Starting Idle

Post by Turbokart »

Hi all Just a question but is there a way of rasing the idle rpm a little bit on start up. Once its warm its got a perfect idle it just sounds like it needs a little help from cold.
I dont have a idle control valve its just running 4 TBs.
It starts well from the cold start map. Sorry if thisnis a stupid question.
Thanks

Under Idle Controls - RPM vs Temps and use Advance for idle control as opposed to IAV. I believe that should work. One question though - when selecting 'use advance' certain figures turn RED - why / for what reason?

Set a warm idle with relatively low advance.

Then when cold use higher numbers to achieve a higher idle speed

To indicate that they are now ignition related, not IAV related.
If you have 100% max duty, and then turn on ignition based control, you now have 100 degrees max advance.

As your warm idle is 10, open the throttle a little so that the engine needs 4 deg, the system will work much better then
