Advance Timing Controls

[bergs23]

Anyone using timing controls to advance the ignition for better fuel economy?

just use a AFC. look into it

anyone using an AFC on an ECU??

With HHO, you want to RETARD, not advance the timing.
The introduction of Hydroxy results in a much quicker burn rate.

My understanding Top Dead Center is the point of full compression before power stroke, and the time it takes for gasoline to burn/combust you need to RETARD the ignition 20 degrees before TDC (set from the factory) so the explosion(force of the gasoline) is on the down stroke. Now when you add HHO it speeds up the burn rate and you then need to ADVANCE the timing toward TDC. (instead of being say 20 degree its now 15, 10 or 5 degrees before TDC, depending on amount of HHO)

you need to RETARD the ignition 20 degrees before TDC

and you then need to ADVANCE the timing toward TDC.

Yes your thought is correct, but the names you are using are backwards.

Moving timing further before TDC is Advancing. ( from 20 too 30 BTDC)
Moving timing closer to TDC or even after TDC is retarding ( from 20 too 10 BTDC)

Can we all just agree that retarding it will make it fire later and advancing it will make it fire earlier? TDC is only the reference for the degrees it needs to be at. It's either before or after TDC.

Thank-you. At least someone gets it!

It seems most anti-knocks sensors handles the retarding.

Most of the newer cars and trucks the timing is automatically advance according to the data the ECU received from multiple sensors on board.

So according to this, just adding the HHO generator will be enough to gain improvements, yes? Do you need to reset the ECU or anything else?
