new to vems. failing at first hurdle

[Hutchie]

i have been running my car on a link ecu, but to cut a long story short it is borrowed. so i purchased a vems ecu.
and so far i just cant get the laptop, using serial on back not a usb converter, to talk to the vems box.

how do i know what version of software i need to talk to the vems.
how do i know what firmware is on vems if i cant talk to it.
and how do you upload new firmware??

thanks in advance
Hutchie

thanks but i have already read that, and printed it so i can follow it @ car, i simply cannot get the laptop to see the vems

Are you 100% sure you have.

12v and ground at the vems.
correct serial connection
correctly selected COM port?

Where abouts are you?

[Hutchie]

im in the north east of england, i bought this vems off mini-valver (dave) you may know him

That ECU should have firmware v1.0.73 on it.  You may have problems with newer versions trying to connect.

Have you tried swapping the tx and rx wires into the ec18 plug?

[Hutchie]

i thought it was plugged into that plug???

Did you make the harness?

Or are you plugging into the LCD connector?

[Hutchie]

the harness came with it

Now that is really strange - the cable is a straight through pin 2 to pin 2 and pin 3 to pin 3 isnt it?
