Retard timing table based off 5V input

Hi there. I’m relatively new to tuning but here’s what I’m trying to do and I’ve been told it is possible. I’m trying to put a Hondata traction control box on my Toyota. The traction box reads the front and rear wheel speeds, and when there’s a difference in speed, it begins outputting a 0-5V signal through a single wire. That wire needs to run to a GPIO (analog) wire on my harness and I need to configure a table in the EMS software to pull engine timing to reduce power until the car manages to get traction. As far as I know, there isn’t an ignition correction table and I would have to use an air temp table as it works off of a 0-5V input and can retard timing. My question is what’s the best way to go about setting this up? What values should I start with in the table? Is it going to be like building a full ignition table or will it be just a correlation between input signal and ignition retard? The traction box will vary the signal obviously. But I just don’t know where to start on building the table. Any help is appreciated so thanks in advance!
