Soarer auto - can you run stand alone ECU? Many other virgin questions.

**waldo** · 28-10-2010, 10:41 AM

Hi guys,

Im waldo, new to the forums as a poster but a reader for a while. I have been converted to Toyota and will be purchasing a 1JZ driven Soarer next week.

My back is in Nissans and manual transmissions so when it comes to the auto Soarer Im a little lost as to what to do. I have read many posts on the Soarer Central forum but this has confused me more. I have some experience tuning Wolf ECUs using just a simple Innovate LM1 wideband. I am by no means an expert and have much to learn.

On this forum I can see that some are using autos with teh 1JZ and running stand alone ECUs, my question is how is this done?

(Does the stock ECU run the auto and then the stand alone ECU run fuel and Ign? If so, does the stock ECU still require feedback in terms of fuel and ign?)

Basically I already have a GT35r, Eboost, intercooler and Link ECU for the car and would like to use these.

Another question relates to the auto.
What must one do in order to handle more power?
Ive seen people run certain lubrication (which one and why?)
What is a shift kit and where can I get one? Can I do it myself?
Should I run a trasmission cooler? If so can an oil cooler be used (sorry if this seems rediculously obvious, to me they look the same)?

What options do I have for the factory open diff?

Ive seen the ex camgear can be good. Which one to get?

Where is the stock boost cutout?

All other info and suggestions welcomed.

Thanks so much!

Waldo

There is a dedicated Soarer thread in General Car Talk lots of the guys there will be able to help most convert to manual as soon as they can perhaps this might be a better option for you.

Thanks for your info. Didnt see there was a Soarer specific section. Thats great.
(do I ask a mod to move it or do I repost?)

Just leave it one of the mods will close it if you ask them and just ask the question again in the dedicated thread.

There seems to be no active dedicated soarer thread that I can find.

Lets put the soarer aside for now.

Can anyone help me out with these questions below:

(1) Can we run a stand alone ecu on an auto car?

(2) What must one do in order an auto to handle more power?

(3) Ive seen people run certain lubrication on autos (which one and why?)

(4) What is an auto shift kit and where can I get one? Can I do it myself?

(5) Should I run a trasmission cooler? If so can an oil cooler be used (sorry if this seems rediculously obvious, to me they look the same)?

Cheers

G'day mate,

I asked the same question on here a few months back, here is the thread.

Basically, because the 1JZ ECU controls both the Engine and Auto in one unit, you need an electronic shift box to replace the factory ECU's auto control. They are quite basic and can be assembled by a semi-competent operator, alternatively can be brought through MV Auto's. To answer one of your other questions, MV can also do the shift kits, or build a box to handle a bit of curry.

Oil cooler is perfect for a Transmission cooler (its the same shit)

Good luck!
