Datalogger MMCD, Wideband input??

titogs95 · 01-13-2006, 05:48 PM

I am using MMCD Version 1.8G...
In one of the sensor reading I have options like WB02, EGT, MAP, OIL T, FUEL......
So what I am wondering is if I get a Wideband like PLX. And I am wondering if I can input the reading of the Wideband into my logger. Either using the EGR T input or something else. What other input sensors can I use? Where do I plug it?

Here is a related link but didn't answer my question.

Thanks in advance,
Tito

These guys can help you out: http://autos.groups.yahoo.com/group/dsm-ecu/

Thanks, It gave me the Idea of Burn a function in the CHIP wich remplace my Narroband for a Wideband instead..... It can be done (the guy who burn the chip told me) but Now I have to figure out the wiring...

For future reference:
If you are using MMCD 1.8G, You need to go to: Options> Preference>
Once you are in preference, You will see a the word EGRT next to it you can choose what value you are going to input. values like: 3.0 Bar, 2.5Bar, 2.0Bar, WBO2, EGRT & 0-5V.
Then all you need to do is Hook up the wire into the EGRT place. (I Think this is for Federal cars only, because CAlifornia cars may fail Emission :blahblah: )

NEW Problem...
I Finally got a WIDEBAND from PLX.....
I am using MMCD tool to download the logging. But, My problem is that it keep showing up as a EGR-TEMPERATURE instead of 0-5V from the wideband, Does any body has a Formula to convert it back to 0-5V or to AFR?
In my datalogger is in AFR or 0-5V, it is the mmcd Tool that keep converting it back to EGRT

TIA

Nobody knows? Wiseman?
Anyway, does anybody know to whom I can email for Info? (whoever created this)
I tried to email to spoulson2@users.sourceforge.net (in is in the web site above). But the email is no longer working...
All I am wondering is at what Voltage certain Temperature has to be so I can come up with a formula. What is the heat range of the EGRT.....
Please Help me...

Where do you get version 1.8g?

Just follow the same steps that I did when I hooked up a MAP sensor to let MMCD log boost. As long as your wideband has a 0-5 volt output, my writeup should work.

Anyone using there MMCD to log their wideband and how do you like it? Since I already have a palm seems alot cheaper to log with it on there

titogs95 · 02-07-2006, 11:07 PM

Well I can log it and I like it so far. My only issue is that I can't transfer my A/F datat to my PC because it keep reading it as a EGR temperature. Other than that, It is great.

Soon, I will find a way to convert the data back to Voltage. As soon as I find out how much "x" temperature is in Voltage.

Hell yeah it is a cheap way....

93jdmlaser · 02-07-2006, 11:15 PM

so it converts the 0-5v signal from the wideband to afr on the logger you just cant read that on the pc? Aslong as it converts it on the logger I should be ok with that for now. Thanks

Yeah for Now I can read it (it is not that hard to read) on the Logger as a A/F ratio or 0-5V.
But when I transfer the log to Excel. It convert the data automatically to Temperature. When I find a way to fix it. I will post it.

1SloColt · 02-08-2006, 08:51 AM

Does the MMcD already have the built in scale to show the AFR from say 10:1 - 18:1? Or is it just showing the voltage output?

Yes. Boths!

0-5V = 8.0 - 22.0 AFR

Finally, I got around doing a little table converting the numbers (EGR-T) to A/F ratio. I got it by reading it directly from my PDA. I kept changing between A/f ratio to EGR-T (Numeral) (It is an option in the MMCD software).

This is what I came up with. I hope it help for the future....

It is not perfect but it should do the Job.
LINK deleted. It won't Work.

Since the mmcdTools is open source, I am in the process of changing some of those things so they show correctly in excel when it is converted.

I cant remember any of my programming stuff, so I have to have my roommate fix some of the programming errors in the posted src code.

Cool. That is a better solution for the problem.

Keep me updated.

dnhieu · 10-18-2006, 02:53 PM

So it reads a perfect afr on your logger then right? also do i just follow his dsmtalk write up to the dot but hook up a wide band instead of a pressure sensor? also what about the LM-1? does it have inputs to plug into my ecu so my palm can read it? is this evne how i do it?

thanks

Sorry to bring this thread up from the grave but is there a way to change the scale for the wideband on MMCD. My problem is that my LC-1 is alittle off from the MMCD scale. The AFR is not converted quite right. I could change the output of the wideband but I dont have a laptop right now. I would much rather change the MMCD scale. Any help would rock.

yeah. I wish there is an easy way through MMCD.

Something you can do is measure it by the 0-5 Volts. then calculate the A/R from Lc-1 website (2 page)

Quote:

The default analog outputs are as follows: Analog output one (yellow) is 1.1V = 14 AFR and .1V = 15 AFR. This is a simulated narrowband signal. Analog output two (brown) is setup as 0V = 7.35 AFR and 5V = 22.39 AFR.

Per example=
2.5V should be 14.87

BRAINSTORM:
Something I saw in the Chilton book, is that EGR Temperature (In california's car) input is a variable resistance.
I wish I know what are the range values of the sensor.
According to MMCD is this -2.7x + 597.7 in F

As I said early in the thread: what volts are equal to what Temperature or raw data, to do an easy conversion formula.

BTW the part number is MD131905
