Running lean logs jb4 fbo
Hey I have a 08 135i AT. Its full fbo with jb4. I had a walnut blast done by Darrel in Antioch (highly recommended). We were talking and he suggested we do some data logging with my car to see how I can make more power. We did 3 pulls and quickly found out somethings wrong. Car is running extremely lean and not targeting as much boost as I feel it should be. Need the help of some of you more experienced guys out there. We think fuel pump possibly? I attached all 3 logs, any info or thoughts would be great thanks. Logs are on Map 5
Also...fp-l ranges are all over the palce..is that normal? http://datazap.me/u/boosthaus/ryan-5-16 Last edited by ryanb122; 05-17-2016 at 02:30 PM.. |

Unfortunately I don't have the software yet....I have a mac book, the jb4 came with the car when I bought it and now im trying to learn about how it works and tuning... Im trying to decide whether to sick with the jb4 or go to a flash tune before buying a windows computer. Darrel has the software so we did the data logging on his computer. Anyways yea I was thinking the lpfp numbers were all over the place too. Sorry for the noobnes but whats FOL?
Im Running straight CA 91oct and no, no back end flash. Quote:

Have you reset adaptations since getting the car? Do you have an iPhone or android device with usbOTG ? You could use jb4 mobile to update everything . I'm definitely biased, but on the n54, JB4+BEF is the best combination. I would t go with a standalone flash unless you want something low power.

No I have not...I Probably should though cause I just got it walnut blasted huh?
And yea I have an IPhone, I don't have usbOTG but I can get one on amazon haha. You recommend I just get the jb4 app and the adapter? and go from there with resting the adaptations? And im guessing BEF is a flash to work with jb4? And yea my goal is 500hp haha...my next mods are inlets and LPFP. Quote:
