Thought this community might be interested in the Arduino 4L80E controller I've built and is currently working in my 77 turbocharged Corvette.
4L80E is a very heavy duty GM electronically controlled 4 speed overdrive transmission. Widely used in high HP applications.
Here is some of the basic functionality:
It controls the 4l80E. Has multiple operating modes including cruise, sport, burnout and drag mode. Each mode has its own shifting strategies, boost targets as well as other characteristics.
PWMs all the fans: 2 radiator, 2 intercooler, trans cooler and oil cooler
PWMs the two fuel pumps
PWMs the alternator
Connects to the AEM infinity engine management with CANBUS
Controls Boost in each gear in each mode
Displays alarms from AEM or itself.
Triggers the AEM two step
Controls the backup lights
Controls the brake lights
Scramble button
Fuel level sensor
Paddle shifting input
Line pressure input
Shifter position input
4L80E temperature input
7" touch screen display and control center. Also used to edit hundreds of operating parameters and save to NVram .
