Hello.Anybody knows where I can find and download the software update or flash for my ecu? Also would a cheap scanner like ancel ad410 with laptop connectivity is enough for the flash/update?
You need a factory level scanner with the update software to flash/update the ECU.
And that’s the dealer.

Exactly why do you want to update the software?
Are you trying to fix a particular problem?
If so, why are you so sure a software update will fix it?
I have a p0304 missife for a while and I replaced a lot plus checked a lot and I am thinking maybe it’s just an ecu issue
Thank you for that information . . .
Personally, I think the software update won’t fix your #4 misfire
spark plugs and ignition coils, I presume?
you checked for spark?
compression test?
is #4 injector being pulsed properly?
As for that injector, have you at least verified that you can hear it’s clicking at idle?
have you checked injector resistance, to make sure #4 injector isn’t open circuit or shorted?
injector balance test?
no rat damage to wiring for #4 coil and/or #4 injector?
