Please post your Coil On Plug ( COP ) Success

Postby daxtojeiro » Sun Dec 24, 2006 3:11 am

Hi all,
I would like to get a list of dwell and wiring for various COP's as Im always being asked about them. Has anyone got any running, if so please post the make, etc and the dwell settings and a diagram if possible so others can benifit and I can then add it to the manuals :)

Toyota 2zz COPs with built-in igniter.

http://www.msextra.com/viewtopic.php?t=22817

Cranking dwell 10m, running dwell 2.5ms;

Important - the igniter needs 5V pull-up and at least 7mA to fire steadily. I feed them with 13mA through 330R resistor and it works fine.

One of the guys on Turbobricks is running Toyota COP's on his Volvo- I'll ask him to share his info.

Yup. got it working. Had wasted spark with the toyota COP's for a while, worked great, finally got the sequential COP working just the other day. Posted all the pertinant info in the my success story. http://www.msruns.com/viewtopic.php?t=22411

cheers!

PS... thanks all you MSEXTRA code people for making this such a cool/fun project!

I've done a subaru ez30r, and a honda 3.5 v6. They both had cop's with built in drivers. I wired them for wasted spark, and drove them from the led drivers with 330 pullups to the 5v, on one, and 12v on the honda. You need to set spark to NOT inverted in this setup. Both work well. The running dwell was 3.0 on both. I would have liked to do true sequential cop on the subie, but needed extra outputs to drive the variable cams, and variable valve lift. I have also done cop's in series, in a wasted spark setup driven by edis, as well a pair of vb's. Not having plug wires is a good thing!

How about some info on the strength of the spark for your COP setups?

What HP are you guys achieving?

I've done several 2 liter subraus @ 20psi ,around three hundred hp. Also a 3 liter subaru @14psi. It is around 600 hp. In all cases, I set the plugs to 24 thou gap, and don't get any spark blowout.

I am using splitfire DIS coils from an SR20, but I was wondering how do I know if it is a 12v pull-up or a 5v pull-up? Trial and error? Also, does it have to be a pull up, or can I drive them like a vb is driven (off the top of the resistors). Thanks, Nick

I'm running the LS-1 coils, the D581 type,
Just need some info on the dwell.

I have been doing some testing on Suzuki GSXR C.O.P. The early ones off the carbureted GSXRs are CDI and have very low impedance and probably would not work will with Kettering ignition. The ones off Fuel Injected GSXR 600, 750, 1000 and 1300 have 1.5 ohm primary, and spark well with 2.5-2.8 ms of dwell. Looking at the connector on the COP, the 1st terminal is (-), the 2nd terminal is (+).

VEMS cop of interest aswell? A friend of mine runs a Alfa six
Bmw m10 running fuel. Spark and boost ahead.

I tried the honda with both 5v, and 12v pullup, it didn't really matter. I used a 330ohm for 5v, and 1k for 12.

Just got Subaru SVX COPs to work, these don't have built in ignitors. Running waste spark, two VB921s from one spark output via 680Ohm resistors each.

Motec site says 1.8ms dwell at 15v, what would this be at 12v? I've got 2.3ms and VBs are heating a bit.

MS1/E HiRes running COP on a '91 Saab 2.0L turbo 4 cylinder.
36-1 on the crank and 1 per cam rev sensor (custom made)
COP unit is a Saab DI cassette (Black T7 unit 2000+ MY)

It is 'fired' by grounding the COP unit's pin. I am driving the pins from the 2n2222s. I have disconnected the LEDs as the COP unit has an internal 12V on each pin and have increased the base reistor of the 2n2222s to 470 ohm to be able to pull the trigger pin down to 0v. I have been running this since Spring 2006.

My COP unit is CDI, so it needs to have the leads held high and needs a .1ms pull down for each firing event. I have modified the MS1/E code to do this.

Cheers !!!



Any More details on the 20v? Such as:

- 3 wire or 4 wire coils (Assume 3 wire since you say you used vbs)
- Dwell Settings
- Wasted Spark or Sequential?
- ...anything else you care to add ;)

Thanks,
