Hi, Yes an MDS thread, but NOT a how do I turn it off thread...
I am actually interested in seeing if the MDS feature is actually tunable.
In the Rom under Fuel > Lean Fuel Saving > MDS you have 5 tables:
MDS Active/inactive Switch
VSS Min MPH
VSS Max MPH
ECO VSS Min
ECO VSS Max
Stock values are:
Enabled
8 mph
128 mph
9 mph
128 mph
I tested and set the VSS min for MDS to 55 and the ECO VSS min to 56, and it never activated.... Almost as though the subroutines with these specific VSS tables are either not defined, or the tables themselves might be mislabeled and other subroutines don't see this as actual Vehicle Speed... Also, maybe there are other switches or tables that need to be adjusted to understand the new minimum speed settings...
So I am curious if anyone has tried to tune it, so that it is used only on the freeway above 65 MPH...
Thanks in advance
