Cold start idle drops right away for a second
 

Hey guys, I'm having a bit of an issue with my cold start, it starts right up but the rpm drops right away but then goes back up to normal idle. I have been trying to change some settings with the afterstart and other stuff but I just can't seem to figure it out. I am really new to this and still haven't really grasp all the functions that would get this idle drop solved. I have attached my current tune and a datalog from this morning. Please let me know if you have any idea on what can solve this issue. Any help will be appreciated. Thank you!

You max idle duty on the closed loop idle settings page is 30, and your cranking duty is much higher, as is your base values table.

Increase your max idle valve duty to start with. Go with 80% to get the full possible range.

Looking at your tune, I would agree with dann, but you should run the IDLE VALVE TEST, and see what your max idle valve duty actually is. (CAN bus/Testmodes - top right of tunerstudio), I find it unlikely that 30% is the actual open limit.

I would also change your crank to run taper, start at 6 and see how it reacts, this should give it a little more time to settle before transitioning to the run position.
Your closed loop initial values don't look to crazy, but your max is 43.1 in the lookup table, higher than your max open setting, this may cause some issues as your limiting the max to 30 which is your 825rpm area according to your initial value table.

Thanks for the info guys, i'll give your suggestions a try. I will try to do the idle valve test, I thought that the tuner I used set it up but I'm not sure if he actually did.
