Redtop sr20det runs completely fine on the stock ecu. I put a rs enthalpy ecu into it, 550 cc injectors, and a z32 maf. Getting code 55 on the ecu which means everything is good. The car idles at 10:1 or richer, breaks up under revs, wont rev past 3k sometimes, goes up to 5k sometimes. Any ideas? It ran fine before and it is tuned for stock timing and fuel pressure.
