PR3/PW0 ecu and Zdyne ECU? As much as I know about hondas and acuras there are few areas I still know little about the ecu codes being one of them. Im hoping some one will be able to help me out with this.

 

the pr3/pw0 are both obd0 ecu's. zdyne is a system used to tune these ecu's.

 

this still dosent clear up the difference tho the reason why im asking is for a swap in to a total sleeper that im looking at doing if any one can auctually clear up the difference for me i would greatly appericate it thx for the help tho Qui Gon Snoop

 

Zdyne is a company that rechips certain ECU's. They are popular for their "one wire" VTEC activation. They also appear to be marketing a Hondata style modification also.

PW0 and PR3 are actual ECUs, OBD-0 B16A ECU's to be exact.

 

Kai I love you man lol thanks for clearing this up for me. This will help alot with the "big swap".......... To be continued
