What Ecu i should put to a stock b20z ?? I bought a b20z but without ecu and know i have problems. Will p72 do the work if not what ecu would be the best, maybe there are couples of ecu's that can be put on a b20z if yes which ones fit ?? If you write sth about an ecu write also in which car i can find it. THX

 

you can use a pr4, p74, or p75. these all come out of the integra ls. what obd is your b20?

 

What car is the motor going into?
