2005.5 Jetta TDI with HHO
Hi,
I'm new to the forum but pretty well read on HHO. I have a '05.5 Jetta TDI with a 16 plate dry cell, bubbler, and MAF enhancer. Using the MAF enhancer, I've found the "lean" point at which the engine injects less fuel. I have not installed an EFIE or O2 extender, nothing on the exhaust side.

I've not seen the MPG gains I'm expecting and the car seems to get more MPG when the MAF enhancer is set on the factory setting opposed to more lean condition. Check engine light also came on telling me to get an emissions workshop.

Anyone have an experience with turbo diesel hho injection? I'm injecting the gas upstream of MAF sensor directly into the airbox. Do I have to mess with the O2 sensor? My cell is producing about 2lpm.

Thanks.

Have you messed with the OS sensors?

The normal way is to see the bubble-output. For that you need alot of amps.

But for saving you will need as less as possible current. Then you wil not see bubbles but savings.

My car had no savings when I used greater as 6 Amps. At 2-3 Amps I reached the good saving zone.

RE: 2005.5 Jetta TDI with HHO
I agree with martinruf. 2 LPM is way more than you need for a 4 cylinder engine. You're probably using over 35 amps to get that. You should be down around 8 or 10 amps max, and probably less. I would run it at 8 amps, and then test other amperages to find the best fuel mileage.

Semi trucks run best at about 1.25 - 1.5 LPM. Now this is a real, honest LPM, but that's about what they need for optimum gains. Your Jetta needs a fraction of that.
