Latest S12 Firmware

Post by Ryan.g » Mon Mar 10, 2014 9:54 pm

This Link is for version 1.437.1 of the S12 firmware.

PLEASE ENSURE LATEST SSUITE SOFTWARE IS IN USE BEFORE UPGRADING FIRMWARE!!!

viewtopic.php?f=8&t=122

Changes from 1.410

* Full Automatic Gearbox control for Manumatic and Semi-automatic types..... Electrohydraulic and Dual-clutch coming later this year

* Alternate Secondary Injection Time

*Rev Limiter Update. You used to be able to choose between fuel cut or ignition cut. Now the limiter is always fuel cut if you stay in it long enough. You have the option to start with an ignition cut with absolute ignition timing limit. These ignition functions are active for a mapped 'active' duration from the point where you first enter the limiter. Going in and out of the limiter very quickly does not reset this timer. You have to go out of the limiter completely for the re-enable time before you can have ignition cuts again. After the timeout you get the fuel cut setting instead. If you don't want any ignition phase, set the active time to 0. Limp mode and downchange blip limiting goes straight to fuel cuts unless they don't reduce the normal rev limiter.

* VVT open loop has gained engine speed hysteresis

* Idle control now has a base fuel adder - only useful if you have a separate air bypass valve not DBW.


Enjoy

This Link is for version 1.599 of the S12 firmware.

PLEASE ENSURE LATEST SSUITE SOFTWARE IS IN USE BEFORE UPGRADING FIRMWARE!!!

Changes since 1.590
* Double-downchange blip strategy becomes multi-change and allows more than one target retune. This is to support integration with OEM gearbox controllers that can downchange many gears for one request.
* Option for latched pit switch to be on or off or as remembered at power on.
* Option to always log while engine turning (syncState is anything apart from NONE) regardless of normal logging thresholds.
* Faster logging start/stop evaluation (was 5Hz now 10Hz).
* Maximum primary / secondary fuel split in direct+port injection mode calibratable.
* Calibratable end-of-ramp for gear cut absolute ignition maximum.
* New configurable map use - scaled tacho output multiplier.
* Reduced default dbw final duties to 25%/75%. This is fine for most new builds and less demanding of wiring.
* Wastegate control minimum manifold pressure target is now calibratable as a function of alsSelect.
* Corrected displayed units of fuel split rate of change limit from degrees/cylinder to percent/cylinder (cosmetic effect only).
* Allow rpmDTR negative on configurable map axes.
* Fixed gear system pressure leak detection prime time (this feature was broken by a change in 1.556.2.1).
* Logging of gspControl now shows the relief valve activation period.
* PDU output state display now includes the alarm state from 2-12-x PDU code releases (due shortly).
* LR GPS-AG50 and GPS-A10 internal temperatures.
* Default ECP trip in new calibrations is now OFF. We have agreed ECP is uncommon enough that using ON is too disruptive for upgraders.
* Allow brake pressure scalings greater than 1 in driver brake pressure determination. This makes it simpler to match front and rear brake pressures specifically when setting up bpd as max of bpf and bpr to feed the brake and throttle safety trip function.
* Added manifold pressure option to tps/bpd trip. This allows an additional safety catch for un-demanded high power - in particular for single throttle forced induction engines which are calibrated speed/density.
* Option to clip standard wastegate strategy manifold pressure target limit to launch control manifold pressure target during launch.
* Prevent wastegate control base learning function from continuing to increase/decrease when output is already at 100%/0%.
* Improved user gear position faulting help notes.

This Link is for version 1.620 of the S12 firmware.

PLEASE ENSURE LATEST SSUITE SOFTWARE IS IN USE BEFORE UPGRADING FIRMWARE!!!

Changes since 1.599
ACTION CODING SYSTEM
Primarily aimed at endurance racing, this system allows the driver to request selected actions in response to team instruction, for example informing the ECU that a particular sensor has failed (thus forcing an A/B switchover for example) where the ECU has not detected the failure automatically. There is help in the calibration but, in essence, Set and Clear codes 1 through 99 are received via CAN, and mapped in the calibration to specific actions.
* Raw action Set and Clear codes are received from CAN A or B channels
* Monitoring items actionCodeSetAck/actionCodeClrAck are used to acknowledge last accepted codes
* Action is taken if received code acceptable and differs from last received code
* Received code <=0 is always no action
* Received code is passed through a mapping table in the calibration to choose the actual action
* Relevant set actions are remembered and reapplied after ECU reset (for example sensor faulting)
* Clear-All action applies all clear actions and clears all persistence
* Action persistence memory is cleared on code programming
* Action persistence memory is retained on calibration programming unless the mapping table is changed
* Monitoring item actionCodeActive cycles through the active persistent codes

SENSORS
* A/B redundant wheel speeds with swapover on sensor failure or sensor switch
* Action codes to set/reset wheel speed sensor faults
* Action codes to set/reset faults on all analogue voltage sensors

* Selectable default LR GPS speed (0 or maximum)
* Selectable default Basic GPS speed (0 or maximum)
* LR GPS date/time logging items
* Megaline E-Shift actuation frame transmit

PIT CREW EXTERNAL PEDAL SUPPORT
Where deemed acceptable from a safety point of view, this allows a hand-held trigger external to the car to be used to control the drive-by-wire pedal demand for warmup control and shift checks.
* Value shown in ppsExternal; acts as jacker to ppsFinal
* Enabled via the gearbox control select switch (gcSelect)
* Single analogue input 5V only
* Two point voltage to pedal linearisation (0% and 100%)
* Single point maximum authorised pedal value
* High and low engine kill voltages

SAFETY
* Option to activate fuel pressure trip immediately on dip1Fault/dip2Fault
* Option to ignore engine speed on downchange from 1 without clutch when pit limit active
* Above option also ignores vehicle speed on downchange from 1 when pit limit active
* Linear rate of increase limit on oil pressure trip threshold

INJECTION
* More efficient (E) injector drive setting options (GDI4)
* Default GDI power level now STANDARD(E) (GDI4)
* Support direct injection pump control on non-ignition outputs if asynchronous
* Fuel Pump 1 PWM y axis configurable
* Instantaneous per-cylinder post-cut-enrichment

LAUNCH
* Launch re-enable by vehicleSpeed disabled if vehSpdFault
* Launch re-enable by vehicleSpeed disabled above calibratable gear
* Launch exit by calibratable gear reached
* Option to exit launch stage by drivenSpeed
* Option to use brake light for launch switch
* Option to use rpmAvg instead of rpm

TRACTION CONTROL
* wheelSpinFlt used by traction control rather than wheelSpin
* filtering of y axis in traction control spin target lookup
* vehicle speed lookups now use filtered vehicle speed

DBW
* Asymmetric DBW pedal demand filter - optionally different in rising and falling directions

ALS
* ALS duty ppsFinal y axis - allows aggressive DBW bypass to be blended down as pedal increases from closed
* alsSelectSwitch to alsSelect mapping by lap distance
* Option to limit bypass duty to blip duty for more consistent blips when running very aggressive ALS

LIMITERS
* Pit/FCY entry speed guards are now relative to the speed target not absolute values
* Pit/FCY vehicle speed and engine speed targets are now f(pitSelect) not f(calSelect)
* Optional change light flash on speed goal attained for Pit/FCY limits
* DBW rev limit function (similar to pit limit DBW function)
* rpmDtr axis added to rev limiter torque reduction tables

CONFIGURABLE MAPS
* New CM map use : fuel pump 1 base duty add

IMPORTANT!!!

*** MINIMUM BOOT CODE VERSION IS NOW 1.68 FOR THE FOLLOWING FIRMWARE TO WORK ***

STARTING WITH THIS RELEASE, THE MINIMUM BOOT CODE VERSION REQUIRED IN ANY S8 OR S12 IS 1.68.
THIS CODE WILL REFUSE TO LOAD INTO ANY ECU WITH BOOT CODE OLDER THAN THIS VERSION.

As you are aware we have always tried hard to make new firmware compatible with older ECUs and are generally proud of our record in doing so. This point was anticipated and boot code 1.68 was released in early 2015 in preparation. This code should therefore be usable in ECUs up to approximately three years old.

This Link is for version 1.653 of the S12 firmware.

PLEASE ENSURE LATEST SSUITE SOFTWARE IS IN USE BEFORE UPGRADING FIRMWARE!!!

Changes since 1.620


* Minimum boot code version now 1.68
* Closed loop PWM 01 (proportional+integral) with selectable target and axes (via the V/C menu)
* New CM map use : closed loop pwm duty adder
* 5 fixed instrumentation/gauge pwms replaced with 12 reconfigurable ones
* Traction control spin target y axis filtering duration maximum increased to 1 second
* Option to use rpmAvg instead of rpm in ALS
* Maximum gear setting for pit switch latching
* Alternate vehicle speed measure selectable during pit and full course yellow limiters
* Engine speed from vehicle speed and drive ratio monitoring item (rpmFromVS)
* output type select for lambda heater to allow high side drive using HB outputs
* check for and object to inverted voltage threshold calibration on wheel speed, turbo speed, pwm pedal position, fuel composition
* idleTarget available as cm map axis
* ignFinalPri1/2 available as cm map axis
* added dash (-) and 'illegal' alphabet characters to available vin tx characters

* sensor filter constants applied to x:can receive assignments
* logging bandwidth expanded by the equivalent of 40 additional 100Hz channels
* rpmFromVS available as cm map axis
* traction control linear decay now function f(tcSelect,gear)
* traction control recursive decay now function f(tcSelect,gear)
* new cm map use: pit speed adder
* new cm map use: fcy speed adder
* pitSpeedTarget monitoring item
* lmp pit/fcy limit maximum ignition advance tables
* allow rpmFromVS to be used as x axis for ALS
* increased number of wgp-based wastegate control maximum manifold pressure tables
* mean ignition angle monitoring items ignFinalPriMean/ignFinalSecMean
* pduA/B/C can receive now supports 48 channels for PDUX4
* standard wastegate control map target limit now f(rpm)
* LR GPS A10V2 can receive option (legacy A10 sent speed in knots rather than m/s)
* fuel pump-out switch
* fuel pump 1 pump out duty
* fuel pump 2/3 pump out options
* fuel pump out optionally disables fuel pressure trip when engine stopped
* optional run mode protection on all variable intake outputs
* variable intake switchover deactivation delay
* lean-trip threshold now 3D with configurable y axis
* starter enable output
* skyline sync pattern min and max tooth count
* increased number of base and target map rpm breakpoints in wgp-based strategy
* cal override A and B inputs (especially useful when in latching mode)
* increased acceleration sensor ranges (+/-25G rather than +/-10G)
* output type low-side/half-bridge/full-bridge for wastegate control outputs
* closed loop pwm 01 integrator rate configurable
* als driver demand addition f(wheelSpin,bpd) (for negative wheelSpin)
* als driver demand addition multiplier f(tcSelect)
* als driver demand addition decay rates (linear and recursive) f(tcSelect)

As you may know, usually ALS pushes on. However high-end RWD circuit cars have a tendency to rear wheel lock in ALS under heavy downforce-assisted braking. These changes allow for a form of negative traction control where ALS torque reduction can be removed to aid in that situation.

* simple rpmDTR stabilisation for launch

Without changing any other values, try creeping the new single-point stabilisation value up towards 1 (in stages). As long as you have a torque gradient against rpm error in the torque maps, this should somewhat stabilise the engine speed control by using a fraction of rpmDTR to affect the torque control lookup.

* new cm map use: change light threshold adder

* 5-point eot axis for eop start prevention

This should make the start eop1 limitation much more useful since oil viscosity can now be accounted for. Shares breakpoints with oil pressure trip eot axis for obvious reasons.

* closed-loop idle ignition authority multiplier with linear roi/rod

Hopefully obvious, especially if you log the new idleIgnAuth value, which goes from 0% to 100% when closed-loop idle is entered, and from whatever to 0% when it is exited. ignAddIdle is multiplied by this, resulting in smoothly increasing authority after entering idle, smooth decay on exit, and hopefully relatively smooth re-entry as well.

* idle duty integral min/max now f(driveRatioError)
* set driveRatioError 25000 not 0 when drivenSpeed 0 or gear unknown or neutral

These together should allow you to prevent idle duty integral windup when decelerating off-throttle in gear. The idea is to set the min/max to zero at driveRatioError of zero and fade it up to your normal min max values over maybe 50 to 100 positive driveRatioError. You should also fade up at negative driveRatioError, which is clutch-depressed and off-throttle while rolling (engine slower than expected).

PLEASE ENSURE LATEST SSUITE SOFTWARE IS IN USE BEFORE UPGRADING FIRMWARE!!!

Changes Since 1.653

* rev limit fuel sev CM and dbw disable on Gearcut option
* rev limit fuel sev table under ignition control to help lower egts
* slight change to how traction control trq can add in ALS or GC trq - should be immaterial in almost all circumstances
* detent switch turn on vehicle speed maximum (only applies to physical switch not cal-switch detent yet)
