[V8] interested in increasing fuel economy?

[Steve B]

Cool find!  Since my cars are 5-speeds it wouldn't be of much help for me, but I am interested in increasing fuel economy.

I had a situation where I was running on 7 cylinders due to a plugged injector.  The engine seemed to run fairly well this way, it just had a rougher idle than it should.  Nowadays manufacturers are designing the control systems to shut off cylinders in low load situations (e.g. current model GM Trucks).  By any chance have you come across groups that hack into the ECU to try to make changes to increase fuel economy?  On the PT the injectors are paired, so you would have to shut off cylinders in groups of 2.

A forum member in Germany hated the fuel economy and decided to get an engineer involved and they developed an add-on box that makes the transmission kickdown come in earlier. It even looks like the units might connect directly to our transmission control units without their having to change the software. My question is, would anybody be interested something like this?
