Hi. I have been trying to tune a Case Puma 170(2012) but its been unsuccessful so far. The ECU is Bosch EDC7UC31. I have no problem reading or writing the files but they keep giving me check sum error 3158 and going into limp mode. My file editor has checked and rechecked the files but they keep giving check sum error after about 5 minutes of driving. I am using a genuine Alientech KessV2 too and its all uo to date. I load the original file back on and its all OK again 5 minutes later.. Has anyone come across this before or does anyone know how to rectify it???
Thanka in advance,
PS I have tried uploading the files but the site is not allowing them.
