800 V3.3 software basic configuration would be helpful.
Setting up the MOTEC TC software is fairly complex. Getting it to work well takes time and testing. If you've never done this before, it may be worth having one of us come to a test to help you set it up. It can save you days and days of testing and fiddling. A full description of how to set everything up and tune it would make for a good long book, so I'm going to summarize some important points and then encourage you to play with software and come back with some questions on specifics. We'll start with the options under "adjust/functions/traction control/Setup:"
Slip Calculation Mod
If you have sensors for each wheelspeed, use "Ground Speed versus Drive Speed." If you have only drive wheel speeds, select "Drive Speed Rate of Change." If you only have engine RPM, select "RPM Rate of Change." Don't worry about option 2. And keep in mind that the rate of change styles are much harder to tune.
Percentage slip works better for higher speeds, but speed units works better for lower speeds. Some systems allow you to do both and switch between them depending on speed, but MOTEC doesn't.
Use this to determine how much smoothing you want to do on your slip channel.
Driven Wheel Balance
This will depend on how many wheelspeeds you are running, and what kind of differential you have. It helps define what the speed is when you're in a turn, or whenever the drive wheels are turning at different speeds.
AIM Slip Comp 1/2
These can be used for a variety of situations where you want to allow more or less slip. One will be for your 6-position switch.
This is for tuning Launch control. We'll deal with this once TC is setup properly.
Aim Slip Filter
This can be used to keep rapid changes in your target slip from resulting in harsh control.
How you control it depends on your motor. Is it drive by wire? How much torque reduction can be safely achieved through timing retard? Are you trying to hide traction control?
These have to be tuned in testing.
Now, the first thing you have to do is setup your wheelspeed inputs under "input setup" and go test. You want to log slip so and wheelspeeds in order to determine what kind of slip numbers indicate wheelspin and what doesn't. Then you will need to update your aim slip table with these numbers activate TC, and determine where to increase or decrease the values.
In order to use your 6-position switch, you need to set it up as a "user input" in input setups. Calibrate it so it goes from 1-6, then setup an "aim slip comp" table so you can increase or decrease slip values based on its position.
I hope this will give you some ideas. Ask questions!
