Thread: gear ratio table

Now that I have the 6 speed didnt know if anyone has this table already?
AEM doesnt have a cal file for a Specv so luck finding it there.

I searched on AEM forum and kinda know about how im should be able to figure it out with datalogging while driving each gear... although I imagine rev'ing out 4th 5th and 6th gear might cause me trouble with the blue light people. lol


Anyone know a way to figure it out just based on the ratios listed in the FSM??

This is the table I want to fix..

I played around with the car on jack stands trying to figure this out... I want to look better over the logs I took while I had it in the air.

If I feel good about my changes, i'll post the graph for it.
2006 Spec-v gears with 22inch tires.

Interested in the jack stands method.

When I had the 4.785 Final I couldn't for the life of me figure the settings, and now with the 4.437 I never bothered to even check those numbers again. On the stock 4.176 with AEM base it read perfect.

The DE startup cal only has 5 gears used on it

What I mean is that even the DE tranny with another final and the gear table didn't work and I could not get to modify it to suit. So I'm interested to see if you get it to work, even if it's on a different tranny, so I can learn how to do it.

The method described on the AEM Forums didn't work at all for me.

This thread helped me kinda figure it out...

Calculated Gear Setup

I was kinda rough it in by watching the ratio as i rev'd without logging. With the logs I saw I should make another adjustment to 5 and 6.

Nissan Motor Company Transmission Gear Ratios

I know what the gear ratios per the FSM are, but thats not how they work in AEM

What i got so far

sorry didnt read full post
