Title: No Connection to round V2 via vemstune
Post by: tds.lurker on July 10, 2020, 04:01:06 pm
Hi

I have a big Problem:
I cant connect my round with vemstune.
I tried it with the normal serial port of my PC and also a Usb to serial converter.
All value like COM Port, Baumarten, etc. are correct. Vemstune and Even Megatune cant finde the gauge.
I want to connect it, because the gauge changed from lambda to AFR all alone.
Is it possibel that there is something broken?

Thx for help

Regards
Timur

Bytes received: 320                     bytes sent: 320

Connect via hyperterminal or other similar terminal agent and see whats coming across from the unit.

looks like you have mixed rx and tx, I remember it had some cable with it which was like adapter and had mixed rx and tx, dont remember is it needed to connect to VT or to ecu, if you are using it, remove it and I believe vemstune should connect it fine

I have already switched Tx and Rx- no change  :'(
