Hi,
I have a full bench read (Modul 71) of a Seat Arona 1.0 TSI CHZL (95 hp stock).
ECU details:
Bosch MED17.5.21
HW: 04C 907 309 AT
Bosch: 0 261 S17 501
Processor: TC1782
Goal: Clean Stage 1 (~135-140 HP / 230-240 Nm)
Based on the unrestricted 115 hp CHZB factory maps (same hardware: turbo, injectors, internals).
Request:
Increase Driver's Wish + Torque Limiters
Raise Desired Load / Boost target (~1.35-1.55 bar)
Proper full load lambda (~0.78-0.82)
Keep ALL factory protections intact (EGT, component protection, knock, etc.)
