Auto nedokaze byt bohate / chude. ECU to podle lambda sond vzdy dorovna na stochametrickou smes. Pokud to dorovnat nedokaze, rosviti se check engine.
Jak jsem psal, na fuel trimy pouzivam OBD diagnostiku (scanmaster) a zda se, ze long fuel trim odpovida parametru FRA. V tvem pripade to je tedy 4.6% obohaceni... tzn to zni OK. DTV korekce nevim co presne znamenaji, odhaduju, ze to jsou korekce (mrtva doba vstrikovacu) na volnobeh, na startovani by to nemelo mit zadny vliv, tam by mel mit vliv hlavne ten FRA. Parametr integrator asi odpovida short fuel trimu.
Ten obrazek realtime hodnot jsem tam dal, aby jsi mohl porovnat stav na ohraty volnobeh - delku vstriku / pozici skrtici klapky (prozradi vacum leak, treba od toho separatoru), atd.
Logy startovani se musi delat tak, ze se zapne zapalovani (jinak je ECU mrtva a diag se nespoji), spojis diagnostiku, zakrtas si parametry a az zacne logovat, teprve pak nastartujes.
Jen ze zvedavosti, plyn v podlaze, motor 4500-6000 rpm, lpg te v tehle oblasti nedela neplechu? motor tahne ok?
Jsem z nymburku / praha
Edit: tady jsem vyskrab z logu komplet hodntoty asi z te doby co jsem delal ten screenshot a jeste pred tim nez se 'prehral' motor. Jak jsem koukal do tech logu, tak mam pocit, ze me nefunguje nizka rychlost na vetraku
