I have noticed this as well.

I had problems with the v4 e85 tune. After the ambient temp got down to 50F or so my car wouldn't start for shit when the engine was cold. Anyone else have similar?

Yep it is a common issue, do some searching as you need to modify some cranking tables. Link to one post below;

Hello folks,

I got my 2018 BRZ Sport-tech RS a little more than a month ago, I have about 1500km on it.

I got the OFT V2 and the FT86 UEL Catted Header. I have access to Petro-Canada 94 octane fuel here.

(Also have the Perrin intake, sound tube delete and Invidia N2 catback)

I just downloaded the ZA1JN10C Stage 2 4.03 file to my OFT after loading my stock ROM into it.

So after reading a few comments in this post I have three questions:

1 - I live in Montréal, will this tune cause me issue during winter time? My car sit outside but I have a block heater that I can plug.

2 - There seem to be some inconsistencies between version 3 vs 4, etc... In your experience, is version 4.03 good?

3 - My car is brand new, I need it to last at least 5 years +... Is this likely to negatively impact my car reliability in the long term? (this might be a stupid question but I'm a car noob)

Thank you

lower power mods are not likely to adversely affect reliability.

They can affect your ability to warranty things in the event that a problem arises.

Ok cool thank you for the quick answer there.

I'm not worried about warranty, I have stored all my OEM parts and I have access to a dealer that is willing to close their eyes when I go through one of my contact.

Anyway in case anything REALLY bad happen, worst case scenario I take the money out of my pocket but unless there is know reliability issues with the stage 1 or 2 tune, I'm not worried.

Based on the binge reading I've done, I don't really think you will have issues.

I would recommend an oil cooler though as it seems oil gets hot in these cars at stock, getting rid of the OEM header with heat would likely exacerbate this.

I have purchased the ceramic coated header and I also have some heat barrier adhesive for the oil pan just in case.

What oil cooler would you recommend? Any DIY OEM cooler? Otherwise I'll have it installed at the same time as the header.

Do you know if the oil cooler will cause issue in winter here in Montréal? 0 to -30 celsius temperature sometimes.

I can't personally recommend any as I just picked up my 86 last week. I'd suggest reading some more but I'm currently looking at the one from MAP.

The cooler has a thermostat so the valve only opens at a certain temperature, so the winter will not cause an issue.

As you live in very cold climate a good option for road use could be the OEM type water to oil cooler, this will heat also your oil the coolest days:

If you live in a cold climate and only street your car the OEM Forester warmer/cooler is what your after.

I have the Forester oil to water, it helps get the temps up, and, living in Australia with temps up to 40°c, I haven't had any issued with my oil temp control, albeit it is still NA and spends most of its time being beaten on the street.

As for oil to air coolers, I had to block the heat exchanger on my 15 STI during winter as, even with a thermostat, it had issues getting the oil up to temp and keeping it around 100°c.

The oil cooler/thermostat were Mishimoto, 90°c job, 19 core IIRC.

I'm reading mixed review on the OEM warmer/cooler. Many people say it's useless if you only street your car... but then if I'm OFT Stage 2... I want to be safe...

It's an expensive kit to buy if it's not really needed.

I have the block heater installed and I plug the car when it goes around -10 celsius.... (like this morning).

From what I’ve seen/read it seems to warm the oil up about 10-15% quicker. And keep the temps down about 10 degrees Fahrenheit in hard driving. As well as cool it back down much quicker on “cooldown” runs.

Seems to be the perfect solution for NA DD/spirited/canyon driving non track setups.

I have also a MY18 BRZ but EUDM version and I am going to fit the NED factory type water to oil coler.
If you read in a thread I posted before, our cars when stationary and rev at 3000rpms tend to have elevated engine coolant temperatures, probably for emissions control, close to 100C degrees (and back to 93C although on road no more than 92-93C) thus I'll fit also a slightly lower temperature thermostat (6C lower than factory which opens between 88-95C degrees) along with the cooler to counter balance the small coolant temperature increasefrom the factory oil cooler.
But in your climate conditions I don't think you need lower temp thermostat.
The factory type oil cooler, at least the one from NED, it's not expensive I could say is the cheapest oil cooler for this car!
