Air/Fuel Controller Installed

I think it's pretty naive to think all the carbon waste we put in the environment gets "absorbed" and causes zero damage.

I'm no expert or Al Gore fanatic (since I'm driving a Corvette and VX), but I think trivializing the issue is ignorant -- to say the least.

Yeh...I'm ignorant as hell...

But on the plus side for me...I've never even wanted to own a vette...not even when I was 11......

And to be a bit more Burnsian...(Frank)...I have 0 children, I have reproduced 0 times, I have 0 heirs, &...to top that list...

I have 0 cares...what will be, will be...don't believe a word of it, matters not to me, for some day...

worm food... we all shall be...

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...

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............

Smack the hive

Being stung

You sir are delusional

They've got this new thing, it's called a metaphor...

(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?

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.

Wow, I like that.

I never wanted one either.
