B48B20B G30 520i Stock+JB4 Map3 & Map0 Review
1 Attachment(s)
Hi Guys

I just got my JB4 installed a few days ago and logged my first set of WOT Pulls in Map3 and Map0. Unfortunately I had the "combine logs" setting on so all the puils (which were done over the course of 10 minutes or so) were grouped together. The log starts in Map3 and at timestamp 3223 (line 1854) I switched to map0.

Not entirely sure how I should interpret these results as I'm a newb in this regard.

The car is a 2019 G30 520i. Stock hardware, engine is B48B20B (software detuned 184ps version to the otherwise identical 254ps 530i B48)

Thanks in advance for all the help.

I'll try to get some separated logs on my sunday drive tomorrow but not sure if I'll have time to go as o yet.

Note I'm running 98 RON (all fuels in Hong Kong are 98 RON)

No WMI, no E85

Should I be concerned about the high fuel trims and erratic AFR on map3 vs map0?

I’m planning on getting the EWG and FP wires to run absolute boost target 17psi with stock hardware (I’m still in warranty)

Would the above logs suggest this is ok?

You can probably try mailing BMS support with regards to your logs and for inputs? They're usually responsive and Ando helps a lot to dial things in.

Oh cool

Will do that

I thought that's what this forum was for but I'll give them a shot directly
