I finally upgraded my ECU to a PM7-905 from a 1991 Civic Si facelift model (JDM).
WOW. Theres way more power now, especially down low. I don't have to change gears just before max power anymore and the engine also doesn't blow steam in the cold anymore, or burst smoke on hard gear changes.
Definately a happy me. 8)

PM6 - 1.6 D16A6, SOHC ZC
PM7 - 1.6 DOHC ZC
Theres a range of different PM7's, as with the PM6's. The one i got was the last type they made, it has minor adjustments in the A/F ratios (especially down low), reads the sensors a bit differently and has a cleaner rev limiter.
