C - Idle Air Delay - This acts as a delay for closing of the idle speed motor much in the same way that a throttle
D - Idle Air Integrator - This value changes the response speed of the IAC motor system. A higher unit value
E - Closed Loop Activation Temp - This is the engine coolant temperature that the ECU will start using the oxygen
F - Rev Limit - Use this field to specify the rev limiter for your engine. Type in the required value and press "enter".
G - Desired idle - Use this field to specify the desired idle speed of your engine. Type in the required value and
H - Duration offset - This value is preset to 55 units. Changing this value results in the same effect as adjusting
I - Decel Wait - If the engine speed is over 2500 RPM and the throttle is released, the fuel to the injectors is cut off
to increase mileage and improve emissions.
seconds, or DISABLED, by pressing "F3" until the desired delay appears on the screen and press
"enter".
J - Ignition type - Either "Holley", "Ford" or "GM" ignition type will be displayed. Select your ignition type by
K - Select number of cylinders - Using F4, select the number of cylinders for your application.
L - Percent (%) IAC opening - This value represents the percentage of IAC opening based upon throttle opening
M - Minimum cold IAC Position - This value, programmable from 0 - 200, is the minimum position of the IAC
N - Decel IAC Position - Position IAC motor travels to during decel. Holds idle speed up slightly to prevent excess
O - Open loop throttle trigger - Programmable value at which the system enters open loop. Value corresponds to

stop dashpot would work on a carburetor. A higher unit value results in a longer idle air delay.
Programmable from 0 to 255. A value of 0 results in no delay, a value of 100 results in a one
second delay, and a value of 255 results in a 2.5 second delay.
results in faster IAC response.

set too low or the engine goes into closed loop too soon, adjust the closed loop
activation temperature.

during the throttle follower routine. A value of 0 would disable the throttle follower
routine, a value of 50 allows the IAC to open to ½ of it's travel when the throttle is
fully opened, and a value of 100 allows the IAC to fully open when the throttle is fully
opened.
