Yep i'd think so. If you really want to use your own cable you could try getting a genuine FTDI usb to serial as they are known to work with stock settings out of the box. I ordered a cheap FT232RL USB to TTL on ebay. I read you just tie the RX and TX and works at 8192bps. Probably not genuine thou...

If its old enough that its a genuine 16550 chip behind it then it will. If its a built in usb to serial then itll be no different to needing a compatible usb adapter. Ok thanks its not an old laptop and it has a smsc lpc47n237 io controller in the dock for the com port . I think that my problem then

Ok I will try diode flip. I'm using a serial port on the dock of my dell laptop. It has 9600bps as default speed in device manager but i assume it is able to use 8192bps if software requests it?

Unfortunately i am still having the same issue after building max232 cable. :hmm: I use the schematic http://www.techedge.com.au/vehicle/aldl8192/8192hw.htm. I left out resistors r2 and r3 cause my vy series 1 v6 doesn't have those pins on the car. Is that right? Wondering if i got wrong setting som...

thanks didn't have any luck with flash tool it was just waiting for heartbeat and wouldn't connect. Have a max232 so will try build a cable with that instead.

I have VY commodore and I built 2 transistor ALDL to serial cable and using 1.05 adx file from this site. when I use tuner pro rt it connects and makes tune on car but all the data showing through the software is all random and its not indicating any data errors. is this common with 2 transistor cab...
