Hondata

I have a Kpro v3 and I dont know why my car won’t start I’ve been in many forums and everyone says it’s the map. But I’ve installed new one.
So I put my stock ecu back and it worked so thinking my Hondata is bad I put it in my brothers car and it ran fine. Then I put it back in my car but only difference is I took off the taps and fixed the cables where they were alittle damaged now the ecu clicks almost nonstop and if it doesn’t click the second I connect my laptop it starts clicking video below

The clicking is the fuel pump relay. I already changed it but the problem is still there sadly

It sounds like you have low battery voltage.

The battery was charged. So I’m not sure.

What is the voltage at the ECU when cranking?

How would I check that

Would I be able to see that in the data logs.

Check it with a multimeter.
