good morning.
no the ecu can not control engine temps, the RAD + thermostat does that. and is working
the ECU reads the ECT as a voltage, and A/D converters that to binary data. called dac counts.
the ECU sees it as a voltage and then looks it up in a table. for ECT and translates voltage to temperature.
if forget if i did that exercise,???
let me look.
id bet the engine is 180f. and the ECT is 300 ohms (it is) and the dash is at mid scale, (it is) and the ECU is working, and it is reporting 180f but the software. is wrong. (rhinoman software and co.)
the ECU always uses the ECT as verbatim. it only uses fake ECTs reading if IT fails. only.
i cant speak for backup-mode, its not documented on earth.
in limp home the bad sensor is mimicked. simulated in a very very crude way, either a fixed number. or is scaled crudely
say you unplug the MAF.
the ECU then creates a virtual maf, it uses RPM and and the TPS angle as very crude maf, (modeling )
the designer set the model to rich side on purpose. so as not to burn up a good engine.
the rhino scale is wrong, they may have used a wrong plug in table at compile time. id bet this, is it.
i did play with the ETC once.
here is the voltages I read.

and the Ohms law math, there.
my 1996 has a 2000 ohm pull up to 5vdc. (i reverse engineered that fact)
and this allowed me to calc. volts at the ECT side
the FSM does state the 158F critical temp from cold engine mode to warm up mode,
0.6v hot. (meter across ECT) the 92 to 1998 ECT is same p/n sensor, so this voltage it good.
one more fact coming.
how many ECTs were used on engines. G16.? or even G13>
ill look that up easy.
keep in mind he, is in UK . and runs, UK Vitara's that have many forms,(suzuki type codes) all that is can look up easy.
more later
smoking gun
all of ours are 61b00 ECT sensors. on 8v engine and 57F00 on all 16v up to 1998.
UK market code E02.
the UK engines are called type/2/3 for 16v and uses the same sensor.
type 1 engines there use 61b00 or ever other odd sensors.
so you need the the software for UK Suzuki SE416 (vitara code) Type 2 or 3 engines. or SF310 or SF413(swifts)
Im not sure who to contact but id join there forum and ask for type 2/3 software for ECT.
