Hibino Posted January 27, 2011 Share Posted January 27, 2011 Hey guys, Long story short: Got an R32 GTST with RB25DET NEO (NISTUNE) and R33 gearbox. Speedo has been hooked up to work with the 33 gearbox BUT the speed signal is different from R32 to R34 for the VCT. Nistune can see the signal but it's all over the shop. Is there any way to convert the speed signal to something the R34 ECU can use? How do I get around this problem...? Variable cam gears and forget about VCT?

Moodles2 Posted January 27, 2011 Share Posted January 27, 2011 I thought VCT was purely based on RPM input? Link to comment https://www.sau.com.au/forums/topic/351877-vct-speed-signal-r32-dash-to-r34-ecu/#findComment-5644255 Share on other sites More sharing options...
89CAL Posted January 27, 2011 Share Posted January 27, 2011 As did I....... In FC-Edit the option for changing VCT is what Revs you want it to turn off (pretty sure). If you sit in neutral and rev the car slightly it should click on Link to comment https://www.sau.com.au/forums/topic/351877-vct-speed-signal-r32-dash-to-r34-ecu/#findComment-5644259 Share on other sites More sharing options...
Hibino Posted January 27, 2011 Author Share Posted January 27, 2011 That's what I thought but apparently 34 neo's need speed input as well... Power FC's/etc are different so they don't use it.
