95 16197427 PCM with 94 4l60e

Yeah, I am a Geophysicist so math isn't the hard part, overthinking is. I started making it far more complicated than I needed to by actually finding out what the value meant and how it related to the other vss values then decided to assume the stock low ratio is 2.72 from a np241 and set it up as a ratio so 2.72(stock ratio)/43.539(default bin value)= (new low ratio)/new(bin value) cross multiplied then got a simple answer..... I got the same new bin values with both methods then decided to edit the XDF to show the easier way. Also tested it with my friends 95 with a 203/205 double. So individually, those values worked because 4:1 is the limit.

Here's what I setup in excel to get the values I did. Might make adding more easier.

The 94 bin already has the PWM stuff disabled. Why not just use a 95 bin like the BJYL and add the extra wire to the 95 transmission from the PCM for the pwm stuff?

Ummm...sure! That would work, too. haha Is it really that easy? I'll look for more info on it.

I've become something of an expert looking into this stuff the past week. It really would be that simple of adding a wire and changing the BIN for a 95. The wire would need to be added to pin E11 and connected to U on the picture here

lol. I fully understand how that can happen. The conversion is 1/16383.7735 * the value in the .bin. I have made the changes and have included ratios for several common T-cases in the parameter comments. This way you can enter the low range ratio directly.

Thanks for posting back with the info and spreadsheet.

Good stuff, I tip my hat to you for simplifying it even further!
