BMW 530d e60 remap problem

Postby sando » Sun Sep 10, 2017 3:00 pm

Hi guys, here I will post .ols with my ori and remap so you can have a look. The problem is that obviously Im missing something (limiters etc.), there isnt any difference in turbo pressure, smoke etc. If I set higher rail pressure at lower IQ-s Im getting it, so I think the rail maps are correct but when its set like in this file i doesent rise above 1600bar I assume because i didnt get more than 60mg/str and thats the problem. I think Im missing some torque limiters and boost limiters, so if someone could have a look and help I'll be very thankful. The "remap" isnt good I know but its only for testing purposes, once I see a difference I'll make a proper remap but for now I'm just testing so that i'm 100% sure i've found all maps I need. I lowered lamba a lot, increased drivers wish internal torque limiters a lot and nothing, im getting desperate , so please help. :yawn: THANKS :crazy:

P.S. I know there are few more SOI maps but i'll deal with them later

cef52; cf07c Are those 2 torque limiters ? I increased them and done some logs - guess what: 61mg MAX 1600bar rail MAX 2500mbar boost MAX 499nm torque MAX. Anyone ideas? :cry: :cry: :cry:

Thanks for the reply!!! The DPF is off from a few months but i should increase those anyway right? The z axis is torque?

Also aren't those torque limiters only for the biturbo engine? What means compressor bypass open/closed? Are those maps 21x8?

UPDATE: The car is now remapped but there is a large IQ drop from 3700 to 4000rpm. IQ drops with about 20mg/str in that rpm range and the torque decreases with 100-130nm which feels really bad especially on 4th gear and up... Drivers wish, lambdas, torque limiters, everything looks OK but the IQ problem still presists. Can send logs if someone wish to help...
