Hello,
I have a Sparkteck 4 channel Pro 14 C.O.P. and I was wondering where should I connect the 4 wires from the coils to my Motec M800 OEM ECU.
I was checking on the OEM plugs and I saw that pin 11 is for Ignition cylinders 1 & 4 and pin 12 is for Ignition cylinders 2 & 3.
Any idea?
Anyone here that use a 4 channel C.O.P. with any OEM plugs ECU?

 

Well the OEM M800 ecu does have 4 coil outputs so you can wire it sequentially, not sure how sparktech set it up for you. Wasted spark or Sequentially?

Also, if you do set it up sequentially you will have to turn on the coil outputs in the ecu as well as change the firing order around for them as it is now setup for wasted spark.

 

You should have 4 individual outputs for each cylinder...Do you only have 2?

 

pm me the details of your order and we'll pull up the work order so we can further advise

 

Just called Motec USA and they told me that I should talk with Motec Europe-England about that issue.
I searched on M800 OEM specs and I saw that it has 4 x Ignition outputs !!!
Where?
Is there anyone with a M800 OEM and a 4 channel C.O.P.
Help!!!!!!

 

The system supplied to me was setup sequentially.

How could I do that?
I know that there are many members out there who wish to buy a 4 channel C.O.P. but they are wondering how to install them and how to set up the ECU.

 

I don't have the wiring diagram for the OEM M800 in front of me so I'm not sure which pin outs are for ignition outputs 1, 2, 3, and 4. Also, sparktech instructions or talking with them should let you know if the coil inputs and outputs are set up for the firing order of the motor. Meaning is ingnition input 1 for cylinder 1, ignition input 2 for cylinder 3 or cylinder 2, ignition input 3 for cylinder 4 or cylinder 3, etc.

Right now it is setup up in the software for only 2 ignition outputs and wasted spark as that is how it is from the factory. You will have to enable the other 2 ignition outputs and then set which crank tooth for each to fire.

Are you the one tuning the car or do you have a tuner for your Motec? Your tuner should be able to set this up in the software no problem once the wiring is done for it.

 

These were quickly downloaded from Motec's site. These along with the instructions included with our system should help you out. Pm me if you lost the instructions supplied with the system and we'll gladly email them over to you.

 

Motec should have 4 ign outputs.


Heres the way it should go.its the way i setup haltechs with msd dis 4.should be same way.

Motec ign outputs 1,2,3,4----->to MW ign input 1,2,3,4-------->to coils 1,2,3,4 if you want to run direct fire.

 

He has an OEM800 board... slightly different than gold box...

if you send me an email, i can tell you the pins for the additional ignition outputs...

also, i can configure your map if needed.

Ah missed that...didn't see a listing for it on motecs site. Does the OP have the instructions for the motec unit?

 

Edit: Somebody already mentioned that's the Universal diagram.

 

I had already sent the diagrams to everyone that wishes to help.

 

Pin 9 and 12 of the OEM plug is not in use....
Pin 11 is for Ignition Cyl 1 and 4
Pin 12 is for Igntion Cyl 2 and 3
If that help anyone...
