If its the cheapo one, I'm sure a few people here who have one can email you it.  Its awful software though, so don't expect miracles...

If its a small unit, just a large plug, then its cheapo.

If its a larger handheld unit, with LCD and keypad, its the real thing, and valuable :y

Almost certainly a dumb question but, having read the various posts in this and other threads, I have noticed that one of the main requirements for some of the 'cheapo' readers to work properly is a serial port. I also notice that most modern laptops/notebooks don't come with these as standard.

This made me start looking for notebook serial port accessories and I came across this.

Can anyone tell me if this type of thing would work? If so it may be of use to those who have one of these readers but are struggling with USB connectivity.

I'm tempted to give a PCMCIA serial port a try. If it's a pukka 16550 UART or whatever connected to the bus via PCMCIA it stands a lot more chance of working than a USB adaptor with creative drivers. I've had several problems with USB serial adaptors, and on applications that use it as a standard serial port too, rather then bit-bashing the handshake lines as the cheapo Tech2 does. >:(

This is cheaper:

May well have a 16550 compat chip, but due to PCMCIA implementation, may not exist on standard i/o ports (likely wont), hence reliant on software layered drivers in same way was usb to serial adpaters.

I am trying to get a PMCIA serial port to work at the moment with Hungarian software, presumably the same version.

This is on a 98 elite, so not OBD2.

So far I cannot get a data stream, have started to look at the lines on the 16 pin connector with a 'scope. None of the pins that are able to be connected has an output.

The last thing I tried was a 10K resistor from ground to pin 6, some information says this wakes up the ECU for communication.

The resistor certainly gives the correct voltage level on pin 6, +5V, but no pulses visible.

Wil keep trying  on and off, but does anyone have any ideas?
