2015 Corvette LT1 Driver Demand Table - How to convert to RPM and lb-ft

[djyankees31]

I can't figure out how to convert the Driver Demand table to RPM mode and lb-ft. This table just looks foreign to me compared to one in a Corvette LT4 tune file.

Any help will be appreciated!

We've talked a little bit about Driver Demand in another post, but haven't come to any solid conclusions on what tables need changed or by how much.

KonigWolf, I've read that thread too and all I can find concerning Driver Demand.

For now I just want to convert it from the VSS format to RPM. I can follow the RPM and lb-ft but don't understand why there are different formats as I don't understand the numbers in the image I posted.

What is it exactly that you're trying to achieve with this table?

[djyankees31]

HeavyChevy305, the end goal is to be able to understand and tweak the DD table if needed. However, it doesn't make much since compared to a 2015 Z06 DD table from another tune. The values displayed in the table in post #1 appear to be way high if ft-lb.

those are kilowatts, not foot pounds

the first post has ft lbs but it's axle torque so gearing affects it.

This is where I'm getting confused with the Driver Demand tables. On my 2016 Camaro SS, the stock numbers I have are much larger than those of whats in the screenshot above.
A lot of the advice on adjusting the DD tables in the links posted seem to be for the "smaller" number DD tables, what method is appropriate for the "larger" number DD table tunes?

like I said in post 7.......that is axle torque not engine kilowatts.

How does he switch it to display the way we see it?

autos are coded with axle torque and manuals are coded with kilowatts.

Thank you Higgs!

if you want to have the other tables just enable calculated vss nv ratio 1.00 then change all the values to match another vehicle of same engine and table. my 2017 zl1 has it with vss rather then rpm so I changed it over to the z06 table that uses rpm instead and kw. math to hp to kw was what I know easily and doing my ats and cts vsport just made sense to change my zl1 over to what i know well.

my 2016 cts v sport is an auto and it uses kw and rpm same with my 2013 ats 2.0t auto that I had.

My 2016 cadillac cts v sport is an auto and it uses rpm and kw. So did my old 2013 ats 2.0t auto so not all are set up that way.
