Forum hello!
I have a question about ignition time.
In my car i use the scangauge2 to see ecu data.
Before use HHO the igniton time when my car idle it was +10 or +15 degrees advance.
I have electronic control ignition time.No manual.
When i use HHO tha ignition time drop to -6 or -8 dregrees.
This is correct?What happend and the ignition retard at idle?
I have to inform you my car idle perfect and sound very very quiet!like no ignition!
I have connect the HHO also in vaccum line of inlet manifold and before butterfly(2 outputs).

Thanks.
