Your videos are so informative. Have to be the best videos on the net about the Yaris.
So, the next mod should clearly be a water injection kit to help cool the intake charge and keep it in the sweet spot of 30-40 degrees.
or just a better intercooler
OEMs will usually add torque limits to various gears, pretty common. You should be able to log SAE engine load and final spark OBD PIDs on the dyno. This will give you the best indication if the ECM is reducing load in various gears. Maybe the boost control isn't fully adapted with the lower delta P across the turbine so the proportional in the boost controller is over-correcting at higher mass flows. Pretty common for this stuff to happen with aftermarket mods as we never test it with low cell count metal matrix cats.
My Forte GT does this, I use a JB4 though to get around it to great effect especially with ethanol.
do you work for an OEM? I was under the impression that toyota petrol boost control is open loop not closed loop but i could be wrong.
@@OFFTAPnz yes I work on pre production OEM calibration for a German manufacturer. Toyota use either Hitachi or Denso controls and the boost control is based on turbo turbine power pre control with a slight proportional derivative control. Most OEs will have boost control that is modelled which is multiply levels more complicated that aftermarket ECUs.
@@dj4monie I don't understand what you are trying to say, sorry..
@@AndrewEG ah ok yeah that makes sense cheers for the info mate
Very informative video as always Andrew, love your work.
Also sounds like a little Nissan VQ engine
Nice touch with the trombone in the dyno scenes !
I can totally see why Toyota chose the smaller IC, for regular use and the occasional amateur track day/ twisty roads, it's good for response with smaller diameter pipes and IC.
plus the car heats up quicker for emissions, it's probably one of few ways for a car like this to exist in today's market. the good part is we can change it :D
Keep them coming mate. Love the GR series
Id like to see how an intercooler and wmi changes the car. Love the series
Me too its really really restricted apparently
I want a Yaris GR bad. Looks like a blast to drive. Jealous of the countries that get this gem
Thanks for showing us everything along the way! people should understand everything at this stage is just testing will take some time to figure it all out and put together
I wish we got these. I can totally make an exhaust that doesnt blat like that.
so can we, and others, but we didn't with this combo
I hope that a new airbox can make it somewhat more consistent. Watching Evolve's video on it explains the wildly different dyno runs
Can't wait to see what an intercooler does. Too bad we won't get these here in the US
You boys are always getting shafted huh :(
@@BNR_248 wouldn’t say shafted. I’d love the choice of v8 powered cars and utes they have.
You are getting the hyundai veloster I would have loved one of them
I think I saw it was in track mode, but I think JCR mentioned he was flipping the mode between launch and one of the changes to get the best out of the 1/4 - going with the cusco LSD?
that dump pipe sounds horrible down low. you planning on fixing that up?
i do like how in depth your doing the dyno runs tho *thumbs up
Good luck keeping intake temps below 50°c in the Adelaide Summer😂.
adelaide is a hole anyway lmao
@@camver100 enjoy living 50km from the city in your 3 bedroom home on a tight budget lmao
Looking forward to when someone cracks the ECU of that thing. To see what it does and why. My GR also does some weird things, boost is all over the place and after refueling it takes some time to recalculate the new octane level or something like that. It doesn't like boost the first km afterwards. Hasn't been above 5°c here in Norway yet, so havn't experienced AT issues, but interesting tests.
Yeah, I can't wait to tune my yaris. I am a tuner and have an N54 which I modify the tune for almost every week really, so it feels a bit limiting to not even be able to datalog some decent data, that's why I am considering an aftermarket ecu.
Unfortunately it's highly unlikely to be cracked.
Ebay power chip would add 50bhp
@@sodazman what is the reason for that?
Can't wait for the project supercar R32 update videos...
💯 This yaris is for people that identify as gender neutral..
Thanks for an honest video on the yaris, would be interesting on how quick it is around Eastern Creek
Hopefully we find that out soon too
13 flat. Not bad. Thanks for the 1/4 runs. Was good to watch n see you improve a bit on the 3 runs. Interesting with the dyno runs. Be sick to see once people start seeing how much a stock block can take (circuit or track) 👍
Being a factory turbo car I would think double the horsepower isn't out of the question. People whine too much about lag though. Garrett G25-550 is a natural fit. From the testing I've seen you would only lose about 500rpm. My Forte GT sees max boost by 2500 rpm and it makes power almost to fuel cut peak power is 5878 rpm on my dyno runs fuel cut is 6700.
@@dj4monie 2500rpm wouldn't be to bad in a 6 spd circuit car. Who knows how they'll take the mods 😁
So basically it’s fast as long as you don’t need 4th 5th or 6th gear when it’s hot!! glad mines not delivered until July...
in Britain were already getting cars with heat soak in the transmission causing lights on the dash and power loss after 20 mins on track .... at 7 degrees Celsius 🥶
Cheat code
1. Hand brake on engine off( starting point)
2. Engine on
3. Hand brake off

Display will show AWD test mode and car will basically be free from safety and limitations and gain 5hp or so on dyno
Interesting stuff for a soon to be GR Yaris owner
I love this channel 😍
3rd gear dyno runs. Are we in America hahaha
Sucks but was only way to get clean run. At least we acknowledge and explain why
Any reason you didnt take the rear seats out also? For the track it would help quite a bit. Theres probably another 20-30kg there. My fiesta st rear seats are 30kg😬
I think they spoke abour being able to put it back to ”road-spec” in a short amount of time. Guess taking the rear seats out is a pain in the ass.
You should check the comments from the previous video. He explains it in more detail there.
Big ass front mount, a Haltech ECU next, then just send it?
I haven't seen an orange track pack Yaris before. They come with an Lsd from memory.
1. It's wrapped (as per video)
2. Australia doesnt get track pack
@@MotiveVideo I take it its the Rallye then?
@@Gooie69 nope. The rallye Haven’t landed in Australia yet.
@@geokon7192 you sure? I'm certain Andrew has mentioned it's a Rallye with the Lsd's numerous times.
@@Gooie69 pretty sure he mentions its none of those things numerous times. Even in this ep.
First things first, was that 195kw at the wheels and if so that’s pretty impressive. I’m having my exhaust fitted this week from turbo back by Maxx performance and I’ve asked them to dyno run the car but now watching your video I’m a little tentative as I’m also running a play box running through 3 sensors that supposedly brings it’s up to 220kw at the fly wheel. Is there an bigger intercooler for it yet?
We and PWR are working on bigger intercooler and pipes
@@MotiveVideo that’s fantastic. How long before it will it hit the market?
Really needs a driver mod.
lol. ok
So happy you use kW instead og hp bhp, etc. Its 2021, kW has been the officiel unit for a long time now, hp is dead.
That panel filter is not the problem, that std intake is terrible.
This GR Yaris is like a Daithatsu Charade GTti on steroids, like it
I still like hose pressure. It's not a toaster oven...
according to Litchfield this car needs a proper cold air intake system,
now I'm sure Toyota knows this, but I suspect they deliberately designed this car to heatsoak and drop a couple degrees of timing and some boost to make less power than they said it does to make the motor last longer, it is the most powerful 3cyl on earth, its the most powerful 1.6 available, I wouldn't be surprised if there is some electronic sandbagging in favour of warranty going on.
It would be the most powerful 3 cyl on earth. That's because no other car manufacturer want to create such a boring lifeless engine.
@@ashcosmo3854 VW. Ford. And BMW definitely make turbocharged relitivly high performance 3cyl motors.
@@nedyahyakcam and how are the sale figures? No one wants them
@@ashcosmo3854 the fiesta St is really popular. The 1.0 EcoBoost is everywhere. And every new polo apart from a GTI is a turbo 3.
Take your blinders off. Maybe you will see more
@@nedyahyakcam Hold up. You said performance cars. No performance car enthusiast owns any of those cars lmfao please.. anyone who gives a shit about cars don't own those vehicles.
Can't say we've had such inconsistent results doing dyno runs back to back. Doing the cat back definitely netted a consistent increase in power too....
Buuuuuut it's a lot cooler in the UK and maybe the dyno we're using has better airflow?
Either way, enjoying the videos dude 👌
cold weather conditions would change everything
@@MotiveVideo indeed it would.
There are instances of cars pulling power in stock form over here though and throwing a "Reduced Engine Power" message - despite the cold weather. So it may be that Toyota drop an update to reduce the sensitivity to help reduce some of maybe over zealous safety parameters, or we just have to be patient for a proper ECU remap option 😅
@@SubaruVideosUK cold weather will push up the power due to increased air density so the ecu will pull more out for torque management.
@@SubaruVideosUK Australian cars had some sort of software update to fix that. We started getting deliveries in October and into December folk were getting those faults so Toyota patched existing cars and all which come in to Australia now have that software. I don't know if it was a worldwide update. I would guess you'll start seeing cars in southern Europe start getting that temp error on the road in slightly enthusiastic driving scenarios as the weather gets warmer.
Ep 4? The last episode says ep 2. That's ep 3.
The filter and exhaust have not surprisingly created no real gains.
The 4th and 5th gear dyno runs would appear to be MAT related issues. It would've helped having a 4th gear comparison graph on the 22 deg C day.
I would put a fogger on the intercooler. I think it would beat all the other upgrades combined at a fraction of the price.
As for the runs at the drags... Unless you can launch the car effectively it's pointless. That will involve less aggressive launch with the ability to balance clutch slip
So you are fitting a Cusco LSD? Which one you're looking to fit? 1/1,5 way Front or rear? Or both?? Subscribed
Hope Link come up with a plug play ECU
zircotec ceramic coat the hotside of the turbo, intake and exhaust manifold and exhaust pipework? i did on my evo.
Those emergency braking lights protocol (hazards) is annoying at the track
very
Even more annoying on the street, ffs😑
AHH is that what it is? I was wondering if it was some safety thing.
You reckon you would see better results with a cold air intake rather than the stock airbox?
Scanned the comments but didn't see it mentioned but did you have dyno mode on for the fourth gear pulls? For the uninitiated it's actually got a handy dyno mods accessed by a sequence that assures the car it's actually on a dyno sequence to select it is long but there's a few Vida around snowing how to select it
Yes, it made no difference
A bigger intercooler and some stiffer mount will make it into high 12
Wonder did u guys dyno at Test mode
And logging the boost
yes and yes
Where's ep3? Anyway well done guys
Am I right in thinking that the cooler air temps when you returned to the Dyno, didn't help you do clean runs in 4th or 5th gear?
5th it wont do them hot or cold, stock or modified
cooler weather made more power and caused more issues in 4th, yes
@@MotiveVideo interesting to know.
maybe toyota cheaped out on the high gears and knows this so power being cut to save them.
Every run it sounds like it's farting into a tin can🤣
At least there's no DSG queefs
Seems like the exhaust is resonating. It's a headache to have such exhaust on a car (I've been there)
Could it be traction or stability control kicking in as they may measure a slight speed difference between the front and rear wheels, if the transfer case is hydraulic like the GTRs and the delay of transfer engagement?
It's not that
nice
I'd like to see you getting more views as your videos are great. But I think your thumbnails with a 4 picture split are just too busy and very easy to skip past.
Was there any difference between the torque split modes? 13 flat at almost 108 is pretty good for something with no tune and 3 cylinders!
Tried sport and track mode. no difference
@@MotiveVideo also being a manual that time is all the more impressive. Dct or auto would surely be into the 12s!
What tires have you got on it, still the track setup from the video? I had Cup2's on my car that same night (silver wagon) and had a chat with my tuner who said that's why my 60ft was rubbish, I had circuit tires on it.
We had the Zestino 07RS on the lightweight wheels. On the heavier wheels it bogged and needed lots of revs, clearly the light wheels spin much easier
@@MotiveVideo Maybe a different tire on the nice light wheel? People seem to like the R888 on exotics (brookes from drag times & underground racing for example), I'm starting to wonder if I chuck a set on what difference it'll make. It's all so very interesting! I had my launch lowered and some more power added so I'll be back soon
Triple 8's are circuit tires. Brooks uses them because he doesn't want to risk dead hooking with drag radials. Not sure what's under the Yaris but with Haldex cars like the Golf R the front and rear like different things. Most of the really fast guys run slicks up front and stock rear tires or drag radials in the back. Actually he should work on slipping the clutch with a few of the devices available. They work great only downside is more clutch wear but excellent short times and no drive line damage.
Sounds like you need FMIC water sprays per JDM spec
Better intercooler kit and water meth will work better
@@MotiveVideo are u gonna get a haltech for it
Yeah, WMI is great, but how are you going to get the ecu to add timing/remove fuel when you spray? I needed 2degree extra timing to get it to match non injected acceleration, and ended up adding 4 degrees, and also 8% less fuel. So unless you can control ecu, WMI may not be the best solution.
Hype
Picking up my GR Rallye edition (track pack) at the end of this month here in Melbourne, would love to see if the front and rear lsd will make a big difference on the 1/4 time.
Ekanoo proved it does
Your car like most modern turbo cars have severe torque limiting. It will return back to stock torque levels in a few miles/km. My 2020 Forte GT which is also available in Australia picked up 10whp with 20% ethanol mixed with 91 octane we have in California on the stock tune. I added a Burger Motorsports JB4 on Map 1 in 4th gear made 217whp on 91, 234whp with a blend of 91 and something I'm keeping under my hat. Only tested to Map 4 = 251whp. It has the ability to run 12's in the 1/4 mile. It's done 9.2@78.5 on Map 1 with 91 octane. Only second time at the strip, no weight out of it. I can get into the 13's on 91. I don't care about circuit racing/hot lapping. We can compare FWD 1.6L 4 cyl vs 3 cyl AWD.
It sounds like a wet fart with the dump pipe and cat back
Tumeric Yaris.
Were you doing the dyno runs with AWD Test Mode enabled?
Yes, and it made no difference
Think you need to talk to PWR for a prototype intercooler
He needs water methanol injection, much more effective. I don't why everybody wants to be a parts changer. The car has an intercooler, make it work better. Replacing it does nothing when ambient temps go way up in the summertime. It's only slightly better than stock at that point. He can pick up a full second without changing anything even if he already has. That is what I'm out to prove with my Forte GT.
@@dj4monie There is even a nice little hole next to the battery where the tank would fit nicely :-)
Plazmaman
Time for some MTs ?😝
How many kms does the car have on it ?
2500
do u use track or sport mode at the drags?
tried both. no real difference
@@MotiveVideo :(
Are these Wheel KW or corrected?
always wheel
corrected is misleading
Are you doing any tuning?
we will be, yes
This needs a screamer pipe
Nope
Airflow? Where is the Airflow on the Dyno?
um, the dyno fan
@@MotiveVideo Seriously - the Hair Dryer Box in Front? 😂 May that worked if you put 4 of those in front of t he GR and run it full Power. Believe me, i was a few Days ago on a Dyno with can deliver 50.000m3 Air.
What's up guys lol
Tune it with E85
Cant
Put a glide in it 😂
A haltech will fix those dyno problems ;)
Can they dont direct injection ? I think only LinkEcu can?
All noise and no go
Where's the Supra yo?
Being used as a daily driver while Yaris is developed
@@MotiveVideo Nice, it's a shame we don't get the GR Yaris in the States, but we get the Supra
To me it seems like doing a catted down pipe is a waste. If you're going to run a cat than leave the stock.
it made more power and revs harder
@@MotiveVideo yeah just seems like we have to really work for extra power and there's some good power there plus, less heat, easier time on the turbo, better noise, lower price.
We think its a "must do" just based on noise, revs and driving feel alone
Any downpipe on the stock turbo is a waste on modern turbo cars the most you'll get is 10-15. You would be better off getting better short times. 10hp is about a tenth but dropping your 60 from 1.95 down to 1.85 is 3 tenths in a turbo car. AWD cars get down into the 1.5's with some work.
@@MotiveVideo So your still one of those noise maker guys. I know you have fast cars Hawkins but your in my world of small turbo engines and noise doesn't equate to performance. I picked up 65whp with just a tune and different fuels. I don't care about intake noise and the stock exhaust snaps and crackles a little, must be that I'm 50. I care about whooping arse
Last
at last?
If history has taught us anything.. it shud be safe to say.. one of the most common power mods for proper power is to do the rods.. it means u can push the car to the next power bracket.. go one step further.
Huh? Stock supra engine has gone low 9s. Stock RB26 bottom end has gone 9s and the list goes on. Bad tuning 20 years a fo is what broke rods. Modern tech and tuning means the days of needing rods and pistons early on are gone.
Chace, that is a next level stupid comment mate
asdf
Where is the fucken r33
patience. its a slow and very expensive build that we can barely afford
@@MotiveVideo :(
So leave it stock then
Hell no
Lets be honest the yaris is pathetic..
lets be more honest, your comment is
@@MotiveVideo The gr in the uk dose a 12.3 standard.. whys urs gutless.
