Hello,
i already noticed that before in demo mode , but if i filter the ECU i want to scan by car model ( like X84 or X84Ph2 ) the scan only lauch for trigrams , per say : X84 will work while X84Ph2 not, i tried different models in demo mode, and it was the same (dummy data only shows with trigrams ).
Though i noticed , my car ecus ( some ) shows up with a X84 scan because they can be included in multiples project as i could verify in the ecu/db.json
Is this the intended behavior ?
Update :
after a bit of hacking , i found out that it is due to these line in ecu.py : projname = proj[0:3].upper()
used when parsing database either ecu/*json or ecu.zip or xml files , so it appears 3 times in the code.
as of now appears at lines :
for json files : 1238
for ecu.zip : 1282
for xml files : 1344
if i change it with for exemple : `projname = proj[0:18].upper()` the dummy scan works
though i don't know the impact, so i will wait for an answer here before trying with my car.
