MISC PARAM- FUEL ECONOMY ALTERNATOR CONTROL

[dvergara]

good afternoon hondata.
I have a voltage problem with the 9th gen FB6. The car is running normal at 14v and in one second the voltage drops to 12v .. this stays for one or 2 seconds and then returns to 14v

We already did:
validate that the option of fuel economy alternator control is disabled on the map
battery change
groun revision
single belt change
crankshaft pulley revision
alternator change

Could this be a Map glitch? when the voltage drops to 12v the mix goes to 16..17 AF

Without the calibration and datalogs showing the issue it is hard to guess what it might be.

If you go to the Online menu and return to stock, does the voltage do the same thing?

tks Hondata.
we already solved the problem. A bad electrical installation was affecting the voltage
