Great project and thanks for making it happen!

If you are up to considering changes I suggest dropping some of the decimal places. No need for fractions of an rpm for example.
Others needn't be more than 2 decimal places and just one would most likely suffice and be easier to decipher while driving.

thanks,
Mark

Hall sensor on the distributor

a basic android phone can be had for $29~$99 from Tracfone.
you do not need to add airtime if you are using just the basic android and wifi features. https://shop.tracfone.com/shop/en/tracfonestore/phones
and if you are planning to have it static mounted for monitoring all the time, I'd suggest a 2nd device so you can use your phone as you already have been

Any possibility you will make one for digijet? I would love one to dial in my 1.9L

Update - more work done last night:

All 20 boards are built, bench testing done, need a few final touches, clean and in Van final testing to do. Documentation still needs to be completed but is started.

I hope people understand that these are "For Off Road Use Only". If tuning with these, it is at your own risk - improper changes can lead to undesirable results.

This is a 1985 distributor, so I'll have to measure a 86 and later, but it shows just over 59* as the window size and around 122* (actually closer to 121 after I zoomed in after saving the screenshot) for the section that's not a window.

If you really want to know what the value is, I'll grab one next week and measure it. I can only get a "reasonably close to TDC" value using an in cylinder pressure transducer, but it would at least give the distributor window degrees.

Subscribed. This is a cool project.
What is the signal for on the single wire that gets soldered to the main board?
