Heey its a wired story.
someone called me to make tune for hes car + egr off.

i took ecu back to car, car cranks 5-7 sec before is start , glow plug is blinking , engine fault. and very slow power
i checked files a few times tried with original file, now same problem. i think meybe something is wrong with ecu. i got new ecu made clone with original files, and same problem.
