I ordered the Diablo with Dougs tunes, but I ordered them for 3:73 gears which will not be installed in the car until Saturday. Is this going to hurt anything while driving since my car is an auto with 3:31 gears. Also I noticed that in the custom tune section there is no place to change axle ratio, only tire rev per mile? Car seems to drive fine and is very responsive!!!

It'll run fine, the speedometer will just be incorrect.

Look again for the entry to change axle ration, I know it's in there.

I just checked again, its not there. Although it may be in the regular loaded Diablo tunes. Since it has custom tunes from Bamachips I am assuming this is why I can't change it, the axle ratio is one of the questions I was asked about. As long as it wont hurt to drive I can live with the speedo being off until Sat! Would it make the speedo register faster or slower?

You have an auto, and I read before that it will shift in a weird way if you tune for an axle ratio other than what's on the car.

I know on my Xcal2 I can change the axle ratio, not sure about the diablo though.

Glad you love your tunes, Doug is the man.

yes it is an option to change it in there......check you manual, again.....i do it everytime i load a tune

Man it is shifting fine, chirping 2nd and 3rd under full throttle! I guess its all good until I get the right gear in!

Well, if it's shifting fine, then enjoy it. I bet the car would be a monster with the 3.73s on.

I select axle ratio and all that is there is the tire revolutions per mile

howarmat

from the diablo manual

you are saying you do not have these 2 options??

These should be available for every tune just before you load it??
