I' been trying to detremine which controll system to buy.

I've heard of programs that allow you to hook up a Laptop to your Autos CPU. It seems ( not sure) that it would allow me to control O2 sensor, MAP, MAF, And Ignition timing! Is this a good idea!

Ive not heard of any other way of controlling your Ign timing. it seems to me that retarding the timing when Using HHO would be helpful in obtaining max HHO boosting performance.
