COP help
« on: September 16, 2009, 07:06:03 am »
Ok, just a couple last questions.

I have the COP unit (4 wire +5V signal) wired up 0-7 in the firing order.

Looking in the software it traverses the coils in reverse order. So I have the Ign outputs set to;

0-7
1-6
2-5
3-4
4-3
5-2
6-1
7-0

Does that look correct? I do have a hall sensor on the cam. So I should have no issues running sequential.
I would try to run wasted just to get running but it wants to do 0+1 2+3 4+5 6+7 which in order to run wasted I would have to run 0+4 1+5 2+6 3+7

Also I have the injectors paired as I needed the outputs. So I have divided the firing order in half and wired the matching cylinders together.
Now my Inj outputs look like this;

0-4
1-1
2-2
3-8

Is this correct?

I am using a divider of 2 and alternating enabled with 3..0


This is all that is needed to be confirmed on, or fixed before the car willl start.

I have already tried and it will not start as is.

The engine is 4995CC with 19# injectors. Req fuel is at 21.33

It doesnt seem to me like the injectors or ign is firing. I will be checking the plugs in a tiny bit here though.

TIA

Ok, two updates.

I have no spark that I can see and the plugs are completely dry.

So it looks like we have no spark or fuel.

I disconnected the hall sensor and got no more RPM reading while cranking.

Checking to see if I get the same from the stock VR style sensor now.

Disconnected the VR reference sensor and dropped RPM while disconnected too.

So I would say that they are both working.

Any suggestions?

Disable Secondary trigger when in wasted spark mode. Have you checked H2 table? It's under Advanced -> H2. Check that the values are IGN for first half and 0 for 2nd half of the table.

After chatting with Peep, talking to a local fellow and finding the IRC channel I found out that the 8 ign channels do not provide the proper signal to fire the COP units.

I switched them to the stepper outputs and the worked properly right away.

Thanks for everyones help.

If anyone does know how to get =5V logic output on the 8 outputs it would be helpful to know. I removed the IGBT units and bridged pins 1 &2 together, this did not work. One fellow suggested to put the IGBT units back in and to then take a 1k ohm pullup resistor and attach it to pin 2 and the other side to +5V off the board.

Thanks again.
