I was highly recommended by my good friend Tony to buy X-PROG Box ECU Programmer. He informed that I was quite lucky because the device has resealed to the latest version V5.48. The XPROG-box is a professional ECU chip tuning tool which projects a continuation of the project XPROG and now supports more than 450 units (serial EEPROM`s, Microcontrollers (MCU), Electronics Control Units (ECU), DashBoards, Immobilizers, Calculators and others). I was kindly noted that it can only work on Windows XP computer system and I must close all anti-virus software before connecting the device with my laptop. Otherwise the device would be damaged.
Tony said he had bought several items from www.xcardiag.com/ before. They offer professional technical service and fairly reasonable price. Tony warned me that if I try to use other version software (lower or higher) or try to update software or hardware, the hardware will be damaged. And the warranty failed. That is to say, I can ONLY use the CD software from their wedsite.
I think I had better do some work on their website before making a big decision.
