Hello,

I was working on a MPC-20 configuration (2.8.10546), I was looking for the variable value that contains the TSC1 throttle value that is transmitted onto the CANbus (SPN 898).

I am looking for this variable handle/value to make an edit to the controller send a throttle command on a proprietary PGN/SPN where the Byte mapping does not match the standard TSC1 throttle PGN/SPN (so I can't just edit TSC1 Message ID and call it a day).

Looking under Engine Control App, under the Applications tab, I see

SPN 898 Engine Requested Speed
Raw Requested Speed
Raw Requested Speed Multiplier

I then created a gauge variable for each of these on the main display page, start it up using a CANCapture simulation in manual mode, and all I see are 0's on the digital text gagues, so my question is, is the actual throttle variable exposed for use elsewhere, and if so, what is it?

I talked to the developer and he said those three variables are for input to set the target RPM value. Try looking at the Engine Control App variable Engine RPM Feedback (ordinal 19). Of course, it will be hard to send a propriety PGN at the same 10ms rate as the TSC1 if you need that.

boyce,

Thank you for the response, that is the variable I was looking for.

The application does not require a 10ms transmission rate, so that works out as well.
