EMU + COPs on NB - difficult startup
#24
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.

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.

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,

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>

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.

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.

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.
