DPF Companion

• CarPlay cold launch — tap the CarPlay icon to connect and see live data without opening the iPhone app first - takes approx. 30 seconds to connect to OBD. • Accurate time remaining — uses real observed soot build rates with no artificial caps, persists across sessions • Regen threshold precision — exact values from your vehicle's regen history (e.g. 5.98g, 24.02g) • Companion device improvements — faster auto-connect, handles accessory power gracefully, last-value-wins for thresholds • Snapshot card — always shows both soot % and time remaining arcs, updates immediately at trip end • Fleet insights — regen fuel impact comparison, route matching for repeat journeys • Bug fixes and performance improvements

• Pay What Is Fair — voluntary support option in Settings. Help sustain continued development if the app is useful to you. • Vehicle Alerts — smart notifications for regen approaching, regen predicted, fuel efficiency changes, and device sync reminders. • Multi-vehicle support — automatically tracks multiple vehicles when connecting to different cars. • Improved trip recording — device-recorded trips now survive power loss and display correctly. • Fuel efficiency accuracy improved — readings now closely match your vehicle's dashboard. • YOUR VEHICLES section in Settings shows engine code, vehicle name, VIN, and activity dates. • Bug fixes and performance improvements. • If your engine code isn't listed or DPF sensors aren't detected on first connection, the app will let you know and offer to contact support. The following engine codes should be supported, although compatibility depends on the ECU software version installed in your vehicle: CAAC, CAGA, CAHA, CAPA, CAYA, CAYB, CAYC, CCWA, CDSB, CFCA, CFFB, CFGB, CFGC, CFHA, CFHC, CFHD, CFJB, CFWA, CGLB, CGLC, CHNC, CJCA, CJCB, CJCD, CLAB, CLHA, CNHA, CNHC, CRBC, CRKB, CRLB, CRMB, CRUA, CSHA, CTBA, CTEC, CUAA, CUDC, CUNA, CUPA, CUSA, CUSB, CUTA, CUUB, CUWA, CVUA, CVUB, CVUC, CXBA, CXEB, CXEC, CXFA, CXGA, CXGB, CXHA, CXHB, CXHC, CXXA, CXXB, CZZA, DAUA, DAVA, DBGC, DCBC, DCBE, DCXA, DDWA, DETA, DEUA, DEUC, DEWA, DEZE, DFBA, DFCA, DFEA, DFFA, DFGA, DFHA, DFLA, DFLB, DFSB, DFSD, DFSF, DFYA, DGDA, DGDB, DGTE, DGTC, DGTD, DHXA, DJGA, DLUB, DMGK, DMMA, DMZA, DMZB, DNAA, DNAB, DNAC, DPXB, DSRA, DSRB, DSSA, DSTB, DTNA, DTPA, DTPB, DTRA, DTRD, DTRB, DTRC, DTRE, DTSA, DTSB, DTUA, DTTA, DXBA, DXNB, DXRB, DXRC.
