Re: Latest S7 Firmware
This Link - CLICK HERE is for version 1.653 of the S7 firmware.
PLEASE ENSURE LATEST SSUITE SOFTWARE IS IN USE BEFORE UPGRADING FIRMWARE!!!
Changes Since 1.650
* 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)
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).

Re: Latest S7 Firmware

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)
* detent solenoid output; follows detent switch
* new cm map use: rev limit max
* rpmFromVS reverts to rpmAvg if abs(driveRatioError)>x (with hysteresis)
* pit limit deactivation by timeout/distance clears latching pit switch
* configurable SENT low and high voltage thresholds and timeout
Set to SAE standard and 10ms as default.
* ability to start traction control reinstate timer from end of GC main, GC trailing, or GC ramp
* maintain traction control disable time better in GC so always correct after variable closed loop cut or early termination of open loop cut by end of request
* if(tcTRq>0) optionally add gear cut sevs to tc sevs inc tcIgnMax=gearCutIgnMax-tcIgnRtd
This allows TC to be enabled in conjunction with gear cut trail or ramp-in and shave an additional effect if needed.
* ability to start knock control reinstate timer from end of GC main, GC trailing, or GC ramp
* maintain knock control disable time better in GC so correct after variable closed loop cut or early termination of open loop cut by end of request
* delay downshifts if excessive driven wheel lock (negative wheelspin)

* 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.

* 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)

* torque control driver demand torque limit now disabled during gear blip trail
* new dbw limit item dbwLimitTrq; is beaten by blip (cf dbwLimitPit)

(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
