Which wideband?

[tstkl]

the egr-t wire. its not there on vfaq, so I dunno which pin it is, but if you really wanted to, follow the pin from the relay that is attached to the ecu i guess. that would be too hard though in my opinion. wait til some 2g guy comes with a solution, or look on those dsm manual on cd disks, they should have "everything"

 

[tstkl]

so I bought a digital volt meter, and Im looking for a good way to source a full time power supply for the backlight. does it need a 12 volt supply or a 5 volt supply? what source did you use? I think Ill just tap into my wideband's 12 volt source, but I dunno. I know at least 9 volts will do, I don't want this thing to burn out super fast. I tried a 9v battery, thats how I know.

So can would I be able to use the AEM UEGO gauge type wideband with the pocketlogger? Or would this be a futile pursuit? I almost purchased this guage type wideband and I won't be using a laptop so is the pocketlogger enough?

Yes the AEM UEGO has a 0-5V analog output, after you splice that to your egrt connector it can be read with capable pocketlogger software. MMCD version 1.8 lets you read all sorts of inputs in the egrt including AFR. You can log it with RPM and there is a complete tuning solution. Hope that answers your question. I honestly wouldn't bother with a guage type AFR display, why be distracted by yet ANOTHER disply to read when you are WOT?? Just read it later in your log and concentrate on knock and not overevving your motor. Just my opinion mind you , YMMV.

Exactly what was needed. Thanks!

My volt-meter backlight works on 5V draw. You can use pin 23 on the ECU for a 5V source.

wish I knew this 20 minutes ago, guess what I just burnt out...

If you set the innovate set to display 1.00V @10.0:1 AFR, and 2.00V @20.0:1 AFR, you just have to move the decimal one place for AFR.... 1.47V= 14.7:1AFR, 1.11V= 11.1:1 AFR, etc. See what I mean?

I just got my LC-1 the other day and installed this morning. Great piece BTW

I used your calibration above on one of the analog outputs to my S-AFC via the "Blue Wire Mod". Unfortunately the S-AFC read ~.09V (1.18V vs 12.5:1 AFR) lower than what Log Works read on my laptop . Have you directly compared your eBay display to Log Works yourself to ensure both read the same?

You will probably need to do a little calibration for differences in ground. Program the LC-1 to display 1.50V @ 9.0:1 AFR and 1.5-0V @ 20.0:1 AFR. This will make it output a constant voltage. Then check your S-AFC reading and see what it says. If it is reading 1.55V, for example, you would want to scale both your calibration inputs by .05V.

I have checked my display against logworks - and with a little calibration it was exact.

Rain finally stopped and was able to give it a better test. The S-AFC "Blue Wire" input is definitely the problem not the calibration. Testing the same LC-1 analog output w/ same calibration with my Multimeter I was spot-on what the Log Works display showed.

I've since calibrated Analog2 for use with my TMO Datalogger via the EGR-T Input and again, spot-on to what Log Works displayed

A great tool and a very good bargain at $199

My only computer is my desktop, so does anyone mind telling me the two points used for the "factory settings" or the two points your using for your output to the egr-t port, if your using mmcd version 1.8g. basically if anyone could tell me the factory settings, or two points they used for mmcd version 1.8g via the egr-t port, that would be great. I have it on factory settings and it seems right, kinda, but the thread on 3si.org says that the wideband input for the egr-t is 0v=8, 5v=22. Im pretty sure thats wrong.

If you've set the LC-1's analog out calibration to 0v = 8:1 and 5v = 22:1, then it should work with those settings.

BTW, where did you get MMCD v1.8? I thought I had the most recent "Beta" which is 1.71

pm me if you want it and are too lazy to register yourself

btw, with the engine off and the key out, my palm reads an afr of 20.5, shouldn't it read 0 volts or 8 afr. Thats why I think that scale is wrong. Also, there are two wideband spots on mmcd version 1.8g, so I think thats for the other one. Im not getting any answers from 3si though.

With the engine off and key out the MMCD will receive no signal from the ECU nor will the LC-1 be powered. It may be just that the MMCD software is registering the max value as a default? You did hit the "program" button on the Log Works Programmer to update the LC-1 with the new calibrations right and are using the correct analog out?

If you look at the release notes .txt file for v1.8g

15-07-04: v1.6o
- Changed AFR scaling to 8.00 -> 22.0 (limited testing)

So for this I assume setting the LC-1/LM-1 to output 8AFR = 0V and 22AFR = 5V the MMCD will correctly display AFR within that range. I'll try it out tonight to see if it works

what Im saying is that I think thats for the wideband 02 input on page 4, while Im talking about the egr-t import scaled for a wideband o2 sensor. There are two different wideband o2 spots on 1.8g

The EGR-T input that is selectable under preferences will show MAP, WBO2, EGRT..etc on Page 1 of the MMCD Display. That is the one that you need to use.

Testing the calibration 0V=8:1 and 5V=22:1 I tied out exactly to my Analog Output2 which was connected to my Volt Meter with the 1V=10:1 / 2V=20:1 which ties out exactly to Log Works.

So either you've hooked it up incorrectly (bad ground) or did not load the calibrations correctly from LM Programmer.

thanks

btw, do you like 1.8g?

 

[DSM90AWD]

btw, do you like 1.8g?

I had 1.71 previously which is cool as it was a bit less "busy" and had Lb/Min calcualtions (well until you hit 38 and then it bombs out ), but was not 100% compatible with the Palm Tool exporter w.r.t. the new parameters added.

1.8g seems ok sofar ( I downloaded it a few days ago in response to your query ). Still on the learing curve to see what all it can do and figure out how to do it.

Would be nice if a manual existed, then again this is freeware.

Back on topic, I've gotten the LC-1 to work flawlessly on MMCD v1.8g, TMO 1.16.03, Volt Meter and of course the included Log Works Datalogging software

For the archives...
To use TMO Datalogger v1.16.03, I set the LC-1 to 0V = 8:1 / 5V = 22:1 (same as the MMCD v1.8g calibration so could use both and not have to change it) and set the TMO Settings to :

Name = AFR
Offset = 8 (what 0V corresponds to)
Slope = 2.8 (22 - 8 / 5V)
Units = AFR
Precision = 1
Minimum = 9 (minimum for the display, will still datalog from 8:1)
Maximum = 16 (maximum for the display, will still datalog to 22:1)

 

[tstkl]

Im pretty sure that the lbs/min on version 1.71 along with a lot of other things were just flat out wrong. When I had it I saw 30 something lbs/min just about every day when driving around town. The maf would read like 1300 hz or less and I would be seeing numbers that shouldn't be possible on a 14b with no mods (at the time) I stopped using it because that and the injector duty cycle along with a lot of other things just seemed wrong. I like 1.8g a lot better.

So I finally am ready to install the lc-1 but trying to figure out if anyone else has installed it ,if they can tell me how they wired it.I'm trying to hook it up with my dsmlink so if anyone has this already setup, please let me know.I want to get this on as soon as possible.Thanks.

 

[tstkl]

follow the instructions and wire output 1 into the correct pin on your ecu. most people use the egr-t sensor input.

 

[dnhieu]

so you wire output 1 into pin number 23 on a 1st gens ecu? do you just t-tap it?

 

[rated x]

I have a 2g,so how would I do that?
