Building a FE D-Series trans for my CRX VX

[crx driver]

What year hf is the spreadsheet for?

It should be pretty much the same for all of the 2nd-gen HFs (88-91).

slight tangent here, but would someone with a mpguino or the like mind doing a simple test? I'm just curious what your instant mpg reading is say on a flat level road crusing at around 55mph in 5th gear (preferably in a vx or civic with the long gearing) as opposed to exaclty the same situation only cruising in 4th gear... I'm just curious what the difference is in mpg at that exact time for reference purposes... Thanks if someone will let me know!! I currently have a Y7(dx) transmission in my car, and running a vx in 4th gear is pretty close to my car in 5th gear, i'm just curious of what the instant mpg difference would be..

P.S. Props to you for taking the time to do this with an excel spreadsheet, but this Honda Transmission Calculator by ZealAutowerks would be a little quicker for ya.

I think this is a very wise idea for a project; Thanks for keeping things fresh!
