Yes you can map your car via the OBD socket, mine was done by superchips this way - its the way most re-maps are done.

However you'd have to be INSANE to re-flash your ECU with a program costing 4 pounds from Ebay.

What proof do you have that these maps/programs have been tested properly? The chance of your car/engine/turbo/ECU being permanently damaged is pretty much a certainty!!

Ask them what warranty they offer when your car blows up?!

has anyone got a guide to the way i would do the re map please? im going to try it on a mk3 golf tdi 1st then if successfull move onto my passat b5 tdi se

I dont think you can re-flash a mk3 golf, you'd need to solder a new chip into the ECU. I dont even think Mk3's have a proper OBD port to be honest!

The Golf 3 post 95 has the port but you can’t flash them. Be very careful what you put in the Passat, many engines have been wasted recently by amateurish re-mapping.

then again i might as well leave it to the pros lol
