FUEL VAPORIZATION, DOUBLES MILEAGE

[Zolar1]

I am wondering though...

Let's assume you had a 200MPG carb and tried to put it on a brand new car.
Since the computer's fuel mapping prevents getting more MPG (unmodified controls), how would you remap the computer to accept the leaner conditions?

And what kind of emissions would the vehicle have if using such a carburetor?

Howdy Zolar1,

Easy!  Hack the machine controller.  Read the machine code out of it.  Reverse compile it into assembly language.  Find the variables you want to change.  Modify the variables. Recompile the assembly language back into machine code.  Then reprogram the machine controller.  See!  Easy Man!

Ummm....ok??

How do you do all that?

@z.monkey - do you have any hands-on experience playing with car computers?  For instance, the inventor of the Firestorm plug said in the most recent interview that it is possible to reprogram the controller via the cars diagnostics port, which I find very hard to believe!  Also, though my only eprom programming experience involved the UV-erasable types, I do know that PIC's have built-in encryption to prevent 'snooping', making them difficult to impossible to hack - and  it's a fair bet that bigoil PIC's will have more protection than those commercially available!  Of course there are 3'rd party engine management systems available but those are complete replacements rather than 'hacks'.

Howdy Zolar1,

First your going to need an advanced degree in computer engineering.  Then intimate knowledge of microcontroller systems.  Next having all the manufacturers documentation of the fuel system in question would help.  Then the source code for the machine controller and the schematic of the machine controller and all of the datasheets for all the parts on the machine controller would be a really big help.  Basically if you have none of these things there is not a thing that you can do about it.

A 200 MPG carburetor is only going to work on a car that is older that a 1982 model.  That is when they started putting engine management systems in cars.  Modern fuel management systems are not only proprietary, they are locked solid.  There is no way you could possibly hack them.  It would take you less time to build your own engine management system from scratch.  This is another way that automotive manufacturers ensure that you don't tamper with the fuel system and use less gasoline.  It is collusion with the oil companies, and another reason they make epic profits screwing you the customer.

Get a early model (early 1980's) Toyota Corona or a Celica, they have good motors.  Then make a new carburetor for it.  With the 4 cylinder motor your going to get the best efficiency.  You will basically have to rebuild an entire car to get what you are looking for because the cars that are capable of being rebuilt in this manner are old.  New cars are not generally capable of being re-engineered in this manner by a mechanic.  You would have to be an Uber-Engineer to acomplish the task.

BTW, before I was being facetious...
