Does this work?

Heres what could be inside:

Several resistors connected to the switches to cause the computer to read a colder air temp than actual.

This will cause an increase in ignition timing up until the knock sensor reads knock.

Most of you are dedicated to low octane garbage gas, and already banging on the knock sensor. Thats why your VX gets better mileage initially after you reset the ecu. The knock count isn't yet high enough to pull timing.

Wait a tic, so you are saying that resetting the ecu might yield a slight, temporary increase in MPG?

YES.

You could even wire up a kill switch to the ECU power as theft preventive feature, and thereby benefit 2 ways from shutting it off after every trip.

This is free, try it and see. Oh, and keep the tranny in power mode too.

I see no harm in a new person asking about these things but, being that we do get tons of these threads asking questions like this, it does get tiresome especially with gas prices being what they are.
Unfortunately, if you bought the VX for a mileage wagon, you bought the wrong vehicle.
Without sounding rude I hope, you will learn to accept it for what it is, or like others, after they grow tired, they sell it.
