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.

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 4 ай 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 4 ай 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.

@stratifiedauto 4 ай бұрын

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

love the comparisons, thx for sharing that info. Im keeping mine mild, but looking at intakes, torn between the more sealed up cold air intakes (MST V2) and then the more open ones such as the K&N offering. Currently have the Velossatech Big mouth with the snorkel to the flapper door on the stock airbox. Not sure I want to keep that portion as it looks constricting, may just run the big mouth intake portion and let the flapper door be free without a snorkel attached. cheers!

@JordieG8 5 ай бұрын

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 5 ай бұрын

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

@BrodeyDoverosx 5 ай 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 5 ай бұрын

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

@garagecedric 5 ай 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 4 ай 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.

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 5 ай 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.

@TerryManitoba Ай бұрын

You are currently doing an Ecutek tune on my GRC and I have a quick question. (just sent first - 3rd gear WOT) Should I consider a different map (Through Map Slot Switching) for daily home driving at 1k foot elevation and a 2nd map for more spirited higher elevation (5k plus) trips. Or does that even matter that much THX 👍

@stratifiedauto Ай бұрын

If it’s just the elevation change that is different and not the fuel then that is compensated for outside of the map slot maps. The map slots are a small number of tables for boost, timing and fueling designed to deal mostly with different fuel types such as ethanol and pump gas or if you like to have a more chill and a more spicy tune. If that is the case then yes we can do multiple maps.

@TerryManitoba Ай бұрын

@@stratifiedauto Good to know THX for the quick reply. Also, I sent this by email but thought I would ask here - as I did not getting a reply. "It may not matter but I wanted to mention that I have a iMT (rev match) dongle. This harness forces the iMT (upon starting) to remain where you had it on your last drive" does that effect the Ecutek tune? Cheers

@GRSuperSonicRed Ай бұрын

Also how much psi are you guys running? Have you guys experience any valve float?

@stratifiedauto Ай бұрын

We have experimented with up to 30psi but that’s a bit on the high side. On ethanol the car will be happy in the upper 20s tapering down a couple of psi in the top end. Without reducing back pressure you can push the top end a bit too much and induce some issues and misfires but with smart tuning you can avoid this.

@ZmbiBglz 4 ай бұрын

is this all on stock boost or did you juice up the boost a little? i didnt catch you mentioning boost levels at all

@stratifiedauto 4 ай бұрын

With tuning we do dial up the boost.

@banimanFJ 5 ай бұрын

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 5 ай 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

@banimanFJ 5 ай бұрын

@@stratifiedauto Got it, thank you!

@BrodeyDoverosx 5 ай 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 5 ай 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 5 ай 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.

How does the ecutek work with the drive modes? Like eco/norm/sport?

@stratifiedauto 5 күн бұрын

These modes are not affected. The only part that is in the ECU is the pedal mapping for these modes.

to run e30 would i have to add a flex fuel sensor?

Not necessary to have the sensor. We put a second map slot on the tune and you switch to the e30 tune when you have the mix in your tank using the cruise control buttons.
