fordy_alexsupra Posted May 16, 2012 Share Posted May 16, 2012 To wire the greddy bcc can I follow the instructions for the usa ecu from mkiv.com? They state to cut and wire the boost signal (black/yellow) to the bcc, is this the same for jdm ecu? Cheers,al Quote Link to comment Share on other sites More sharing options...

mattdavies Posted May 17, 2012 Share Posted May 17, 2012 Where did you get your Greddy BCC from ? did you find somewhere selling them new or is it secondhand ? Quote Link to comment Share on other sites More sharing options...
fordy_alexsupra Posted May 17, 2012 Author Share Posted May 17, 2012 I will be posting a thread with the details tomorrow/weekend, the persons name and contact ect. Mine was his first 'black box' he made for the supra mkiv, it fuctions the exact same as the greddy bcc. Hopefully the thred becomes a 'sticky'.

mattdavies Posted May 17, 2012 Share Posted May 17, 2012 ok then, and how much does it cost ? does it clamp and then release so you still get a fuel cut if you over boost ? Quote Link to comment Share on other sites More sharing options...
fordy_alexsupra Posted May 17, 2012 Author Share Posted May 17, 2012 To my understanding the greddy bcc is safer is someway than the hks fcd. I'm sure fuel cut is stall there but at a higher boost level, which is one of the benefits to the bcc. It cost £72.50 + delivery As I say the thread Im creating soon will have everything!

fordy_alexsupra Posted May 21, 2012 Author Share Posted May 21, 2012 I have linked the boost pressure wire (black/yellow) through the bcc.. Anyone know why the car tries to stall after blipping the throttle, the idle bounces up and down at 500rpm and 800rpm? There is no fuel cut though so on that part it is working.
