Issues with the idle valve
I need some help from the AEM gurus.
I've been facing issues with my car's idle valve. It works properly for the first few minutes and somehow it stops responding after a while. I originally thought it had to do with some kind of heat soak but I'm not convinced that's the case any more. If I park the car for a little while and then turn it on, it works fine for the first few minutes and then stops working again. Can anyone tell me what may be going on? Thanks |
Open up the Parameters under the Idle menu.
Does the Idle position change at all? |
Post your map up and I'll have a look at it.

I'm trying to upload one of the AEM files and I get a message saying "invalid file" |

Dustin, the map I sent you allows me to use the A/C while the car is not too hot and the only other issue I constantly face is when I decelerate and I'm coming to a stop. Quite often, the car will stall and shut off.
Thanks, |
Mine does the same thing. Did you end up figuring this out?

As I told you in my pm; a local mechanic suggested that I adapt a solenoid to control the A/C. I still haven't found one I could use. |
I hate bringing up old topics, but I am having the same problem on my AEM EMS. I am working off the base calibration file adjusted for RC 550cc (3ohms). Everything is fine until the water temp gets around 150F. If I blip the throttle, it idles at 2100 rpm. Unplug the IAC, and it returns to a normal idle. I have sent a few PM's, but I was going to see if anyone had solved this problem? Thanks.

pm replied. Connect to AEM PRO. Open the idle template. 2 tables called: "Idle Target Base table" and "Idle % vs Target Table" will appear. I have my first one set at 1,000 rpms lowering to 900 once the temp reaches 190. The other one (Idle %) is the one you have to play with. Shoot me an email and I'll try to help you. FWIW; I never had a problem with my car idling if I didn't turn the A/C on. It was that part I was originally trying to fix. |

Did you setup the Idle % vs target table? |
Thanks guys. I will start there and see what happens.
|
I had that problem, changing the Idle FB Below parameter from 1800 to 2500 solved it.
|
Yeah. After talking with a few others thats what I need to do. Weather and timing have kicked my butt lately.
