Nearly ready to install bodies on my 205, loom is built up, got a base map, DTASWIN installed on desktop PC (haven't got hold of a laptop yet) USB to serial adapter purchased, up to date Drivers installed from Prolific website. ECU powered up with a battery reading 12.6v, fuel pump relay primes fine. I get this error: I have checked which comms port the USB is connected to, DTASWIN is pointing to the correct port. I am connecting through a POT box I have made myself which saves buying or making a specific lead, would be so much simpler if they used an USB connection. I have confirmed pinouts to be correct through the box
