The rate at which data can be acquired is limited by the communication speed - 8192 baud in this case. Each mode 1 request is 4 bytes long, the mode 1 reply is 63 bytes of data and 4 framing bytes, each byte is sent using ten bits (1 start,8 data,1 stop) so that's 8192/710=11.5Hz (87ms period). ElanScan can manage 100ms no problem (and maybe a ms or three fewer).
I'll stick in the usual disclaimer here. I make no guarantees to the utility or reliability of the software. If you use it you use you use it at your own risk.
If you have a version already installed delete the 'M100 ALDL protocol.ini' file from the windows folder. This allows a new, updated, parameter description file to be created. The new version might choke if you don't (and it won't show the up-to-date parameter list)...
Here is the download:
ElanScan (0.9.9.61)
Version 0.9.9.61 Modified comm routines to be tolerant of time gaps in data stream. Reduces communication errors significantly in some cases.
Version 0.9.9.58 Fixed bug with graph print (pretty fundamental error in the graph draw routine as it turned out), added default type to PROM dump dialog, re-built to include enhancemen]ts in the COMMS code I made for something else (i.e. it probably won't work any more :) ).
Version 0.9.9.54 Remembers your COMM port, serial port set up more elegantly (but you won't notice any difference as a user), corrected MAP calculations (thanks to Gary Harris), added DRP - distributor reference pulse - (again thanks to Gary) - not sure about this one I can't see why it doesn't scale linearly with RPM - & it works in Windows 95.
Version 0.9.9.46 Error codes complete (guesses), injector duty cycle added, wastegate duty cycle calc corrected
Version 0.9.9.45 Changed live display methods - hopefully addressing problems reported
Version 0.9.8.41 Fixed a couple of bugs (around starting and stopping talking/logging). Added optional gauges (manifold pressure & RPM) for use during tuning. Enable in Setup and they'll appear when 'Start talking' or 'Start logging' is pressed.
Version 0.9.8.37 Improved memory management, added more calculated parameters (acceleration,power,gear - they are pretty approximate but seem to be about right), graphing of individual bits now allowed, more stuff I can't remember right now. Its still changing rapidly, treat as an alpha version (keep the old version handy!)
Version 0.6.6.30 Parameters updated (changed my mind on quite a few), graphing bug fixed.
Version 0.6.5.29 Tree view replaced table (breaks out bits), resizeable control dialog, comments edit, status bars (x,y coordinates, instructions), WOT cable support....
Version 0.5.4.27 Sets RTS and DTR high
Version 0.5.4.26 Fixed another file loading bug & added function key control of buttons.
Version 0.5.3.23 Now the distance calculation works again...
Version 0.5.3.22 Oops - logging was broken in 21.... Fixed now (I hope)
Version 0.5.3.21 Fixed a file loading bug, added a calculated distance parameter.
Version 0.5.3.17 Added comparison feature. Improved(?) interface, updated parameter table (many parameters are speculative, be critical)
Version 0.2.2.8: Added data browsing and cursor feature, updated parameter table.
Version 0.1.1.6: Added APM support (laptop doesn't standby/suspend, unless battery power is critical, when logging), fixed various bugs, gave up on real time graphing (too time consuming)
I've added a zip of a required dll (thanks Rob) put it in the windows system folder (c:\windows\system or equivalent)
qtintf.zip - I'm not sure if this is still required, I've run the program ok on a PC without it.
If you use Windows 95 and can't see the graphics on the buttons get the latest version of Comctl32.dll.
and here are some log files I've taken:
