styggen82 Posted July 9, 2007 Share Posted July 9, 2007 HI, I am about to start intalling my Greddy BCC on a 98 supra vvt-i J-spec... Is the ecu wiring the same as described here; http://www.mkiv.com/techarticles/bcc/bcc_install/bcc_intro.htm will this work or need do I need another ecu diagram??

JustGav Posted July 9, 2007 Share Posted July 9, 2007 It is a very different ECU and the pinouts are way off. A jspec VVTi also uses a MAF sensor as well as the MAP sensor. I'm not 100% sure whether the BCC works on the VVTi or not. Link to comment Share on other sites More sharing options...

Guest KILLERMRS Posted January 16, 2008 Share Posted January 16, 2008 Did it work? I have the same problem, but the Pinouts dont help realy. Does andybody know which one to cut for the Turbo Pressure Sensor? Thank you Link to comment Share on other sites More sharing options...
styggen82 Posted January 16, 2008 Author Share Posted January 16, 2008 just use a multi-meter, and find the wire from the sensor on the manifold. trace it to the ecu, cut and install, tune it and boooooost:) it`s the center wire on the sensor, mine works perfect and I used the guide on mkiv.com, set it to 4,05 volt Link to comment Share on other sites More sharing options...

halllon Posted April 7, 2008 Share Posted April 7, 2008 When you guys say TPS - do you mean Throttle Position Sensor or Turbo pressure Sensor? I am struggling to find the correct wire myself. I can't see any yellow/brown wires in the guide, could it be either the yellow red or yellow blue? Link to comment Share on other sites More sharing options...
