Seems like its worth a shot though, and I've got an HKS AFR laying around.
E-Manage powered Mazdaspeed!

Update 12/25/03:
After having a bit of experience with tuning the unit I have found it very unreliable. The factory MSP ecu is very good at negating the changes that the E-manage makes. I've been running into massive detonation above 5000rpm with absolutely NO changes to the fueling or ignition maps.
I've reset the ECU numerous times, changed the maps and changed the way it maps the changes (relative pressure, airflow voltage, etc..) and it still doesn't hold changes. It will run great for the tune that you do while the car is running, but after the car gets shut-off and you drive again, it won't run the same way as the previous run.
Because the ECU does not go into OPEN loop at set TPS or even at set RPM, the programming is very very touchy. You can add X amount of fuel to 3000rpm when at X boost, but then again X boost is variable between 20-100% Throttle... which could trigger OPEN loop and take your 12:1 to 9:1 instantly.
If anyone else has had better luck with the unit on the MSP let me know and I can try out your settings, but for now I have to reset the ecu again and set everything to 0 and hope that it doesn't keep detonating.

Any standalone is always a better choice. I had the opportunity to try something new and took it. Whether or not I'll be able to get the ECU to stop learning is another problem. It just varies too much between different drives right now.
Either way I'll continue to play with it and hope I can come up with something. Spool has informed me that the cars he's tuned on don't emit the same problems as my car, but it's hard to say what is causing this right now, my finger is pointed at the FMIC.

well it all seemed too good to be true 
... but in either case the whole protege community is grateful to you guys (especially turboge) for all the effort that youve put into this endeavour on your own time. we can only hope that you find a way to perfect the system... good luck

Too much air.
I got a chance to play with it some more and it still ended up changing back to run like stock. I made it think the injectors were 15% larger and it ran great till i restarted the car. Never went over 80% duty cycle.
So next week the e-manage comes out, fmic comes out, car is going back to stock and being prepped to sell.

A plug & play standalone would be an awesome thing to have available for Proteges 
yeh that suxs thou..i wanted a simple management system to clean up the fuel and s*** but oh well....once i get my turbo back, intake, and fmic im done with the car....its my daily driver and i didnt really want to go all out swapin stand alone systems and s***...thanks for all u have done thou turboge.....
the sti are so sick, i took one out when i was shoppin for a new car and it had so much torque.....too bad i dont make enough yet....still luv my msp......only a few more years til its paided off though
