I have all of my closed loop idle stuff turned off in the attempt
to root out the surging and cold-start stalling.
Now I see that cold start is asking for a high (~25 g/sec) airflow
(Desired) with the Base about 16 (for temperature) but the actual
is still down about 10-12g/sec.
I am thinking this must be a discrepancy in the effective area vs
IAC counts. IAC is "live" and bopping around in the 200 range but
the air is coming up short (STIT, LTIT off). I do have an epoxied
TB that is drilled to 3/16" or 1/4" (I forget) in the IAC port.
Do I have it right, that Desired Airflow should determine an effective
IAC area, then IAC counts by that table? Is Desired the "real" target
for airflow at least?
I think I'm a gonna drill me some epoxy out, since I am allowed to
be out in the garage tonight. See if that brings actual into line with
desired.
