The hand-held programmer stores multiple software updates including the original factory tune. It plugs into the diagnostic port of the tractor and uploads the desired software into the ECU. When we ship the programmer, it arrives empty because we prefer to custom tune each tractor individually. This means an easy two part process:
1) When tool arrives, you plug the tool into the tractor and perform a "reading". This step will download the fuel maps and tables into the programmer as a small file and allows you to email the file to our software lab along with your instructions for custom tuning.
2) When we receive the file, we will customize it to your specs and email it back to you. Now you simply connect the tool back to the vehicle and choose the "writing" option. In the case of multiple Ekotunes, you will choose which tune to upload.
Why custom tune each machine instead of a generic tune for all machines of similar make and model ? Most modern Ag machines have a certain amount of individual tuning or calibration done right from the factory, especially injector calibration codes. Also, depending on factory option for that particular tractor, the fuel maps are customized for those options. We prefer to customize the exact software your tractor came with to keep any individual characteristics intact.
I suspect your 6210R will be the same power output as North American models seeing as your country uses Euro 4 emissions similar to our Tier 4.
You can view a 6210R dyno chart here showing both stock power, and stage1 Ekotune power.

As you can see, the stock torque is quite respectable. It will lug down to 1600rpm before falling on it's face. 99% of our tunes will have the same torque shape as stock but with higher numbers. For special applications we sometimes flatten the torque curve, or in the case of newer CNH machines, we extend torque rise buy 200rpm because some tractors tend to fall off at 1700 rpm.
With respect to emission systems, you are correct but it's a double edged sword. On one hand, we enjoy learning and developing solutions for all problems but also desire to play according to local rules and regulations. We have developed EGR solutions for Tier3 machines as well as Adblue solutions for Tier4a CNH machines for the export market as well as a few Canadian provinces where off-road emissions are not regulated once the end-user takes delivery. I'm very suspicious of anyone who claims to have full Tier4B emission solutions since no after market tooling for reading and writing to those ECU is yet available.
Without question, the 8.1 JD engine is a puller. We're hoping to develop a common rail pulling tractor using the 8.1 as our power plant. The 6.8 is also a robust engine. In case you're interested, here is our pet project. This tractor is a 6920 (badged 7520 in north america) making 740hp to the PTO. "Witni" has pulled two seasons with no major breakdowns. It's amazing how well the driveline has held up.
The purpose of developing huge horsepower tunes is not for marketing this type of tuning to farmers but rather the R&D value. It's amazing how much we learn each season, not only about the fuel systems but any design weakneses will come to light very quickly. It's also a lot of fun!
Since you have fond memories of your 7810, here is a winning pull by a 7710 custom tuned for a customer with an appetite for risk, This tractor is equipped with IVT and making 300+hp to the PTO
Finally, with regards to your newly purchased 8370RT, time will tell how well they will respond to tuning. Tooling is not available for the brand new ECU in those machines. One thing is certain. We have been optimizing diesel engines for 10 years, with AG being our main focus with over 1000 happy customers. For the doubting Thomas' out there, I invite you to demo our service.
eko how does your hand held tuner work , we have a 6210r series wheeled tractor ,don't know what your numbers of it will be in the us , ours is developing its power on a dyno but seems very flat and lacks torque at lower end especialy when on vaderstadd drill , and we have a 8370 rt coming next june , is there any thing to do to them not worried about extra power just want the torque back ,like in the old ones old 7810 would pulla house down pity they could not not have the old 8 litre engine like my old 78 or 8520 , people talk of remapping to improve things , what it really wants is all this egr and particulate filters taking of and then they can breathe fresh air again
