Coil Pack Wiring Query

[jbonez]

Gday

Not sure if this is the right section couldnt see an electrical area,

Wiring up an a/market ecu on rb25 series 2 engine.

I have wired it up as per this picture

White - earth - Black - Ignition switching wire - pink = signal from ecu.

Heres is an rb25 wiring diagram.

When I hook it up as it is the electrical system seems overloaded making me think its wired wrong

Can someone shed some light as ive pulled the loom back out start fresh on it make sure its done correctly.

Thats a series 1 diagram, not a series 2 like your coil packs are. You have the power and ground reversed. Try this diagram instead.

IB - Pink - Trigger from ECU

G - Black - Ground

+ - White - Connect to +12V via the ECCS relay.

These markings are on the coil pack under the plug (remove the plug to see them).

Also, if using an after market ecu use max 1.8ms charge time, 0.4ms discharge time or you will burn out the coil packs.

Thanks for the info I actually was wondering why it would be any different then any other wiring setup I couldnt understand this other diagram I was looking at but that one is a bit more straight forward.

The ecu im using is the ems 8860, Funny you should mention the basemap they have for rb25 has 3.5ms dwell I turned it down to 1.9ms so that should be sweet.

Thanks for the quick reply I should have it firing after cleaning up the loom.
