GR Yaris The EcuTek thread

12th revision received this morning, so will do some logging late afternoon today. I haven’t had a chance to speak to the tuner but I wondered if it’s because the fuel here on the Island is so unreliable. I only found out recently that the stations use MMT octane boosters for ‘Super Unleaded’.
 
Hello everyone, just curious—do any of you know the boost level reached with your final maps from your tuners? At what point could it be said that the boost is reaching unsafe thresholds on stage 1(intake and exhaust), no springs, no cams.

thanks
 
Back on the want for more power lol...being that the remote ecutek kit is probs about the same as booking dyno time would everyone think they can do all the data logging and adjustments in one dyno session?
At litchfield this is....I know if I ask certain people there they'll say yes, but after other honest opinions

I had a Litchfield Dyno , then data logging remotely. This was due to the original Dyno map not running well after a few days.
 
I'm still waiting to see if anyone has been able to confirm the car is faster on track, the last tune I had, had the car making the exact same power as factory after it heat soaked essentially rendering the tune useless to me.

Anyone able to confirm with data logs or similar from trackdays/racing that their car gained some MPH over the pre-tuned state?

I would say any tuner that can't send a car out with a "good" map after it being with them in person for a dyno session isn't worth visiting. These people on revision 6,7,8, 12........... imagine taking that long to map a car remotely! and all the driving being done while mapping needs adjusting, no thanks. Just spend the day at the tuner and have those 6,7,8 revisions done after every run.

That's fine if they supply the kit for remote logging and revisions, but what's the point giving them £300 for the Dyno if it still needs further work and purchasing of a dongle?

Loads of cars on the Nurburgring claiming 300 plus hp, doing same kph than stock cars… there you go…

Limited to 230kph. A remap won’t change that but it’ll get to that figure quicker than a stock car.

I know that, but meant that checking arrival speeds at certain corners…it clearly shows that some tunes, don’t deliver vs stock map…
 
With a recent update EcuTek made to their software, a tuner send me a file as they usually do, but it bricked my ECU. Car's dash is like a christmas tree and could not start.
Looks like the patch tuners are applying to this new software is not compatible with older versions... so be carefull and let them test their modifications before installing them to your car if you are about to do any.

EcuTek was kind and picked up my ECU to fix it in their facilities... but I will be without a car for at least 2 weeks :S

Hi, What region and model year is your GR Yaris from?

Not that simple. Dyno doesn't cover most driveability related issues (not in the typical timeframe of a handfull of pulls at least), and usually also is at the ambient temp and humidity of that day while it has to work from - 40 to +50 °C...
Even if you get a standalone, you need a lot of iterations to get it working perfectly. Add in different fuel qualities, the variables go out of the roof.

ECUs have gotten a lot more complicated and apparently it's less copy paste as there isn't enough insight to let the ecu controls cover individual cars differences. Hope it works out for all...

It seems that Toyota made different calibrations for different regions. I am in Peru, and I experienced a similar issue, but the application allowed me to restore the original ROM and continue with the tuning process.

I still stand by the fact you have more chance of getting closer to the "optimum" map by being at the tuner making revisions on the dyno, instead of them sending you "revision 7.7" to drive around on while they revise your map at their leisure. But I guess convenience comes with its downsides, imagine spending all summer tuning your car! Yes I agree ECU's have always been complicated things, copy and paste is never the way forward, I don't think anybody here thinks they can flash a generic map from "Dave down the pub".

How's that milk float working out for you? Missing the smell of petrol yet?

Proper dyno tuning can take a lot of time and should be complemented with road tuning in such case.
There are hundreds of correction tables that when correctly done (lots of work), should be able to correct for variability between cars and/or readily be tweaked for the most common hardware upgrades. A quick dyno tune (<0,5 day) can extract extra power for a given individual, but the hardest work is making a resilient base tune that indeed can cope with being copy pasted and still work well, only needing to dot the i on a final dyno run. Guessing the wastgate control is causing headaches on this platform... If mk2 is better there (seems so from testdrive) that might be a compelling difference...

Never liked the smell of cancerous polycyclic aromatic hydrocarbons... mf works great as a driving tool and no tuning issues :p , GRY has the handling edge in winter though for sure.
 
How times have changed.... I remember my Evo 6 being on the rollers the best part of a day with ecutek... Tweeking/logging/analysis and numerous runs to get it spot on. 😎
