OTS Maps Process Overview
1. At the top of the OTS Maps screen you should first set the OCT/RON toggle to the format
you are used to.
2. Next, if the Transmission selection is visible, a choice is
required (you will not be able to proceed past this screen
without choosing one). Tap it and you will see a popup
appear similar to this one. The available transmission
options specific to the vehicle you are flashing, so your
list may vary. This choice is remembered within MHD going forward.
3. Next, determine the correct Stage in the list per your vehicle’s modifications. You must
also own the Map Pack license for this Stage (or the Super License).
4. Now, in the Stage Fuel bar, tap the appropriate fuel type
that you will be using in the vehicle. If you do not see a
cer tain fuel (like full E85) available, it is likely because
the OEM fuel system would not suppor t it.
5. Next, tap the Stage button itself (anywhere outside the Stage Fuel bar works) to proceed
to the next screen, the MHD Flash screen.
6. Once at the MHD Flash screen, you can either flash
the map as-is, or tap Options to adjust the available
Flash Options (these are detailed in their respective
section below). There are three different flash lengths
you will see:
a. Full Write: this is the longest initial write, which
installs MHD for the first time. NOTE: a
battery charger is recommended for this! (if
not using MHD Black Wifi adapter)
b. Long Write: this is triggered when you are
adding or removing a flash option that
contains custom code / logic we have
developed at MHD. It is shorter than a full
write but depending on your connection, a
battery charger is recommended.
c. Map Write: this is a very short write, like changing from Stage 1 to Stage 2, etc.
