my car was tune during the summer time and now i have a harder time starting my engine during this time of the year. anyone know what i can do to make it start on the first turn like before. i have to step on the throttle now to get it started. i dont want to pay for a dyno service just to fix that part. i have s300

 

Tweak the cranking and post start fuel tables, raise or lower the numbers in that table at only the temperature you are at now

 

You shouldn't have to pay for a re-tune for such a simple issue.
Don't be scared to call your dyno tuner that you paid to tune your car for such a simple issue. They should be able to resolve the issue for you or tell you how to resolve it.

That is called customer service & it should be included with your tune...

 

k, it get around low 30's in the morning. which do i raise and lower? im not so sure

 

you'll have to try both realistically...and see what works best.

 

Thumbs. They can't logically warranty it since the conditions didn't exist during the time of the tune, but if they take any pride in their work they'll make an effort to help you.
