COP Dwell time

[thilaksharma]

guys, i have wired up my sparktech COP to my Megasquirt
one thing that I am playing guess games with is the dwell time
anyone got the dwell times for the 300m COP coils would be really apreciated.

thank you

Are you talking about the spark plug gap? It all depend on many factors, like how much boost you're running, what type of gas, etc... and you're most likely going to have problems anyways if you don't a an aftermarket ignition setup.

Not too sure if this will help or not, but here you go incase it will.

Any answers on these dwell times?

Are you running a cdi box with your spark tech cop? If so a cdi has automatic dwell. If you aren't running a cdi with it then I'd say your best bet for answer about dwell times would be hop on www.MSefi.com • Index page and ask not too many guys on here are familiar with dwell times and megasquirt. I know when i set up my ms I could use other peoples dwell times as a starting point but have to change them based on my application even if they had all the same ignition components. You'll also have to specify whether your running the coils full sequential with 4 coil drivers or just two.

I'm running COP with my EMS and the dwell adjustment is not in mS it is in %. Anybody else running a COP w/o CDI on EMS?

I used to use the 300m coils without a cdi. Had nothing but problems, you have to let them charge longer than you would stock coils. I would try this set up.
Coil Dwell Factor 30
Dwell Max 1.06 teeth
Dwell min 0.10 teeth
See how that works
