*this guy needs aristo ecu diargams*

[crazysupra2JZ]

i'm stuck now. i made up my own harness for the fuel injectors to use the 550cc instead of the 440cc. here's a little drawing of how i did it. just like the 7m has it.
the 7m ecu only has 3 pins for the injectors. the supra ecu has 6. i don't know if it's the same for the aristo. if anybody has any pics of the aristo ecu diagram, i really need them. i've searched all i could. nothing turned up anything i need. thanks guys

No diagrams here, but I'm going to guess that it's SFI like the 2JZ Supra, and in that case you'll need the MKIV Supra TT resistor pack.

The 2JZ has 6 injector signals? I didn't know that. I thought it had 3 just like the 2JZ.

At any rate, you could wire the resistors up to the +12v wire on the injectors. Cut the black wire to the injectors, wire up one of the black wires to that black orange wire on the back, then wire each of the other 3 wires to pairs of injectors.

Edit: Isn't this how they're always wired?

i just found out pin 15-20 are the injector wires for the mkiv, someone said the aristo ecu is the same. so now i'm gonna try to get a resistor pack from an mkiv, which i didn't know they had
