I believe you misunderstood my post.
The pulse from the 555 timer is to replace the VSS signal.
This is to make the ECU think the car is going X MPH not the actual speed.
The drmiller is partly right, increasing the idle air will cause the ECU to decrease fuel to lower the idle, but only to a point.
The ECU has a minimum setting it won't go below. I got a good lesson in this when my IAC valve went bad. Thought for sure I had an intake leak. Couldn't get the idle down. But it idled smoothly.
Now, if you depressed the MAF reading so it didn't know about the extra air...........
Under load this could swiss cheese a piston, not like I've ever done that while on I-95
EDIT:
My god man, I just realized we're talking about a Honda !
Check the tuner sites, there's a few cheap programs to re-program your fuel maps.
Hond decided not to encrypt the computers so anyone can rewrite them.
WOW, way past my bed time to have missed that.
