Most OEM senders used we measured can have a variation around +/- 15 degrees, but the needle shows no change as the ECU is happy since the reading is in its acceptable range. The Water/Oil/Trans temperature sender I supply error range = 2% or +/- 2 deg

I look at water temp, oil temp, oil pressure primarily,
and then also do trans temp and diff temp. The trans temp is never a problem.
The diff gets warm.
I also log AFR, revs and throttle position. When I rob the box off the other race car,
I'll log 2 g's and steering position as well. (Innovate LM1. It's old, but it works)
The logic on oil temp is to be nice to the motor- it takes a LONG time
to warm up, and unless it's 'green green green'
then it's not a big challenge to softpedal it just a bit until the temp comes up to
operating.
Also, I had an air pocket (or something) in the oil system once, and my cooler didn't work
for the first oil change. So I was seeing 250- 270 f at first in cool ambients
when I was nosed under someone.
Drain and refill (same type of oil) and now never see much over 220.
Anyway, that's what I do. Fuel pressure's smart to look at... but I don't, yet, as the
AFR doesn't show problems.now, sometimes I just mess with people. It's more entertaining that way. george graves
