First tune Bmw e46 320d 150hp

Postby RaresCr » Mon Oct 01, 2018 11:50 pm

Hello guys ,

so i am new both to the forum and remaping , i have gathered many hours of research and based on some other guys style of remaping
, examples and information i found here on the forum and on other forums i've created my first version of stage 1( for my personal car , BMW e46 320d 150hp 2002 eu3 management EDC16c31 SW: 361858) .

For now i went for a stoic of 16.8 with 75 mg of fuel 460nm and 2680 mbar of boost(N75 maps not modified , i want to see how the turbo behaves before i start messing with it) , i did allso extrapolated the duration for 85mg with a rail pressure of 1650bar for the future , calculated SOI based on EOI ( used the EOI builder 1.3 made by Alex T) i tryed to stay within the limit of stock EOI (~6-8 max degrees ATDC).

I will wait for some opinions before i'll flash it to my car , My car has stock injectors , stock turbo , custom 70/76mm stainless full decat exhaust . Please if someone cand give me some advice or opinion about my tune i would appreciate a loooot . Thanks in advance (attached Mod file , ori file and mappack)

So i flashed the tune today and firt thing's first my drivers wish map , the way i've done it, it's a little to brutal (to sensible pedal) and it feels weird , i will redo that , next thing i have a problem with overboosting AAAA LOT , but i had this problem before because of the turbo actuator ( i have to get a new one ) . The car feels more alive , it pulls hard from 2000rpm and keeps on going up untill it goes overboost and my stoic rises . I don't know why it does not go into limp mode , boost map 2680 boost SVBL 2700 and limiter allso but the car goes 3000 and above but the map does not read above 3000mbar. I won't push it anymore because i don't want to blow up my turbo , i will make some changes and come back with news , but please if someone could rate my tune , give me some advice i would appreciate , thanks

Hi mate,
Your mod file is full of mistakes.I rarely saw anything like that.Nothing well changed, i repeat, nothing.Please write back the original file,you will save money for stare parts.
Ai amestecat procentele de le-ai omorat, ai scazut, ai crescut valorile din aceeasi mapa fara nici o logica.Nici o mapa nu e bine tunata, si nici mappack-ul nu e complet.

Minis never die.They just get faster
If you speed up on curves instead of slowing down you probably own a MINI Cooper.

Hello again , i made some changes to the DW and neutral TL for launch control, made a log with testo , and here is the result (log file in archive, .csv file), with some overboost problem , no smoke or barely visible, car pulls stronger than before , no strange or abnormal behaviour. I still have to modify boost map a little bit , i missed something. Please if someone would like to give me some advice where my mistakes are , give more specific details , i am open to critics no one was born taught !! Thanks

Hi mate,
you have not changed anything for a better tune.Look only on DW,Duration ,Turbo maps.In attach are the percentage changes on these maps.DW-some values increased with 260%,Duration 56% increase for 200Bar on rail,Boost map lowered values with -30% in the middle area.Your changes don't have a logic, you just play with the numbers using winols.
Same for the other tuned maps.Please try to find am EDC15 , or EDC16 tuning guide , read and learn.

Adrian , thank you once again for your time and explanation, if you look it that way , lay one file on to another it does look that it has no logic , but i will send you in PM my mod sheet in excel to have a look how i did it , and then maybe you could give me a tip how to do it your way . For boost map , i converted mbar in maf and afterwards in Stoic AFR
, lowerd the mid section for low rpm , because my car had problems with acceleration under 2000 rpm , my ideea was to lower boost(now i've looked ofer the boost maps again and realized i've made some idiotic mistakes) request from 1500 rpm so it would not have to wait for the turbo to build too much boost to inject a certain amount of fuel . On duration maps i have moved some colums to make way for new values up until 85mg and allso eliminated 1000 bar row , maybe thats why it looks so weird . Drivers wish after first failed atempt ( i changed all my maps after a remaping guide [i did send you that guide to have a look] ) because i made "the pedal too sensible" at touch started from scratch and decidet to leave stock up until 15% and go flat from 1000 to 5000 rpm in a ascending way. If i am so wrong , shouldnt the car drive worse? , it realy drives much better, pulls very good from 1800 up until 4200, as i said i will send you in PM some stuff , if you wanna look, thank you once again , i will redo some maps . And come back
