rallly Posted August 23, 2012 Share Posted August 23, 2012 Need pic's or a diagram on how to install the Greddy Boost Cut controller to my 1993 JDM Supra RZ please!! Quote Link to comment Share on other sites More sharing options...

rallly Posted August 24, 2012 Author Share Posted August 24, 2012 Here you go, http://www.mkiv.com/techarticles/bcc/bcc_install/bcc.htm I thought those instructions were for the USDM/CAN Supra TT ? Quote Link to comment Share on other sites More sharing options...
Mario Posted August 24, 2012 Share Posted August 24, 2012 this picture shows how it is installed in mine 93 jdm supra turbo Red to any 12V source Black to any good ground source Green To turbo pressure signal wire, pin 62 on ecu. White Wire connects to the Turbo Pressure Signal wire, away from the ECU(BLACK/YELLOW STRIPED WIRE) http://www.greddy.com/tech-support/misc-electronics/ ^^here you see the basic wiring diagram from the greddy site.

Thank you for the info, still not sure what pin out the white wire goes too.... Sorry but that picture isn't showing up on the forum.. could you send it to [email protected] please?

rallly Posted August 26, 2012 Author Share Posted August 26, 2012 Also, how do I install this if there's a Greddy speed cut spliced into the ecu also? Quote Link to comment Share on other sites More sharing options...
Mario Posted August 26, 2012 Share Posted August 26, 2012 ^^picture works fine for me, basic wiring diagram on the greddy site just shows you the basics. red wire to 12v, black wire connects to any good ground source. Now the green and white wire, if you look closer on the BASIC diagram(speed cut defender isnt relevant) you see BOOST SIGNAL written on the left side of the diagram, that signal is going through a wire which originally went straight towards the ecu. You also see that that wire is cut, marked by an X, now you see the white wire which is now connected to the wire where the boost signal is coming from so it enters the bcc, but you also want to pass the signal through towards the ecu so thats the green wire which is connected to the wire which goes towards the ecu. Thats about it. Hope this helps you as I cannot explain it any better. Quote Link to comment Share on other sites More sharing options...

Red wire = 12v Black wire = ground Green = what JDM ECU Pin out?? White = what pin out #?? Quote Link to comment Share on other sites More sharing options...

Guest supra&starlet Posted June 12, 2014 Share Posted June 12, 2014 quick question gentlemen. I have installed a speed for sale BCC (same as greddy BCC) on a 1994 JDM twin turbo supra automatic. I have installed it using the instructions you guys have provided. My problem is that i cannot seem to find the sweet spot by adjusting the voltage on the BCC to get it to stop hitting fuel cut. I turned it counter clock wise all the way and the car shut off. I turned it clock wise all the way and it would hit fuel cut at 4000 rpms and would not pass 4000rpms. I have it adjusted somewhere in the middle, and it hits fuel cut at 4000rpms then 4500rpms then 5200rpms and finally it shifts at redline. It keeps getting inter-upped by the fuel cut. I had a voltage meter and i kept measuring the voltage on the green wire and it always read 1.36V no matter how many turns i did counter clock wise or clock wise.
