How to calculate TC slip.

zstroken said:
I would log the data, and you could get fancy and use a calculation to factor in engine load.
Since at low engine loads your slip should be less.

I thought you meant a calculation to generate engine load. I figured you were aware. I should have used a question mark.

So using the following calculation:

(((ECM_RPM*31.8)/(3.42*Gear_Ratio*ECM_Speed*336))-1)*100

Slip parameter calculates to about 10% when TC is locked. That is the stock tire height from the spec (probably not an actual) and I goofed the axle ratio. It should be 3.73. That accounts for around 9% of it. I'll tweak the tire height to calibrate it to 0%. Then if it reads anything else under a load I'll know it is slipping.

I think i asked this before, and i know i asked about the software UI, but is this all written in java or C+ or?

Nope. It is all done using a software configuration tool.

That looks like a "skinned" java IDE.
Is a product purchase the only means to get their software?
