Hello all,

today, I was "studying" the differences between the various maps that I have (starting from the original 159 2.4 JTD 210 HP Q4 365.416 ORI ) specifically comparing the original with the maps, DPF OFF and EGR BLOCK made from Time

If I open the file with a hex editor that does not alter anything, some of the maps in my possession, tested working on the car (original, mapped egroff dpfoff, only egroff manual) have AC B5 02 88

dpf off and egr off that is made by the time they have AC B5 02 88

The other two maps that I had loaded on the machine (the map sucks with the egr is left active, the map sucks with the egr turned off by a second preparer) have different values in 1FDFFC and 1FDFFE but they work

I thought it was the checksum, but if AC B5 02 88 works, because ECM Titanium try to change it? And, above all, how can it be the same between different files?

Mystery!

If you want to place the maps, but is not influential for the purposes of the response. The question is why ECM Titanium change from just the values in 1FDFFC and 1FDFFE . The sequence to reproduce the strange behavior is this:

0) I Open the ECM Titanium

1) Load the ori

2) Load the mod

3) I Look at the 2D to the addresses 1FDFFC and 1FDFFE , the maps are worth the same (AC B5 02 88)

4) I Close the 2D view

5) From the tools I do "Compare file" and that's in addition to the difference relating to the egr or the dpf jumps out also 1FDFFC and 1FDFFE

6) I go Back to the 2D view and this time the two graphs are different in 1FDFFC and 1FDFFE

Why?

however, I have 3 maps with the same checksum and all working how is that possible?

pOlPo85

Type this map that I enclose I've made by taking the original and making two passes with a Time, removed the egr and removed the dpf

The alleged-bit of checksum are valid AC B5 02 88 as in the original map

Do you think it works?

I confirm that if you load a map with the checksum wrong to not part the motor but I can riflashare?

Thanks

normally, apart from the old edc 15, and a few other ecu dated the same interface will calculate the cks in the process of writing.

I have the clonaccio "galletto 1260"

actually when I open the program "NEW SERIAL" and load the file, in the window I calculate the checksum. And is different depending on the files, I don't know if you should give always the same number or not

attached are the two maps: the one with the EGR and DPF disabled by Time and the same map that is passed on ECM Titanium with the checksum changed

pre-ecm: A5 B5 02 88 (like the ori)
post-ecm: A9 FF 5B 81

If I open the program NEW SERIAL (galletto 1260) the map ori (the immaculate conception) tells me Checksum 2364, the "post-ecm" I mark AE92

I do not understand how it works, however I was expecting that all maps with the checksum "correct" had the same result no?

When you select the driver from the cock, you correct the checksum in the car, then you don't have any problem.. same thing that also makes mpps on these ecu.
