Title: Lambda and Me7.1.1 Post by: b4A4nowA6 on June 14, 2015, 11:18:10 PM Phila_Dot said........" Are you basing this on wideband data? Or logging a target AFR variable?
Lambas will follow the richest input." That was in relation to someone having issues meeting requested AFR. Well I was looking at my log and the LambdaProtection value (klfbts i think) is reading SUPER rich. and I am thinking from the reading I have been doing that I can/should tune KFLBTS for wide open conditions. If I recall I have my EGT's coded out so changing this values wouldn't have any effect on being a safety table correct? Title: Re: Lambda and Me7.1.1 Post by: ddillenger on June 15, 2015, 09:57:24 AM There are several schools of thought for fueling, and how you approach it should be entirely setup dependent.
Post the details of what you're working on. Title: Re: Lambda and Me7.1.1 Post by: b4A4nowA6 on June 15, 2015, 10:14:00 AM Well I was looking at my log and it seems that my fueling AFR desired starts to follow the the profile with the lowest lambda value. I am not sure about if it is actually reading that low or not but I certainly do not think I want a lambda of 0.65 anywhere unless i am on e85. So I already have tuned via lamfa so now I am thinking of triming my lambts to be just slightly richer ( around 0.80).
I am using OEM RS6 turbos with 730cc ev14's. I was getting a lot of backfire upon deceleration when it is hot outside as well. Not sure if its related.

You don´t want 0,65 lambda even in E100 ;) Title: Re: Lambda and Me7.1.1 Post by: Lost on June 15, 2015, 11:20:37 AM If you are running e85 you should not have to tune bts at all. Set the bts trigger on 800 and do you fueling based on lamfa. Not reacher than 0.80. I have done quite few e85 tunes spec on oem RS6 turbos. Best power on 0.82.
Post your file i can look at it. Title: Re: Lambda and Me7.1.1 Post by: b4A4nowA6 on June 15, 2015, 11:41:14 AM Thanks for the input guys, to clarify.... I Will be going e85 soon but wanted to work everything out with 91 first so I can go ahead and smog my car.. Then get a new pump so I can go e85.. That being said, I have attached my log .cvs in the first post.
Also.. Thanks for putting me in the right direction for e85 :) |
