Default AFR problems, someone please help! - 05-28-2020, 01:10 AM

Hey whatís up guys, Iíve attached a log here for you guys. Iíve been getting AFR lean off my JB4. I saw that my HPFP Dropped pretty low on this log, not sure if my LPFP is causing my HPFP to not dump enough fuel. Please help me! Also been misfiring under load only on cylinder 3.

Few things -
Enable 6cyl timing.
What fuel? and are you using a BEF?

Sounds good!

N54 BimmerBoost MHD Back End Flash Maps - N54Tech.com - International Turbo Racing Discussion
Can be found there ^ if you need help.

Upload the Pump BEF, and relog 3rd gear map 1.

What are your other mods?

So i uploaded a new CSV file after doing the BEF to my car.
Once again it AFR Lean and cut boost.
The weird thing is i swapped injectors and spark plugs and coil packs from cylinder 3 and im still only getting it from cylinder 3.

I can't see the CSV try re uploading it.

*edit: Just kidding you replaced the original.


Did you set the jb4 to 4/2 on the dash?

Your HPFP looks tired. Is it original / how many miles are on it?

Also, are you getting any codes? o2 sensor ect..
