i held the dsc button till the sqwiggly lined car lit. and its IDS if u wanna be technical, some ppl call it M-MDS or MDS or whatev....u can manually just change the number but once u touch the gas or anything it goes back to factory settings....in the 4206f recall if the car is runnin crappy and u run the baro test and send the details to mazda, in the event the engine numbers are low, they may ask u to do a comp test, if the digits r low on that u can run the mop to 60 for a few mins to help the comp uop....if it doesnt help it enuff then they ship u a new engine....


maybe next time i run the comp test ill let ir tun a while and beat the crap out of it and then run the test....
