Hi. I am a student . I am at the beginning in remapping. I want to learn to find MAP-s. I manage to find my first map,but i am stucked. I can t find the axes for the map int the rar file. It s my first map so if somebody could explain me how to find the axes it would be very good.I made a new topic because if someone help me i would post more questions so everybody could learn from them. Sorry for my english,i m new at english learning too. ;))
Thanks in advance.

Hmm, that`s looks like an EGR map, but without ORI file i can`t tell you more :)
Factors and offsets most of time you can grab from other damos from similar ECU`s (Generally only address differs).

Upload your original file and put link here.
Basically you have few types of maps. Some of them are 8 bit maps (256 values possible)and some of them are 16 bit maps (65536 possible values).
But those 16 bit values can be HiLo or LoHi (Byte2-Byte1 or Byte1-Byte2).

Generally, turbo maps are 16 bit values.

Hi. I uploaded in the atachment the original file from a marelli 6jf ecu. Could someone help me to find the egr and egr switch map?
I try to find them but without succes. Thanks in advance,Regards,Veress Levente

Hi. I have a problem. I hope it s not a stupid question but i observed something. I first learnd finding maps on a vw golf bin. I observed that before the map you can find the map size(8x8) and the axis values. Now i m trying to find maps from my cars ecu wich is a marelli ecu. I can t find the same thing on marelli ecu. (i posted a picture from vw ecu). Info before the map helped me alot to find maps.So my question is:1First of all. Do i was right with the vag ecu? 2.Will i find the same thing before marelli ecu or is just for bosch?3.Is there something before marelli maps that can help identify exact the map?Thanks in advance.

Hi everybody. I l find in a thread that:A map starts with MARKER,after that the nr. of colums and the valus for x axis and then the nr of rows and after that the values for y axis. This is correct for marreli ecu or only for BOSCH? I only find this valid only for Bosch ecu. Correct me please if i m wrong,and tell me if is there something like that for marelli ecu's. It help's me alot to find maps. Thanks in advance,Veress Levente
