Hi sorry for the noob question because I'm first time wiring and setup the speeduino,But I'm a bit confused how to wired the the CYP,TDC and CKP to the UA4C pin,and also I'm not actually used distributor rather I want to use Coil on Plug.

If you guys can guide me and or even better any schematic diagram for wiring will help me out.

Thank you for helping in advance ><

If you intend to use the distributor, just use the single 4 tooth wheel and select Basic Distributor in ignition settings.
If you want to use coil on plug or wasted spark, you have a couple of options.

1, Use the 24 tooth wheel as primary trigger and the single tooth wheel as a secondary or reset then set this up as a toothed wheel with second trigger

2, ADVANCED - Cut a tooth off the 24 tooth wheel and use that on its own as a 24-1 CAM mounted/speed single missing tooth wheel- read the manual to find the best angle at which to cut the tooth in relation to TCD and your first cylinder.
The speeduino code allows full sequential because it has 720 degrees of crank rotation to reset as the camshaft turns ad half the speed of the crank.

You will need to use a VR conditioning module with any of the above and any Honda that uses a distributor (1973 to 2000, with the P2K oddball ecu found in NZ and Australian EK civics being the exception)
Good luck

The first question is the fueling scheme you plan to use, as there are several ways to use a Honda 3-wheel for sequential, semi, quasi/paired and batch — with multi-coil. Let us know which fueling scheme you plan, and we can work multi-coil into that.

BTW, so we are all on the same page for 3-wheel Honda distributor signals we can work with or modify:
  • TDC - Top Dead Center sensor. Triggers 4 times per engine cycle, at each cylinder's TDC.
  • CKP - CranKshaft Position sensor. Triggers 24 times for each cycle (12 per crank rev).
  • CYP - CYcle Position Sensor. Triggers once every engine cycle at TDC of cylinder #3 (180° after TDC #1).

Appreciate a bit of help with a pair of 2017 to 20[…]

I don't know the signal form, so I would try jumpe[…]

Voltage ±10% is fine for testing. Note GM […]
