So i tried to write map on my golf 4 1.8t with a kess clone, no errors when writing but car doesn't start.
I used nyet me7check and gave no errors on the bin i tried to write. Now i cant write anything with kess, i get wake up error and in recovery it says error and asks if i want to continue. Also i tried to connect with vcds to engine and i cant.
Is the ecu completly dead or can i flash it in bootmode with galletto cable? (And if it's dead, what did i do wrong?)
* I attached the bin i tried to write and what i got from checksum
The file is missing checksum blocks and it looks like a multiple attempt of running it through the 2 step auto patch scrypt. Either way the file has code patches in the wrong spot, overwriting checksum blocks and most likely the cause of the ecu brick . Ive ported your files calibrations to a virgin original file of the same software version. Also, included is the original hex and a2l if you want to take a look. Ether way the ported file is safe to write with all checksums good to go. Although it seems you may have bricked your ecu and will need to flash it on the bench in boot mode. Lucky for you kess supports boot mode flashing so you should be able to recover it without an issue.
Some things to note:
Deletes are done wrong (error class bits changed only, prokon and eskonf sare stock.) Looks to be a rear o2 sensor delete attempt. If you actually unplug the downstream o2 sensors with this tune you will lose long term fuel trims. Its only hiding codes now its not actually configured properly for the missing sensors.
Crackle pop attempt won't really work as minimum ignition angle table is stock and only optimum timing and base timing changed. Also, changing base timing will cause massive timing sways that you will feel in the car too.
As far as the actual calibrations... meh, it shouldn't hurt anything... Timing at full throttle seems to be a bit aggressive so you may wanna be sure to run high octane fuel. The file will not have 2 step as I only ported the calibrations of your original file.
Lastly, I hold no responsibility for the calibrations of these files as they are not mine and I really don't agree with some of the changes.
Hope this helps, If you have any questions feel free to ask on this thread.
