Hey guys. Recently (out of pulse buying) i bought two items from Ebay. Item numbers 230151827724 (ECU Remapping+OBD Software) and 130136463306 (KWP2000 ECU FLASHER CHIPTUNING INTERFACE OBD2) does anyone have any experience with these products or anyone got any advice on if i should try it or not? Now that i have them i'm afraid something might go wrong if i try it.

The simple answer is if you don't understand it then don't touch it. You could get yourself into some trouble if it goes wrong. A Briskodian recently had to pay somone to sort his after an accident with similar equipment.
