Default Really high idle when cold....wtf is up with that?

I've had my chipped p28 from Xenocron for a while now. It runs great...but when it's cold, it idles at 2 grand lol...when the motor warms it idles at 800 or 900 which is right where I want it. What would make it idle so high when it's cold? Is it anything I could change quickly if I opened the map in Crome and then reburned it to the same chip?

well yea my old p2p ecu did it too but not at 2 grand. It only idled at like 1400 when it was cold before I got the p28 chipped. And it's rich as fuck before the motor warms up too, but I think that's normal. Not the 2 grand part though. It's not really a big deal. It's just annoying as hell. I have to let the car sit and warm up for like 10 minutes before I drive lol

it's normal...2k is kinda high, but the ECU has a high performance mod to it...and BTW, you don't ahve to wait for the motor to drop down to normal idling to drive it...you can still drive the car with it idling at 2k, hell you can do it 3k...just be careful not to slip the clutch to much...

Isnt that the FITV? Letting small amounts of air through, and coolant while the car warms, and once warm it will close and begin fully operating off of the IACV?

Open Loop = high idle, no coolant flow to help engine warm up, extra fuel being dumped to aide in the warming up process

Closed Loop = idle comes down and normal everything

AS long as it comes back down i think it is fine. The car is COLD.
Mine does that also. You have a problem if it is at 2K all the time and after warm up.

You could open the map up in the latest version of crome (1.1., then click on tools, then Advanced Tables.

You should see an option for idle speed vs ECT...this is where you make these adjustments.

That's because you have power steering. Turning the wheel increases the load on the engine, so the idle blips a little.
