Trying to make it run (for a long time)

[JeFeRoJo]

Hello!

First of all, thank you for sharing your project. I was looking to mount something similar in a simple way and this is great. But not everything is happiness. I've been stuck with your project for almost a year. I can't get it to work.

A few days ago I took up the project again and saw that it updated the circuit (the position of the PNP transistor).

I have reassembled it following the new scheme. Same components. The code has not been modified and I think that, could the problem be there?

My car is a Honda Civic EK 1996. D15Z6 engine from the European market. I extract the signal from the cable that connects the original tacho/speedometer (blue wire in my case). I'm just getting uncontrolled blinks. I attach a small video to show it:

Could it be wrong values ​​in the code for the engine? Any help would be appreciated. I would like to make it work after so long.

Thanks and regards
