Not in the least, I walk the earth doing the right thing as often as my imperfect self is able...

On the other hand...what you see in the mirror...

Wow, I like that.

It's become very apparent

To me at least

That you like to smack the hive, then step back in wonder & amazement, as you're being stung............

(Sounds like you're expecting too much from "Mr. Turd in the punchbowl". After all...He says he's doing the best he can! LOL)

Though I'm skeptical that the VX is programmed too rich from the factory, I will be interested to see how the OP's modifications work. If it does help, I'll wonder if this mod is compensating for another issue (like O2 or MAF).

I think the bigger issue with going lean is to the converters. They die first. Engines can tolerate leaner than stoich burn ratios as lower loads. At WOT, it's a bad idea.

How is this much different than the IAT trick?

I never wanted one either.

The ozone holes being smaller could be due to the reduction in flurocarbons and the like since th 70's. I know us here in WEst Aus can lay claim to one of the bigger holes and some of the worlds highest UV.

I have kids so events of the future are something I think about, but in the end it's my kids that have to deal, and they will. I remember my gearhead Dad telling me during the 70's fuel crisis that I probably wouldnt be able to enjoy 'motoring' (as he quaintly put it) because there would be no fuel any more. Yet we still have fuel, and the air in a lot of cities is vastly better than it was in the past despite exponential population & vehicle growth...

I think there's enough of us doing our thang to make a planetary change happen, and that Global Warming is a fact, but I also believe the Ma Nature has many ways of restoring the balance of things, most of which we ain't even seen yet. And I'm quite sure the redress of the balance wont necessarily be pleasant either. If we were at the start of an Ice Age Global Cooling would be the catch cry OMG OMG!!

Currently I think its a bandwagon for anyone who wants media time, and a vehicle to gather sentimental support for politicians.

Dunno about there boys & girls but here close to 75% of the fuel price is govt tax - and it is levied as a % so the higher the price goes the more they rake in.
But we digress .... How's the device working out?

Speaking for OUR ECU, which is probably programmed a little differently, when you hook up a bank of sensors and watch behavior you can see where the poor fuel consumption is coming from.
At 20% TPS ign was +40 and A/F was 14.2, At 25% the ign was +12 and A/F was 12:1.......ANY kind of load saw these numbers, with the A/F dipping into the mid 11's at WOT. The system stays in closed loop a lot of the time and has knock sensing so the setup is odd to say the least.

So a lot of the time they are rich and retarded, and thirsty

We are nerdy enough to have got access to the tables in the ECU, but not nerdy enough as to read them & know what they mean.....

Wow...Are you sure that's "normal" for the fleet of VX units? If so, it shows that the WOT circuit must be set to engage at 25% TPS. That's certainly possible -- as it's a "trick" for tuners to do this to make a performance tune/motor seem snappier. It also shows why the people getting the best MPG drive (and I quote) like a tennis ball is under the gas pedal.

Running in closed loop is normal. That's what all motors (should) do after open-loop warm-up. Closed loop means the O2 sensor is providing feedback to the ECM for correction of the fuel trim data.

14.2 is the correct stoic ratio for ethanol (E10). So, that part would be correct -- unless you were running 100% gasoline.

Not a VX - hence 'our' ECU - Jackaroos. Four 3.5 manuals behave the same way.
Well aware of it as a tuner trick - have done it - but not usually seen on OEM setups. Pretty much ditches everything from 25% TPS upwards.
With O� and knock sensors it could be much leaner & more advanced a lot of the time
The supercharged units are returning much better fuel economy than the stockers despite being driven with somewhat more *cough* enthusiasm
