this sure is convoluted!
This is what you do... find a stretch of road with measured miles... then, get to speed until you hit a mile that takes 1 minute!!! hence you are doing 60mph....
read your speedo, and find out what it says... do the math, and you are done.
set the box accordingly.

Have a buddy drive on the freeway in a different car at 60mph. Follow him in the vette and see what your speedo says it is. Calculate the difference using the formula from the website and you should be fine.

Re: electronic ratio adapter ? (bogus)
Call Chris at superior chevy and buy the plastic tranny gears that are needed for that swap and send the little black box back to Ecklers.

3.54 is 1.3667 times more rev's than 2.59s were. Or 2.59s are 0.731 times less rev's than 3.54s are. Where is the big issue? :confused:
Your 3.54s are going to register a MPH 1.3667 times higher than what it really is so you need to knock the speedo down by 0.731.
.730 0 1 0 0 0 1 0 0 0 1 1 1

Re: electronic ratio adapter ? (marlon88)
Just FYI, dunno i fthis'll help or not. 3.45's get 30MPH per 1000rpm in OD.
60MPH is exactly 2000rpms for me, so with 3.54's it should be like 2050rpms..
