could get the Scangauge to show o2 sensor output...
