If the coil look like this... (forget that gap :mrgreen: ). What is coil part number? It's not a TTL drive. You need High current ECU output, example S8 > IGBT (coil direct). https://lh3.googleusercontent.com/gnualS97dUM7X3y79-NyFzYMlEqMW7hLfaLz3-OYduwihzzRcFEljdZZfMHFieKZeQSYgQ2vAgezuKAy_IEeUYLVCWC...

Agreed - might be an error in the values Pat stated maybe? My resistors give nice even 0.4V steps: 270, 300, 390, 470, 560, 750, 1100, 1500, 2400, 4300, 10000. Thanks, I worked it all out with a spread sheet, will put up screen shot. The one I am having trouble with is how this switch works in 3 wi...

And more... ;) I do a small test today. 5, 6 or 7 1N4148 and 2,2k pullup resistor to 5V (I don't know what is correct pull up?). Temp__5D____6D___7D -20C__3,42V__4,00__4,49 20C___3,07___3,59__4,07 50C___2,79___3,27__3,72 Results in the picture With Schottky this "problem" is bigger, becaus...

It can't be work with 10k pullup.
I try 330ohm pullup to 5V and this is not good (with 6x 1N4148).

Syvecs people wakeup! What is this diode circuit and it's pullup?
And... can You tell what is goin wrong with resistors?

What is a pullup resistance with this diode "chain"? -> I try understant how this work .
And what is the type of diodes?

It is not possible to do 10-position switch with diodes (from 5V supply).

I also wish to know "good" reason to use diodes?

And some Info: These coils are designed to put out 103 mJ per spark, with a longer spark duration (2.9 ms) than what you'd see with a capacitive discharge. They can be driven with a 5 volt logic level output - we recommend a 270 to 330 ohm pullup if you're building a MegaSquirt to drive them, and t...

Is there other outputs than 8-ign. and 16 fuel injector ? 24 general purpose inputs, is there added to this dedicated inputs for knock, wide lambda and thermocouples? Can I use any NTK lambda sensor (L1H1/L2H2)? How about calibration of it? Can I get somewhere connector pin list (what I can connect ...
