Hello everyone, i have a 2021 GT4Door 63SE Performance (843Hp version) and i currently have 200 CELL Armytrix downpipes installed and i was wondering if there is any way to unlock the ECU it is a Bosch MG1CP003 or if there is any other way to bypass the check engine light, thanks.

alexhvh

Probably in the US but since i live in EU specifically Romania it’s been out since September 2021

peejalino

Did you find a solution. That ECU doenst seem to be able to modify.. Having the same issue...

alexhvh

not at all seems that no one has been successful in unlocking the ECU

Rondavouz

Only once for a tuning solution I found is Opus with an add on box( 6500euro for 940hp). I dont think it will take care of the downpipe error though, but you could ask them.

alexhvh

Yeah i know about it but it doesn’t work with aftermarket downpipes only original exhaust and it’s not an option unfortunately. maybe in the future it will be unlocked we will just have to wait
