For: Hyundai and Kia SIM2K-341 ECUs. A file service: you send us the read, we return the modified file.
What this is
An immobiliser-off modification of your Hyundai and Kia SIM2K-341 file. With the immobiliser check disabled in the ECU software, the engine starts and runs without key authentication from the car's immobiliser system. Tuners and shops use it for engine swaps, bench and dyno running, and replacement ECUs that are not matched to the car's keys.
The work is done on your file; nothing ships.

FAQ
Why does it need a full read?
The immobiliser routine sits outside the calibration area, so a calibration-only read does not contain the code that has to be changed.
Will the car still need its original key?
No. With the check disabled in the ECU, the engine starts without key authentication. Other modules keep their own locks.
Who is this for?
Tuners and shops doing engine swaps, bench or dyno work, or fitting a replacement ECU.
Let customers speak for us
Solid shipping ,good communication ,great product 5stars all the way
First let's preface I have tried three other tuners. Not bad mounting or name dropping as they all were solid tunes. But Daniel just has that magic touch when tuning the 1.6 platform.
The car has a buttery smooth power band making the car feel like a larger displacement six cylinder over a turbo charged car. Plenty of fun to be had at any speed or RPM range.
He will take the time to get you dialed in perfectly for your car. No canned tunes here folks. And if you are a EK1 user three tunes for the price of one simply can't be neat.
I received the Stage 2 tune. Here are my thoughts:
- The shifts are buttery smooth
- I love the auto shift @2000rpm when cruising around town; saves me an extra 2-3mpg overall
- Driving in traffic is a dream now, much better than stock. I don't even hear that annoying shifting fork anymore, lol
- Any and all DCT slips are gone
- The increase in torque limit! This opened up my N75 Stage 3 ECU tune; I can feel the difference. The last time I dynoed, I got 289 lb-ft of torque. But it feels much more substantial than that!
- The clamping force is unreal. I did a run from a dig, and it hooked and slammed through the gears all the way to 7k rpm in each gear. Amazing.
Conclusion: This TCU tune is a must-have. If you have an N75 ECU tune, it is an absolute game-changer! Especially with the Redline MT-LV fluid that I'm running. I can't wait to get my retune with water meth injection. Daniel and the rest of the N75 team are the best!
Works like suppose to be fast delivery after installation 5 minutes drive TPMS sensors lights off everything is normal like from factory 👍👍👍

Product was very easy to install and what a difference in shifting also n75 was super awesome to deal with will shop here again
After using the N75 tune for a couple of months, I can confidently say that it offers the best value for your money on the market. I've tried SXTH and LAP3 tunes before, but since switching to N75, I won't look back. With top-notch customer support, it ensures your car performs better, turning heads at every car meet.
Been running stage 2 off that bat and had some problems here and their regarding fueling. Daniel has been with me the whole way, answering questions and adjusting tunes while adding revisions whenever asked. He answers every question I ask even when they don’t relate to tuning.
Highly highly recommend N75!
Daniel's tuning and customer service makes this product a 10 out of 10. I'm new to tuning and he made the process a breeze. I literally laughed out loud when I first drove the car after installing the stage 2 tune. I still can't believe the difference.
Love the intake, fitment is superb, instal was easy and best of all n75’s customer support is stellar and way above average!
