I've always liked this, but I have not tried it yet, buy arduino uno, and board nano, which of the two I should start with?

Digital Pin 5 -> DIODE -> COIL 2
Digital Pin 6 -> DIODE -> COIL 3
Digital Pin 7 -> DIODE -> COIL 4

Digital Pin 8 -> 1k Resistor -> ICM
Digital Pin 12-> 1k Resistor -> INJ1

Also , I'm using 5v instead of VIN as power, 12v from the car is not that stable. So I connected the 5v power to D19 which is power source for MAP (5v power source) , so power goes like this :

5V PIN -> D19
GND -> B2 , ANY GND IS GOOD

Also , I'm not using the ECU Pins for coil output, I'm using direct cables with a connector , I guess its easier .

Attached the ZIP FILE with the code.


Cheers
finally it worked?

I'm waiting for someone to send me a test board for a new product, if that doesn't happen really soon I'm going to try this out with so,e ideas of my own.

In regards to what spadam was saying, the pins where the stock knock board connects carry timing signals for stock knock windowing

I am not sure if they've been processed to edges by then as I haven't scoped it yet but it makes sense that they would be. But who knows.

Didn't know the stock knock board was capable of windowing! Neat!

I assume so, don't know why else they'd put all the sensors there. I haven't looked into it much deeper than that.

Hi, did anyone get any further with this at all?

I read this post prob 5 times. Loving what im seeing here. Wondering if anything else been figured out. I have a Nano on the way and plenty of things to test with it Im looking forward to this!

In code you mesure the icm signal and after this, you charging coil ~2ms. 1ms on 1000rpm is ~5 degr Drive shaft , but on 8000rpm 1ms is 48 degre. So how is it that the ignition is not delayed.

I'm sorry for my fatal English

Hi. Good day fellas. Need a help regarding the wiring diagram. Can you guys please share a diagram so that i can try it on my own. So many thanks in advance. Cheers

hate to say but if you need a diagram maybe you should use something more pre-made. Hondarulez has a cop board you can solder into the ecu.

i have thought about revisiting this but imho it would require proper pwm / timer manipulation on a microcontroller not just digitalwrites or similar to be reliable and good..

i might look into doing it this way again, if I do I'll post my results

A circuit like this could be hidden inside a gutted distributor and the coilpacks wired directly to it.

This is this signal diagram for the counter:

I think this could also handle the tach output as well?
I don't know why I didn't see this before but it's actually a good idea.

I previously thought this, but now I'm pretty sold on the Honda Rulez setup. The CMOS logic falls short when you need to keep track of dwell. The holy grail next step imo is to utilize a delphi coilpack with ion-sensing capabilities to not only detect the onset of knock but also read out combustion chamber pressure.

Good point, I didn't fully think it out just saw your post. The hondarulez setup is pretty decent, guy definitely knows his ****.

I totally agree about the ion sensing, I was looking intomthings like this for a while.

Tbh if I can get a datasheet for those coil packs I could whip something up.
