Title: Some newbie/beginners questions Post by: Chris123 on August 12, 2014, 10:02:10 AM Hi,
i started to tune my first own file. I've read some basics here and in the wiki. But i can't found a "how to start" or something else for beginners. By the way i spent a lot of time for reading "Bosch ME7 Funktionsrahmen" and some wiki articles. What i am looking for is a short description how to start tune, particularly which maps to change first for testing/learning. My goal is to learn the backgrounds of ECU-tuning and not only copy out from a pattern. I will start by changing map by map and try it directly in the car, because i will see the effects of each map. For myself learning-process it's not good to change many maps at the same time. And that's my problem. I don't know if it's possible to change only a small amount of maps. Not for daily driving, only for testing/learning. E.g. changig LRDXN, KFLDHBN without changing KFMIRL, KFMIOP, KFZW, KFZW2, LAMFA, KFLDIMIX and so on Title: Re: Some newbie/beginners questions Post by: nyet on August 12, 2014, 10:25:44 AM I don't know if it's possible to change only a small amount of maps.

Sounds good. If i change only LRDXN in steps of about +20 with driving every step to see the result, is it possible without changing something else? Is there a risk running to lean without changing ignition and something else? And what will be a proven sequence for changing maps? Which maps should i change step by step after changing LRDXN and LRDXNZK?

After that, add some boost via LDRXN! Title: Re: Some newbie/beginners questions Post by: Allabout on August 12, 2014, 06:34:40 PM Some great info to start with in this thread.
Can't wait to get to play with this. Title: Re: Some newbie/beginners questions Post by: fknbrkn on August 13, 2014, 06:35:18 PM i have many questions
lets start: how to me7.5 512k narrowband ECU make fueling on wot?

I don't understand the question? Title: Re: Some newbie/beginners questions Post by: fknbrkn on August 13, 2014, 11:10:57 PM I don't understand the question? wideband ecu saw realtime AFR and changes injection time to match specified value. closed loop i guess but narrowband sensor cant see 12 AFR for example, so how it make a rich fueling right? Title: Re: Some newbie/beginners questions Post by: ddillenger on August 13, 2014, 11:45:28 PM That's why you have to ensure your fueling is right on narrowband. You log, you adjust, you log, you adjust.
FKKVS, KFLF, KFKHFM. Any combination of them is capable of altering AFR in either direction to better match requested. Title: Re: Some newbie/beginners questions Post by: fknbrkn on August 14, 2014, 10:05:19 AM what i should to log ?

Maf voltage => Maf ariflow => load => KRKTE => TE with many corrections... Title: Re: Some newbie/beginners questions Post by: ddillenger on August 14, 2014, 10:16:32 AM what i should to log ? You need a wideband in order to dial in WOT fueling on a narrowband car.
