No piggyback boxes and no\nadditional hardware — the original module is retained, OEM diagnostics keep working, and\nthe tune is fully reversible to stock.\u003c\/p\u003e\n\n\u003cp\u003eIn standard form the Gen 5 Haldex coupling sends roughly 30% of available torque to the rear\naxle under acceleration. It can reach 50%, but only reactively, once the front axle has already\nstarted to slip. This software rewrites the control strategy so the rear axle is fed a full\n50\/50 split under acceleration, and does it proactively rather than waiting for wheelspin.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat it changes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTrue 50\/50 front-to-rear split under acceleration\u003c\/li\u003e\n\u003cli\u003eQuicker torque transfer response\u003c\/li\u003e\n\u003cli\u003eTorque split no longer tapered off at higher road speeds\u003c\/li\u003e\n\u003cli\u003eRevised launch control strategy\u003c\/li\u003e\n\u003cli\u003eSwitchable 2WD mode, assigned to a factory drive mode of your choice\u003c\/li\u003e\n\u003cli\u003eOptional live tuning table — set pump duty against road speed and throttle position\u003c\/li\u003e\n\u003cli\u003eRuns alongside any existing ECU or TCU software\u003c\/li\u003e\n\u003cli\u003eDeveloped within the factory tolerances of the Haldex system\u003c\/li\u003e\n\u003cli\u003eFully reversible to stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eBecause the coupling spends less time slipping its clutch pack under load, the upgrade also\ntends to reduce the amount of clutch material that collects in the Haldex pump — a common\ncause of pump blockage and reduced rear drive on these cars.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eModule compatibility:\u003c\/strong\u003e Haldex controller part number 0CQ 907 554 X.
