Ish,
Just re-read your original message
Sorry. Mis understood.
If the software isnt reporting comms errors then its the software itself
one wayt or another as Jim says.
XP does impose overheads on serial ports especially when using USB.
If the software hasnt got the latest fixes like that I used to do mine then
it could be that the software is allowing retrys and only if say 1 in 10
data packets is getting through correctly.
This wouldnt necessarily cause error messages to be reported and
shows itself up as a delay.
Really best call the software manufacturer as they are best suited to advise.
I will keep an eye in this for you no problem if I can help.

Andreas,
Unfortunately, it is difficult to look at something like that and give advice.
Best contact your supplier.
USB driven RS232 serial ports are very fussy. !
I personally prefer a true serial port (On the laptop itself or PCMCIA card)
as this presents least problems in all circumstances.
Wether or not this will work is TOTALLY depentant on the ecu software
manufacturer and their ability to use serial drivers in the XP windows
enviroment correctly.
Also, what may work ok for one person may refuse to work for another.
This is the problem of supposidly "compatiable" pc hardware on USB.
(I.E. In the real world, there is no such thing)
If its cheap enough, you may just have to buy and try !
Good luck
