Nissan KA24DE trigger setup Link G2

Recommended Posts

I have a Link G2 that I wired up for a KA24DE in a Nissan 240SX.  I am running the factory distributer with internal cam/crank sensors.

From research I did I found that this should be the Nissan ECCS opto 360 trigger system.

I have it set to this setting in PC link, but I cannot directly configure the triggers, or sync them.

The Cam/Crank sensor is a 4 wire system,

White signal wire

Black signal wire

Black/White 12 V

Black sensor ground

I have the white wire to Trigger 1, and Black wire to trigger 2.  The 12v is keyed on with ignition, and the ground hooked to sensor ground wire at ECU.  I just want to make sure my wiring is correct.  I had though about using the 12 CAS out from the ECU to power it, but it already had a power signal, so......

I have played around with it a bunch, and it just wont recognize the triggers, or give me any menus when I select them individually.

I bought this ECU second hand, and it came out of a running Subaru Legacy with a V7 STI swap.  After reading the install book back to back a few times, I noticed the passage saying that the correct usage should be noted when ordering so the correct, something, can be installed.  I am wondering if this is my issue, or should I condemn the ECU, or Crank/Cam sensors as having failed.

Hi Ian,

Your ECU has a trigger sub-board that is setup to work with the Subaru it came out of. You will need to have a Nissan trigger sub-board installed for the ECU to work with your setup. We have these sub-boards in stock and can do the install. Email sales@linkecu.com your more information.

It still wont give me the option set the triggers indipendantly.

All I get in PCLink is Trigger setup, and Calibrate.

Im going to try and load a new base map.

Can you tell me the settings for the rotory switches on the trigger board within the ECU.  The guy at Link USA said he wasn't sure about the settings, and to call him once I had it plugged in.  I called, and his receptionist took a message.  When I called back an hour later he had left for the day.  That was Friday.

He really did not seem to know what he was talking about, and I want to make sure they are correct.  One switch is set to 6 and the other 0.

Ok, I loaded a new base map.  No change.

I reloaded the newest version of the firmware.  (It was already up to date, and did work in the Subaru on that update.)  No change.

If I switch the trigger type to any of the Subaru's it brings up a few more tabs in the triggers menu, Trigger 1, Trigger 2, and AVCS stuff.  If I switch back to Nissan ECCS 360, I retain those options, but clicking on them brings a blank menu.  Once the ECU is reset, the tabs disapear.

Hi Ian,

Apologies in taking a while to get the rotary switch settings to you. I have found a 3 page document that includes wiring up the sensors and setting up the switches. The pdf file is attached to this post.

Hopefully it will guide you through ok!

Cheers,

Scott

Ok, I rechecked all my settings, reset both switches to 0.  Spinning the cam sensor by hand I get LED flash only on 0.  Any higher and I loose it.

With both switches set to 0 trigger 2 syncs within 2 rotations of cranking.

I still do not get sync on sensor 1, or ECCS.  I still cannot change any of the setting or see triggers 1 or 2 in PClink.

I have checked both trigger wires.  I get a low voltage with a spike on trigger 2, and a continuous voltage on trigger 1 while cranking.

Ok, on the advisement of Simon, I have switched triggers 1 and 2.  I have also switched away from the Nissan opto 360 setting in the triggers menu, and have instead selected 1 tooth per rotation.

I am now seeing engine speed in PClink, and triggers 1 and 2 are syncing.

I set up my fuel, and ignition parameters, and attempted an engine start.  I got 2 backfires in the exhaust, and no fire in the engine.  I fouled the plugs.

I have checked, and do have spark.  I need to properly set the timing, but am unsure of where to start.  I have adjustment both at the distributer itself, and then there is the second rotory switch inside the ECU.  Need to do some more reading to figure out which comes first.

I also re set the 1st rotory switch, I get LED flash up to level 4, and then it drops off.

I will double check my distributer timing.  Its not slotted, but a gear, so I could be off a tooth.

Thanks for all your help guys.

Hi Ian, 

Glad to hear you're making some progress. The distributor should be set as per a factory setup and then the offset adjusted on the sub-board.

250 rpm is pretty normal during cranking, and 2 engine revolutions is about right for the engine position to be calculated.

Cheers,

Scott.
