ExTuner: added LSU ADV support!

lsu adv

An important event, we have added ExTuner support for the most advanced wideband oxygen sensor Bosch LSU ADV!

Unlike the previous version 4.9, LSU ADV has a wider operating temperature range, does not require calibration (more precise production) and is recommended for installation in turbocharged cars.

LSU ADV support added in the firmware version v1.58, and is already available to download and update your ExTuner!

We're back at work!

On May 30, 2023, we started having problems in business due to sanctions, and since then we have not been able to work properly, it was a shock. And so, today we are back to work in full!

Now we can accept payments in the following ways: Visa, MasterCard (Maestro), GPay, Belkart, MIR, and we also accept MIR cards from Russian banks without any problems! Just as before, we send cash on delivery and bank transfer across the territory of the Republic of Belarus.

We are expanding! CobraRTP + mirobuilds

We must announce the expansion of the production geography, and from this moment the company mirobuilds from France officially produce CobraRTP Honda Edition!

This means that our most requested product will be more accessible to customers in France and other EU countries, due to the growing demand for Honda OBD0/1 tuning solutions, which is increasingly difficult for us to satisfy alone!

CobraRTP Honda Edition R9. Latest for Honda OBD0/1.


We should inform you that we are finishing further development of solutions for OBD0/1, and start moving towards solutions for Honda K-series.

And the latest of its kind will be the new CobraRTP Honda Edition R9!

What’s new, unlike R8 and previous ones:

-New structure that has no buffer SRAM to be real time!

-The size of the board is smaller by 5mm

-More reliable hardware

-Added vertical board fixer

At the moment, this is the simplest schematic that has only one memory chip, no separate USB-controller and no FPGA / CPLD.

Modernization. Refusal of USB controllers.

After finding some time for research activities, we decided to simplify and thereby improve our main products based on ARM microcontrollers (STM32), which are FlashOnline, CobraRTP Honda Edition and MotronicRT.


All our devices with a USB interface communicate with a PC as a USB-COM bridge (virtual COM port). To do this, we used USB controllers as separate microcircuits, which are tasked with coordinating communication between the PC and the device's processor.

What has changed?
