Any body have luck with E92.REQPWR_DMA ?
When i tried to log it it seems not supported in GM E92 Trucks
any help will be appreciated

On the PID, you can check the needed parameters to see if there is another PID not selected that may also be needed to read correctly. The E78 has the same issues.

This is what is done for calc pids... but this is not a calc pid... this is a DMA pid, these are defined only for particular OS's.

As an FYI, 'any' PID that ends in _DMA requires a lot of time for us to define, sometimes a few hours just to add 4 or 5 PID's PER ECM PER OS so you can see how they are quite demanding and unfortunately often neglected.
I'm not sure how useful ' 'Exx.REQPWR_DMA' actually is though, it is just gives the result from the pedal > KW tables.

I'm fighting to keep throttle open for a FI E92 cars
So i think if i know how much torque the peadle request and compare it to the actual torque i can put the correct numbera in torque tables

You could create a spreadsheet in Excel to convert the KW numbers to a desired torque figure, would that help?

This is SUPER useful Ross.... and not necessarily will give out what is in the table.

You are chasing your tail.
