That ecu isn’t for that swap you need to get it chipped and tuned. Your running a 2.0L with gsr Head that’s not made from the factory. The ecu you claim is virgin and is made for a sohc vtec (correct me if I’m wrong) 1.6L or 1.5L or whatever... you need to send your ecu to phearable or whoever can chip it and then order a basemap chip for your setup and then take it to a dyno shop to get it tuned.
