racelogic traction control module So I've got one of these going on the car. I thought this might be the place to pose a thought I had.
Since the way the module works is cutting individual fuel injectors per revolution, could you program it to shut off cylinders to maximize fuel economy while cruising on the freeway? I'm not sure if complicated tables are required like if it is a certain throttle at certain rpm and vehicle speed/gear, it would run on only 6 cyl or 4? Anybody have experience with these? Was just a wild thought. Maybe I should post in advanced engineering or whatever. Let me know.

Yea. I just thought that with how complex these things are, they might have capabilities for other things (i.e. better cruising mileage). I'll be sure to let you know how it works. I'm pretty excited as I've heard incredible things.

If you set your O2 switchpoint voltages lower in the
airflow ranges that represent highway cruise, you
will get a closed loop lean cruise for free. Put the
wideband on, and try pushing them down from 350-
500mV (various platforms have different values) to
250mV, 200mV, 150mV in the cells at/about the
airflow values you see in the scans. Not so lean in
areas you hit with a little more load, like climbing
grades.
Be nice to know about the Racelogic unit but you
do have this other option.
