1JZ + Microtech X6 IGN + Adaptronic

[Gibbon]

Hello

Got my adaptronic e420 running the 1JZ nicely - but it's running the factory igniter.

However the factory one isn't going to last long - so I need to get the Microtech X6 one running - I thought I had it all wired up correctly, but the engine runs like crap.

I have wired up the Adaptronic like so:

Adaptronic     Loom             X6 Input   X6 Output       Coil
IGN1            IGT1 + IGT6       #1           #1                #1
                                                            #2                #5

IGN2            IGT2 + IGT5       #2            #3                #3
                                                             #4                #6

IGN3            IGT3 + IGT4       #3            #5                #2
                                                             #6                #4

So - my theory is that the Adaptronic triggers IGN1 - which is linked to Input #1 on the X6 - which fires the coils in firing order - that is 1 and 5.

Then IGN2 is triggered - which fires coils 3 and 6 etc.

I'm stuck now as I thought I had worked out how to wire it up correctly

I'm assuming that input #1 on the X6 fires output #1 and #2 - Input #2 fires output #3 and #4 etc.

So I spoke to Microtech - who can't tell me what outputs are triggered by which inputs.

Does anyone know ?

Does Input #1 on the Microtech fire Output #1 and #2?

Hah. Why doesnt that surprise me...

Shouldn't you have

Adaptronic     Loom             X6 Input   X6 Output       Coil
IGN1            IGT1 + IGT6       #1           #1                #1
                                                            #2                #6

IGN2            IGT2 + IGT5       #2            #3                #5
                                                             #4                #2

IGN3            IGT3 + IGT4       #3            #5                #3
                                                             #6                #4

Note the different coil pairings.

[Gibbon]

I can try that - but the wiring diagram for the X6 shows that Output #1 goes to coil #1, and the rest are connected in the firing order.

That is - Output #2 to coil #5; Output #3 to coil #3, Output #4 to coil #6 etc - given the firing order is 1 - 5 - 3 - 6 - 2 - 4

[CrUZida]

You don't group them in firing order though.
You group them as per the mechanical configuration of the engine.

ie 1 and 6 are the same, 5 and 2 are the same, 3 and 4 are the same - in relation to piston position (have a look with the head off)

[Gibbon]

Thanks - I will try that tonight.

I was working off the wiring diagram I got.



It says to hook it up in firing order

EDIT: Is "engine firing order" different from "coil firing order"?

Technically, no.
But the order that the cylinders are connected to the an ignitor (in a wasted spark setup) is different to the firing order.

Your ignitor outputs aren't just firing 1, 2, 3.
They are firing 1,2,3,1,2,3 to complete a full cycle.

So your coils are firing
1+6,2+5,3+4, 1+6,2+5,3+4

And hi-lighting whats happening
1+6,2+5,3+4, 1+6,2+5,3+4

Which is your firing order.

Gotcha - that makes sense.

Still doesn't help it start

Re-pined the connector so it is set-up to fire this way - it sort of tries to start once, and then just cranks. Then I need to reconnect the factory igniter to clear out the fuel.

Must be something to do with the way the adaptronic outputs are connected to the X6 inputs.

Doesn't the X6 have 6 inputs and 6 outputs ?

[Gibbon]

Ok - got it working - but I don't know why it works - doesn't make any sense

Adaptronic       Loom          X6 Input     X6 Output             to Coil
             
         /----------->IGN1------------> #1------------> #1------------------> #1
IGN1         
         \---------- >IGN6------------> #2------------> #2 -----------------> #2


         /-----------> IGN2 ----------> #3 -----------> #3 ------------------> #3
IGN2
         \---------- > IGN5 ----------> #4 -----------> #4 ------------------> #4

        
         /-----------> IGN3 ----------> #5 ------------> #5 ------------------> #5
IGN3
         \---------- > IGN4 ----------> #6 ------------> #6 ------------------> #6

This is the way the factory igniter is wired up. None of the other ways suggested above worked

Makes a lot more sense than your first post
