Thanks Roland il look into it further and keep you updated

I use a genuine tactrix 2.0 cable and no iv never used it on this vehicle mate it has been previously tuned with hp tuner by someone else iv spoken to this person they said that they have not put a tuners lock on it all so it's a custom harness for the turbo barra to patrol and yes iv used my cable on many other vehicles with out an issue just never used it with a custom harness in a patrol conversion

Hay Roland its a 2004 xr6 turbo ba btr auto pcm in a y61 patrol its previously been tuned with hp tuner and it dose not have a tuners lock on it mate

Hi there I have a barra swaped patrol I can connect to forscan through the pcm but everytime I try to read the pcm with pcmtec it comes up with UDS error all of my software is upto date on my laptop it's been tuned before to allow for the conversion
