I didnt see a number. The bar almost filled the entire screen. Yeah after idling the car heat soaked in the 50s on the power fc. I monitor intake temps already. I need a oled commander because its hard to see this thing haha.
So far she's running good, but then again the problem didnt rise until the next day. I haven't driven the car since I first did the idle learn. I have plans to pull the UIM and disable double throttle as well as pull off the ISC and check to see if its in spec since the commander shows nothing about it. |

Nope everything , speed , knock , water Temp , intake temp , rpm's , boost , injector duty on the commander it will have the regular real time nuimbers and on the side with a little blakc box with a highest value of the sertain criteria , it will stay there until you shut hte power off , next time go ahead nad give it a try . you will know if your car is over boosting , your highest knock , so on. |
Will do. So good idea for me to clean the ISC? Or test it.
|
Didnt get to clean ISC yet but problem is still there. No change. Car runs perfect when power fc is first installed. Next time car is started idle surging comes and sticking.
First day idles 850 perfectly. Now it won't ever touch that. |

I doubt a line is off. They were just replaced with silicone and I'm pulling 17" of vacuum. Won't it be less if a line is off? ISC settings are stock.
|
Looks like its irratic again. Driving home I set the first F/C setting to 1050, rest is untouched. Now it goes to 850 when it wants to. Doesnt do the surging but when coming to a stop it does go to 850 briefly and jumps back up to 1200. Idling is always around 1k and sometimes goes down to 850.
There seems to be no steady symptoms that will help me figure it out. |

Their all at the stock parameters. I believe stock is 750 with no load and I'm not seeing that at all.

if your car refuses to idle at those parameters something is letting air in thats not supposed to , weather it be a bad check valve or a loose hose or the ICS itself |

Change the others lower them all , my tach reads higher then the pfc

I figured one of these days it will fall out .. but nope.. bad decision , when I brake hard or accelerate hard you hear that socket Hah |
Haha I have yet to drop something down there. I will say that I have dropped a bolt or two on top of my radiator that I finally found after doing some work and removing parts.

Okay I disconnected Isc. Started the car and no high revving when starting. Stayed at 750. Drove around and idle is mostly at 750 but sometimes 850 and then 1000. No load on car. Idle never above 1000 though.
|
Your problem is probably throttle body setup.
thewird |
How do I go about fixing that? Everything was perfect with the stock ecu. So I don't know what needs adjusting.
