Datalogging With Uberdata
 

Soldered up the USB, got the drivers, but can't seem to get datalogging to work . . . . what could be the problem? I tried different ports, and it still doesn't seem to wana work.

HELP so I can tune.

Re: Datalogging With Uberdata
 

do you have a bin open?
did you select the com port in uberdata under the datalogging tab
did you select the sensors you want to moniter

Re: Datalogging With Uberdata
 

Ditto. Those are the 3 essential things you have to do at the very least to get datalogging to start.

Re: Datalogging With Uberdata
 

thanks guys but I did indeed do the 3 things mentioned above, and still nothing.

I opened the bin I currently am running in the car, and I checked all the items or parameters that I wanted and still nothing. Could it be anything else?

Re: Datalogging With Uberdata
 

did you try all the com port options
is the led on your ecu on

Re: Datalogging With Uberdata
 

yeah I tried them all . . . most said error, only COM Port 1 worked as far as no error, but it still didn't read. As far as the led, what led would that be?

Re: Datalogging With Uberdata
 

Plug in the USB cable and go to device manager. See which COM port its really on. If all are taken that Uberdata can use, force one from its position and force that one into it. Some of the widebands need that trick.

Re: Datalogging With Uberdata
 

i'll give that a try. Now what about the solid CEL when dissabling the o2 sensor, and dissabling closed loop? The car runs great like that, just need to fine tune the boost portion, but i'll be testing out the ecu, and usb stuff today and report back.

Thanks

Re: Datalogging With Uberdata
 

What kind of wideband are you using? :-X

Re: Datalogging With Uberdata
 

PLX 300

Re: Datalogging With Uberdata
 

You sure it's a solid CEL when you disable the O2? That doesn't sound right. You need to jump the service connector with a paper clip to get the CEL to actually flash the code.

Re: Datalogging With Uberdata
 

You may want to check your soldering... :P

Also, make sure you CUT D14 and run your wideband wire to the harness/plug. You don't want a narrow signal from the stock O2 or the O2 output from the PLX unit. I would add the capacitor as well.

You should also be checking the O2 heater & Closed Loop boxes in your bin, saving and then burning that to a chip. Put chip in car, start & hook up datalog cable. From there, open up Uber and go to the datalog tab and select a COM port, your wideband (PLX) & check the O2 box. You should see something happen on the datalog page.

I have the same wideband by the way. Works great. :y

Re: Datalogging With Uberdata
 

so what compacitor are you talking about? I do check o2 heater, and the closed loop box when burning the chips =) So I gota cut D14 or splice into it? Got a diagram of that I can check out?

Re: Datalogging With Uberdata
 

Your PLX unit should have come with a small capacitor. Check their website for a diagram & specs. I think it's -.1unF or something. I bought a whole bag of them at Radio Shack for a few bucks.

As far as your wideband hookup... You need to cut D14 at the ECU. Cap the loose wire from your O2 sensor & run the wideband signal from your wideband unit to the D14 plug/harness. Now your ecu is seeing a wideband signal and NOT a narrow signal.
