You can use this sheet i created some years ago to test everything:

What do you mean with "4.3 is standard for AE86, 4.1 for AE86.", they both are common?

I tried your sheet but I don't have enough knowledge to see what it does?

Tire diameter, as well as an in-accurate speedometer will cause havoc on accurate speed readings.

As far as running a 3.3 final drive.... I had a 3.58 final in my E7 Corolla, and with that I barely had a need for 5th gear..... I've since moved to a 3.90.

So maybe it is best to swap to 3.9 for lower revs at highway cruizing speeds and then do the last bit with this Abbott CableX?
