Looking for $6E 3.45 auto bin., preferably vette.
I recently changed out my rear gear ratio from 3.27 to 3.45, but I'm having trouble finding a 3.45 Automatic binary file for my car. I would much rather have a the vette bin since I'm running the vette aluminum heads, I'd like to start the spark tables up that high.
If you have either the bin or the prom code, that would be great.

gear really makes no difference in the bin. I've run 2.77's, 3.27's, and 3.42's in my stock AUJL 89 camaro bin and there is nothing in it that relates to gearing.
Just download the ARAP bin which is for L98 Corvettes with aluminum heads.

The only real gear dependency involves the torque converter clutch control
The torque converter lock and unlock table settings and limit speeds are specific for 4th gear and not 4th gear.
Of course, any $6E bin file can be edited to correct the 4th gear min and max n/v limits so that 4th gear is properly detected when using different ratios.
From ARAP:

LC291 FCB 255 ; 1st GR N/V Ratio
LC292 FCB 35 ; 4th gear MAX N/V ratio

LC294 FCB 8 ; 0.8 sec, 4th gear timer

The n/v limit values shown represent rpm/mph.
If rpm/mph < 35 and rpm/mph > 30 then 4th gear can be detected.
For example 55 mph in 4th gear at 1750 rpm:
1750 rpm/55 mph = 31 which is within the range of 31-35 -> 4th gear is detected.
These values are intended to work with the corvette tire 27540R17 (approx 811 revs/mile) and 3.07 gears.
To start with, I'd simply multiply the existing max and min values by 3.45/3.07 resulting in 39 or 40 for the max and 33 or 34 for the min.
You should end up with something like this at 55 mph in 4th gear with 3.45s:
2000 rpm/55 mph = 36 which is within the new range of 34-40 -> 4th gear is detected.
Or simply drive the car in 4th gear and observe the normal mph and rpm in 4th gear to determine a reasonable range to accomodate both the full size tire and minispare in your car, if you ever use one.
Proper tuning of these values ensures that the independent tuning of the tcc for 4th gear (O/D) and the other gears is maintained as intended. It also lends itself to additional custom tuning as desired. Also used for 4th gear hi-way mode spark.
If rpm/mph < 35 and rpm/mph > 30 then 4th gear can be detected.

Re: Looking for $6E 3.45 auto bin., preferably vette.
Ok, does anyone know where I might be able to find these settings? I'm using TunerPro RT with the 6E extended XDF and I can't find it anywhere in the bin. Thanks.

You can easily add them to the xdf file yourself. The addresses have been provided in my original post
With the mouse hovering in the constants area: right click, Insert New XDF item or Insert Copy of XDF item, edit the addresses and names accordingly, save xdf.
