MoTeC M4/M48 Software Release Notes

Version 6.20D Release


Including

ECU hex 6.20A 7 May 2003

EMP 6.20 22 May 2003

GETLOG 6.14 20 March 2003

ENABLE 7.03 20 March 2003

SEND 6.13 20 March 2003

MPI 19 May 2003

UPGRADE 6.21 19 May 2003

EMP_VDD 1.06 7 May 2003

First Windows Installation


Windows based installer to make software installation easier

MDD Support


The above changes to telemetry data set 5 allow the M4/48 to communicate with an MDD V1.12 or higher. The MDD is a display module that can be used to display ECU information without needing a laptop

Increased maximum Injector pulse width (IJPU) value


The injector scaling parameter IJPU was limited to 25ms. This has been increased to 40ms. This helps with both primary/secondary injection and engines that have peak torque at relatively low RPM

Changed minimum injector off time to 0.5msec


This allows slightly more fuel to be delivered from undersized injectors. The MAX DUTY diagnostic will still be triggered when the off time is <= 1ms.

For this to be effective in angle modes (missing / additional teeth) at least 36 crank teeth are required.

Note that the maximum fuel pulse width is:

Multi-tooth modes = 60mSec

Missing/additional tooth modes = 50mSec

Modified Gear Change Ignition cut (GIC) function


The cut is no longer aborted if the cut signal is removed.

No longer check TP & RPM conditions while cutting in mode 2 & 3

Added mode 3 - cut while cut signal active. This mode is used if a gearbox controller needs to control the ignition cut duration.

Delay of -10 means do not cut in this gear - ignores the cut signal in all modes. Useful when the driver tries to change into 6th with a 5 speed gearbox.

Added Engine temp (ET) calibration to use auxV input


Setting ET sensor cal to -2 will use the AUXV pin as ET input. Uses ET user

cal. This mode is required for the ECU to share an ET sensor with an OEM ECU.

Note: AUXV Channel will work as normal on auxV input but should be ignored

8 cylinder 2 stroke now supported (M48 only)

Change to “Lambda was”


Changed “Lambda was” low limit to 0.60 (was 0.75)

Fix to Ignition Gear Comp


Corrected Ignition gear comp. Compensation value was incorrect while being adjusted online

EMP Enhancements


Added help detailing which features are available in Advanced Tuning

Shows a message if the firmware is older than the version on disk

Shows the hex version as well as the EMP version on the main screen

Added detection for incompatible special hex versions

Corrected help: Standard Tuning for Fuel & Ign now has 40 x 21 sites

Changed operation of F5,F6 & F8 so that they are always active irrespective of the selected mode, and go to the associated screen rather than toggling between Fuel and the associated screen. (This is consistent with M800)

Added graphing of Site Setup

Added interpolation of Site Setup

Added help for calibration of MAF on Digital Input

Fuel ET comp limited to 0 (was -100)

Added help to auxV Calibration to say that the 690kPa cal is for the Gauge sensor

Removed help on 690KPa cal for MAP sensor because it is a Gauge calibration which is not appropriate for MAP

If the ECU was enabled after sending the Hex EMP would ask for a password and the only workaround was to enter the backdoor password. This has been fixed.

"SUU Connected" message changed to "SUU Connected or ECU not Enabled"

Added help for the Diagnostics Errors to the Main Menu Help item so that the Diag Errors help can be accessed off line.

Fixed a bug which could cause timeouts when sending a file with some USB serial ports

Change to Telemetry data set


Changed auxiliary output duty cycle scaling in telem sets 5,6&7 so the values would display correctly on the ADL and in Telemetry monitor. Previously the value was displayed 10 times smaller.

Changes to USB serial port support for Win 2000 and XP


Extended timeouts in all applications to make USB comms robust on XP.

Enhancements to make EMP more responsive to keystrokes when offline. Win 2000 and XP comms driver could cause problems with old software versions if new and old software had been used in the same session. This has been resolved.

Work around unusual behavior with some USB serial ports. This fixed a problem where utilities such as getlog could not communicate with the ECU in some cases

MPI menu for serial port selection


MPI now allows the serial port to be selected via a menu (F5). The selected value is remembered

MPI message changed


OLD MESSAGE
" Loading Program - Please Wait "

LATEST MESSAGE
"Loading Program..."
"or the selected program is running,"
"close it to return to this menu"

Upgrade - Changed error reporting


Upgrade could report “Unknown Windows Version” on some old windows versions. This has been fixed

Version 6.13D Release


Including

ECU hex 6.13 17 Oct 2001

EMP 6.15 22 Nov 2001

Faster Comms and USB Serial Port Support


Faster Comms driver for NT4, Win2000, WinXP included. This works with both standard and USB serial ports. Added support for COM3 to COM9 on command line to suit USB

Utility programs GETLOG, ENABLE, UPGRADE now use new comms driver

Note: The use of USB serial ports is not supported for Win95/98/ME.

Version V6.13 Release


Including

M4 hex 6.13 17/10/01

EMP 6.14 24/10/01

Password Bug


The software has been upgraded to solve a problem in which a user could lock themselves out of the ECU by setting one of a small number of passwords. Note that the ECU would continue to function, but that the user would not be able to enter the adjust screens. The latest installation removes this possibility so that any combination of alphanumeric characters can be used as a password

Crank Reference Teeth


128 and 135 teeth added

Eff2 Calc Method 6 - auxV


AuxV now processed correctly when used as input to Eff2.

Mode 6 is for a voltage output mass flow meter connected to the auxV input. It undergoes a mass flow calculation from grams/sec to milligrams/cyl/cycle.

REF cranking voltages


Changes to improve reading of lower voltage Ref signals during cranking (M4 only)

Install Update


Changes to make serial communications reliable on new PCs running Windows 98SE/ME

Log set 3 Bug fix


Log set 3 generated corrupt logged data - this has been fixed

File Encryption


The M4 and M48 now support encryption of the config file. This allows the ECU to be password protected, but files encrypted for that ECU may be sent to the ECU by the end user.

Overrun Boost Enhancement


Help updated

ORB Maximum Time


0 now disables the timeout

EMP Telemetry


EMP now has the capability to send telemetry out a second serial port, to allow display of ECU data on an ADL while tuning the ECU

The UPGRADE program replaces the SEND and CONVERT programs.

There are two menu items in the upgrade program as follows :

UPGRADE ECU

Allows the ECU to be upgraded in one simple step.

Upgrade sends the new ECU Control Software to the ECU and converts the ECU calibration data so that it is compatible with the new Control Software.

It is not essential to have the old version software to perform the upgrade, however should it be necessary to revert the ECU to the old version the old version software will be required.

As a safety measure the original ECU calibration data is stored in the directory for the old software with a comment of "Upgrade Backup : Converted to Vx.x".

CONVERT FILES

Performs the same function as the old Convert Program.

Version 3.9

Quick Lambda from Ignition Screen


Quick Lambda may now be used from the Ignition screen. This allows both Fuel and Ignition to be adjusted from the one screen.

Frequency Type Air Flow Meters


Load and Efficiency point calculation methods now include modes for frequency type Air Flow meters.

Traction Control - Gear Position


Traction Control may be performed based on one ground speed sensor and the current gear position.

Set the Traction Control Slip Source parameter to mode 5.

The gear system should be setup to measure the gear position using a voltage from the Aux Temp or Aux Volt Input (usually from a potentiometer).

The Gear ratios should be set to allow calculation of the driven wheel speed from the engine RPM.

Slip Warning


An Auxiliary Output may activate a warning light when the wheel slip exceeds a definable limit. (Auxiliary Output mode 112)

Traction Control Disable


A Digital Input may be used to disable Traction Control. Useful if a bad sensor causes incorrect operation. (Digital Input mode 14)

Wide Band Lambda Control - Site Disable


Wide Band Lambda control may now be disabled at any site by setting the site to zero.

Aux Volt Thermo Couple Calibration


The Auxiliary Voltage Input may now be calibrated to suit a thermo couple amplifier.

Narrow Tooth - Multi Tooth


The Ford Narrow Tooth REF Mode now supports multi tooth pickups ie. more than one tooth per TDC.

Hi / Lo Duty Cycle

Direct Entry + Mathematics


Values may be directly entered using the number keys.

Mathematical operations may also be performed by using the +, -, * or / keys after the number.

"Lambda Was" Direct Entry


The current Lambda value may be directly entered by pressing the L key. This will adjust the Fuel Table value to give the desired lambda as indicated by the Lambda Control Table.

This is useful when making adjustments from logged data, it is not recommended for Dyno Tuning as an incorrect entry could cause engine damage.

"Lambda Was" Display


The Fuel Main Table now shows a "Lambda Was" value at the top right of the table. This gives an alternative method of making adjustments from the logged data by simply using the PgUp and PgDn keys as normal.

Traction Control - Launch Control


A simple (but effective) method of launch control is now available which allows the RPM to be limited based on ground speed.

Ford Narrow Tooth Pickups


The Ford Narrow Tooth pickup system is now supported. (REF/SYNC Modes 181 and 183)

Mitsubishi 360 Slot Optical


New REF/ SYNC modes 101 and 103 have been added to cater for the Mitsubishi 360 Optical pickup which is a slight variant on the Nissan 360 Optical pickup.

Version 3.3

Traction Control Improved


Traction Control now has a Throttle dependant table to define the desired amount of slip at various throttle positions.

The amount of slip is now defined in speed units (eg. km/hr) rather than percent. (Percent slip may still be selected if necessary)

Launch RPM Limiting is now incorporated in the Traction Control Function. The Launch RPM is activated when the vehicle speed is zero and the throttle is greater than 80%. This allows a lower RPM Limit to be set during launch and during the transition between launch and full traction control.

Shift Light - Gear Dependant


A new Shift Light mode has been added to the Auxiliary Output functions that allows the light to be activated at a different RPM for each gear.

Dual RPM - RPM Rise Rate


The Dual RPM Digital Input modes now have a RPM Rise rate parameter to limit the rate of rise of RPM when changing from the lower RPM Limit to the normal RPM Limit.

Lambda Sensor Calibration Table


The Lambda Sensor may be calibrated using a calibration table.

Useful for wide band measurement systems that produce a voltage output.

Version 3.2

Set All Values


All values in a table may be set to the value of the current site (Select from the Function Menu)

Ignition Cut Rev Limiting


Previously Ignition Cut Rev Limiting was not fully operational for REF/SYNC Modes 21 to 83.

Ignition cut rev limiting now works with these modes as long as the Ignition system does not respond to a 10usec pulse. Most Ignition systems do not respond to a 10usec pulse but some do eg. Mercury CDI.

Mass Air Flow - Aux Volt Input


The Mass Air Flow sensor may be connected to the Aux Volt Input.

Version 3.1

Hi / Lo Injection


May be configured to individually operate separate Hi / Lo Injectors.

M4 ECU 2 cylinders (or less) (Including 2 rotor rotaries)

M4-8 ECU 4 cylinders (or Less)

The balance between high and low injectors may be adjusted for various RPM and Load points..

The Injection timing for the secondary injectors may be adjusted separately for various RPM and Load points.

The High and low injectors may have different flow rates but must have the same current requirement.

Firing Order


The Firing Order may be entered without having to set the Top Dead Centres.

Adjustments may be made from the Graph screen

Sequential Option FREE (M4-STD ECU)


Sequential Option will be enabled free on M4-STD ECU.

It will be more expensive to upgrade an M4-2DF to the same options level.

If an older M4-STD ECU (Rev A or Rev B) is upgraded to V3.0 it will get the Sequential option free if it has not already been enabled.

Logging Free Time


6 Hrs free logging time, Indicated by an * next to the LOGGING option on the E.M.P. main screen.

Lambda Free Time


6 Hrs free Lambda time, Indicated by an * next to the LAMBDA option on the E.M.P. main screen.

Dual Edge REF/SYNC Mode (Rev B ECUs Only)


Dual Edge REF / SYNC mode now available - Use REF Sync Mode 1 to 4 with criP greater than 30 deg.

Should be used on all single tooth per firing HALL or OPTICAL sensors (where practical) to give better timing accuracy.

Dual edge mode uses one edge to fire the ignition at cranking (typically 5 to 10 deg) and the other edge to time from when running (typically 60 degrees). This gives better timing accuracy especially for engines with 4 cylinders or less. (Note the minimum number of cylinders for this mode is 2 cyl 4 stroke)

See the E.M.P. help for more detail.
