over side note
there exist very FEW professional electricians who can rewire an ECU for 1UZ-FE coupled to an automatic transmission with an LSD
@babarhyd has recently witnessed an (NCP) 2013 LC taken away to butchery at price of scrap because of messed up wiring which was replaced quiet few times but engine dies as soon as shifter is moved to R or D.
