I have 3 different sets of phase 1 or 2 chips. One is EDS ph2 copy, one is custom phase 1.5 and one is genuine CCT motorsport phase 1 (last one is 100% form a running car). None of them works in my ecu, EML doesnt light up, engine wont start. If I change top chip for original and leave bottom as it is, engine starts, car drives like stock but I get ecu fault code (faulty). If I swap bottom for original and leave top uprated, car wont start either. Chips are correctly positioned, 10 times checked. Car runs fine with original chips, no errors. As I understand bottom chip is for boost control and top is fuel, ignition etc. It's hard to believe that all 3 sets are faulty. ECU is without immobilizer PK code.
