richard lyew, you might want to read these two threads to get an idea of what type of evidence members here would like to see.

How to properly test modifications (AKA: don't believe every MPG claim you read)

So you want to talk up your new fuel-saving product on EcoModder... (I realize you haven't attempted to sell anything yet, but this thread is still relevant.)

With respect, posting a couple of YouTube videos that show amazing numbers on a fuel economy display don't quite count as quality evidence.

You were adjusting the long term fuel trim right?

So what was the short term fuel trim?

You should be happy then because you haven't convinced anyone thus far.

Somebody call up that other pro tuner because you're doing an awfully poor job of explaining anything.

i saw the correction factor at -50%, and i then saw the rpm at 388 RPM (according to his meter) and yet his tach showed about double that. so let's see, 780RPM Idle reduced by 50% (hence the "-") and you get 390 RPM. seems to me like he did the equivilant of calibrating his SGII to read that he was hardly using any fuel when he was using the normal amount.

And just to be clear on a couple of things,

SAE did research hydrogen to support leaner fuel trims. Their findings were yes it worked, but that the savings weren't worth the extra complexity.

If you had claimed a 2%, 5% or even 10% improvement some people here might be more inclined to believe you. But a 3X improvement.... no. Your going to have to really show some good proof.

Does anyone know if an O2 sensor will give readings on H2? Or does it have to be a hydrocarbon?

Everyone knows the bigger the lie, the more likely people are going to believe it.

Seriously.

And an O2 sensor measures oxygen in the exhaust. Hydrogen will not affect it.

I would assume that you can use your APEXi to datalog. Can you output sensor data into a CSV file for importing into Excel?

CVS? i want one of those little computers that you guys use to measure MPG so i can connect it to the output signal of my AFC which the car's ECU is getting so you guys can see.

where do i get one of these devices?

this car dont have a back o2 sensor and im porting my HHO after the MAF right at the main intake right next to the idle intake. the idle intake for this car is a hole right above the main intake butterfly, shown here idle air intake - SaturnFans Forums
