    GR Yaris (Gen 2) Mobil 1™ ESP X2 0W-20

    Doesn't really matter if the oil is good or not. I wouldn't risk putting anything without the specific required specification on it. If something were to happen to your engine, and Toyota finds out it was oil lacking the correct spec, they will have an easy reason to void your warranty. There...

    GR Yaris (Gen 2) Mobil 1™ ESP X2 0W-20

    No, should be using oil with API SP specification, and this one doesn't seem to have that.

    GR Yaris What did you do to your GR Yaris today?

    Like some others have mentioned here, I have struggled with a bit of a rough idle lately. Got CRC maf sensor cleaner and sprayed it down about a week ago, and it seems to have solved it.

    GR Yaris What did you do to your GR Yaris today?

    I continued my yearly tradition. Put summer wheels on last week, started snowing again yesterday. Pretty sure that's 3 years in a row! :LOL:

    GR Yaris HJS exhaust / catback noise question (daily and motorway)

    I'm going on a 4000km road trip this summer with HJS cat and non-resonated Milltek 🤷‍♂️:LOL:

    GR Yaris Winter Wheels and Insurance

    Haha, this seems so odd to me... Here your insurance would be void if you didn't have winter tires on this time of year, and police would also give you a fine.

    GR Yaris What did you do to your GR Yaris today?

    I've been through a few different ones, a DNA purple one that broke, then back to stock, then to powerflex black and now on the Collins one, and I noticed a difference between each one. Powerflex was a big improvement over stock for me. The Collins one feels pretty similar, but less NVH.

    GR Yaris The EcuTek thread

    I have not had it dynoed, as this is done with remote tuning, but Litchfield estimated around 330 with my mods. I don't know how accurate that is, so take it with a grain of salt. My power mods: Airtec intercooler MST intake HJS Sports cat Milltek unresonated GPF-back exhaust

    GR Yaris Front Bumper "Lip" - hairline cracks in paint?

    You sure you don't have PPF on the front? Pretty poor install in that case, but looks a bit like the edges of the film

    GR Yaris The EcuTek thread

    I don't know if there are still some torque limitations, but I definitely have more torque. The logs say 400-410nm, no idea how accurate that is, but the butt dyno is impressed. I wouldn't want any more in the name of mechanical sympathy 😅. It pulls a lot harder than it did with the tuning...

    GR Yaris The EcuTek thread

    I pulled the trigger on Litchfield remote tuning, and currently on the 3rd revision. The first base map felt slightly unrefined, but the revisions after have been amazing. Got the map order switched, so it starts up in stock tune. Apparently a future version of ECUTEK software will allow the...
