Title: ME9 Coldstart Idle Target Post by: bamofo on March 24, 2020, 11:58:04 AM Sorry for my ignorance but it seems like my q7 has a high idle target on Cold start that doesnt NLLMG / NLLMGFS. it wouldnt bother me except as i remove Torque limiters on the car it introduces a surge when you start the car and put it into reverse, similar to what my wife will do when she drives it... It does it a little stock... but not as bad when you remove some of the limiters.
Can someone share the Table name i should be looking at? or should i try forcing the flaps on the intake closed all the time at idle regardless... Ill keep playing around and digging into the definition i have... But its hard to produce since its only when its cold. 09 Audi Q7 4.2FSI for reference.

Title: Re: ME9 Coldstart Idle Target Post by: bamofo on March 28, 2020, 04:45:56 PM What torque limiters did you remove? The ones i have played with so far are KFMOF / KFPZU / KLMIMAX / then slightly rework (KFMIRL / KFMIOP) Mostly just the last couple rows though. Im just missing a target coldstart Idle that it does during its initial routine. I dont know the Keyword for it... Once it does its thing and idles down the problem goes away. Im looking for control over coldstart a little bit better. Seems during this time period it hunts between the coldstart idle target and my requested idle targets (ingear / notingear) Title: Re: ME9 Coldstart Idle Target Post by: IamwhoIam on March 29, 2020, 12:43:02 PM You do realize that idle speed, cold start or not, does not depend on ANY kind of torque limiters of any kind?
Title: Re: ME9 Coldstart Idle Target Post by: bamofo on March 30, 2020, 07:22:57 AM You do realize that idle speed, cold start or not, does not depend on ANY kind of torque limiters of any kind? Yes, what i noticed is that since i removed the torque limiters it seeks harder between the two Idle targets. If i change nothing but the torque limiters, it does this. So my question was, is there a startup initialization Codeword i can use to figure out why its targeting higher Idle on cold start so i can control what it does. probably due to Cat warm-up / SAI and so on.. Just asking for a pointer so i can dig deeper, please. Title: Re: ME9 Coldstart Idle Target Post by: fknbrkn on March 30, 2020, 07:45:24 AM KFNLLST
But that's are not the reason of your problems Title: Re: ME9 Coldstart Idle Target Post by: bamofo on March 30, 2020, 09:20:53 AM KFNLLST But that's are not the reason of your problems Thankyou, After looking at the two tables for (park) vs (in-gear) I noticed an Activation table - KFNSKHLL Turning that off gives me full control of the startup now. Thanks for pointing me to the right area. |
