ECU reporting wrong temp, No closed loop

[fixkick]

it needs the correct ECT, and yours i bet is wrong.
so you bought one from suzuki, GM or from a store (general auto) ? gosh hope not autozoned. with dura-junk parts..
the scan tool must read 180F for 180F stat.
and be near 300 ohms,
that car can sell (in no rust, and runs great) for as much as $3000 here, used,
and highly coveted car in canada, (goes anywhere any time)

good luck to you, !!
my ECT cost me $25 at the ROCK. (or at NAPA or other great stores)
