GR Yaris The EcuTek thread

If getting a good gasoline map is tricky, flex fuel makes that 10x harder though if done properly. But yeah, that would have been my goal, happy not to have to do it again though, it always takes some nerves and time.
assuming you still need to order the flex fuel kit however?

Just had 1000cc Bosch port injectors installed on my E30 Flexfuel tune + Artec turbo. The car runs very well and the injector scaling from Ecutek is spot on!
On my M5 the BMW ECU was very responsive to octane. You could introduce ethanol or octane booster and it would add timing itself with each pull. I'm curious how much adaptation the GR ECU allows with non flex fuel ecutek calibrations?

Results near end of video around 19min (+23whp)
the car does automatically add timing to the 93 octane tune if you add some ethanol for knock suppression

Interesting thanks for sharing the video. I tried E15 as a test and there was no measurable effect. This could mean a higher concentration is required to promote adaptation or there is a difference in behaviour between the Yaris and Corolla calibration or market specific settings (EU regs Vs US)

Thought I’d add my 2 pence in - mine has just had the 09 Design map installed, they’re using the ECUtek platform for the tune and app to flash by phone.
So far just a short 45 drive locally to get some logs to send over, but everything is good so far.

Hey how you doing ? I just finished instal the airtec oil cool , what temp do you have idle and normal driving never going above 80 degrés is it normal ? And i have max 4.5 bar pressure full load
The Airtec thermostat opens at 80c according to their fitting instructions, so that is 'normal' operating temperature.

It took a lot of self control not to put the box on the roof and take another photo

what boost levels is ecutec tuners running with stage 2+ cars hitting 330-350hp?
curious to know the boost levels there.

its all setup dependant. I did my previous car with professional shop TVS racing in NL - the setup took all day and in the end they said honestly that if you will run longer periods WOT car needs lower compression pistons. If your tuner don't know the use case the car will be used, or if they don't say to you to what driving setup it is built, it will be hit and miss.
I'm sure a professional shop can set you a map that can be used also on track. Of course, the higher the tune, the lower the tolerances are with materials, fuels, etc.
For my use case I prefer reliable and constant power vs. random peaks that perform poorly. Someone appreciates just high numbers, but that doesn't necessarily work well on track.
I think it's common sense that if you want to run the car flat out for 20 minute sessions you either massively step up the heat management or run at lower boost (or both).
