Title: a little help golf gti mk4 aum
Post by: gigabyte on January 10, 2013, 10:39:17 AM
Hi there
I thought id try a map ( http://nefariousmotorsports.com/forum/index.php?topic=2585.0 )
Just want to make sure I have done everything right
I flashed it with memory layout 29F800
It flashed over ok did seem a little more torque but not massive difference is there anyway to tell if my original .bin is mapped or original stock?
VW Golf 1.8T AUM no real mods as a EBC and the map sensor is clamped
I saved my original .bin file
Thanks for your patience very nooby at this stuff but never learn if I dont try  :o

Read back using the Read function and either do a compare (you are using Tunerpro?) to the original, or just look at the changed map(s).

If you just flashed without looking at what changes you were making, that's not a good idea at all.  This would be a good time to download Tunerpro and start learning...

Thanks for the reply mate
So im better off flashing my original .bin file back and using tuner pro to compare the altered .bin?

Just to be clear, you used Nefmoto software and not boot mode?  If Nefmoto, there's a Read button right next to the Write button.  Read your bin back and store it on your computer.  Nefmoto will ask you for a file save location.  Compare this .bin to either the one you thought you wrote, in which case they should be the same, or your original, in which case it should be different.  In Tunerpro, there is a .bin compare function (double click on the identified difference and the map will open), or you can open separate instances of Tunerpro (Tools>Custom).

Tunerpro is an off-line tool.  You will need both .bins available to look at from your computer.

Really, though, if you wrote a file with the correct name to the ECU and the upload process completed, there is no real reason to suspect that it is actually the original.  Unless, of course, you accidentally overwrote the modified file with the original.

Yes mate used Nefmoto to read my bin before I done anything then saved it. I then wrote the file I got from the link in my post there was no errors the whole process completed fine. Im just confused to that with such a slight difference in torque I wasnt sure if I have flashed my original back. I compared both files with tuner pro and there are differences. Maybe my original bin was already played with my friend says my golf pulled better then a standard one when I first got it. Im not sure but thanks a bunch for the fast reply I appreciate it a lot. Im going to run some Vag Com logs with the file I flashed then flash back to the original one and compare logs.

Try and get set up with ME7logger http://nefariousmotorsports.com/forum/index.php?topic=837.0  Much better than VagCom, and if you want help from any of the experts on here they will pretty much insist on the increased sample rate.  There's a GUI for it that makes it much safer for using on the road http://nefariousmotorsports.com/forum/index.php?topic=1079.0  ECuxPlot (google search) will allow you to easily graph (it does work for VagCom as well from what I hear).
