hey guys need help i have a fully built b20vtec i am running uberdata. I wanted to know why everytime i start my car it never starts on the first time it always starts on the second turn. also my car smokes alot at idle but driving is ok but when i come to a stop alot of smoke I am thinking i am running to rich on idle plz any help would b appreciated

 

put the cold enrich to 100 that will solve your starting problems. You just need to tune idle for it not to run rich. Keep taking out fuel until it starts to stumble or pop a lot (lean misfire) and then add like 10% fuel and you idle will be set. Don't mess with any other fuel values thoug because you'll need a wideband to do those
