Have you taken apart the Sprint Booster to see what the main components are inside of it?
Would like to reverse engineer one if anybody has a bad Sprint Booster let me know.
You can build one from scratch without having to reverse engineer it. All you need to do is take the voltage signals from the two hall effect sensors in the pedal and run them through a variable gain amp, and feed it back to the ecu. Or if you want something more hi tech, use a PIC/AVR processor to digitize the signal, apply whatever response curve you want via software and then do D/A conversion and feed that back. I may do this at some point if I get time but I am working other stuff first. I bet there's not more than $20 worth of components in the module. Good Luck!
