i'm having great fun with cold start mapping my ECU. as i didn't get a dyno cell for my birthday, i'm adjusting the mapping most mornings when i go to start the car. its gone from needing me to hold the throttle half open, and cranking for around 5 seconds whilst it coughs and kicks, to starting on the key (but then dieing if u don't put a tiny amount of throttle on). once i get the idle control valve in, that should cure that. quite suprised at how well it starts with a 5deg ingition advance. small engine, high cranking speed normally needs 20ish deg
