Is your ex manifold 4 into 1 or is it 4 into 2 into 1?

If 4-2-1 (not 4-1) Which primarys merge?

1&3, 2&4
1&2, 3&4
or
1&4, 2&3

I'm curious how this differs from the stock manifold!

its a 4 - 2 - 1 will get some pics for ya to see how it merges etc...

from the looks of it its

1 & 4 - 2 & 3

some pics

The really important parts are the Grounds, the sensor ground and the thing tagged Reverse Electrical Flow or something... as that's the bit that stops the injectors from blowing-up the ECU :D

We did have some trouble getting the ECU to power on the S14 and S14a, it seems to self-power in a way we can't so a relay was made up, did Dave have that on this one?

yup the one I have off Dave has what looks like a relay on there am sure it is...

The loom I supplied you is for a Euro-spec S14a. So it should all match up.

quick side by side comparison list of the two sets of pin outs, red being ones that can clearly be seen as a match.
am sure others match as well, but for different wording?

ahh so that should match the picture of the S14a pinout I posted up on the previous page

The only things I can see that don't match are the coils. Does one of them still have a rotor-arm and dizzy to distribute the sparks?

All the rest seem to be similar functions with a different name, or in the case of the grounds, it makes little difference since they are all connected together in the harness adaptor anyway.

Primera one is on the right, which is of a dizzy, I assume as there are coilpacks mentioned on teh S14 it uses them?

dnb · October 21, 2008, 12:04:56 AM

Yes, the S14a uses coil-on-plugs.

G-man · October 21, 2008, 12:16:29 AM

as I will be keeping with the dizzy and not using coil packs, will I have to make some changes to match that on the loom? to accomodate this, seeing as the loom will be designed for coilpacks...

Unless the coil outputs interfere with other functions, you don't need to change anything. Just make sure the coil outputs are turned off in the software. The coil outputs can be used as "general outputs" in the config as well as for coils.

It looks like you want to use Pin 1 for the single coil on the Distributor, I imagine that this is going to drive the coil via the stock igniter, it will be worth having a look over the wiring with a DVM. Then it would be a case of setting the Ignition Outputs to fire Stepper A (Dave can you confirm you put the wires over to the Stepper driver) four times in a row. You'll probably have to increase the dwell time on the coils.
So:

Double click download-config.bat
Go to the config folder and rename config.txt to configBeforeIStarted.txt - *
Rename tables.txt to tablesBeforeIStarted.txt - *
In Settings->Ignition Settings set the Coil chargetime @ 14V to something like 3.00 and the 6V one to something like 5.00
Click Burn To ECU
In Settings->Ignition Outputs check that Ignition outputs in use in h[2] is set to 03..00
Set the values in boxes 0, 1, 2 and 3 to (STEPPER A EC18 pin 4)
Click Burn To ECU

the software for this, which one is recommended, and where do I download it from.

I assume the ecu needs power for me to be able to connect to it?

What serial number is your unit?
I'll dig out the copy I have.
