1jz adaptronic wiring, which sensor is which? jz Hyd fan?

[Bowlsclubboy]

Got my Adaptronic in the mail today, amount of wires scared the shit outta me haha!!

About to dive in and make a whole new loom but first i need to confirm a few things.
I am unsure as to which sensors do what on the block, i know that 1 is knock, 1 is oil pressure, and there are also a few water temps. Just wondering if a 1j guru can verify the colours/positions for me.

Few more things..., i find the stock jzx81 hrydaulic fan to be a great piece of kit and want to retain it. The electrical plug on the hyd pump, if i set my adaptronic aux output to provide +12v to this when i want to turn thermos on will this work? I'm not certain as to how the pump turns on is all.

Speed sensitive steering....i only want to use this as when i disconnected it with the std ecu one time, the steering went to full hard which was kinda hard to drive with...i have the 'power steer controller' box still but unsure of what to do with it. I would imagine it needs both power and a speed signal?

Last thing. The rear sensor on my R154 is for speed and the front sensor is for reverse lights?

Thanks heaps in advance guys.

There are two knock sensors on the block (front and rear on the block).

One oil pressure, it is in the middle on the block; but the oil pressure sender should only goto the dash, not the ECU...

The water temp will be the two wire one (the 1 wire one will be the dash sender).

R154, yes the drivers side rear is the speed, the middle passenger side is the reverse lights.

If you have any doubts you can use the ECU pinouts to trace the wires back / find out what they do!

you can probably configure an output from the adaptronic to control the steering like the factory setup does. i do believe there is an input for a speed sensor. andy might have to add this into your program so that an output is triggered when speed = X

I'm pretty sure you'll need a PWM output to drive the hydro fan, not constant +12v... not sure on details though.

Thanks guys, very helpful...ive started wiring now.

Next problem is wiring the TPS Cant decypher which (colour) wire on the tps does what function.

A '4 wire' tps is explained here

http://www.createphpbb.com/phpbb/vie...rum=adaptronic

But i seem to get some sort of signal from all of the pins when i throw the multimeter on it. Do toyota TPSs differ from what he said? Its doing my head in here....

from memory the 2J TPS uses the same pinouts as the 1J, 2J info is here: http://mkiv.supras.org.nz/articles/engine_2_41.htm

If not you can use the testing info from that site to identify the pins in the 1J item

[brett_celicacoupe]

im nearly certain the above will be identical to the 1JZ TPS.

for memory, the brown is goes to earth (E2 above)

then the opposite side goes to 5V (VC)

the analogue input for the ecu is VTA. if you put earth and 5V on the above pins then VTA voltage should change based on the throttle position. you can test this with your multimeter.

IDL switches to 5V (or ground??) when the throttle is in the idle position. its just a switch basically


edit: i didnt see jp's post but it seems to cover everything

Thanks heaps guys, i ended up finding eldarOs handdrawn jza70 pinout and traced wire colours from that...so i have knock, water temp, EGO, TPS, MAP...

I'm up to CAS', Injectors and Ignitors. Been told to wire in the crank angle and both cam angle sensors so that input 1 is Crank, 2 is cam #1 (rear?) and input 3 is cam #2. This sound correct so far? The Crank angle lead is the one that snakes under the alternator correct?

I've wired my 6 new dummy ignitors up to ground and to their respective coilpacks but the input side is where im having trouble understanding.

This wasted spark and batch fire injection business is doing my head in...can someone give it to me in plain engrish please?
I drew this to work it out in my head and let all you guys know whats in my head...my adaptronic has 3 ignition outputs...would this be wired correctly, and what would the coilpacks be numbered (cylinder) left to right?


Adaptronic has 4 x injector outputs so i'm assuming i would need to use 3 of these and have 2 fire at a time, in the same order as the coils as above?

Cheers guys, i'm almost finished with the newbie questions

[wilbo666]

Wha?

Sure you don't mean to have IGN1, IGN2 and IGN3 (you have IGN2 twice!)

http://www.autoshop101.com/ (good free docs )

http://www.autoshop101.com/forms/h23.pdf as well

The Crank angle lead is the one that snakes under the alternator correct?

Correct

Coils:
I'm not sure what igniter you are running....but you will need three outputs from it (or three igniters!)
Lets call the outputs from the igniter IGc1, IGc2, IGc3.

IGc1 will goto the coil on cylinder 1
AND
IGc1 will goto the coil on cylinder 6

IGc2 will goto the coil on cylinder 3
AND
IGc2 will goto the coil on cylinder 4

IGc3 will goto the coil on cylinder 2
AND
IGc3 will goto the coil on cylinder 5




Injectors:
You will need three injector outputs...
Lets call the three injector outputs No.10, No.20, No.20 (you will need to find out what they are called on the adaptronic, and the order they are fired in....1&5, 3&6, 2&4 should be the correct order

No.10 will goto the coil on cylinder 1
AND
No.10 will goto the coil on cylinder 5

No.20 will goto the coil on cylinder 3
AND
No.20 will goto the coil on cylinder 6

No.30 will goto the coil on cylinder 2
AND
No.30 will goto the coil on cylinder 4



All this info can be found from the wiring diagrams, and the autoshop101 docs! You should check to make sure that I am right!

I actually have 6 igniters haha
Thanks heaps mate, this bad boy should be wired very shortly!

The hydraulic fan is actually run by a seperate computer, usually in the passenger side kickpanel. Hydraulic fluid flow, which obviously regulates fan speed, is controlled by a electronic valve, which is the plug in the side of the pump. The voltage output to this valve is determined by the input signals to the Fan Control Computer from the water temp sensor, 2 from the a/c circuit, distributor and the ECU. There should be a tempurature sensor in the bottom of the radiator on the passenger side. This is the one that feeds the FCC.
I have wiring diagrams for the fan computer and the power steering computer as well if you cant figure that one out. I not too long ago wired a 1JZ into my 7M Soarer so I know what you're going through.... Good luck

Thanks mate, i was hoping i could do away with that stupid amount of wiring to just control a fan...along with the nasty black boxes!

Tried to start it tonight, no go...i had my relay outputs (and still do) mixed up for fuel pump power. 87 on the relay goes to the pump +12 with is earthed to the body by the other fuel pump wire, 85 gets switch signal from aux output 5 on the ecu, 86 goes to ground (body), 30 goes to +12v off the battery...this sound right?

Anyway, seemed to get a very low voltage through the ecu wire when i checked it, this is normal i'm assuming as its one of the low power outputs?

Hardwired the fuel pump on to see if it would fire and my poor little odyssee battery laboured a bit with constant fuel pump on...but it still wouldnt go

[elhsupra]

Something doesn't sound right with 85/86. 85/86 is usually the control side of the relay, 86 + and 85 -. I would wire 86 to 12V ignition power and 85 to aux output. Then 87/30 is for fuel pump side. One to 12V and the other to + on fuel pump. Very crude drawing.

[Bowlsclubboy]

Thanks mate, i'll try that on mon...spending the weekend with the gf :/

Just found a feature on my adaptronic software under 'cranking RPM' my base map had 'minimum run rpm' set to 300, whereas my starter was only turning 170rpm. Hopefully if i get my pump running and change that setting, it may well fire on monday too. I'll take my timing light and a regular plug lead to connect to my coils so i can check spark too.
Wish me luck!
