I am trying to get my buddies 2g running. He swapped in a built 7 bolt longblock with hks 272's. the car will not attempt to idle unless the biss screw is almost all the way turned out. If i screw it all the way in and do a 1 1/4 turn out, i have to hold the gas down and it will start sometimes. Ive tried 3 different iscs with no luck. In ecmlink no matter how i adjust the biss the iscposition is at 100. I checked the ecu and nothing is burnt. Did a boost leak test and nothings leaking. Fuel pressure is 45psi, 660cc injectors, speed density. He is not running an iat sensor so i zeroed out the sdtempweighting table. If i unplug the isc there is no change. I checked spark, fuel, compression, made sure the map sensor is wired correctly, checked ignition timing, checked mechanical timing, and made sure the injectors were dialed in. Anything else i should try before i go ahead and delete the fiav and isc. I dont want to do that but he is at his wits end and wants the car running.
