V70 M4.4 running COP (Coil On Plug)

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
