Chris,

For a 1JZ the on temperature for the thermo should be about 96 degrees and the off about 91, this is for a standard thermostat which I assume you are running.

Yeah, I knew that. I suppose I was just a little wary and didn't want it running too warm when it is just sitting there.

Yes the ECU switches the earth of the thermo fan but you should still be running a relay, so therefore the Wolf is switching the earth of the relay. Your thermo earth should be going staright to the body or the battery.

Yep, that is how it is setup.

Quote:


As sideshow and Cruzsida suggest the Wolf should definitely have it's positive supply directly to the battery and I would also suggest it's earth run directly to the battery too.

will look into the grounding.

The cause of the problem is simple though. When the car is put into drive there is a change in manifold pressure, more air needs to go into the engine to stop it from stalling. At this point either the ISCV is not opening quickly enough or the ISCV opens but the Wolf is not compensating enough fuel in there quickly enough, car leans out and stalls.

So when the manifold pressure changes, the ISCV should open. Could someone give me a quick rundown of how the ISCV works?

Honestly Chris, if I were you, I'd remove the factory ecu completely.

You don't go spending $1200+ on a stand alone ecu only to run it in piggyback.
The WolfV4 can run everything the 1jz has, bar the auto.

Then get an MV Automatics controller to run the auto.


Best way to do it would be to buy a cut loom from somewhere, and sell you complete loom/ecu to some chump.

This was what I was planning actually, just have to get an MV controller. Just wanted to get it running for once. I am getting a bit impatient. I don't think I will bother changing looms though as I have a chaser dash and the current loom is the only one in the car ie. no original wiring.

To make the most out of your car you would want to be able to adjust the timing aswell.

The stock timing of a 1JZ with twin turbos will not be optimal for a 1JZ with a big old TA45s on there

Smile Had a chat with celicamad and Andy (400rwkw jza70 using stock ecu) and they were both very supportive that the standard timing map is actually quite good and that tuners don't usually change it too much. The other thing was that I would then have no knock sensors.
