These units are expensive but seem to be able to do alot. They can control pwm and engine sensors. And is programable for different rpm ranges. Makes sense to me because it makes more hho when you need it and adjusts sensors for different rpm ranges. The only difficult thing is the time to program it and determine what works.

I have not purchased one yet. I just wanted to know if it is worth it. Does anyone know of people with these units.

Here is a link http://www.hhokitstore.com/p26/VMU.2.Vehicle.Management.Unit.Computer/product_info.html

I think you need to spend around $1000
I think the computor is $770 and you need a cable and probably the power box, which I think is a 30 Amp pwm.

That unit would be great for commercial usage in developing HHO systems but not for end-users. It is way to steep of an investment for me. I just stay with my MAF enhancer and O2 sensor extenders and anytime i change my system i get my fuel:air checked and calibrated correctly with a wide band meter.
