	Is it possible to speed up and configure OBD-II PID on ME7? « on: October 20, 2023, 12:32:47 AM »

Anyone know where on ME7 is configurazed what PID will send? And is it possible to speed up refresh rate?
Or if refresh rate can't be speed up, maybe to disable sending some unused PIDs(like for emmisions) so the mains PID speed up refresh rate

Sometimes I want to see engine health via ELM327 and some aplication on smartphone. It is easy, there is a many alternatives for this faster and better. But I thought maybe somehow ECU can be modified to send let say boost, MAF value etc.
How is possible that thoes can't be modified?

If you want to reverse the very slow OBD II comms and modify what it shows for what PID you can do that of course.
Epic waste of time though.

There are many messages in the ECU that are completely unused (disabled via CW_CAN_S).
If you are making it for your own need, you can enable one of the disabled messages and then put whatever you want into it.
