RSO and RSC is both for the ISCV (under the ITB),the ISC pin is for A/c idle up VSV,separate from ISCV....i will confirm this once again when i went back home,i got one SVT engine wiring lying around somewhere...hope we can get a clear picture on how VSV is connected to ecu...yes yes...R&D is the way...i likeee!SVT n BT use similar ISCV...
but then...
BT ECU got 2 connections, RSO and RSC ...
SVT ECU got 3 connections, RSO, RSC and ISC
refer to this :
BT
SVT
hahahahaha...this is getting way off... :D :D
One wire to ground,another wire to your a/c compressor....may i know how to install ficd on evo3??? i am budak baru.. help me.. i f u got a diaphgram please pm me how to install ficd on evo3.. tq
Of course if dont use the a/c idle up will be problem,idle too low...cause as discussed in other topic,the a/c ampilifier is different SVT and BT,but on SVT auto i think its the same characteristic..heeoyeh2...
I bet that's the one...
BT - RSO n RSC direct to ISCV, A/C idle controlled by ECU directly...
SVT - RSO n RSC direct to ISCV too, and ISC goes to VSV A/C idle-up...
last time my SVT converted to BT wiring (RIP)...initially, i didn't use that VSV...only after the A/C idling gave a problem...I installed it back...
