I'm glad you have created this. I'm new to arduino but I've been writing code for 10+ years. I wanted to use your shift light integration to create a piggy back ecu to control variable valve timing on a subaru engine, when the car didn't originally come with it.
I hope it is okay to use your forum as the project matures.
Here is the outline.
1) Tap into RPM for y axis.
2) Tap into MAP for x axis.
3) Tap into Cam Position for reference
4) Use a matrix table (12x12?) as a for requested output.
5) Send duty cycle signal to VVT solenoid to operate VVT based on matrix table.
6) Output logger for sending the data to a computer for logging. I'm thinking rs232.
Let me know what you think.
