dear all, im facing power steering make idling problem even dead engine when im using P28 chipped for my B16A.
before tat im using P30, and turning power steering, idling will slightly turn high, means that my power steering sensor are fine. after i change it to P28, it become unstable idling when i turning steering. after i spend some time to checking, find out that P28-A51 (auto) have no transistor that locate in DM4, the Pin B8 line trance are stop at DM4. would like to as transistor code & value to install power steering switch in DM4 for support P28.

after i trance ECU line, found that DM4, R101, R102, R99 is missing. can any 1 who have P28 manual to show me or let me know all this component code. thanks.

Opened up my P28 to find DM4 was burned out and can't figure out what type transistor is supposed to be there. Any help would be appreciated.
