XirDecoder DTC – Chip Tuning – All Solutions

Jul23

Today, car enthusiasts are looking for different solutions to enhance their vehicle’s performance and take their driving experience to the highest level. This is exactly where we come in! As XirDecoder Chip Tuning, we specialize in engine optimization and software updates. We aim to provide our customers with the best performance and lead the industry with our advanced technologies and professional team of engineers.

We are excited to introduce XirDecoder, an innovative chip tuning platform that’s revolutionizing automotive performance with the power of AI. Whether you’re a professional tuner or a car enthusiast, XirDecoder offers a robust solution for optimizing engine and transmission control units.

Key features and functionalities

  • DTC (Diagnostic Trouble Code) Removal: XDecoder allows users to disable or remove specific DTCs from the ECU, which can be useful in resolving issues related to certain sensors or components, according to OBDII365.com. This feature is also described as “DTC OFF” or “Fault Code Removal”.
  • Chip Tuning/Performance Optimization: The platform enables performance enhancements by modifying parameters like fuel injection timing, turbo boost pressure, and air/fuel mixture settings in the ECU It offers solutions for Stage 1-2 tuning
  • Emissions System Management: XDecoder can be used to disable or manage components like DPF (Diesel Particulate Filter), EGR (Exhaust Gas Recirculation), AdBlue, Lambda, and CAT (Catalytic Converter) systems.
  • Transmission Optimization: It also offers transmission optimization features, including DSG (Direct Shift Gearbox) optimization for smoother gear changes and launch control adjustments.
  • Wide Compatibility: XDecoder boasts a large database of over 130,000 files with unique DAMOS mapping technology for various vehicle makes and models
  • Additionally, if the uploaded file is not original, XirDecoder will detect non-original maps such as DPF or EGR and notify you. If desired, you can convert only the DPF and EGR maps back to their original state

How it works

  • Read ECU File: A master device is used to read the ECU’s file from the vehicle.
  • Upload to XDecoder: The read file is uploaded to the XDecoder software platform.
  • AI Analysis and Optimization: The platform’s AI analyzes the file and suggests tuning options, or you can select specific modifications.
  • Download Modified File: The system processes the file based on the selected options and provides the modified file for download.
  • Write to ECU: The modified file is then written back to the ECU using a suitable device

Considerations

  • Legality: The legality of modifying emission systems (like DPF, EGR, AdBlue) may vary by region and can have serious environmental and legal consequences. It’s crucial to understand and comply with local regulations before considering such modifications.
  • Risks: ECU tuning carries inherent risks, and improper modifications can potentially damage the engine or other vehicle components.
  • Support: XDecoder provides support for its users, including a system for creating support requests and chat with tuners
  • Software Activation: The software license is activated online and is linked to a specific computer.
  • Renewal Fees: Annual renewal fees may be required to maintain account activation.

Lessons learned:

  1. (OEM Key) word means Xhorse Key on the key tool plus.
  2. Original Key is customer key that you have.
  3. Have to hold a battery in the Xhorse key while reading or generating. Same with original key.
  4. Update the key BEFORE you generate the dealer key. There are a lot of different key options. Match the frequency and the picture then update.
  5. We removed capacitors and did not replace. Keys works as before.
  6. Bring replacement key shells. You will likely destroy the original key shell when opening. Plus it is a nice touch to have a brand new case on the customer key.
    I practiced on used remotes. Opening and reading key date before working on customer keys.

Xhorse VVDI Key Tool MIDI vs Xhorse Key Tool Plus

Jun6

Xhorse new tablet VVDI Key Tool MIDI is coming soon. What’s the difference between vvdi key tool plus and key tool midi ? Does key tool midi do all the functions of key tool plus ? Same add keys and akl car list ? Free life updates ?

Here is the clue

Basic Version: Support remote function(key tool function), VAG IMMO 1-4 generation, BMW CAS1-CAS3, programmer basic functions, regular IMMO models and TPMS functions.
Premium Version: Support basic version all features, add VW IMMO5 IMMO, BMW CAS4/FEM/BDC IMMO Functions.
Enhanced Version: All features of the advanced version. adding Mercedes-Benz FBS3 IMMO functions.

Key Tool MIDI TPMS Function

  • Support XTPMS Sensors(programming, activation, etc.)
  • 98% vehicle coverage for TPMS systems.
  • Long activation range, stable programming,OE-level replacement capability
  • Support multiple XTPMS sensors programming simulaneously

Here we compare the enhanced version with key tool plus full version.

VVDI Key Tool MIDI vs Key Tool Plus

These are the key differences:
1.Compact Design: They Key Tool MIDI is more compact and portable.
2.Integrated TPMS: MIDI has a built-in TPMS adapter for TPMS sensor programming/activation, while the key tool plus requires an external adapter for TPMS functionality
3,Limited PROG support: MIDI does not have PROG capabilities-it can only read basic 8-pin chips and some CAS,BCM modules).Advanced tasks will require VVDI PROG or MULTIPROG.Key Tool Plus PROG function will read eeprom, MQB cluster, gearbox,ISN,BCM2,JLR RFA,MB EIS etc.
4.Similar IMMO Features: IMMO Functions are nearly indentical across devices.
5.Cloud(C-Mode) Support: MIDI includes Cloud Diagnosis Mode-C functionality

Communication Error with Vehicle ECU On 2006 Nissan Pathfinder 2.5dci ?

May28

Hey everyone, hoping someone here can help!
I recently bought a Launch CRP919XBT and I’m trying to do injector coding on my 2006 Nissan Pathfinder 2.5dci but I keep getting this error!
I’ve double-checked everything — ignition is on, cables are all properly connected — but the message still pops up and won’t let me proceed.
Other functions on the tool seem to work fine. Just wondering…
👉 Has anyone successfully done injector coding on this model using the CRP919XBT?
👉 Is it supported at all? Do I need a firmware update or use a different menu/procedure?
Would appreciate any tips or confirmation before I go in circles again! 😅
Thanks in advance!

Solution:

1.When you choose Nissan it will ask for Market. Choose the Market the vehicle was originally sold in (not where you think it was made) then when selecting a Model you’ll have Navara (Spa), Navara (Thai), Pick Up, and some others. You’ll just have to keep trying models till you find the one that’s works.

2.More than likely incorrect model selected. These can be a PITA because you have Spanish Built and Thai Built both with different systems. I have done D40 Navara before with Pro3 (same software) but it took a bit of playing around to get the right software version.
