ok, i'm using uberdata 1.7 and LM-1 wb. I am getting the right rpm readings in datalogging, but my a/f is reading 18.63 all the time, no fluxuations at all, it's so hi its off the graph, but if you look in lambda log it just says 18.63 in all the boxes that it went thru rpm wise. I've burned a few chips and I can see changes onmy wb but it's not changing the values in UD.
so far I have tried
-changing my wires on my output signal wire to the d14 pin.
-checked my d14 pin connections and made sure it was D14.
-checked my port settings and changed myadvanced settings to like BMP 38400 and all that crap.
not sure what else to check.

Use a volt meter to ensure your getting the proper voltage range from your wideband.

You need to calibrate uberdata for your LM-1. Did you choose Innovate from the drop down menu?

"Use a volt meter to ensure your getting the proper voltage range from your wideband"
where do I check the voltage from? And why would I get correct rpm readings but not a/f?

"You need to calibrate uberdata for your LM-1"

How do you do that? I have checked the tab in uberdata for my Innovative wb, is there anything else to do?

you should get a voltmeter and check the readings at the output of the wideband.....it should be around 1-3 volts and if you drive it or give it some gas, it should change. If this yields nothing, something is wrong with your wideband. If you get good values, then quadruple check you put it on d14 and correctly grounded the wideband to the same ground as the ECU (closer reading because of less variance) and install a capcitor in parallel (less noise). Are the other inputs working like RPM and TPS and all that stuff. If not then you have a datalogging problem. Report back with results of your voltmeter test

yes, I checked my d14 pin, FOR sure it's correct and a good connection. My ground is good because it's the same ground that I used to power my WB and it's working correctly. My RPM #'s are dead on, but just my a/f is off, it's not only off, it's not even changing, it just reads 18.63 all the time, no matter what the wb says. I'm on vacation until sunday so I can't check my voltage, but i will when I get home, any other ideas anyone?? it would be helpful

You have D14 hooked up to the LM1 controller using the audio cable correct? did you set up the analog outputs for the LM1 correctly with the LM1 config software?

EDIT: you should have 3 wires coming from your LM1 analog audio cable. A red wire, white wire and a braided copper wire. I think the red wire is analog 1 and white is analog 2, and the braided wire is ground. D14 should be hooked up to one of your analog outputs and A26, the ECU ground, should be hooked up to the braided copper wire.

no I didn't do this step, ill do it next, thanks

BlueShadow

Yah you wanna look at page 11-15 of the LM1 manual (not the quick start quide).

You might wanna check and see what numbers people are using for Uberdata though. For Crome I use 0.5 Volts = 1.36 Lambda and 3.8 Volts = 0.68 Lambda. You'll know you have the corret numbers when your LM1 controller matches what Uberdata is reading.

i programed the analog outputs to
0v 7.39 AFR
5v 22.09 AFR
and it didnt do anything, any more ideas??
Is there someway I can change some settings in UD to match the volt to a/f??

adseguy

Yep. It's under "void timer250()" in the datalogging.als.txt. Add your own custom one or change another one. you'll have to fiddle around to get the right numbers to come out, but it's not that hard.

pa2play

so should it look exactly like this when I'm done?
// Innovative
if(x == 2)
{
af = (sreply * 2.95) + 7.39;
}

adseguy

It may or may not be close. Like I said, fiddle around with the numbers until they correspond correctly.

I checked the voltage from analog wire from wb and it read 2.52 and would fluxuate alitle if I hit the gas. I also checked the connection to d14, it's great, I sodered it and the voltage reads the same there. The Stock o2 wire is cut in 1/2, with red analog wire hooked up to the wire that comes off the ecu, d14 (red with white line), checked it lke 6 times according to this http://www.plxdevices.com/ECUD...5.pdf
then I grounded it out about 1 inch from ecu on A24 (black wire) then pluged the the analog wire into analog spot on WB. In UD I picked the innovative wb and com 3 and my rpms are datalogging fine again, but a/f isn't. O I also programed the analog outputs on the WB both to the same 0v 7.39 AFR
5v 22.09 AFR
so it didn't matter which one I used.
I messed around the the numbers in the datalogging.txt but it did nothing. It would just set the umbers higher or lower, but not change the fact that it isn't working. Is there anything else I can check or change?

adseguy

well if you are getting 2.52 volts and it changes off the wire and you are able to datalog the problem now lies between that wire and the datalogging cable. This is a tough one indeed. Try using ECUcontrol to see if it can see it. Try burning a fresh stock bin (only adjusted for injectors and disable 02). After that I really don't know what to tell you but to read up on Uberdata forums or keep adjusting the values in the datalogging text. GL....seems like this sucks

bump anyone else, still havn't gotten it to work yet
