Depends on which version of the 2JZ-GTE you have ... whether it's the one with the VVTi or the one without. If it's the one without then you should be able to use the Supra wiring diagram, if it isn't...I'll post up a picture of the wiring/connectors on the ECU later on.
its the vvti one. i have in my hand the greddy bcc. there is no adjust ment in the front but if u take it apart there is an adjustment screw under neath the cover.
If you take a look at page 1 on - http://www.greddy.com/news/ultimateplugins.pdf - then look for the diagram matching up the 2JZ-GTE VVTi ECU pinout and then reference it to page 23 on - http://www.greddy.com/img/PHP/products/pdf/806.pdf - it should give you all the pin outs you need to fit the BCC onto the ECU :).
Hope that helps.
ive looked at that one. it shows just where the power and ground are. i dont see where the turbo pressure sensor is on those diagrams.
