Default High Idling Problem

I just finished up my turbo miata. I have a 1993 1.6 miata. I put a t25 turbo on it, flyin miata manifold, rx8 injectors, and a 255 lph fuel pump. I also have it running on megasquirt ecu. I got it started and it was running great and idling fine. I went out to drive it and it was going well but i noticed that at a stoplight while idling, the idle would not drop down. It would idle at around 2200 rpm which is not good. But before I drove it when I just started it it was idling fine. I did not tune the fuel yet however it was on the base tune. Not sure if thats the problem but i don't know. Is there anything I need to play around with in megasquirt to fix the idle? Thank you

Tune the fuel, spark, and idle. First, confirm that you don't have an air leak.

Read up on the tuning manuals. Your question is pretty much, "I haven't tuned my car yet, do I need to tune it?"

In the future, all Megasquirt related questions should include which Megasquirt you have, which firmware it's running on, a datalog, and your tune attached.
