Hi can anyone tell me how long the Cold Start Trim stays on for and what temperature brings this in as i cant see any reference to that in the help section. Say I set it at 10% does this mean that it gets an extra 10% on top of what extra fuel is applied via coolant adjustment for the given temp in the table.

Thank you.

adding 10% will give it an additional 10% over any other compensations.

double post.

Many thanks for that can you tell me what actually triggers the cold start fuel trim is a set temp and how long it lasts for, eg is it a 30 second addition of fuel ?

Thanks again.

It is determined by the temprature and lasts until the temperature rises to a safe operating temperature.

Thank you for replying Spunkster. I may be asking a stupid question but I cant see what the temperature level is that triggers the cold start fuel trim is it adjustable in a table if so can you kindly point me in the right direction.

Many Thanks.

No this is not adjustable. I do not know all the factors that trigger a cold start condition.

Thank you. I will experiment with the Cold start fuel trim then.

If I find out anything more I will post back in this thread.

Once again thank you for your replies.

Is there anyway of boosting the Cold start RPM?

For example.. When in stock form, The motors will start and rev up to about 1500-1700rpm then as the motor and ECT rise, the RPM's decrease.

When I installed s300, I've never been able to get the tune to do the same thing. When I start my car, It idles around 400-500 rpm and then gets higher after about a minute or two of idling.

Any way to fix this?
