ecu
By reading some of the posts you guys have i noticed that the ecu on the mp5 is crap or not up to where it should be, any suggestions on a mod chip or where to get it, also i heard a guy wanting a speed 6 ecu would that make a difference? any of you done anything to your ecu's?
oh and is that +20 hp chip you see on ebay a joke or what?

The "search" button is your friend.
Ebay speed chips are a rip. there is no chip for the mazda ecu....ever.
swapping ecu's for another mazda model is useless unless you get a MP3 ecu. it has slightly advanced timing and should provide about a 5whp gain.
the protege ecu's are junk. This is true. In order to fix it you should by some sort of stand-alone fuel management and have it tuned on a dyno. There is a lot of power to be had from tuning alone. Wagner took the AEM ad modified it for the protege. A stock P5 on 87octane and only a road tune (no dyno tuning) showed an increase of 14whp 10lb/ft (numbers may be slightly off). this is with no timing adjustment or high octane fuel. With 93 octane, bumped timing and corrected fuel curves I bet you'd see a 30hp gain just from tuning. Thats the difference between a P5 and a MSP.
