Hello I'm having issues tuning idle and start up:
On start up it shoots to about 2500 RPM (at 16 AFR #danger) then tapers down to "idle"

Which leads to the bigger issue idle.
I've been doing the Idle Valve test and I don't get much change on Open. On closed I get different resuts each time especially when I restart the car (650-1100). Some times when I end the test the idle goes to 1400.

The first time I did the I got the idle right between 850-800 by adjusting the p and I gains but when I started it again I got these issues.

The fuel tables have been tuned to naturally aspirated 1.6 but I haven't touched the ignition table which is still on a turbo Map.

 

You may need to decrease the crank to run taper time. Also try the 3.4.3 code; this seems a bit less likely to "spike" the RPM on startup.
