The 12V switch / jumper didn't do anything for me.

Greets

Gave it a shot. Nothing.

thanks guys

Just another idea:
The parallel connected COPs might have a lower resistance
then one Miata coil.
That means the amperage? will be lower, probably to low.

It seems possible to run wasted spark sequential ign with
the EMU adding ign output channel 3+4 with corresponding
input channels 1+2.
Maybe the resistance fits better, because the COPs are not parallel.

Or adding a resistor in line to each COP will rise the amperage.

Why the ecu can handle parallel COPs, but the EMU not, who knows.

Falk

I'm not sure I can run the EMB that way. I suppose I could try resistors. I wire them into the brn and brn/yellow triggers for each COP? What ohm resistors would they need to be?

Thanks!

I have the wires put together for my cops... but I haven't had the time to test it yet. Hopefully I will be able to add some stuff to the fire this weekend.

I'm wondering if the 1.8 coils will act any differently, since they don't have a trigger wire.

Dave,

They don't have a trigger wire? How do they know when to fire then?

I suppose you mean - they don't have a tach wire. Mines also don't have the tach wire - with the EMB or EMU it doesn't change anything.

Greets

Yeah, that's what I get for typing while listening to other conversations. <G> Yeah, no tach wire.

But I thought your 1.6 ECU was closer to the 90-93 one vs the M2 1.8's..... Hum..... So I figured you guys would have the tach wire.

We'll see what happens. Hopefully I'll have a chance to play in the next day or two.

Dave,

Nope - no tach wire here. The 1.6 Nbs have the same pinout at the ecu as the 1,8 NBs, I suppose in some ways they are compareable to the later 1,8 NA.

Greets

OK, well, the testing is complete.... unfortunately, it indicates the same issue. I plugged the cops in with a "temp" harness. Turned the key, and it just kept turning over. No start, no coughs, nothin'.

Jumpered the ignition harness in the EM-B (thank for the pics, OG)... and it fired right up.

Definately seems like there's a voltage issue from the EMs to the cops. Haven't played with the jumpers on the EM yet either... figure its better to go through the manual, and have some more time for testing. Ah well, at least its a consistant issue. <G>

Dave,

Sorry to hear - but now at least we know what the bug is... (I was getting anoyed tob be telled everytime "You just plug the damn coils in and there you go..." ;) )

So - now we need someone with some good electronical skills.

Greets

i want to revisit this thread and offer some help if i can because i got around to doing my COPS today and everything went well. i changed jumper 8 to 2-3 and the car was running. not sure if others have persistent problems or got it running. i am using 2001 toyota celica GTS coils on my car.

Which EM are you running with the COPs and the jumper set to 12v????

Can we also get a few more details about your car too?

Dave,

it is a 2001 turbo with emu and jumper 8 set at 12 sorry about not clarifying. cops are pn. 90919-02238 also am running a bloomslang harness.

Tried switching from 5v to 12v on the EMB. On the EMB, it's jumper 2, there is no jumper 8.

Didn't work.

Yeah, I was reading through the PDFs yesterday, trying to figure out. Maybe if I get a bit of time, I'll try the jumper 2 switch. <G>

Dave,

HI Steelrat.. any luck with the 12V jumper 2 switch?

Hey Mini, I haven't had an opportunity to test it yet..... I haven't wanted to disturb the EM-B, or anything else, since it's been running nicely the last few weeks. Hopefully I'll have a chance shortly. If you want to try it, let me know how it goes.....

Dave,

Hi,

I think the difference to musanovic's car is, that his is a 2001. I suppose there is a difference with the wiring there (as the 2001 wiring is quite different to the 99-00 cars.

Nice it did work out for you.

Greets.

Hopefully I get to test the dwell reducer circuit soon.

Sven

i was concluding that as well. it seams there is a gray area in the 99-00 cars. as well as you do have the 1.6 i am willing to help if i can do some testing on my car to help you guys out.
