= s7 : 662h frame add Vbat, pitSwitch, pitLimitActive

(in 680)
* new cm map use: vvtIn/ExBaseDutyMlt (in particular for ect- or eot-based adjustment)
* H/L U16 monitoring items for total logbook distance to can stream to dash
* H/L U16 monitoring items for total logbook run time to can stream to dash
* H/L U16 monitoring items for total logbook on load time to can stream to dash
* VVT disable run time a function of ect
* option to mark VVT as failed (causing limp mode) while disabled by run time or lack of 720 sync
* wgp-based strategy map drop for prp/turbo fail now has 'never' option
* new cm map use: compute only (raw value; map marked as in use but not connected to any strategy)
* all cm map outputs directly available as cm map axis choices
* wgp adder cm map use range doubled to allow forcing wgp target to 0% regardless of pid action
* new cm map use: fuel cut severity (always computed but only effective in run mode)
* filtered final pedal position delta, ppsFinalDT
* ppsFinalDT available as cm axis
* new cm map use: n2oDutyMlt
* n2oFinal available as cm axis

(in 682)
* option to run lambda heater whenever engineEnable OK (default off)
* clip incoming slave voltages to prevent 5.005V causing trouble
* s7 : ign 11 and ign 12 plus slaving to fuel outputs for sync di pump

(in 687)
* idle speed enable max rpm error cell raised from 1000 to 10000
* monitoring items wgMapMaxMltAct1/2 for existing act correction to map max targets
* option to clip direct injection by time as well as fraction of rev (with popup warning) (di+port mode only)
* option to trip fp only when runtime>=x (with popup warning should only be non-zero for mechanical fuel pumps)
* ability to select bus used for master/slave links 1 and 2 (cannot yet combine with eachother or other comms)
* syvecs slave 1 extended timeouts on s8/s12 as well as s7
* syvecs slave 1 additional fixed transmit stream on s8/s12 as well as s7
* syvecs fixed can stream serial echo optional on s8/s12 as well as s7
* engTrqEstDmdFraction Monitoring item
* new cm map - DBW Multiplier
* rs232 25hz transmit option
* trip enable run time for Fuel pressure trip

(in 688)
- fixed display name typo in clPwm01Targ and clPwm01Err
- make atDstGear a monitoring item
- auto trans option to trigger gear blip request from start through power state
- gear blip strategy now active (for trigger from syvecs can or auto trans) if auto trans enabled
- syvecs can rx does not drive blip request if autotrans active and controlling blip requests
- auto trans separate N>D and N>R safety thresholds
- auto trans shift start/end/ramp duties f(configurable item) (full off/on still single point)
- new cm map use : auto trans lock pressure duty multiplier
- auto trans lock duty always updated (except during shift)


(in 690)
* ten more configurable maps cm211..215 and cm311..315
* auto trans option to retain lockup clutch through downshift
* auto trans gear blip request start state calibration
* set rpmFromVS to rpmAvg if vehicle speed fault
* clip rpmFromVS to minMlt..maxMlt x rpmAvg
* option in paddle down shift to protect by rpmFromVS rather than rpmAvg

(in 693)
* VVT closed-loop failure action - choice of disabled or open-loop (defaults to disabled)
* VVT option to retry closed-loop after failure if engine restarted (required power cycle previously)
* VVT open loop switchover default values now 25000rpm

In the past the code defaulted to open-loop operation if closed-loop operation failed. This was rarely well calibrated and rarely appropriate. We have therefore allowed VVT to be completely disabled in this circumstance (and typically a limp mode will be used). The previous behaviour is available if truly desired.

* the high engine coolant pressure trip threshold is now calibratable against ectMax
* there is a new monitoring item for this threshold, ecpTripHigh

* orfc fuel cuts f(rpm) (default 100%)
* orfc ign rtd f(rpm) (default 0)

Overrun fuel cutoff can now be mapped less aggressively and against engine speed, and may include ignition retard.

PLEASE ENSURE LATEST SSUITE SOFTWARE IS IN USE BEFORE UPGRADING FIRMWARE!!! http://www.syvecs.com/forum/viewtopic.php?f=8&t=122

Changes Since 1.693

Follow the firmware update guide here - https://www.youtube.com/watch?v=Pi1pp-XbQqw&t=331s

(in 694)
* Improved overrun fuel cutoff help notes
* fuelMltOrfcEnd now 1.000 during orfc (matters since 100% fuel cut made possible in 693)
* idle target CM range increases from +1000 to +2500
* gps fault invoked by mappable quality < x
* added vehicle speed fault limp cause (new vehSpdLimp monitoring item)
* limp mode on failed vehicle speed is optional
* optional vehicle speed forced fail when gps reverts to wheel speeds

(in 696)
* limp mode on failed vehicle speed now defaults to NO (on upgrade from <694) to avoid limp when no wheel speeds configured
* new monitoring item dbwTargMax - higher of dbw1Targ and dbw2Targ
* dbwTargMax available as cm axis
* removed torque control driver demand blend out
* new cm map use: torque control driver demand adder
* option to disable torque control driver demand limit when closed loop idle active (defaults to NO)
* renamed torque control Driver Demand Torque Limit to Maximum Driver Demand Torque to avoid confusion between map and function
* torque control driver demand torque limit now disabled during gear blip trail
* new dbw limit item dbwLimitTrq; is beaten by blip (cf dbwLimitPit)
* torque control dbwLimitTrq integrator f(engTrqEstDmdMargin,dbwTargMax) max 100% min dbwTargIdle

(in 699)
* external torque conversion output maps, used to keep OEM TCM's happy by keeping torque values within OEM Limits but allows internal torque calculations to be uneffected.
*new monitoring items engTrqEstFrictionExt, engTrqEstOutputExt, engTrqEstOutputPotExt, engTrqDmdPpsExt (these are the outputs of the Torque S Curve, recommend to be sent in datastreams - Custom Can Transmit for OEM setups
*lambda heater pwm frequency adjustable

702

* trqFuelSev available as cm axis choice
* trqIgnSev available as cm axis choice
* rev limit DBW limit now beats gear blip DBW jacking
* activation engine speed error threshold for rev limit DBW limit (so can defer activation until rev limit reached)
* add check for revCutActive to lean lambda service
* changed detection of engine stopped for clutch protection of paddle shifts in pit from runMode!=run to rpm==0
* initial help notes on direct injection pump control operation
* remove Syvecs hard-coded RS232 stream
* replaced RS232 can echo with RS232 Generic Transmit (up to 20 frames; mappable content)

705

* change launchInStage to launchState in fixed syvecs CAN stream
* calculate map1/ipp1 and map2/ipp2 as new items mapIppRatio1 and mapIppRatio2
* high load timer decay rate and maximum value

706

* option to disable fuel pump when engine enable switch off
* new item launchStateX (extended/combined launchState and launchInStage)
* change launchState to launchStateX in fixed syvecs CAN stream
launchState should read identically to before. launchStateX should read the same as the old except in stage, where it has a different value (please log both to compare):
launchState : 0=OFF 1=ON 2=CLEARING 100=DISABLED
launchStateX : 0=OFF 1=ON 2=CLEARING 50=STAGE 100=DISABLED


708

* prevent fpoSwitch turning on while engine is running
* cancel fpoSwitch if pump out cancelled
* remove detent switch vehicle speed protection (caused some confusion and downshift from N protection better anyway)
* disable up/down shift inputs for 250ms after device turn on (in case of runt pulses from other hardware powering up)
* auto trans solenoid outputs full off duty modifier (as existing full on duty modifier)

We then have

709

* wheel speed linearisation speed=f(speed) for tyre growth (different front/rear curves)
* raw (nominal) wheel speed monitoring items
* use raw (non-latched / cancelled) override switch states for pedal learning validation

710

* closed loop idle disable by drive ratio error
* closed loop idle base duty learning

711

* help on value of 7 in manual cam checklists
* add cal offset to logOnLoadTime / logOnLoadTimeL / logOnLoadTimeH
* add cal offset to logRunTime / logRunTimeL / logRunTimeH
* new monitoring item ppsClosed (works from ppsFinal)
* preblip no longer forces orfc but works through gear blip torque reduction
* significant overrun fuel cutoff changes
- option to enable by ppsClosed rather than by tpsClosed
- disabled by gear blip even if pps used for activation
- new monitoring item orfcPct; ramps in and out when orfc engaged / disengaged
- orfc ignition retard applied according to orfcPct; fuel cuts applied when orfcPct is 100%
- NOTE THAT ORFC FUEL REINSTATE MULTIPLIER IS LOST; ORFC IGNITION CUT OPTION IS LOST
* update ECU with new list of output statuses from 2-20-x PDUX firmware
* changed yaw to second transmission of rpm in default Syvecs rs232 stream content
