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!

oyeh2...
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... :biggrin:

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..hee

Continuing with the trend of personalized high-end sports/supercars, I recently ran into this heavily modified 997. This particular kit is from Techart and admittedly, the restyled front looks very good! Gaping air vents makes the 997 look meaner.

Now have a look at the rear:


I love what they have done with the rear bumpers as...
