Low battery voltage reason for slow starting engine?

[A4XRBJ1]

Hi guys,


I love the Hondata (now that I finally figured out to datalog :) )

I've uploaded both my .cal and my log file of me trying to start the engine cold. As you can see from the log I only have 11.7V when I turn the ignition on (seems pretty low) and it goes down to 9.9V when I press the start button.

Can that be the reason why my engine is starting so badly? It takes about 5 seconds to get it up to run.

Hope somebody can pinpoint me to the problem area and solution.

What can be the reason for this low voltage?


TIA,

Andreas

It may be time for a new battery. Batteries only last for a few years, and are adversly effected by cold and heat.
