Thank you!

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.

Thanks, enjoyed the video. Will definitely be reaching out when I mod my GR

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. 😊

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

@@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 know right … tolerances are just getting tighter.

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. 👀

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.

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

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

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

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

@garagecedric

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.

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

@stratifiedauto

Yup octane booster works!

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

15 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

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

​@@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.

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.

the dyno numbers are done with the intake top part open? what is the number with it closed like oem?

@stratifiedauto

13 күн бұрын

We show that in the video.

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

@stratifiedauto

14 күн бұрын

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

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

@stratifiedauto

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

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

Of course the clutch pack isn't overheating it with only 3 hot laps
