Power hold problem on a M800

Postby konstantinosIX on Wed Mar 04, 2009 4:59 am

Hello,
my issue is the following.
I installed on my Evo IX a sparkteck 4 channel COP with Pro14 CDI.
From that day my M800 has power on all day.
I cannot find why it isn't cut the power when I turn the ignition off!!!
The things that changed was the warning light when I made the change from 2 channel to 4 channel but I send the warning light to IGN5 through ECU manager instead of IGN4 that was at first place but the same power on issue is still going on....
This problem keep my ECU on all day until my battery goes dead!!!
I used the 22 wire for IGN4.
At first place it was for warning light with Power Hold function (CEL)
Do I have to wire the 22 cable to 57 that is ECU relay via warning light???
I have the warning light wire off now and I am thinking that this maybe is the problem!
Any help with that?

I used wires 11 . 12 . 22 . 41

Yesterdat I tryied to send my old 2 channel rom to my M800 and after that when I turn the switch on and off there was no power hold.
I sent the 4 channel rom again and the problem was there again....
Searching for a solution....

When you make your wiring changes somehow you are connecting a unswitched 12Volt supply through a device into the ECU outputs. The unswitched power on the output feeds back through the output circuit and keeps the ECU on.
