V70 M4.4 running COP (Coil On Plug)

[Avinitlarge]

Thought it was about time I showed this off. I've not seen another 850 or x70 running COP without any after market add on, This is done straight from the ECU. A few people have been involved in it,
Aaron Summer (Tightmopedman9) - Coding
Piet and Maarten Den Hollander (Piet and Venderbroeck) - Testing and tweeking
And Me who sorted out the ECU hardware modifications

Parts wise, it will cost very little, 12 resistors, Coil loom and coils.

Used a spare head to get the wiring in place


Then re-wrapped it to make it look tidier and to stop the wires rubbing through


4 extra contact need adding to the ECU socket, I removed them from an old socket I had



Extra resistors added


Coils in place, notice number 5 is not in the correct position


Soon sorted


Running sweet, Ignore the noisy Greens and evap valve clicking away

Had to post dropbox link, photobucket didn't like my video

After some testing, I'm going to give my opinion on the COP conversion.
Idle seems smoother
cruise seems smoother
the pull through the rev range seems so much stronger, even at high RPM
Is it worth doing, definitely.
I have eliminated most of my knock just by converting to COP

The only issue I have is a starting issue, Will keep on turning over and pop through the exhaust, May take a couple of attempts before starting

Due to TMM9 spending a long time with the programming, he is not releasing the binary to the public, he will be selling a conversion kit if any one is interested. Another reason he isn't releasing it, he doesn't wanted other tuners stealing his file and passing it off as there own.

Would also like to thank Minty for the coils and TC for the wiring

Glad to be of service

Wow that looks exceedingly complicated!

I was chatting in the garage about a similar thing : coil plugs : long shiny things, four to an engine, expensive to replace and dying periodically.
Is this different?

5 to a 5 cylinder engine
It is a bit complicated

They are long but wouldn't say shiny, They look like this

Wow, great work there. I take it you have a bung over where the dizzy used to be?

At the moment, I've just removed the cap and rotor arm. Once I remove the drive plate (Or what ever its called), I do have a cap to fit, not doing that until I know its all 101%

So are these direct ignition coils then? and what are they from?

Thanks
