Yep spot on, had horrible boost cuts and lumpy running on my DTUK box, took it off after a week. Loads of second hand boxes online which says it all really
Yes mate, thankyou for sharing this!! Totally agree
I use dteuk for about 2 years now, all works really well
Just to add, I have been working with a tuner for about 2 years and came to the same conclusion. Its possible to tune on the oem ecu for single runs like at the traffic lights etc but on track as soon as the car is getting run hard it makes almost factory power.
Exactly, thanks mate
Awesome. Thank you 👍👌
Thank you too!
Thanks 👍
My pleasure!
Hey A, thanks for the great video, so my car is mapped by one of my friends knowing denso ecu very well , we ran the car on the front wheels only and achieved really good results, but once on the road the car took out power aggressively, after realising that we went back and got it eventually sorted by adjusting torque limits in the 4wd , car runs great consistently now , just some data , it ran 16.6 sec 100-200kmh stock ,then after the map it now runs 13.8 seconds consistently, I kept it moderately on the tune, he said there is still more to get out but i left it at 250kw it ran 200kw on the base run with only exhaust
Cannot wait for ECUteck🤞🏼
Thankyou for this great information, sharing your experience: I am happy you also saw first person!! Please let me know how the next step goes for you with Ecutek!
Good day! Insanely good video! Thank you. For days now, I've been looking for so many hours a day which chip tuning (or tuning box) I should do. But what great information!
I come from Germany and my English is not perfect, but is it summarized correctly? :
-No tuner can currently offer good chip tuning because they simply overwrite the existing program but keep tuning the car down for safety reasons? And you basically don't have any real increase in performance?
2: Lichtfield is the only company that has recently been able to do a reasonable mapping because they use other software and you can hand in your control unit there?
Please answer or advise what I should do now to get more performance, as of today?
Hello Peter, thankyou for that!
Let me clear it out: tuners use software made by third party to enter the ECU, then individually tune the car.
Today there are two main softwares available:
- Alientech (not what you want)
- Ecutek (this is ok)
Find an Ecutek dealer, they will be able to tune your car well.
All tuners that use the other software, even if they are great, can’t keep the OEM software from coming back and intervene on the new settings.
Hope this helps and is more clear!
I have used jb4 with their bcm module - works well and gives 295-310hp (i have only mild setup, not getting all out) - for my use for fast road/track it works well. Trust it more than bad ecu tune.
I have had something similar, but for me the benefits are negligible and the response varies a lot, depending on outside temperature, altitude, etc…
well stock engine does the same. @@AJClubsport
I had similar problems with the Litchfield chip. Fantastic when it was working, but particularly at the track the chip would throw a code and cut boost.
Yes, exactly the interference detection by OEM software!! Cheers Matthew
was that the Lichfield box or remap? I have been considering the ECU map from them, but this very well argued presentation gives me doubts. I am GR 21 8000miles
Litchfield now does EcuTek mapping on stock Ecu, no problems!!
Thanks for the video! What is the idle like on the EZ cams? Who mapped your car and did they use Ecutek? Cheers
I am waiting on the cams install and map for Ecutek to release the next step in software with added features and muli-maps. All work done by ACME Racing.
Idle is like stock on EZ and A profiles, no information about the other profiles
@@AJClubsport thanks mate!
I have a hks box . This ups boost ive been told this is a good option . Not a dtuk box . Hoping to go ecutek eventually
It will be a BIG step!
I kinda like the idea of box. If my understanding is correct, that way you get extra power but the ECU has a final word safety-wise? I have DTUK (306hp, 412Nm), but had it's harness re-worked as I suspect the loose pin connections threw Boost pressure sensor error code once every few month. Didn't test it yet with renewed harness.
Most probably it isn’t the wiring: it is the ECU not happy with the requests coming from the external box. Try to lower settings and it will work
@@AJClubsport Happened to me once with the box turned off but wired in car, so I doubt it's about setting. One of the guys working for Rimac repaired the harness and told me there were signs off loose connection sparks. Strangely, read about exact same ECU error code on few stock cars in last few month.
@markos8400 wow, that is something new to me!
Grazie Adriano, possiamo mappare anche macchine stock? Intendo con tutto di serie? Grazie
Grazie a Te! Certamente, potrai raggiungere risultati stabili e ripetibili in tutte le condizioni!
I'm in Australia, where can I get the ECUTEK tune for it?
I think the best option is to google it mate, you should find a distributor there!
Interesting, the dyno we've used on my car has never had a problem in awd mode. That is not to say you're wrong though. Just that it seems there are at least some kinds of dyno that work in AWD that can give consistent results. 😁👍
This is interesting: so you got consistent back to back runs in 4x4 mode? You are the first I hear from. Was the dyno in locked mode?
I dont know too much about it, I can ask the tuner but when I explained the potential issue they said "dont worry all the rollers are linked" they were able to do 10 or so runs with me there during the last tune and got the same power within 5-10bhp through the power curve. I can ask them what type it is if you want.
@BanzaiYaris linked is what I was intending, and also you replied: this 5-10hp difference is all the problem mate! It oscillates because the traction control unit (TCU) starts doing strange things when its in 4wd mode!
Good info Adriano, can I ask if there would still be issues when you go in for Toyota updates ? They ask if I've had it mapped each time , I understand it can wipe any re-map thats been done. I'm probably not going with any re-map
but who knows in the future.
Regards Russ..
Cheers Russ: just went in to Toyota on Friday and no issues. They did connect to diagnostics and also made an update to the SOS system upon a recall
Cheers Adriano, yes same thing I've been in 3 times for updates due to early car, I'll ask again to make sure, Are Ecuteck a UK based software firm ?
@AJClubsport Toyota told me any remap on the car would be overwritten due to having a substantial ECU update (2 year service) on Monday,surprisingly the car as become more responsive and feels quicker since having this scheduled ecu update by Toyota,definitely a surprise to me.
As far as I know, Syvecs is the ECU of the GR Yaris Rally Cup cars. So, this must be the absolute best, no money considered, solution. Ecutek then is a more affordable quality option. Did I get it right?
Exactly mate, Syvecs/Motec best overall. Ecutek very close results, sustainable and repeatable!
What seems popular in Japan and the rest of Asia is ECU tuning using Alientech. Any thoughts on these? Today I am using RaceChip GTS and it seems to deliver a noticeable difference. I am also curious about the Kelford cams and springs. As I understand this must be used in conjunction with ECU tuning and is not just a drop-in or bolt on solution - am I correct?
If you drive the car hard enough, you will see that the tuning box will vary about lot in performance output, depending on outside temperature and altitude
The Alientech doesn’t manage to exclude all the under-maps in the original Evu software, therefore it constantly shifts beneath what you program and doesn’t absolutely offer consistency. Ecutek should work great also with cams, it will be done in the next two weeks
Hey Adriano, first of all thanks for the good technical content you provide. Keep up the good work.
I'm currently on a custom map for 3500km now with 340HP/450NM and just bolt ons and didn't run in any sort of issue yet. For the 2025 season I'm thinking about upgrading the motor like you to go for around 420HP but not much over the current torque because we all know the car doesn't like that.
I'll drop in the beehive springs and 267-A cams from Kelford, turbo upgrade, head studs and upgraded head gasket. What studs will you be using and what gains are you expecting from your build plans? I'd love to hear your thoughts on this.
Hi there, thankyou for your comment!
Your plan seems to be very good and ambitious! I suggest to check out @ctecperformance
Nigell is around the end of development of the most well engineered turbo kit I have seen for GRY, with long runner headers and two turbo options 450 and 550bhp.
I’m happy your stock ecu map is running strong, it’s a lucky one and for sure you have great fuel where you are!
@@AJClubsport Thank you for this suggestion, I'll have a look at it. Unfortunately I can't run an aftermarket turbo setup because our TÜV will notice 😄 My current setup has full TÜV coverage. You're right, here in germany I've no issue finding 100 or 102 octane fuel. Do you have a suggestion for the head studs? Will H13 tool steel keep up with this kind of power?
@@TheOriginal99yes, they will be fine as head studs. I got Lamspeed
@@TheOriginal99 in Germany as well, care to share your current setup? I am on a DTE box with low settings, Milltek exhaust, Airtec oil cooler. The DTE while not anything dramatic always gives me at least 1 sec better lap time and while I have not measured my car I’d say it’s close to 300hp, would be interested for 340hp. TIA
Good newz for Ecutek ! I remapped mine because I had inconsistent boost when stock (sometimes it won't go over 1 bar of boost). Now it's gone but i still feel some inconstencies on the road. Also, the Yaris has a 2WD dyno mode included :)
Yes exactly! But you should really understand what is the issue there is beneath: boost cuts on stock map point to a real issue of some kind, beware!
Use a linked 4WD dyno system (IE dynojet) and you wont have issues running with proper 4WD. Our GR yaris development is consistent run to run with sort of dyno, I wouldn't bother wasting time on unlinked small roller dyno that is inferior, nothing but issues for this sort of application. Syvecs is cheap upgrade for the features, consistency and security you can have on the car. ECUTek is good too, but always fighting stock ECU strategies. Hard for me to recomend at this moment, better to not waste money and save for standalone in my opinion. As ECUTek develops it will become more robust so there will more chance to get people an alternatirve, this is always the life cycle of development for new platform.
As was mentioning in the video, EcuTek is on the verge of a major new release that will enable full control, so no more fighting the stock ECU! And this will also enable multi maps and OBD writing.
We tried on two different dynos, both linked rollers, and it didn’t work for us, as for many other tuners. Given the possibility of running the car in FWD mode, it makes no sense not to while on stock Ecu, in my opinion.
Cheers
@@AJClubsport I have no issues with stock ECU on dynojet linked. Nothing but issues on anything else is my experience.
Yes new update will be a step in right direction, time will tell
Cheers mate!
I'm probably $2,500 into this focusing on what was found to be snake oil. I did not run an aftermarket intake or airbox, but you know the drill. 4WD is so tricky to dyno on stock ECU. I had good stock numbers but after adding parts, I lost power. It's the truth and a lot of these companies either cherry pick and dishonest or the mileage may vary during testing.
New cars are hyper complex and a standalone seems to be the only constant to control these conditions aside the other expected anomalies that could happen with dynoing.
I understand: best is stock or Ecutek with full control, disabling all Oem sw. This appears to be possible in the current Beta
Don’t go over 420NM with stock rods 👍
I had no head lift at 400HP and 500NM but after 20k KM the rod on cylinder 1 got fatigued and broke. I’m forging the engine right now 😂
Thankyou for this information: it seems that you may have run into detonation, because there are many cars out there, including mine, that have been running strong on stock rods at 1.8bar and over for over a year now…
Thanks for the no bullshit video, at last someone talks with facts why most tuners sell snake oil in the end. Still I have to say that running the DTUK (or DTE in Germany) box in the conservative settings for 1 year with at least 2k in track/drift events I have only had only a couple of times throwing an error code and I consistently see at least 1sec of improvement in my lap times (in the same track and same day event so comparing apples to apples). I also almost always have it deactivated in the city, using it only during track time and maybe autobahn where 230km/h in Germany will not cut it! Not sure what a quality next step for additional hp would be (looking for 320-340hp range, nothing that I will need to open the engine). Oil cooler installed, transmission cooling mods as well, next step is suspension.
Cheers mate, very big news is coming from the suspension compartment soon (within a week)
Lift will come with 280hp and 390Nm of torque. I think it might be the sweet spot for this car. I think for tracking car the best map is always stock one:).
Yes, or a very well done map and all additional cooling/supporting mods
@@AJClubsportstock map is always very good and safe. Of course when mapping Your car more power means always more heat (and heat is killing the engine) so intercooler and oil cooler is must have modification. I dont have experience with GR (but i really want to buy lift) but with another cars i owned i have bad experiences with custom maps, tuners always pushed the engine to the maximum chasing the peak Numbers and in the end it ended with engine damage or with the lack of performance on the track by cutting the boost and timing. Now i am using OTS map on my car, that map was tested for several months on road and tracks and i am pretty pleased with it, it works, car is smooth and zero problems;)
@piotrwozniak7840 yes, I agree: this is why I talk about power that is always the same in all conditions. The GRY gets very hot, this is why we developed the hood vents to extract hot air, both WRC and Rally.2 versions. What do you intend by “lift”?
@@AJClubsportby lift i mean refreshed version which will come in the middle of this year. Toyota made great changes in refreshed version of the car (also better cooling). I want to sell my golf 8R and get GR 😊
@piotrwozniak7840 ah ok, in that case its a great idea!
So many videos on yt of different gr yaris that claim 320-350 hp and when you look at the acceleration numbers theyre clearly far from a car with those power numbers
Exactly, a lot of bullshit out there!!
They also offer 1 year warranty
Who does?
@@AJClubsport litchfield on the ecutek remap
Yes thankyou, that is very reasonable
I try to contact you Can you tell me how?
Hi Ron! adriano.piras1@gmail.com
Interesting to order hood vent wrc1 and WRC 2. Thank you
Hello Ron, I didn’t receive your email, did you see the address? adriano.piras1@gmail.com
Golf 7R ecu its 10times more advance then yaris.Tuner just need more times for understands all maps and tricks in Yaris ECU.
We are almost there, beta is finishing in the next two weeks!
