He doesn't have an EQT tune.

Crazy differences in 0w20 and 5w40 I’ve noticed post 24fx ecu update
- Thread starter Keehs360
- Start date
Good guess, too bad there’s no change log for the 24fx
Shhhh I can have whatever he wants. $20 is $20
You clearly missed my point. Would it help you get past the 2nd word, if I removed EQT and instead wrote "tuning companies" or will you still get stuck on he's not tuned then?

The changes re: coolant temps have nothing to do with EQT themselves, it was an update to tables from Cobb. Any tuner/platform with access to the same tables would be able to achieve the same improvement. Pretty sure UM has had them for some time now.
Point is this post is silly, unless the cars have identical ECUs, plugs, mileage, etc. 5w40 is plenty viscous at normal driving temps, and is totally fine for cold weather too unless you live in the truly cold north.
jim wasnt trying to be a dick, i am sure he didnt realize the possibility of the targets being moved some and it carrying over to other 3rd party tunes in their base files.
i dont think its silly due to the complete opposite being true. the car with the crappier oil is tuned but oil temps are lower. and its only 2k miles less than the car with the 5w40. the car with the 5w40 is mechanically the same and had lower oil temps before the update then higher after the update.
For normal street driving that sounds expected, the tuned car likely has lower coolant targets to mitigate the sort of driving expected from it.
How are you measuring temps anyway? The in-car gauges are completely made up numbers that seem to be fairly loosely related to actual temps.

Good question. Going off of the in car gauges. Iirc it’s a bullshit number that’s a result of some weird formula dragged from other temps
I can start logging a more precise parameter if you know the name of the parameter I should be looking at
Which was the sole reason I brought up EQT. I know for a fact they've altered these in their tunes and I've seen significant drops in my operational oil temps from daily driving to track events due to these changes.
Unfortunately, and a common theme on the internet in general, is people are so eager to find errors posted by other people, they ignore the rest of what's posted when they think they've found one. I think we all succumb to this to some degree. I agree I don't think jim was trying to be a dick, but annoyingly in this case he couldn't get past the 2nd word in my post before he had to try to point out how I was wrong.
I think I made it pretty clear my conjecture has nothing to do with EQT, but a possible change in coolant targets for shorter cold starts (my guess is for the potential lower emissions). But, we're getting too off topic. Carry on.
I also had no idea eqt did that. I read that apr redid their tunes after measuring cylinder pressures and cylinder temps or some such. I also read as soon as apr did that just about every other tuner followed suit. I've no idea if any of that is true. I also can't recall what prompted apr to measure cylinder pressures and temps.
Is that scenario what you're describing
Note that this is for GTIs only, 2019 R's are still on VW 502/504.
Correct, GTIs.
When I inquired about their base being upgraded to s0007 post 24fx dude told me “make sure you’re on the 0w20!!!!!” Like dude sounded super serious about it
interesting thing to note. Apr is practically demanding you’re on 0w20 while eqt seems to be ok with u on 5w40
