My pc running xp wont see my megajolt. It says com1 one not connected or there abouts.

Any idea's?

I have a straight through lead by the way.

baud rate?
something else using the comm port?

Are you sure it is a stright throught lead, as i brouht one, and on the pack it said stright through and it wasnt.

Also the port might not be comm1 try all of them which are avalible

One more thing, if your using a power pack for power, try a battery, as this messed my megasquirt up

My mate tested the lead its definatley a straight through. Hes an IT man but hasnt got a spare minute for a while and i want to gett the proper map on it.

I only have one serial port and nothing was on it before.

Try uninstalling the port in windows are re-installing.

Also double check you have the right version of software to talk to the MegaJolt.

I take it that you have installed the java comm API software? As per the notes here

I had to use a crossed lead to see mine !

Dam thing. Iv tried all that java stuff etc and it still doesnt work. It says "unable to open port com1 Unknown serial port"

Itl connect to the unit using that hyperterminal thing so the port works.

When you say it connects with hyperterminal what do you mean and how do you know it can see the unit?

I followed this

and it does what it says it will.

Most likely a java problem , did you install it from the self installing package on the CD? I find this usually works straight away but did recently have a problem and found that it was loading the wrong version of Java, as i had two versions installed somehow, check the properties by right click on megajolt tune , it should be something like this "Crogram FilesMJLJ TunemjljTune-2.0.3.jar"

Sorted. Just uninstalled all the java i had on my pc and let megatune install the one it wanted and away it went.

Think i had conflicting java's...
