Just after a bit of advise really, so i recently bought an 2.5 tdi quattro i realise its a heavy car but it seems to have a real bad flat spot till around 2k.. then the torque takes over and that quattro system is working good at -18 on a thursday morning at 5.30 am. I decided that a car with 320k KM was not worthy of a expensive remap, yes having had a saab 9-5 aero remapped by one guy in the UK who is the forum god for remaps all for £110 this is money well spent but to throw £300+ or in my case euros at a tuner i dont know seems ridiculous as the car is old and i could crash it next week in the snow and then what? So i decided to buy a tuning box off german ebay, an austrian company called kuberl, i've had chip express on a mitsubishi pajero sport it was ok, also dtuk on a alfa romeo also good, so my reasoning is this for £105/£110 including postage to lithuania why not.. a claimed 25bhp increase with a 40/50nm torque increase and a "claimed MPG increase" torque makes acceleration so any increase is welcomed. my problem is the instructions regarding connection to the ecu are not clear. on either of the other 2 cars mentioned it really was a disconnect injector rail plug insert box in rail... blah blah and happy days. But i have never had to connect to ecu before i think its best if i get some help before doing something i might regret.
