Wiring Injectors On Emanage For 1jz

[hockysa]

Hey guys,

Got a problem.

As some of you might know the 1JZ only has 3 injector feed lines.

I'm currently trying to wire up the injector harness on the 1JZ but am unsure of how to do it.

I'm aware I need to double up the wires on the EMB

On the ECU pin out the injector feed lines go

Line1 Cylinders 1,4

Line2 Cylinders 3,5

and Line3 Cylinders 2,6

So when I double up do I wire it up

I/J CH-1 and 4 to #1

I/J CH-3 and 5 to #2

I/J CH-2 and 6 to #3

or

I/J CH-1 and 2 to #1

I/J CH-3 and 4 to #2

I/J CH-5 and 6 to #3

Cheers,

Benjamin

Neither, pair up 1&6, 5&2, 3&4

Thanks for the reply.

May I ask for a reason why?

[hockysa]

Well this is interesting.

After some advice, I've now wired it up the ECU

EMB I/J CH-1 and 4 to #1 INJ ECU

EMB I/J CH-3 and 5 to #2 INJ ECU

EMB I/J CH-2 and 6 to #3 INJ ECU

and it won't start now.

It turns then dies almost straight away

Also I don't get why my interaction light is always lit orange without the USB cable connected

Perhaps it was suggested to wire like that for firing order? 1-5-3-6-2-4, so by having them paired like that, they'd be signaling ch1, ch2, ch3, repeat?

I too would like confirmation on that for my own knowledge I'm probably way off

Firing Order:1-5-3-6-2-4

As has been said: #1 inj driver to injectors 1 and 6

#2 inj driver to injectors 2 and 5

#3 inj driver to injectors 3 and 4

Not usre where you getting you advice from but I would cease listening to that person.

oh ok, fair enough.

Well its just that when I looked at the ECU pinout it made alot of sense to connect it the way I was advised

*sigh*

Wired it up this way. Did not start either.

[hockysa]

Problem seems to have been solved.

Wired it this way again

I/J CH-1 and 2 to #1

I/J CH-3 and 4 to #2

I/J CH-5 and 6 to #3

and it ran lumpy.

Unplugged the EMB let the car warm up on the stock ECU then turned the car off and plugged in the EMB and now everything is fine somehow.
