How To Wire a 1JZ ISCV with MicroTech LT12s

**131OWN** · 21-11-2008, 11:20 PM

Just wondering if anyone knows how to wire a ISCV from a 1JZ up to a LT12s? The OEM Wiring Loom has been completely removed all I have is a plug. Any help would be great?

Microtech's can't control the factory 1JZ ISCV.

a guy on here did it 2 years ago, so it can, its just a bit of buggering around.

he had a jzz20 soarer, he was from adelaide from memory.

I wouldn't have thought the Microtech would have the 4 control wires left to run it properly?

do a search on here, use a 4age 20v iscv the microleb can control that.

All that is available is 2 on one of the aux as far as i could see looking at the wiring diagrams and an actual unit i bought attached to a loom, unless i missed something?

and the iscv from a 20v 4age is 2 wire ;-)

It depends what you said when you ordered it.

If you ordered it to be programmed batched injectors, then you'll have 3 spare wires that Microtech *may* be able to configure to run an ISCV.

If you've ordered a standard setup, then chances are it won't.

That said, I haven't heard of anyone running a Toyota 4/6 wire stepper off a Microtech.
