I've just come across a 97 Prelude. I've been after one of these for a while and this one is top notch apart from one issue which as the title says. Its currently immobilised. I'm told it needs a p28 Ecu with a h22 map to function again. Does this sound right? if it does does anyone know how I might go about sourcing one of these? And how much this would be. cheers in advance
