COP Thread
#1041
If it helps, the only thing I changed was the cranking and running dwell times (and even that some people are still debating about) after installing my cops. I'm all stock aside from a MSPNP 9697 and the COPs. The car has started down to about 40F coolant temps.
There also seems to be debate on how COPs effects timing. I find it hard to believe it could be several degrees advance or even retard at high RPMs because my engine would either be dirt slow or would have blown up by now if that was the case.

The Toy COPs have a self protection feature that curtails its on time (spark comes early) if the on time is longer than some amount. This amount extends when the supply voltage is below something like 10.5V. I have the numbers in my notebook.
Is this the problem you are seeing?

Ponder this. Arkmage has 460CC injectors and cops. His PW's start at 1.9 in 160F and finish at 3.5 at -40F.

That's hard to believe, and easy to test. Set it for 500 ms dwell and see if the sparks come early.
More likely, there are several production chips which start late on the next cycle, based on what they see in the current one. No harm, no foul.

I'm headed to the PickNPull tomorrow in search of COPS.
If I find any, I'll purchase the coil connectors tomorrow as well.
Question... are there any other OEM applications for the Mazda ignitor. My goal is not to hack up any part of anything and I'd like to source a spare one. Perhaps in another BP-engined car... Escort or similar?

I'm pretty sure the protege one should work, it's the same motor, but I've also heard mounting it can be a pain. Personally, I'd remount the coils somewhere else, somewhere with airflow.
But, think about this:
Toyota COP can be had for $15 each.
A MS-II can be picked up for $250 with case.
It would be cheaper to buy a COP set up and install a MS to run it than to buy a factory coil pack. :-P

I started collecting all the bits to convert to COP before Christmas and I decided to go for it this morning. Armed with my trusty snippers and soldering iron I connected everything up and... it only went and started first time and I didn't even have to change my cranking PWs to get it going (could this be becuase I am running the Hi Res code already?).
I tweaked the VE values a little and now have a smoother idle and am hoping for some better mpg as I'm only getting low 20s to the (UK) gallon... In total this has probably cost me about the same as a top end set of leads so I think it's well worth the effort.
