s40 usb/comm

Post by split58 »

have read through a few threads on here but massively confused still, so looking for help...
i bought and fitted the s40 pro ecu all wired up to the vw aircooled engine.
I downloaded the dta Swin version 66.1 onto my laptop, iv got both the pin ended cables and a usb converter cable-neither apparently work, iv also downloaded the prolific converter programme thing and tried changing the ports numbers to 1,2,3.. trough it, still no response.
at a loss to what to do next, both cables were from maplin and not too cheap.
my laptop is saying most of the ports are in use, I have no idea how/why they are!
any ideas would be greatly appreciated, engine runs ok just looking to set up the cold start!

100% foolproof solution....buy a laptop with a serial port.

You need to configure the USB adaptor so it behaves as COM1-4 in order for the DTA program to be able to see it.

Control Panel, System, Device Manager, COM Ports etc

a normal 9pin cable wont be the same pins as the dta cable.

You need to ensure that pins 1 to 5 are connected straight through from the 9 way to the 15 way connector

then your cable is not correct. Comms via serial port is usually pretty foolproof

I've only just noticed this thread so you've probably sorted the problem out by now. If not, you need this:

All your worries should then be over!

This subject has been discussed elsewhere on this site a couple of times previously so you are not alone.
