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

[rob@vems.co.uk]

If you say no to Terminate MegaTune what happens?

You may find that you have to change the comm port in the MegaTune setup

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.

[rob@vems.co.uk]

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:


But it is on COM1 and still no connection. I tried to change computer settings and ports... nothing test button says no responce!

[rob@vems.co.uk]

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).

[ranz]

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:

[rob@vems.co.uk]

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

I get the same error screen if I try to upload the gauge firmware to a VEMS ecu.

How to upload it then?

Re-reading things... the correct speed for the wideband gauge is 19200

Tried this speed also, still no connection.
