Thread resurrection here! I've converted my obd1 corrado to obd2 and am using an emulator to bypass the ecu immobiliser. When cold my car starts immediately. But when warm it also takes an age to fire with a prolonged crank. Ignition switch is fairly new (vw) leadss are new (bbt) and there are no errors via vcds (except 06688) which didn't come back after clearing, running and rescanning. Welcome any suggestions.
