Tuning the World's Fastest Hatchback

[@denstoj]

Tuning the GR Yaris? Sure. But let’s talk about how Ben’s Crocs were dialled in. 😎

[@morganazzopardi2187]

Good job. Very good explanation

[@denstoj]

Cheers! 🍻

[@Plantandequipment]

Does ecu tek have adaptive learnig or preset for existing and new hardware add ons

[@denstoj]

What kind of hardware add-ons are you thinking?

[@HanksDeuce]

At the beginning of the video, are you confusing horsepower and kilowatts? 195 kw = 261 hp. 267 kw = 358 hp.

[@denstoj]

Yep, jumping between the two. I think in kw but hp gets more attention with the US audience 👌

[@denstoj]

To clarify, it is 195 hp and 267 hp but it's at the wheels 🛞 😎 hence the confusion.

holy sunburnt legs

[@denstoj]

Next time, Daniel needs to wear pants?

[@boiipauly]

You lose adaptive cruise control with an aftermarket ecu? Thats my favorite feature 😭

[@denstoj]

Yeah exactly the troubles with trying to balance an ECU setup for both street-ability and track use. Trade offs🤔🤷‍♂️

Another Belter of a Video. '' Gr #427 Rallye here.. 😁

Cheers legend. I'm not sure what @DarrylSmith-r3p's Rallye # is?

I'm pretty much running this mod list from this build with the GCG turbo on order. You said factory fuelling is maxed out but they didn't go bigger port injectors? if you were tuning this again would you have preferred them swapped?

[@denstoj]

I’m not exactly sure how much of an increase in injector size ECUTEK can handle or how much of a difference it would effectively make considering the fuel control limitations on ECUTEK-a great question for Ben. 🤔 From a tuning perspective alone, I know he would have preferred an aftermarket ECU and upgraded injectors to fully maximize the GCG turbo and Kelford Type-A cams….but that can lead to a slippery slope with more mods. What are your goals for the setup, and how do you plan to use the car?

[@jaxomliam]

​@@denstoj your customer story aligns exactly with mine, and I have everything in this setup except I'm using the EZP instead of A kelford cams - the motec @ 8k AUD is just a difficult boundary to cross in terms of $$ to value ratio. My goal was to make 250 peak without losing too much on the curve, but we'll see if that's possible. I know my tuners been struggling to get me above 26 psi 193kw rolling dyno on OEM turbo, we'll see what the GCG can do; it's possible ecutek needs a bit more time in the market but I think this build setup could be a decent compromise for a lot of people. Thanks for sharing this series though - I think it captures a sweet spot a few people will want to replicate.

[@denstoj]

@@jaxomliam Ah sweet. The $ jump to a Motec is a tough boundary to cross. 250 kW is definitely ambitious, but with the GCG turbo, it should be achievable without sacrificing too much of the curve, just not sure if you'll have to swap out the EZ to the Type-A. A good question for Kelford. The limit you’re hitting with the OEM turbo is a pretty common challenge, and yeah with more time in the market this setup will get better with further ECUTEK development. Glad you're enjoying the series. Like you said, it'll a be a common setup for people looking to push their GR Yaris without going all-out on a standalone ECU. I'll let Ben know about your port injector swap question. Hope you're enjoying your long weekend. ☀

[@Benchmark413]

Yes the swap to larger port injectors would be nice, however I personally feel as a calibrator there isn't all the tools we need available *YET* to correctly dial the larger port injectors in to OEM standards. That's where the jump to Motec or Syvecs for the ecu will have its benefits at this stage.

[@Kelford-Cams]

⁠@@denstojthese guys can achieve the power on the EZ, they may need a little bit more boost but the power figure is set from the turbo not the cams. The cams only support the power, at 250kw the EZ cams are only just starting to work and would sacrifice bottom end power going to the A spec

[@garethherman4074]

So what was the end result power wise??

[@denstoj]

Check out the graph at 4:54 👍

[@garethherman4074]

@denstoj 👍

[@garethherman4074]

@@denstoj so roughly 40hp gain from cams, turbo, intake?

[@denstoj]

@@garethherman4074 yes, at the wheels with the limitations as mentioned in the video (fuel and ECUTEK)

[@hksgrc]

HELL YEA ❤

[@khamid1]

@denstoj have the port injectors been upgraded?

[@denstoj]

Stock injectors all round.

[@woznaldo]

Good information but, not sure how much I can trust a man in Crocs?…. 😂

[@denstoj]

They’re not just any Crocs - they come with extra ponies, courtesy of Ben’s daughters.

[@Happydays-w3z]

Those numbers don’t make sense when the car is only hooked up to the rear. Do a proper video and test it as it’s supposed to be and that’s in AWD

[@khamid1]

It's been rolled off the dyno rollers halfway for the chat in the video.

[@denstoj]

The GRY actually has a "2WD dyno mode" which cuts drive to the rear wheels and turns off safety features such as active traction control and ABS. This eliminates AWD drivetrain losses. Regardless, what’s most important is consistency across the tunes to gives us reliable results to compare rather than dyno-to-dyno as calibrations can vary.

[@markb7000]

Don’t these engines have wrong ring gaps from factory. Dangerous to tune these fragile motors IMO

[@jaxomliam]

Stop listening to that guy from Italy.

[@khamid1]

There is quite a bit of misinformation going around unfortunately
