When i try connect my WB to laptop (thru USB adapter cable) i open megatune and get this error:

log file: http://www.hot.ee/ranz/audit.log
And the gauge makes somekind of buzzi nois and it's wery disturbing and loud.
I think you're using the wrong MegaTune use this one:

That noise is not unusual, there's work underway for a new version of the Gauge's software that will kill the noise.

No, thats the same version what i am using, downloaded from the other topic where was somkinde of connection problem but mine seems to be something else >:(
If you say no to Terminate MegaTune what happens?
You may find that you have to change the comm port in the MegaTune setup
Rob
When i push no, megatune starts but does not connect. My USB to com port adapter is configured to com port 2, when i change megatune to same port and push test, it says no connection.
USB adaptors are the biggest source of communication problems that we have.
Thats what i thought. I'll try to connet it directly to my desktop computers com port.
Problem stays. I found laptop with COM port and when i connect it directly there i get same error :( no connection of anykinde...
EDIT: The error linked in first post appears only first time when i start megatune [I downloaded it again and tryed, there it was, in second start was not). Then it's on COM port 3, I change it to COM1 and when I close and open megatune I get this error:
(http://www.hot.ee/ranz/com.jpg)
But it is on COM1 and still no connection. I tried to change computer settings and ports... nothing :( test button says no responce!
I get that COM1 error if I try to open on a port that does not exist.
Are you definately using a straight through serial cable? (pin2->pin2, pin3->pin3 and pin5->pin5).
First i did not use any cable, i connected the plug directly to computer com port (removed some parts from plug to be able to do that), later tried with 1:1 cable. Also opened the plug to be shore that everything is correct there... yes it was. In a minute i'll try it with another computer.
EDIT: Tested it withanother computer. In fist startup i did not get the error message what was linked in first post, but got the second one (it was @default COM3 and data rate 19200) I changed it to COM1 and 9600, closed the program, opened again and no error message at all...but still no connection:( Changed computers com port to COM5, same in megatune but still no responce!
I have tried many many variations...what should i do next?
EDIT2: Form uploadfirmware i get this error:

If you get a connection and no response, go to File and check that the entry Offline does not have a tick mark next to it

No, it has not. In lower right coner is in gray font CONNECTED (when offline then in gray OFFLINE) , but it should be in black.
I get the same error screen if I try to upload the gauge firmware to a VEMS ecu.
Re-reading things... the correct speed for the wideband gauge is 19200

How to upload it then?
QuoteRe-reading things... the correct speed for the wideband gauge is 19200
Tried this speed also, still no connection.
The only info I have on recovering from a bad download is on the wiki:

If that makes any sense to you.
Nothing.... nothing at all :( what possibly can be the problem when gauge itself works fine... but no connection to the computer is possible??? I`m out of any ideas for now... I think there is nothing left to test anymore :(
The gauge works fine even though you have this problem with connection?
Who did you get the gauge from?

Correct, I intalled all things to car and tested that EGT shows temperature and when lambda connected it showed around 20.0-20,2 in free air (currently WB lambda is disconnected and the gauge shows - - -), now I needed to configure it to send out NB lambda signal to stock ecu and then discovered this problem.
QuoteWho did you get the gauge from?
From Estonian Vems distributor.
I was going to suggest that you try to reset the firmware - but I dont think that its going to resolve anything.
Best to fire the Estonian guy an email and direct him to this thread. With the best will in the world I can't support everyone on my own.
But I'll continue trying to help where I can.

Now I tried to connect when computer was in safe mode and last with third computer... no change :(
Yes, I contacted with seller and lets see how we can put it to work.
Firstly, computer witch I used first time, has problem with com port or windows. Secondly, computers what I tried later, I tried them with adapter cable and I checked it and guess what... it`s not 1:1 cable >:( Now I opened the plug to connect it directly to computer and connection established :)
So, all the problems were just coincidence of many bad things...
Lesson learned, check one time, check second time and when needed do the same third time.
Well thats a good result then.
Have fun with the setup ;D
Hi, i've got the same problem, that megatune can not connect to the egt gauge..
i've tried it on 2 pcs:
- vista with onboard rs232
- xp with usb to rs232
and with both i have the same problem..
when i select the right com port and data rate (19200) and hit test, it just says no response,
but when i open the terminal, it says "booted" when i switch on the gauge..
any suggestions?
Quite often this can happen if you're using the wrong MegaTune software, or if MegaTune is set to offline.
hi rob
well, i used this one: http://www.vems.co.uk/VEMSTech/VemsMT1.0.78rc2.zip (http://www.vems.co.uk/VEMSTech/VemsMT1.0.78rc2.zip)
and the mark next to offline is not there..
just tried to switch it offline and online.. no change..
That one is for the full VEMS ECUs you need the one for the wideband & egt gauge:

I hope this helps
Rob
that was the problem! wrong software!
thanks for helping
