Title: What am I doing wrong? Post by: JavaCrash on December 21, 2023, 11:35:41 PM attached is my log. Full bolt on b5 s4 with 83mm maf, 630cc injectors, walboro 525 fuel pump, yada yada the full works, anyways Im really struggling to read my log and figure out why in any gear on a WOT pull my wideband reads completely fucking rich, and in 3rd gear it really breaks up bad,but I can't think of why, KRKTE is set to the calculation on the wiki, TVUB is set to the values I found through a datasheet, and my maf was scaled by 29% to start from stock. I've replaced all evap, wastegate, and n75 lines due to cracking etc. So I do not believe it is a hardware issue but I don't know shit. Any help is appreciated. Sorry for the google drive link, log was too big for the forums.

B_lambts B_tabgbts I dont know how they are called in a S4 file because i only do 1.8t. Title: Re: What am I doing wrong? Post by: JavaCrash on December 22, 2023, 08:00:04 PM I will try to log b_lambts as you said, but I have my EGTs coded out in my tune and unplugged.

Neither of those values have anything to do with your EGTs.Title: Re: What am I doing wrong?

It seems that lambts is activating immediately, how can I figure out what is causing them to trigger? Title: Re: What am I doing wrong? Post by: prj on December 24, 2023, 02:55:13 AM would this not be measured from the EGT? if not ill log it, hopefully will be able to tonight. No, start reading. The only module that has anything to do with physical EGTs is ATR, NOTHING ELSE IN THE ECU.Title: Re: What am I doing wrong? Post by: prj on December 24, 2023, 02:57:41 AM how can I figure out what is causing them to trigger? By opening the FR (Or the Alfa English ME7.3 FR) and looking at the function diagram for the LAMBTS module.You're not gonna tune this car over the forum dude, you need to learn to read the ECU documentation to answer your questions. Everything you're asking is right there black on white. Title: Re: What am I doing wrong? Post by: terminator on December 24, 2023, 03:59:55 AM DLATRNLN

Thank you again, my TABGBTS was set to 750c, i set this to 950c so I don't have to worry about it. Title: Re: What am I doing wrong?
