Again you changed the transmission type, now you no longer have a large fluid dampening device behind the engine that we have to wind down.This is what I want…
I want the freakin thing to start, cold or hot like a new car.
I want the idle to fall to where it’s set as soon as i push in the clutch.
I want the throttle response crisp like a well tuned carb.
If I knew where to go/what to change w/regard to tuning to affect the startup, i’d have no problem with that.
If I disconnect the iac, and set the idle using the throttle screw, i’d expect idle to remain static, not wing up and settle, then surge maybe, maybe not like it’s doing now. From there, I’d have no problem with that either.
A soggy throttle blip, i can live with.
The idle valve is not the only idle control you have going on... its still setup in closed loop idle, so when it engages closed loop it thinks it needs to wind down from XXXX rpm to a stable XXXX idle speed. It will do this with timing control as well.
Lets change a few things.
Your tune is likely still setup in closed loop, lets make it so that the idle valve just moves to a set position at each temperature. This will allow you to control the idle speed based on coolant temp by altering how far open the idle valve is. Larger number = more air at a given temperature... the Ford IAC valve is basically fully closed at 35% Touch NONE of the other settings on this page just what I have highlighted.
Now lets go to the Idle Warmup Duty table and make some basic changes to the table on the right. You dont have to alter the curve with dots directly, you can hit the little button on the top right of the graph to bring up the table like I have on the right and punch in values. My suggestion is to start altering this curve with the engine full hot or back the idle screw down a turn before you begin. These values should act linear from 40% to 80% so you can figure out how much rpm a 5% change will give you fairly easily.
Now this says closed loop but its for timing control to help stabilize the idle where you want it at. The First thing you should do before you fire the engine up is set this curve to the RPM you want for each temp. This WILL NOT affect the idle valve in open loop bit it will affect the TIMING.
You can disable this by turning off all the settings un the Idle Advance Settings
This curve works with the curve in the photo above to control the idle speed based on engine temperature. its pretty self explanatory it lowers or raises the timing to reach the target you have in the closed loop curve. The settings in this the way it is right now are very aggressive.
Let me know if you have more questions, take care of this first and then I will explain what to alter in the startup settings.
