Misfire problem

Good afternoon
I would like to tell you about my 2018 Subaru BRZ car, 10.600 mile
which I bought at an auction in 2020 in disrepair (Damaged from the back side) and brought it to Azerbaijan ... see photos
Tuned car (Delicious tuning):
Jackson racing supercharger
Flex fuel kit
JDL auto design
Borla exhaust
when I started to drive the car after the repair, I felt a strange smell from the muffler and the car began to choke at 2500-4000 rpm. Computer diagnostics showed problems with 1 cylinder, when I pressed the gas pedal, an error appeared in 4 cylinders. We looked at the injectors and the reel, changed the spark plugs (the old ones had a black coating, which is not normal).
I turned to Delicious Tuning who advised me to change the firmware. When I bought my car, there was no flashing device. Can I use my friend's device from GT-86 or should I buy a new one?

Please take no offense, but if you were to change your diagnostic program's language setting to English, we may be better able to help you.

If it is not flashing it is not ok. Have you gotten the App on your phone to see if it will connect? You can get a replacement from Delicious Tuning, or if possibly fix yourself if you or someone you know is great at electronics. Those boxes are not designed well. You have to keep them completely dry or water will get in and damage them.

I'd buy a new one. This device is connected to the system controlling your fueling, I would not take any half measures.

Yep water intrusion. Yes it can be repaired, however the technical data and ability to test it is not accessible. Better off getting another one.

If your only going to run petrol\gasoline and not E85 then you dont need the Dbox or the flex fuel kit. However you will need to alter the tune so its not looking for input from the flex fuel kit and jist get a petrol only tune.
