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.

Why am I and Arkmage the only two with such weird cranking PW's.

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?

No. I am seeing that in order to get my car to start after the COP install I had to lower my cranking pulsewidths.

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

I have to renew my previous question (because I think it was a little lost in my last post)-

Is someone out there running the COP conversion with emanage blue or ultimate? Could the EMB have been the cause for my problems at the first attempt to the COP conversion?

Thanks

i know it's mentioned in one of these 50 pages, but i know it can be run with EMB or EMU, but could it be run sequential ignition, i know EMU has 4 channels that can be set up for sequential, but would it work?

I just have heard that someone over here in Germany has the EMU with the COP conversion running.

Thanks again.

Um, wow? Toyota decided to explode a whole motor to keep a coil from firing a bit late?

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.

What are you guys using for Min Discharge with COPs? Maybe thats my problem.

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 asked the same thing. I wish I had the parts interchange lists. I'm sure -something- has to use it.

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

Question - on the tyco connectors, which 173631 do I need?

They have 173631-1 and 173631-6 in stock.

Brainy is all out?

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.

PM'ed him a few days ago. no reply.

What year is your car? and did you use both +12v leads that came off the factory coils or one.

so does anyone know which part # is the right one?

Are you seriously gonna order 30 dollars of crimp pins?

Well hard to say, really. I havent gotten the coils or connectors yet so i'm not sure if i've got anything comparable in my box of wires to yet but if it comes down to it, i'd either fab something up or yeah order $30 worth.
