MMCd New Features

[cbatters]

16-4-05 Posted V1.8g (see below)

Starting this thread to review MMCd bugs and discuss possible new features. I would also like to see if there are other 3SI members interested in doing SW development. (Dev environment is free and takes less than an hour to set up.)

My goal is to periodically summarize feedback / posts on this page.

NEW SOFTWARE FEATURES
1. Auto Logging on Event (cbatters - done)
2. Peak - Hold (cbatters - done)
3. Upload / Convert to CSV (Shawn ????)
4. Address data scaling issues in log files
5. Big Number Mode (TurboBob?)
6. Graphical Gages
7. User Scaling/Config for Custom Inputs
8. User configuration for graph scaling (colors/scaling/offset)
9. User config for all sensors (colors/scaling)
10. User defined log rates / prelog / postlog
11. User defined graphical display time resolution
12. User defined alarm tones
13. Graphical alarm alert

Other suggestions...

HSLogger Project
Interface for adding additional inputs to the MMCd logger. New inputs include:

o Boost (x1) (Using either 2.5 or 3.0 MAP sensor)
o Wideband O2 (x1)
o Oil Pressure (x1)
o Fuel Pressure (x1)
o Intake Manifold Air Temp (x1)
o 0-15V input (x1) (Fuel pump voltage)

o EGT (x1)

o Other
o Vehicle speed (1) and derived calculations
- MPG
- 0-60 timing
- AWD HP

Models / Pricing
Planning to offer three different models of the HSLogger.

HSLogger Base - Fixes baud rate / RS232 level issues to allow compatibility with ALL Palm devices and includes Speed/Odometer input for performance / MPG calculations. You can also log boost with the unused EGRT input. (~$100)

HSLogger Exp - All of the Base unit features plus six 0-5V inputs (Pressure/Boost/Wideband O2 etc from existing sensors/gages - any 0-5V signal) (~$175)

HSLogger Deluxe - All of the Exp unit features plus higher resolution for low level inputs with signal conditioning for direct connection to sensors. Deluxe version has an "analog front end" that provides amplification, filtering, sensor excitation for direct connection to EGT Thermocouples, oil/fuel pressure senders, etc. (~$250)

I believe the Base unit is is competitively priced based on quality passive cables for $75 from Mirage or $150 for PocketLogger SW + Cable. (In my not so humble opinion, MMCd now runs circles around the PocketLogger SW.)

Q1 - What do the letters mean in FLAG0 and FLAG2

Flag 02 status bits
A - Air conditioning relay
F - Fuel pump relay
B - Boost related ???

Flag 00 status bits
T - TDC sensor
S - Power Steering Pressure SW
A - AC switch
N - Neutral
I - Idle switch

Q2 - How do I view MMCd logs on a PC?

MMCd has built in support to upload logs using the Palms archive file capability by simply flagging the log files in MMCd. Files will automatically get uploaded to Palm User - Archive directory on the PC the next time you hotsync.

Simple solution for reviewing logs is to download the PalmSimulator which allows you to run MMCd on the PC. (Just drag MMCd program and log files to the simulator window.)

The other choice is to download MMCdTools which provides a conduit for xfer of logs files as well as conversion of MMCd log format to CSV.

SUMMARY OF CHANGES

KNOWN ISSUES:
Buttons/checkbox controls cause delays in log sampling rate

INVESTIGATION:
Min/Max button
User defined prelog / postlog times
Consider adding default Autolog triggers
Correct slug for EGRT WBO2 inputs - currently hard coded as MAP
Need to confirm Boost solenoid status display
Need to define/implement new log format (mS resolution / Integer / Long / Char )
Scaling for AFR input - Changed in 1.6N
Old 0-5V = 10.0 - 20.0 AFR
New 0-5V = 8.0 - 22.0 AFR
Configurable option for 3S versus DSM mode
- Timing
- Other differences?

What are you using as a development environment? I've been building it under Unix.

Windows using PRC/CYGWIN setup. Adding dev links to the original post.

I'd like to contribute. I'll start setting up.

I'll work on "big number mode"

Divide / conquer -

I'll send you an email with the right SDKs and a few notes on setting up the environment. (too big to post here)

I'll also put your initials next to Big Numbers Mode!

Hooray for big numbers!

Stupid question follows ....
How hard would it be to convert
MMCD for use on a laptop?
I've used it in a Palm emulator,
but the sample rate goes way down ..

Not a stupoid question...

Pretty much a rewrite to get this to run natively under Windows. I had toyed with porting it to PocketPC/CE but came to the conclusion that it was not worth the effort given the low cost / availability of cheap Palm devices that are well suited to automotive logging.

Best Wiondows based 1G logger is still probably TMO but it suffers from only a single O2 sensor.

RE: Simulation.
Advise what type of notebook (speed/memory/OS) you were using. I have not run MMCd live using the serial port but I run the simulation for testing and the MMCd UI was much faster on a P3-500 than it was on my Palm V.

NEW AUTO-LOG MODEL
Just tossing out a few ideas for auto-logging mode. My goal is to make it possible to leave auto-logging enabled to catch any events while getting rid of boring "cruising" logs. (Consider a log that only included information when TPS>50% or RPM > 3500)

1. Add auto-log option to alarm UI configuration

2. Add option of silent alarms

3. Any alarm can trigger auto data logging

4. Add user configurable auto-log timer (continue logging for xxx seconds after trigger)

5. Auto-logging on / off control under preferences

6. Manual logging will override and temporarily disable auto-logging
