1KZ-TE = engine
ECU = Engine control unit
Its not a fully mechanical engine as it seems to be - its drive by wire with map, air temperature and coolant temp sensors to optimise power output.
When I saw the shershah people selling 1KZ engines or 2L engines with a fully mechanical pump with no LDA to up fuelling on turbo boost - I felt like kicking their teeth in. When asked about how would it fuel on turbo boost - they say
Turbo ghoom raha hai - hawa maar raha hai - buss, lena hai to lo warna nahi lo. STUPID. I always got a cheaper deal because I did not opt for a "desi install of injection pump"
