MMCD logging unit definitions

[90gst_sean]

I've given it a good search and found one good page but it seems to be lacking most the logger abbreviation used in MMCD.

One good page

Does anyone have a list or a link to one?

What abbreviations do you need?

 

[WeaselHack]

Here is what i gathered - this is from MMCd ver 1.8g

Keep in mind that some of the pre-defined sensors in MMCd will show BS or just a static values that mean nothing (IE: fuel pump voltage)...I hope this helps!

Abbreviation, Description, Value
RPM, Engine RMP, RPM Numerical Value
INJD, Injector Duty Cycle, Percentage
KNCK, Engine Knock, Knock Numerical Count
OR-R, O2 Sensor, Voltage
TPS, Throttle Position Sensor, Throttle Position Percentage
MAP, Manifold Absolute Pressure, PSI
TIMA, Timing Advance, Degrees
O2-F, ???,
COOL, Coolant Temperature, F or C (depending on prefs)
AIRT, Air Intake Temperature, F or C (depending on prefs)
BARO, Barometric Pressure, PSI?
INJP, Injector Pulse Width, Time (milliseconds)
BATT, Battery Voltage, Volts
VSPD, ???,
FTRL, Fuel Trim Low,
FTRM, Fuel Trim Mid,
FTRH, Fuel Trim High,
FTO2, ???,
MAFS, MAF Signal / Airflow?, Shown in Hz
ACEL, ???,
FLG0, ???,
FLG2, ???,
OILP, Oil Pressure, PSI
EGT, EGT Temperature, F or C (depending on prefs)
OILT, Oil Temperature, F or C (depending on prefs)
FUEL, Fuel Pressure, PSI
WB02, Wide Band O2,
PLEN, ???,
PUMP, Fuel Pump Voltage,

Yes, that does help; thanks. I figured out you can open a window in MMcd that gives you the all its used deff's.

PLEN: is your intake manifold temp; if I recall.

It's tricky to find, but its in there; udder one in options.

I was wondering about some of the numbers I was logging. Fuel pump volts was one of interest (future rewire) I was taking for granted. The vehicle speed figures are all over the place. Thats obviously not a true reading. Its to bad too; but you can't bi*** about free! Well almost free, anyway.

Thanks for the help in my other thread. I just realizes how close you are to Seattle. You'll should let me in on any big DSM events you partake in. I've yet to find any thing on the side of the state. I'm also looking for an AWD shell or cheapie to swap my moter into. Maybe you've seen one?

NP...Glad I could help!

Seattle is about 230 miles away and I make it out there from time to time but mainly to visit family. I haven't been to too many DSM meets out in your area but I would imagine there are more DSMers in the Seattle area than out here in Eastern WA. You may want to check out posdsm.com - it's a NW DSM site which has frequent meets in your area. Be fore warned though- the members are a bunch of potty mouths and will make you go thru an initiation process but otherwise very knowledgeable and cool in person.

As far as finding a shell, check out seattle.craigslist.org I'm always seeing DSM stuff for sale in their classifieds.

FTO2 = Oxygen sensor fuel trims.
ACEL = Acceleration enrichment.
O2-F = Front oxygen sensor (for 3000GT's maybe?)
VSPD = Vehicle Speed (3KGT's too?)
FLG0 = Flag 0 (not sure what it's for)
FLG2 = Flag 2 (Not sure what it's for)

http://www.hywell.org/plhelp/index.html (Pocketlogger for dummies)

Some of those parameters is stuff that the current MMCD developer, Clint Battersby, has been working on, but everything he's been trying has been for the Stealth/3000GT ECU. If it works with a DSM ecu, great. If it doesn't, then oh well.

 

[90gst_sean]

ya, I had to member-up to get a copy off the 3000 site. It makes sense that'd be what it was developed for.

Any links to palm software more in line with our 1G DSM's thats at comparable price...
ie FREE ?

I'm running MMcdv18g; and thats not a turbo...

Here's the ones that are real on a OBD1 ECU.
The rest in mmcd 1.8g are for when you using the HSLogger custom hardware.

Abbreviation, Description, Value
RPM, Engine RPM, RPM Numerical Value
INJD, Injector Duty Cycle, Percentage
KNCK, Engine Knock, Knock Numerical Count
O2-R, O2 Sensor - Rear Bank V6 (The only O2 on I4), Voltage
TPS, Throttle Position Sensor, Throttle Position Percentage
TIMA, Timing Advance, Degrees
O2-F, O2 Sensor - Front Bank V6, Voltage
COOL, Engine Coolant Temperature, F or C (depending on prefs)
AIRT, Air Intake Temperature, F or C (depending on prefs)
BARO, Barometric Pressure, Bar, InHg (depending on prefs)
INJP, Injector Pulse Width, Time (milliseconds)
BATT, Battery Voltage, Volts
FTRL, Fuel Trim Low,
FTRM, Fuel Trim Mid,
FTRH, Fuel Trim High,
FTO2, Fuel Trim O2,
MAFS, MAF Signal / Airflow, Shown in Hz
ACEL, Acceleration enrichment,
FLG0, Flags 0, TDC PS AC Neutral IPS Switches
FLG2, Flags 2, AC FPS BCS Status
EGT, EGT Temperature, F or C (depending on prefs)
ISC, ISC stepper position

The parameters are described at http://www.vfaq.com/TMO/ or http://www.pocketlogger.com/index.php?pid=params&type=dsm

Ya, I'm having a hard time dialing in my car. I just got it back from some major work. During witch I rebuild the block and decided to used 2G pistons. Granted throwing myself into a one man engine rebuild with get you to sink or swim pretty fast. I still can't wrap my head around all these figures. I knew tunning would become part of the equation sooner or later.

I put together a cable and got my self some free software and started searching, posting, logging, and repeat.

I'm starting to develop a sense of what these number all mean and what to look for. knck, o2-r, tps, tima, injp, and the L M H fuel trims seem to be the most use full of them all. My next step is to look over someone else's logs to get an idea what normal should look like.

At this point I'm not sure if my 2G pistons are messing things up. I'd post a log, but I'm having trouble with that now too. Thats something I can work out later; for now I just need to grasp what normal is a Little more.

I do however have DSMLink installed in a different ECU. Unfortunately, I bought the ECU and sent it to get its "nuts" installed before I ever touched it. Just my luck, it turned out to be a 91+ box; and I drive a 90. I haven't a clue how that one got past me; I thought I looked up the MD#.??? I'm in the process of salving all that; mostly waiting for the ups man to get it all delivered. It may be for the best, though. I'm really starting to dread my FWD; Us two wheelers try not to think about it; but deep down we know we messed up! And with the ECU being a 91+, I'll have a better chance finding an AWD to swap to later.

DSM never should have made turbo FWD's; the only thing there great at are being organ downers for 2G 7 bolter's!!

Well, thanks again for the help guys; its now time to -step away from the computer- before I go blind and my spine falls out. I think I've warn out every seating position know to man and I need to absorb three hours of tuner knowledge before work hits me in four hours like a 2 ton truck.

EDIT: Here are some of the log numbers I managed to pull from the palm. I have a feeling some things not right:
TIMA TPS RPM KNCK O2-R
43 - 99.6 - 3718 - 9 - .64
15 - 99.6 - 3968 - 8 - .87
15 - 99.6 - 4375 - 7 - .87
17 - 99.6 - 4562 - 5 - .85
17 - 99.6 - 4781 - 5 - .85 ..... Do I have to use a power wire with my palm,
15 - 99.6 - 5343 - 18 - .82 ..... I'm only using the three wire home made cable.
11 - 99.6 - 5531 - 24 - .74
15 - 10.1 - 5156 - 0 - .87

NEXT MORNING: For the life of me, I cant get my logs pulled off my palm any more. I've looked through every option of both pc and palm and nothing. I was setting some Velcro up in my car to hold the palm wile I tried to brake some thing doing these WOT pulls, and the battery's fell out.
I loaded 1.8g back on the palm and now I can't pull logs. I'll post some numbers the best I can, but its hard to jot down each fraction of a second moving from second to second with that little plastic stick and a mini screen! My palms not even color.

My car dose not like "full throttle". I get good pull to about 60% peddle, then the rest no change in acceleration really. It almost seems to hurt my poor 17 year old rattle box.

Well I've made some progress on most my latest problems.

- I need a new knock sensor for one. Shortly after these first couple of runs/loggs I got a check engine light code 31 bad knock sensor connection. The sensor has 180,000 miles on it and needs to be changed. I played with it a bit and can now drive with out the check light but will replace it ASAP.
I can feel the timing being pulled seconds before the check light comes on as the ECU reverts to error knock of 9 points. Just goes to show how much a few degrees of timing can affect your performance.

- My PCV valve leaks boost really bad. Its turns out to be the reason I could never do a true boost leak test with out throwing in the towel. I pick up a new Fram valve from Schucks and it leaks more than the year old one I was trying to replace; thats just great!
I decided to cap off the IM nipple and just run the old PCV to my recirculated catch can for the time being. I couldn't bring myself to let it just bleed boost into my crank case like it had been. Fixing this one problem alone has made the most improvement in my cars drivability/performance sense the rebuild.

- Last, my ability to pull logs off my palm mysteriously endding after a day or two of use. This one I'm not 100% sure on but reinstalling MMcd tools solved the problem. I noticed there was an error message about not registering or maybe a registry error. Ether way I'm able to log again and will figure it out later if it happens again.

Thanks for all the help, and until next time; just keep on fixing untill...

 

[WeaselHack]

You are not the only one with PVC woes. I'm going supplement the PVC with a check valve sometime soon: http://all.dejonpowerhouse.com/edit/A-04.htm

Regarding the log file, did you 'toggle' the backup on hot sync checkbox for each of the log file(s) you want to download? Worst case scenario you may want to re-install your palm desktop software or check for the latest version? Good luck!
