these are the live data cold. ill test the maf using your method with multimeter. ill post results after test. thermostat on order from suzuki. fitted new temp sender for ecu, (2 wire or 1 wire. 2 is correct )

old one looked pretty ruggerd. the oxygen sensor is swinging lean to rich. i just screen shot live data. the maf dropped to 0.2 v to a maximum of 2.3 v. so ill bench test it

so far I am looking at all that and see nothing wrong cold engine ECT shows 21C so that is good but what is ECT hot. 82C is correct.
idle fast idle RPM cold looks great at 1261
advanced looks good.
looks good so far.
maf at idle is 6g/s  ,nomral.
The maf seems to swing ok , up to 2.3 is near 3v,  (takes   aggressive WOT to get 3v)  max MAF output us flying up a hill wot say in 3rd gear, hard.]
in fact max MAF out will be 95HP full HP.

TPS 0.6v is good near 1v is great at idle.

just make sure ECT rises to 82c or more if have the extra hot stat, at 90c.

fuel pressure needs to be verified ok.  It should be ok, but you never know for sure. unless checked.

good luck ! and cheers.
