Guys,
For those that are currently running hondata system, do you usually have hard start when the motor is HOT/COLD, post your problem if you have one. And what could be causing hard start with hondata syste? Could it be the crank setting in the hondata software that needed to be changed? I have a b16a with hondata s200, i always have hard start issues. I have DSM 450 injectors install, help me out someone?

 

Lower the fuel trim of the cranking adjustment. If that doesn't help then try increasing the fuel trim.

 

You should have no problem with hard start at all. I start the car here (in Canada) in -20C & lower temps and it is perfect. Try working column 1-6 of your map from 450 - 1550rpm (to find out exactly what columns need work, datalog startup and you will see which columns your ecu is using, etc.).

Also look into the cranking fuel adjustment, as was said earlier. Usually you will have to go a little lower, cause the rough start could be due to excess fuel, etc.
