Its called the FITV (Fast idle thermal valve) Its a simple little thing like this that can cause a lot of idle i This is 1 of the common issues with a Honda. Its called the FITV (Fast idle
Running the PWM idle air valve in open loop, my AC Idle-up settings are as follows in the Startup/Idle>Air Conditioning Idle-up>menu: A/C Idle-up: on Idle-up Output: off Idle-up Input: PE0/JS7 Idle-up polarity: Low Idle-up delay: 200ms Idle-up min RPM: 300 Compressor delay Since Last On: 5s Idle-up Duty Adder: 7.4% It works.
Did the lean drop yesterday just with the Idle mixture and idle speed. I have a 87 fj60, smogged, with ac. I got the idle to around 700rpm. Felt great. turned on ac Idles at 1500-1600rpm. went to adjust it down to the factory 1,000 RPM. got it there. turn off ac, and reg idle was to low
Then there is the official idle speed adjustment screw. There is an AC idle up solenoid mounted on one of the valve covers. When this solenoid is activated, it bypasses the throttle plate and runs up the idle. And last but not least, there's the power steering idle up valve. On the power steering pump there's two hoses that run to the throttle
Remove any IAC control (unplug the motor from the harness) and slowly close the blade position until the engine barely runs near the desired speed. Reinstalling the IAC harness lead should result in a more stable idle. This prevents the IAC from leaning to either a fully open or closed static position.
The Idle Up feature is the lowest priority between it and PTO operation. If at any time during active Idle up the PTO on/off switch is activated the control will be given over to the PTO feature. For example, if the idle up is active and the idle speed has been set to 1400 rpm s and then the PTO on/off switch is activated the idle speed will

but have you told the Speeduino the input pin to use for the switch and its it routed to a pin in the ecu.
Right now my solution is to adjust the idle up a bit to compensate. And that does mean that me cars runs at about 1100 rpm at idle with the A/C off, and drops to about 800 rpm with the A/C on. I thought about some sort of idle solenoid, but I am ultimately going to replace the Rochester FI with a Rochester EFI conversion system, so I'll just
Male. The idle speed variation during the warm up is working properly. From cold start it reaches 1100/1200 and start to drop as the engine warms up. My idle speed with Drive engaged its pretty steady at 650-700 rpm. Just gets messed with the ac on, dropping to 470-500 rpm.
