when the engine is cold as in not running for hours or days, my car is hard to start, takes 2 tries to get it started and then when it does...it takes a minute to clear out the fuel. idle is no issue, just really stubbon to start.

What part of s300 do i adjust to fix this...im know the tables...and adjusting fuel and timing and such so normal tuning is not an issue...but ive never really dealt with cold starts..and whenever we tune...obviously once its warm you just tune the car and worry about cold start later.

Have you checked to make sure your battery is okay?

 

no...car turns over without a problem as fast as it should.

 

Never used a s300 but have you tried your Raw cranking fuel and Injector battery correction? These are featured in Neptune

 

whats the afr at cold start?
can you post the map from the car?and a log?

 

Check out your cranking fuel trim first.
If that doesn't clear up the issue adjust your Cranking base pulse versus ect tables.
Also you may need to adjust your post start fuel settings.
All of these settings are under Paremeters/fuel trim.

Good Luck!

 

car is not here right now, just gathering info for when i see it again.
