What sort of laptop did the tuner use ?

A laptop with a serial port should be foolproof, it should just connect with no real effort ( obviously select COM1 in the DTA software too )

You say bought a lead....presumably it is the correct lead ? pinout as per below

no idea steve as i wasn't there. obviously i don't know what you mean regarding selecting com 1 on the software,me thicko wood butcher. the lead i bought has 15 pins either end as that is what the ecu and laptop have. all instructions presume that the end user has a certain basic knowledge of computers...well they havn't met me and carl obviously. i can make doors and windows from scratch using hand tools if necessary...now that's easy

ECU has a 15 pin connector, the laptop or computer uses a 9 pin serial port.

The 15 pin connector on the laptop will be for an external monitor.

The lead used is not a generic lead you'd buy in a computer shop.

You'll need a bespoke DTA serial 9way D to 15way D cable - wither from DTA direct or that auction site.

You still need the correct 15-9 serial lead to use with the USB adaptor...

But do note, USB adaptors really can be hit or miss.

I just bought from DTA, not stupid money and didn't want to run the risk of it not working when needed.

With various computer differences, that still isnt a guarantee it will work on every computer.

it isnt really anyones fault if they dont work, it's just there are so many hardware setups out there and then Windows itself has quite a few variations.

I had good luck on my DTA with a cheap £3 USB Converter and Asus laptop. But I also tend to keep a laptop for the car...as once you start installing lots of software and drivers for other stuff, you can start to get conflicts and something that once worked fine...suddenly doesnt.

I've also used some PCMCIA.Express type serial adaptors and they're probably more reliable. Although sometimes their connectors can be pretty crap.
But I keep a few different adaptors for use with various stuff when tuning cars, as sometimes some just dont work, so I keep a few options.

Ultimately if you can get a laptop with serial port that is always best option, especially when you're having comms issues.
