* VVT base duties a function of two configurable axes, default f(eot,eop)
We couldn't make it import the old settings perfectly no matter what, so for once this means MANUALLY COPYING ACROSS THE VALUES WHEN UPGRADING CALIBRATIONS.
* New item rpmAvgDT, which is rpmAvg rate of change per 1/100s
* rpmAvgDT available as cm axis choice
* Rev limit drive-by-wire gain, min, and max, become f(rpmAvgErr,rpmAvgDT)
This is to allow some derivative calibration on the rev limit drive-by-wire. Note that when the engine speeds drops below the lowest breakpoint, it use to ramp out according to the left-most gain cell value. There is now a whole left-most column (due to the addition of the rpmAvgDT axis) so it uses the TOP-LEFT cell (ie the one that would apply with the most-negative error and the most-negative derivative). This is commented in the F1 help notes.
* Engine coolant pressure trip thresholds are now mappable against engine speed as well as coolant temperature
* Preblip fuel cut severity, ignition cut severity, ignition retard configurable (single points)
This allows the engine-braking severity of the simple pre-blip to be adjusted in a similar (albeit less complex and configurable) way to the overrun fuel cutoff. Default numbers should match previous behaviour.
* Scaled tacho output becomes x rpm for y ms on calSelect change for driver indication (optional)
This allows the tacho drive to indicate cal switch position changes on a rev counter.
* Aircon PWM output
The existing on/off output stays the same but a second PWM output f(rpm,configurable) has been added. You can run the strategy with either one or both outputs configured.
* Idle speed target adder f(idleActiveTime,vehspd)
* Idle duty adder f(idleActiveTime,vehspd)
* Two user-configurable timers
These can be configured to time up to five minutes of a particular condition (two configurable items with configurable thresholds for each timer). The timers can then be used on the axes of configurable maps.
* Three sensor zeroing groups for user-defined sensors (Uxx sensors only - NOT Rxx sensors)
* User-defined sensor zeroing groups via action codes
You can assign which (if any) Uxx sensors are zeroed by which of the three new zeroing groups. This is for things like zeroing of user-defined ride-height sensors. Note that the zeroing does not know about the engineering-unit transformation (scaling and offset) defined for the sensor, so it zeroes to the raw zero value, not the engineering-unit zero value. If the user-definition offset has been set to zero (which it typically is) this makes no difference, but it's worth being aware of.
751 Update - * renamed mapMaxN to mapNMax
* removed mapxN default logging rates
* changed S7 CAN frame {dbw1Duty,dbw1Targ,egt1,egt2} to 100Hz
* pre-throttle-pressure sensors ptp1/2 including ptp1/2DT derivatives
* ptp1/2 available as cm axis choice
* ptp1/2DT available as cm axis choice
* option for key-on bap from ptp1/2
* calculate map1/ptp1 and map2/ptp2 as new items mapPtpRatio1/2
* add ptp1/2 faults to action codes
* option to target wastegate control manifold pressure against ptp1/2 instead of map1/2
* option to target wastegate control dbw limiting against ptp1/2 instead of map1/2

Option to select normalised manifold pressure as the primary load
There is a built in compensation table that computes multipliers based on act1/act2 from -30C to +140C. These multipliers can be seen in map1NMlt/map2NMlt. The normalised map1/map2 are then computed as map1N/map2N. They will be between 0.75x and 1.25x the un-normalised values. There are also map1NDT/map2NDT (mirroring map1DT/map2DT) and map1NFault/map2NFault, and also a mapMaxN. If you select the new primary load option for normalised manifold pressure (instead of manifold pressure) a whole bunch of things that are currently mapped against map1/map2/mapMax become mapped against map1N/map2N/mapMaxN. These should all be labelled properly in SCal and include main fuelling and ignition and things like fuel angle and blend maps, lambda targets, torque estimation tables and so on. If you do not set the fuelMltAct/ignAddAct tables to 1.000/0.000 you will get a warning (but it won't actually stop you). There are lots of things that may come after this. Ways to target boost pressure from normalised values (consistent torque delivery) but with absolute pressure limitations still (for rules compliance and to protect pipes etc) for example.
The one big thing to note (apart from that we need to carefully test in both the new and original modes) is that you need to set breakpoints and calibrate your fuel and ignition maps to go beyond what you might usually expect, because map1N/map2N can be up to 25% greater than map1/map2 if it gets really cold, and you don't want to go lean or have too much ignition timing. Calibrators need to understand this properly, and NOT use the feature if they are unsure about it.
3) Alternate full-bridge drive mode option
For S8 and S12 the Full bridge drive Frequency will be changed to a lower range to help with motor winding disturbance from engine harmonics
4) Optional thirds-based gear linearisation hysteresis
Until now we linearised gearV (actually gearVF) to gear based on the mid-points of the in-gear voltages. This could generate a lot of changes of value very quickly if the barrel wobbled about between gears, which was especially inappropriate in some situations. For a special project, we switched to changing "gear" only when 2/3 of the way to the new voltage, giving both hysteresis and stability when in a deliberate false neutral. This is likely good for almost any project, so I have defaulted this to ON after a calibration upgrade.
5) Option to disable calibration override uses budgeting
This allows you to use time budgeting only.
6) Drive-by-wire can be limited by overrun fuel cut - see the new tables and "dbwLimitOrfc"
Also this limit, or torque reductions from overrun fuel cut (ONLY) do not disable cruise control, but do prevent enabling it
7) Gear cut/blip configurable maps
CM for gear cut dog kick time multiplier
CM for gear cut closed loop main max time multiplier
CM for gear cut closed loop retry max time multiplier
CM for gear blip dog prep time multiplier
8) Configurable number of closed loop gear cut dog kicks (main kick retry kick retry kick...)
9) Dummy input 'pin' for use for gear-voltage-from-CAN overriding (used with Megaline CAN)
10) Fuel pressure trip now looks at fpp as well as other pressures (default threshold -1000)
11) Sensor zeroing for clutch position via ethernet comms and action codes
12) Sensor zeroing for clutch paddle positions via ethernet comms and action codes
13) Enable/disable sensor zeroing by group in the calibration
This allows competitors in a series to be locked out from anything they shouldn't be zeroing - eg wastegate position, even if their user ID allows zeroing "in principle".
14) Datastream scaled values for ppsFinal and tpsMax
15) Option for low oil pressure light on off thresholds to become margins above eop1Trip
16) On load/off load overrev markers in datalogging
Whenever the logbook count changes, a text marker is dropped if logging is active.
17) Tacho In function now usable to measure clutch slip (for example)
The function is now renamable, called Engine Speed Input and defaults to [Tacho]. There is a new tacho_rpmIn item. You can define teeth per reading separately from teeth per rev. If enabled at the same time as engine control (which used to be an error) it does not set rpm (but still does if engine control is disabled).
18) In-range switch thresholds include their endpoints
19) The code knows the new PDUXB output states for proper naming in datalogging.
20) New choices for configurable map axes
cruiseVehSpeedTarget available as cm axis
cruiseVehSpeedError available as cm axis
cruiseRpmTarg available as cm axis
cruiseRpmError available as cm axis
cruisePps available as cm axis
cruisePpsBase available as cm axis
tbvDuty available as cm axis
fuelPump1Duty available as cm map axis
tacho_rpmIn available as cm axis
21) Fixed Syvecs datastream changes as requested
Change S7 frame {rpm,ppsFinal,tpsMax,adip1Duty} to {rpm,dsPpsFinal,dsTpsMax,adip1Duty}
Change S7 frame {carCode05,carCode06,atSelect,spare} to 20Hz
Added S7 frame 1Hz 625h {IIE_logDistance1H_U,IIE_logDistance1L_U,IIE_logRunTimeH_U,IIE_logRunTimeL_U}
