Modifry ECT

No, NA with a VAFC tune and bolt ons
Looking at the Helms the fan switch is set to turn on @ 196-203 degrees. The ECT sensor is in the back of the block vs in the radiator, so that would be a 5+ degree difference between the two (cooler at the fan switch). With that it seems my switch is operating right at the top end of normal.
This is assuming the modifry ECT is reading spot on too.

I don't have a Modifry ECT, but I set my Haltech to read out the same as the Modifry ECT on my AP1. I saw five bars the other day in stop-go traffic while running A/C on a very hot/humid day. Sitting in grid at an autox I'll see four bars pretty normally. As soon as I get rolling it'll go down to three.
The five bars made me nervous enough to turn off the A/C while sitting in traffic and just deal with the heat. Was your A/C running? And how was the ambient temp/humidity?

It was 80ish and humid and I was in the garage, engine facing away from the door. AC was off.
I tried to take a look again last night and it was much cooler, I couldn't get above 3 bars and the fan never came on.

I'd say its fine; just keep an eye on it if you ever see it getting that high again. I'm assuming you have the stock radiator and fans? You could get yourself a lower temp fan switch if you're overly worried about it, but that'll cause you to lose some coolant in the process when you make the change so you'll want to go through the bleed process to get any air out again.
Here's how I personally diagnose each bar on the AP1 ECT temp gauge:
1 - Cold (always on)
2 - OK to VTEC
3 - Normal
4 - Warm
5 - Hot/Warning
6 - Danger/Shut er down
7 - Big Trouble
I have a sticky note with this written on it (along with the temp ranges for each) on the inside of my radio door.

I have an AP1, just installed the ECT from Modifry. Based on his chart I am constantly over 190, just idling in my garage. The fan seems to kick on at over 205, because I bump to 5 bars briefly then back down to 4 at the end of the cycle. This to me seems hot for just sitting in the garage. Also I would have expected the fan to kick on sooner. Any thoughts??
I have a BT ODB2 transmitter to my android phone that gets my coolant temp data. I run 176-186 mostly (WHEN DRIVING). When I'm idling at a stop light even on a cool day it will get up to 196 or so. Dead heat of the summer it will bump up to 205 to 210 but the fan kicks on and then it drops.
I really see no issue here.

Yeah, I have driven the past 2 days and haven't seen more than 3 bars.
I am still a bit concerned that the dang fan doesn't come on until 5 bars, but the ulternative (173) seems too low IMO.

on the website
usually 205 is the optimum running temp for most cars, from an emmissions standpoint. 220 is a bit high, but sitting still isn't too concerning. 235 is definately concerned and shutdown time. engines will live higher, but i'd start looking for some water wetter or something. with an aftermarket ecu, can you change your fan kick on temp?
