**MHD F+G Series Update V3.40**

Full OTS on the fly map switch and flex fuel release for all N55F and S55 cars.
Today marks the release of our OTS map switching and flex fuel feature for N55F and S55 powered cars.

You can now select 4 slots for the same stage to adjust fuel quality on the fly (pump gas and fixed ethanol like E30 map) as well as a power level in percent per map slot. If the flex fuel option is activated (and the required hardware installed) you can still setup 4 pump gas maps in order to quickly setup and change to the pump gas quality that is used at the time when the car is refilled without ethanol.

In addition to the octane selections, you can also use the slider to reduce the power that each map will make. This is very useful if you would like to make your own valet map or lower power map for cruising. The power can be reduced from 100% all the way down to 50% in 5% increments, this means if you put 50% into one map slot than this map only has half the power available it would usually make.

How to use map switching after the new update is installed:

1. Press and hold either the BC or SET/LIM button until the CEL blinks. The RPM gauge will show the selected map (1000 RPM = Map 1, 2000 RPM = Map 2 etc.)
2. Switch through maps by using the speed up and down rocker.
3. After selecting the map, press and hold the BC or SET/LIM button until the RPM gauge goes back to normal and CEL light stops blinking, the map is applied and also saved, it will not change until either another map is selected or the DME is reflashed with new settings. This means there is no need to select the right map after each engine start, it will use the last map selected.

We also added full E85 ST1 and ST2 maps for all S55(M2C, M3F80, M4F8x) powered cars. If you use the flex fuel hardware and flex fuel is activated, then you can fill up from pure pump gas all the way up to E85 and MHD will automatically adjust the map / power to suite your ethanol mix. This also applies to all N55F cars, as full E85 maps where already available.

Full Changelog:
- Added OTS MultiMap for F-series N55 and S55 (user selectable octane variant per slot, from 91 to E85; power limitation can be applied per slot to create your own valet map, cruise map, etc)
- Added OTS FlexFuel for F-series N55 and S55. (CANBUS based ECA hardware required)
- Added PT-CAN2 option for MHD ECA on some older cars
- Added M2 N55 full E85 map
- Added S55 full E85 stage 1/2 maps
- Updated Dorch S1/2 pump settings for F-series N55
- Updated ReFlex integration to include external wastegate contro

always log the multimap versions and make sure they are running correct. bm3 found out all kinds of weird variables after release. mhd may have the same issues.
