Title: Timing @ idle Post by: vwaudiguy on March 16, 2015, 08:00:35 PM Is this straight from kfzw, or is there another map/ correction factor(s) that modify kfzw? It seems it changes also when the clutch is depressed..This is why I think there is another map.

Title: Re: Timing @ idle Post by: vwaudiguy on March 18, 2015, 08:55:23 PM Thanks for the info, guys. I looked in a few different bins for the values/axis of that map, and read what I could find in the FR. I still have some questions.
1.) What do the values in KFMRES represent? 2.) Is the ecu targeting a load value, and then gets it's ign timing from that? Basically looking at KFZW I see high values in the 25-30% load range and 800-900 rpm range, and see 10-14 degrees of timing @ idle, and was wondering why. Title: Re: Post by: turdburglar44 on March 19, 2015, 10:49:07 AM The way I think about it is this; the throttle plate is not precise enough to target such low loads by itself. So to remedy that the ecu is allowed to undershoot it's torque target by an amount up to the values in kfmres/kfmresk. If you set those maps to 0 idle timing = kfzw.

Do you know what the values in those maps refer to though? Title: Re: Post by: ddillenger on March 19, 2015, 08:33:55 PM Thanks for the response. Do you know what the values in those maps refer too though? Percent? Title: Re: Post by: vwaudiguy on March 19, 2015, 08:39:18 PM Percent? Of? I was a little surprised the FR didn't say a lot, or maybe I didn't understand because of the translation. Title: Re: Timing @ idle Post by: Rick on March 20, 2015, 04:02:21 AM of torque

What else could it possibly be a percentage of? Certainly not cheese. Although..... Cheese IS delicious. Title: Re: Timing @ idle Post by: vwaudiguy on March 20, 2015, 09:34:26 AM I love it when you bust my balls, D! :)
Title: Re: Post by: turdburglar44 on March 20, 2015, 03:25:21 PM Idle cheese. Mmmmm
Title: Re: Timing @ idle Post by: ddillenger on March 20, 2015, 05:34:34 PM Just a bit of good natured ribbing :P
Thanks for not taking it the wrong way-lol. Title: Re: Timing @ idle Post by: vwaudiguy on March 20, 2015, 05:39:39 PM Never! ;D But I still don't know where it get's it's timing values @ idle :)
Title: Re: Post by: turdburglar44 on March 20, 2015, 08:32:34 PM There's some sort of idle timing pid I'm guessing. Kfzw is it's upper limit and kfmres calculates it's lower limit? seems legit...
Title: Re: Timing @ idle Post by: ktm733 on March 21, 2015, 07:16:46 PM How do you zero in on this idle timing? Woth e85 I'm nessing with timing but i can't get it stable
Title: Re: Post by: turdburglar44 on March 21, 2015, 08:11:42 PM Tvub and kfmres. I'd stay on stock timing honestly. It's not about what's the most timing you can put in. It's just how much the car needs to maintain idle.
Title: Re: Timing @ idle Post by: ktm733 on March 21, 2015, 09:21:23 PM Look up e85 cold start! Kfmresk and kfmres is the torque reserve at idle. Ive learned if 0'd idle is lumpy if you add i went in increments of 10% this lead to a very nice idle :) thanks turgburg for info! E85= success
Title: Re: Timing @ idle Post by: ktm733 on March 22, 2015, 08:06:08 PM Turgburg finally got the idle problem solved. Like you said i messed with idle timing so kfmres and other map can't recall name I upped to 2.6. Steady idle now!
Title: Re: Timing @ idle Post by: vwaudiguy on March 22, 2015, 08:26:37 PM and other map can't recall name I upped to 2.6. Kfmresk? Title: Re: Timing @ idle Post by: ktm733 on March 22, 2015, 08:37:04 PM Yes^
