I have an RB20DET in a Laurel Medalist C33. I changed the chip in the ECU and replaced it with a Marobi Stage 3 Chip..Since i put it on the check light on the instrument panel keeps blinkng and the engine is not working well at all...
Can anyone help me with this problem?Could it be the chip was installed wrong?Or did something go wrong with the electrical wires on the ECU board?
Does anyone know if these chips are good?
