MUT Requests
Revision as of 00:11, 6 October 2009 by EdwardMarshall (talk | contribs)
The following table attempts to collect the requests that are query-able via the MUT-III protocol on stock vehicles. Not all entries will apply to all Mitsubishi vehicles. Formulas are expressed in a format compatible with EvoScan.
Please Note:
- "Calculated" formulas (sometimes referred to as "math channels") are intentionally not listed here, nor are common modifications to the MUT table.
- As we understand it, MUTs are only used for logging purposes. Changing a MUT value should have no effect on internal ECU calculations.
- Many of these were dreived from Acamus' list here.
Only request IDs 00 through BF are valid MUT requests. IDs higher than BF are actually MUT Commands, which control actuators for various functions driven by the ECU: solenoids, pumps, etc.
