I posted this up on the U.D. forums, but I thought it might be worth a shot here too since I'm on HMT most of the time and I know theres a few avid U.D. users here.
I finallt got to test out the new Max233 I bought from Projekteg and all seems to log perfectly fine. RPM is good etc. But, the O2 is not logging correctly. I have selected the appropriate O2 sensor (PLX) and it will throw out a few random numbers, then just hover at 11.8 AFR even when I rev/drive it. My PLX M300 readings are reading correctly, but U.D's are not.It will even fill up the Lambda log with 11.8's, and I know this isn't true.
I've selected different O2's, different COM ports, and Selected different Beaud rates with only the same problem. O2 is not reading. Anyone have any ideas as to what would be causing this? Any help is appreciated. Steve

You are using 38400 baud right?

tranceminister

38400 beuad rate is apparently too slow on my computer. it freezes up and won't log anything. So I've found that running 460800 Works best and does not lock up.

I was told 38400 is the only acceptable rate for Uberdata. I have used higher but the info varies. Remember there is a delay.

tranceminister

Hmmm, not sure. It locks up with 38400. This is with version 1.70 if that matters. I've had to convert a GSR file over to an LS map because of a little bug or something. The LS map throws a solid CEL.

SpankedYA!

Yeah LS map is fucked. There is a beta 1.8 version if you care to try that.

tranceminister

Yep, I just Dl'd it. Looks awesome. They cleaned 1.8 up alot. I'll give it a shot at some point. Maybe tomorrow if it isn't snowing :P

Well guy's I figured out how to get this thing to red the O2. i went over my wideband wiring and discovered I had the narrowband output to the ecu connected and the widebnd output not. So, a quick switch of those wires and it's reading perfectly. It's a slight bit off from what the PLX is reading but it's close enough for me (within a .2 difference). Definately nice to know this things working the way it should. CSaddict I appreciate your help with suggestions etc. Thanks- Steve

Boost n Ls

sounds good steve! good too hear you got that a/f reading correctly. This will definetly help out when you tune.

Glad to hear its working.
