Fred,
Some settings require "rebooting" the MS, requiring you to power it off/on in order for them to take (some of the injector characteristic parameters for example). If the settings in the msq don't modify those type of parameters, you can load the file while the engine is running.

Justin

Phil,
That's correct, no resistors are required when running PWM mode...just be very sure to correctly set the PWM parameters, otherwise you'll burn up the injectors/MS really quickly..

Justin

Thanks Al, good info there ;)

moreover, i'm noticing following things... with just standard (mapdot, tpsdot) AE, when I releasse the throttle then ego immidiately reads rich for up to even a second (10.something afr's)



I've spent about a week trying to tune this exact problem... at first I ...

Correct!

Justin

So, correct me if i'm wrong.

The power goes to + on coil 1 and the minus of that coil to the + of coil 6 and the minus of coil 6 to a edis shannel.

If this is correct im saved and can use a verry neat setup of wasted spark on my engine.

See my page http://www.users.skynet.be ...

For each channel, you'd wire as follows (for ford small block firing order, 13726548):

+12v switched -> coil 1 +
coil 1 - -> coil 6 +
coil 6 - -> EDIS Channel 1

And so on for each of the cylinder pairs. (1&6, 3&5, 7&4, 2&8 )

Your firing order might be different, so you'd combine differnent pairs ...

Correct,
EDIS can only drive the +12v/GND style coils, not the logic level, 3wire style.

I think that's the general rule for an EDIS COP install, must be 2 wire instead of 3 wire.

Fred

The ones that I'm using are the two wire type.

Justin

Allen,
The COPs came off of a 2003 Ford Mustang Cobra, they were actually specific to the valve covers that I was using.

Justin

If you do a search on EDIS COP (coil on plug), you'll find a bunch of info related to EDIS, Waste spark, and COP's (or 8 coils as you're referrring to them).

I've been running an 8 COP EDIS-8 setup (waste spark) for quite a while now with no problems, and the car runs extremely well. You'll want to ...

The TPS is definitely not mandatory, you may be able to use MAP enrichment completely to do acceleration enrichment (that's what I do), thus eliminating the need for the sensor. The only other thing you loose is the ability to flood clear. I believe you need to ground the TPS sensor input if you're ...
