EFI gurus; any thoughts on how I can accomplish a commanded fast-idle to be used in certain off-road situations?
I have a manual 5-spd transmission and would like to have an ability to bump the engine idle up in order to 2-foot drive the brake/clutch and have enough RPM to maintain momentum over an obstacle (those of you off-road guys know what I’m talking about). I know there’s secondary throttle cable options out there, but what I’m exploring is how to make this happen at the flip of a switch. Is there a way to manipulate the IAC in order to bump throttle? What about leveraging the AC circuit to fool the EEC into thinking the AC compressor is running and therefore bump the idle?
Here’s my configuration:
Anybody actually done this or have a proven approach?

Here’s my configuration:
- 302 motor
- Mustang 5.0 EFI (mostly all stock)
- A9L (variant) computer
- Explorer serp & accessories (no AC)
- Painless EFI and chassis harness
