GR Yaris The EcuTek thread

On revision 4 now with Litchfield. Updated metrics below:

Hi. Has anybody just done a ECUTEK tune in Australia (besides the Full Boost Yaris) without any further mods to the vehicle? Just looking to do the same to my car. I believe Full Boost ended up with 188wkw - which is more than enough for me. Thanks :)
 
When I got my ecutek tune done the car had only an aftermarket intercooler (for better heat management, not power) and a printed intake scoop. I got it tuned at the same place as Full Boost, they've done many GR Yaris and Corollas.

Since the dyno run I've since fitted a catback exhaust (Fujitsubo) and I couldn't be happier with the car's performance.

Before and after ecutek tune.

The car has an Airtec intercooler, turbo inlet elbow and printed intake snorkel, otherwise stock.

Really happy with the improvement. The additional low torque is useful on the road, but it's the top end gain I'm most looking forward to using next time at the track.

Hi. Thanks for the update. I’ve just got an MST v2 and Invidia Cat Back. Going to take the exhaust off next week and go back to stock due to early morning starts. I’d like Trent to tune it also, but I’m in Brisbane. Have to figure out the remote tuning will work. Warranty is up in Feb. cheers

Just ask around for local tuners, there are a few.

So that's interesting, the new graph has lower drivetrain losses than the stage 1 graph. Just goes to show you can't just scale up losses when you add power as - as a % - the new car has lower losses despite more engine power. See a lot of places just add a blanket 20% but that clearly can't be applied here.

I also had a quick chat with Matteo and he's said they've also seen approx 380bhp with similar hardware so it does look achievable which honestly has surprised me a bit, I thought these were maxed out around 350bhp going back to the early Syvecs days. I guess times really have moved on

Sorry to be the guy who keeps dragging up posts from years ago on the forum. I'm rapidly forming the opinion, only the WHP numbers actually matter for real world performance.

To make a statement - A stock mk1 GR Yaris makes 210 - 220 at the wheels in good air with good fuel on well known dynos at well known tuners. These losses are actually quite static if other variables stay the same. e.g. the car lost 50hp though the same wheels, tyres, gear oils and RPM mechanical friction. I strongly agree with comments around fixed % losses don't scale correctly as you tune the engine.

So when I see big engine hp claims based on adding a fixed % to the WHP measured, its a false conclusion that doesn't tell you how the car performs anymore.
 
Wrapped up the remote tuning with Litchfield now. 6 revisions in total. Should be able to get fresh data this weekend.
 
It would be very interesting to compare a remote mapping to one on the dyno and then one one the road. Litchfield did mine on the dyno first and it was ok but I was never amazed. It was one of those,” yep that’s better”. The later remap when they took the car out on the road for a few hours was a game changer. It was like “holy shit, where has that been hiding and a grin from ear to ear”
 
Yep. It looks like the one to go for. 5k or something, looks like a great product
 
New Lamspeed bolt-on turbo solution looks pretty handy matched with Ecutek.

I'll be keen to hear some user feedback regarding driveability for mixed street and track duty.

I would want to know the turbine specs, they look quite big! Seems to take a similar approach with similar power claims to GCG Japan's hybrid

Might be similar to the Ichiban unit? I guess most use the G25-660 unit.


They also quote 450hp but im not sure if its WHP or not.

Oh nice, more options coming to market! This one appears to be a new Garret G25-660 core unit (Artec uses the smaller 550) rather than IHI hybrid (As per Lamspeed and GCG). Looks to spool later but possibly flow more.

Since EcuTek is moving the game forward with (soon) possibility to do:
- remote tunes through app
- advanced app logging
- multimap (4) through app
- Launch Control with BOTL
- Port Injector Scaling
- Flat Foot Shift
- Rolling Launch (antilag)

I think it is time to create a dedicated thread to discuss all things related.

For UK, it seems to me Litchfield is a strong partner for this, since they write they helped in development. Fensport are a master tuner also. And not to forget Whifbitz that do some serious builds.
ACME in Italy seems involved too, they have been tuning the GR Yaris in the rally cup for years so they know their stuff too.

Would love to hear people with own experience and also sharing logs, so we can discuss settings and what to target depending on preferences, hardware installed, performance goals, power delivery preferences and reliability trade-offs.

Did you end up getting an Ecutek tune @Onehp?
