MUT Requests

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.

"Calculated" formulas (sometimes referred to as "math channels") are intentionally not listed here, nor are common modifications to the MUT table.
