We got our own GRC! We love this platform, its performance and what it has to offer so we had to build our own to gain as much experience as possible with the GR Corolla / Yaris.
In this video we go over a few first mods when taking it to the track (oil change, exhaust heat wrap), baseline the car and then get into tuning. We use the latest EcuTek software with RaceROM V2 which allows us to have multiple map slots and improved boost and ignition timing control. That means we build tunes for both pump gas and ethanol on the same file - no more flashing to switch fuels!
Finally, we look at the potential power gains from adding on an intake with some creativity.
This is a good technical look at the car and I hope you enjoy it as much as we did and follow us on the rest of the journey with the GRC!

Great job! Keep them coming, enjoying the thoroughness and dedication to this platform

I just ordered my Ecutek and cannot wait to see how this car performs after tuned. I came from the STI platform and honestly I feel this is a way more playful platform. I do miss the STI but I feel this is a wonderful replacement! What a fun little car

It is. Tuned and if you have with some e85 it’s so lively and fun. Let me know if we can help you out with the tuning.

this was great!! just ordered my sxth intake need tune next cant wait to see more videos!!! put them out asap haha

We have a lot more coming. An intake is great to open up the top end. Tuning ties it all together :).

Hello. Awesome testing. Speaking of optimizing the tune on e85 what exactly does it entail? I noticed during tuning that we need less timing before 3.5k rpms to be happy. 😊

@stratifiedauto 11 күн бұрын

Optimizing the tune for ethanol is setting up appropriate fueling, timing and boost levels for the fuel used. Are you tuning your GR?

@BulliKid 11 күн бұрын

@@stratifiedauto I’m tuning a different platform. Changed from 93 Oct and low boost to Full E85 and same boost level. I adjusted the 30%+ fuel difference and increased timing slightly on the entire map. But then had to reduce in the low rpms due to researching the burn rate of e85 and low rpms. Just curious if you saw that during your tuning with timing.

Generally not the case. I would do your testing on a dyno with appropriate instrumentation.

I may misunderstand the configuration - does wrapping the rear sensor in fire sleeve end up giving a potential false negative read because the sleeve is blocking accurate readings? Or is the sensor itself already internal/covered and not exposed, the sleeve just protects the exhaust-facing-sensor housing from getting hot, which throws the false positive if it is not covered?

@stratifiedauto 21 күн бұрын

The sensor is internal. I am just wrapping the external body of the sensor that is exposed to external radiant heat from the exhaust

@BrodeyDoverosx 21 күн бұрын

In most ECUs there are heatsoak algorithms applied, so you might be right. There is cooldown hysterisis that is modeled and the sensor gets an offset applied to it.

@banimanFJ 21 күн бұрын

@@BrodeyDoverosx Right. And I am trying to figure out if the fire sleeve is mitigating false positives or actually inviting false negatives, thereby not allowing the diff to know it is legitimately overheating and then ends up shattering because the sensor was numbed/dulled due to the fire sleeve being present.

@stratifiedauto 20 күн бұрын

The thermal issue is not the actual differential. It is the clutch pack that always slips to some degree since the rear end is spinning a bit faster than the front. So it’s a clutch pack longevity issue rather than a differential issue. It’s also tied into oil maintenance intervals. I recommend changing the fluid more often when racing or doing lots of track work.

Thoughts on obtain booster to help with knock in states they only have 91 or even ethanol booster.

@stratifiedauto 15 күн бұрын

Yup octane booster works!

@brandon9491 20 күн бұрын

So, putting a little ethanol in the tank with a stock tune will help the top end?

@stratifiedauto 19 күн бұрын

It depends on how good your pump gas is but it definitely won’t hurt. Especially in hot weather or on track.

@happyhills_garage 14 күн бұрын

Awesome coverage of the capabilities of the GR in this video! I'm sure you're testing all sorts of configurations right now, or will be when you get the time to, but what are your thoughts on possible gains/feasibility of a full bolt-on pump gas tune? Asking for a friend who may want to go into the Street Touring class with the SCCA. 👀

@stratifiedauto 14 күн бұрын

We will be covering what the modifications add as we add them. So far we covered the intake, fuel octane (ethanol) and of course the most important bit - tuning.

what is total cost and can I use stock car gr corolla circuit thanks

@stratifiedauto 20 күн бұрын

For the tune absolutely. Our car is stock hardware wise. Here is the link. www.stratifiedauto.com/index.php?main_page=product_info&cPath=358&products_id=1160

It’s nice being able to see the pressure ratio of the turbo. Give us all the sensors!!! I would be interested to know the reason behind managing the pressure drop post filter, perhaps it’s used to keep a reasonable depression for the PCV system.

@stratifiedauto 21 күн бұрын

The tune has pressure ratio limits that are closely monitored and this is a big part of it.

@BrodeyDoverosx 21 күн бұрын

I suspect it’s from a compressor longevity thing. My Abarth’s ecu models this stuff and after I raised the limits and with racing…my turbine housing cracked in 3 places, and wore out the bushings which caused the turbo to push oil. My new turbo has fixed a lot of unclear problems. So that melted turbo was too tired to push anymore and it really hurt performance. Btw, the blades were perfect.

@stratifiedauto 20 күн бұрын

Turbine housing cracking and exhaust heat sounds like a thermal or exhaust back pressure issue.

@garagecedric 17 күн бұрын

It can be very useful for modeling turbo speed and compressor outlet temperature for example,so the engine can derate if anything is going over the limit.

@michelhadid 2 сағат бұрын

Yes. And keeps a constant eye on the actual pressure ratio, instead of relying on a model with a lookup table. If your filter gets clogged or has a hole in it, you will still be running the turbo at the same pressure ratio. Specially with a variable airbox like this one where the pressure drop across the intake system wont be the same with the flap open/closed. Probably not worth it for an OEM cost-wise for most applications compared to a modern ECU where everything like that its modelled, but very nice, specially when tuning them.

Is it reasonable to expect that a completely stock tune car could pick up power running some ethanol in the tank?

@stratifiedauto 13 күн бұрын

Yes the stock tune even has some room. But of course not as much as with running a tune made for it n

Ran mine hard for 5 - 20 min HPDE2 sessions at Sonoma last month 80 degree day. No heat shield and had no over heating issues. Car ran great and consistent all day. Tires and brakes took a beating. Can’t wait to get back out there. This car is more capable than my previous 19 STI.
