I/O table for LS1

[Wockie]

Hi Can you send me a copy of an  i/o table for an ls1. I have tried to design mine and seem to run out of aux outputs. This ls1 is going into a nissan silvia s14. I will require speedo and tachometer. It's a shame the idle stepper uses 4 outputs.

The I/O is very dependent on what you want to control.

If you list all functions that require switching and it out numbers the available auxouts  the solution is going up an ECU to get more I/O 

Or maybe go to wasted spark to free up 4 outputs.

[Wockie]

Thanks for that Simon. Can you please give me info on wasted spark. Will one Link storm (black)  output drive two LS1 coils. Can you show me a circuit diagram for hooking them up.

Hi Wockie

Image attached from the help file.

In your case there will be no igniter so will be wired direct to the coils in the same order.

Simon

Thanks for that. My coils have 4 wires going to each coil pack. +12v, Power Gnd, ign signal and signal gnd.

The ignitor is inside the coil pack.

so do you mean I can parallel up coil ign signal wires  1&5, 2&6,3&7,4&8

 

Simon

I worded that wrong

If firing order is 18726543

do I parallel up 1&6, 8&5, 7&4, 2&3 wires that come from ecu ign 1 to 4 outputs and go to the coil pack ref signals

Another Question:

Shared inputs:

 With the Storm (Analog volt 2), if used. does this mean that digital input 4 cannot be used? and vica versa. Does this apply to the Storm (Black)

Correct on the firing order wiring and just sharing the output.

On the Storm Black it does not apply, But on the earlier storm versions you can only use that pin for one or the other.
