New Software In the new year, we had a software update roll-out that caused some issue with a select few OFT’s where they would no longer read/write the ECU, or interact with OpenFlash Manager to upload/download ROM files and Datalogs. 1010 N Batavia St STE J Orange, CA 92867, USA; Terms of Service Privacy Policy © copyright 2021.

BMWFlash is absolutely free for personal use! If you use this commercially please donate. We offer absolutely no warranty, as this is freeware.

BMWFlash allows you to read out an MSS52, MSS54, or MSS54HP DME completely. You can also just read out the data area to save for editing and reflash your changes back. These features are free for development purposes, as the DIY community has taken a keen interest in the MSS54 platform.
http://www.m3forum.net/m3forum/showthread.php?t=423771

It will not reflash the entire DME contents, only the data area. The checksum is automatically corrected on MSS52, MSS54, and MSS54HP before a flash occurs.

EcuFlash is a general-purpose ECU reflashing and editing tool that supports an ever-growing list of vehicles. EcuFlash uses the OpenPort vehicle interface to reflash vehicles via the OBDII port. EcuFlash also allows you to edit ECU data (known as 'maps' or 'tables') in a human-readable format using a XML-based definition system to translate the data. With properly setup definitions, the ROM from any vehicle can be edited. Future plans for EcuFlash include logging support / overlay, and live tuning.

EcuFlash version 1.38 for Mac OSX is provided for legacy OpenPort 1.3 cable support only. There is currently no EcuFlash support for the OpenPort 2.0 pending necessary OSX driver development. Alternately, EcuFlash 1.44 will work by running parallels on OSX.

Changes:

-- bug fixes --

• CAN: only send additional flow control frames if ISO15765_BS is not 0
• CAN: complete missing implementation of ISO15765_BS and ISO15765_BS_TX which are needed to limit the number of continuing CAN messages sent between waiting for additional flow control (FC) messages from the other party.
• CAN: return CAN_29BIT_ID flag on appropriate read results (was being masked by accident)

J2534 DLL

--- features ---

• Contains newest firmware for OP2 (see below for details)
• Add J2534 extension to support variable number of stop bits in serial communications
• DLL is now signed and has correct version info
• Added ability to add phase offset to periodic messages to control the relative timing of multiple periodic messages

• Up NUM_PT_CHANNELS to 9 to support innovate

Driver

--- features ---

• Driver synchronizes OP2 to system clock to allow log files to have correct time / date if OP2 remains plugged into the car
• IMPORTANT - the OP2 now uses a custom driver I wrote for better speed and stability than the Microsoft usbser.sys driver. This allows for reduced latency and a cleaner installation as well. *** This means that initially you must do a full EcuFlash and J2534 / driver install so that all of these components will work together. OLDER ECUFLASH AND OP20PT32.DLL VERSIONS WILL NOT WORK WITH THE DRIVER. **

--- bug fixes ---

• Use exclusive file access to prevent multiple connections to the driver
• Add USB data disposal when no file is opened

Firmware

-- new features --

• Add logging support for Zeitronix ZT2/ZT3 devices (see samples)
• Add support for clock synchornization with dirver in order to have accurate file time / date
• Add support for 32bit ints with no scaling to avoid loss in precision in that case (before, everything was promoted to a float32). This feature only happens if there is no scaling done to the value
• Add finer granularity to 'friendly' logging intervals
• Add ability to tweak OBD CAN and MRMACAN logging timing using calcsampinterval and calcconstantdelay parameters
• Add support for mode $01,$22, and $23 OBD CAN logging
• Add support for logging from AEM UEGO and any other devices which output ASCII streams of data (see logging examples)
• Add J2534 extension to support variable number of stop bits in serial communications
• Add support for LM-1, in both headerless and V2 header configurations (see logging examples)
• Add support for logging signed parameters using issignedint=1
• Add support for 50kbps CAN
• Up to 60 parameters allowed
• Completely changed innovate MTS bus logging to support multiple LC-1 and other MTS devices (see subaru k-line adc lc1.txt sample for details)
• Support for more flexible lower speed/priority parameter sampling through the use of a new additional parameter feature called sampgroup.

sampgroups are numbered 1 through 15, the number simply being a label. All parameters in the same sampgroup will share a single timeslot. The OP2 will determine how many of each sampgroup there are, build a cycle of that size, and phase each of them properly. This allows you to have different groups of low speed parameters, running at different speeds, each optimally using the sample cycle. (see subaru k-line adc lc1.txt sample for details)
priority = 2 is still allowed, but all it does is assigned the parameter to sampgroup = 1

• SD card uses DMA for greater speed in all cases
• SD card multiblock read / write to increase speed when connected to USB (800kB/s read / 500kB/s write is typical)
• Filesystem operations queued to a separate thread to allow seamless logging regardless of SD card latency
• Multibyte parameter (up to 32-bit) mitsubishi support
• Support for zeroing sample count each time a new file is started using zerosamplecount = 1
• Support for zeroing time count each time a new file is started using zerotimecount = 1
• Time count starts on nice intervals
• Time only shows to the millisecond
• Increased range and fine-granulatrity of possible logging intervals
• Improved details in logcfg.out dumps
• Support for filling in missing samples if ECU misses a response or two using fillmissingsamples = 1
• Support for new file cuttting action 'newfile' which starts a new file if your conditions are met (see subaru k-line adc lc1.txt sample for details)
• Improved timing estimates for most logging protocols
• Up to 4 logging channels allowed (e.g. ssmcan, lc-1, adc, & calculated data)
• Support for fast RAM parameters on Subaru CAN vehicles (assuming ROM patch has been made). just use the known RAM parameter ID (0xFFxxxx) and the OP2 will do the rest. reading of multibyte RAM parameters is sped up by the ROM patch which allow reading up to 4 bytes with a specially encoded 3-byte parameter request. due to current Subaru output buffer limitations, only 80 bytes can be returned in a single request, so only 20 4-byte params can be read at a time. i will make some changes to the OP2 firmware in the future to issue multiple requests to overcome this 80-byte of data limit.
• New 'previous value' parameter added to RPN expressions (e.g. '#RPM' instead of 'RPM'). this is useful in creating trigger conditions that are sensitive to the direction of change in a value. for example, if you wanted to capture each dyno pull from 2000rpm to 7000rpm to a separate file, you could set the following conditions:

conditionrpn = #RPM,2000,<,RPM,2000,>=,&&
action = start
conditionrpn = #RPM,7000,<,RPM,7000,>=,&&
action = stop

• Writing of logcfg.out has been speed up 100x or more - there is little need to use the debug=noout option anymore
• Added some more finely spaced 'friendly' logging intervals
• Time now starts at 1/1/2009 each time the OP2 boots to give more reasonable looking file times
• Green status light now blinks during 5 baud inits (e.g. MUTII)
• Parameters and triggers now use RPN based scalings so that you can do arbitrary equations or evaluations. i will add an infix (algebraic/parenthetical) to RPN parser later for those who are confused by RPN...
• Calculated / derived parameters are now supported - you can now make new parameters based on equations of other parameters
• MUTII logging is now much more robust - it will re-initialize if there is a break in communications
• CAN (SSM/MRMACAN) logging is more robust - it will retry if there is a break in communications
• SSM K-line logging is more robust - it will retry if there is a break in communications (it used to be this way before, but I had broke it with the priority logging)
• Added the ability to set voltages or ground pins - this is handy for MUTII users who need to ground pin 1
• Added isvisible option to parameters so that you can use them for triggering or calculations, but not write them to the log file
• isfloat=1 parameters automatically default to databits=32 now

-- logging bug fixes --

• Fix bug causing Innovate MTS to log at 9600 baud
• Fix offset error in Mode $22 OBD logging
• Fix bug writing more than 512 bytes at a time to file queue
• Increase size of parameter header line buffer to accommodate long parameter names
• Fix error in && and || tokens
• Increase speed of SSM K-line comms
• Fix occasional failed transition to logging after USB disconnect
• Fix overly-rapid mitsubishi communication attempts if ECU not responding
• Collecting lc-1 data does not cause additional steps in the sample countfix bug where logging could sometimes start immediately after a firmware reflash without they normal delay to check for USB
• Fix bug where long SSM responses were not correctly parsed
• Fix bug where 32 bit data fields (such as floats) were not masked correctly
• Increased mrmacan logging interval estimates to avoid sampling overruns* logging mode now starts if the OP2 is already plugged into OBD and you remove the USB connection - this means you don't have to unplug the OP2 from OBD at all between logging / reading logs / tuning / flashing / etc.
• Databits values over 31 could be truncated
• Sample time is now in units of seconds
• Sample number now should increment by 1 per log cycle for mitsubishis
• Fix innovate baud rate bug
