Don't know about vvti, but definatly 94.1 to 96.8 non-vvti.
The ecu still has the pin for the plug, but the wire is not connected to the plug, and I assume it does nothing inside the ecu. I removed it on my harness for fear of damaging my new ecu, and it runs fine...
94+ JZZ30 does not have +B1, only pre 94. This info is from factory Toyota diagrams.
I removed +B1 when I got my 95 ecu (91 setup originally), and she runs fine...
Those fenders and the hood don't look to be lined up very well at all... .5" gap between passenger fender and door? Hood no where near straight. If the body parts conversion is that sloppy, I wonder what shortcuts were taken under the hood.
I'd keep the SC... I'll bet the 240 will be constant...
Looks like you have a Supra harness and a Chaser ECU. You will need to:
a) Get a jza70 ecu and plug it in.
Or...
b) Get the connectors for a Chaser/Soarer ECU. Splice them into the appropriate wires, then plug your Chaser ECU in.
Good luck.
Yes, the "plasma direct" products are the coil+amp...
But the application listing for the 2jz supra is for the "booster direct" product... which is amp unit only. Look at the "item" column in the listing.
Notice how much more expensive the plasma direct coils are for the 4 cyl motors...
Glad to help...
I'm not sure of the A/C connection. I have not done my homework on the function of all the A/C wires yet, as I still need to get mine hooked up as well.
As far as factory wiring is concerned... On the ECU, pin 20 of connector C86 is a BL-R wire, and it connects to the A/C...
The component is a diode, Mine came out of the Soarer in the jdm driver side kick panel. I have no idea if it is present in the supra, but my 94 4runner does not incorporate one for this purpose.
I don't know much about different types of diodes... but simply, they only allow power to pass...
I don't think it should cause an idle problem... I ran with mine disconnected for a while with smooth, normal idle. when I finally hooked it up, the only difference is it bumps up idle a bit when I turned on the parking lights (no heater hooked up yet).
I'm pretty sure it just senses loads on...
I know a decent amount about venturi action (for water systems anyway). There has to be some sort of a special cut (slash) in the pipe for it to venturi and create suction. Or a combination of a slash cut and the proper angle into the main flow pipe. Those seem to be just welded in at a 90...
