Mercedes A45s stage 1 & dyno

Absolute weapon in today, Mercedes A45s AMG in for a stage 1 tune.
Being a 2021 model, because of anti-tuning software updates, we wernt sure if we could tune the Bosch MG1 ECU.
But we managed
 
 
 
Also Mercedes are now all running the CPC units ( an overriding ECU) which has hidden torque limiters, on this occasion the CPC was agressivly limiting torque and power at 5,000rpm (see dyno plots)
 
Thus I think robbed of around 30/40bhp, but still overall very very impressive. Once the CPC's have been cracked, we will have this customer back to unlock the cars full potential!
 
449 > 484bhp
545 > 656nm
 
gains of +35bhp +111nm
 bench tuned
