Clone PSA Delphi DCM7.1B ECU with Flex in Boot

Could Magic Motorsport Flex clone Peugeot Delphi DCM7.1B ECU? Or should I make immo off on the donor ecu?

Yes, you can 1:1 clone in boot mode. 

Boot read and write, job done.
Immo off also available.

It is a little more difficult with the point under the processor.
Work in boot but isn’t too easy, or make boot pin under processor or fully open ecu and search another boot pads.

 

Example:
Ecu Delphi Dcm 7.1B Ecu cloning with connection under processor. Job done

Autotuner and KESS3 will also clone Delphi DCM7.1A/B ECUs in boot mode.

BMW FEM Cloning Left Indicator Not Working Solution

Here we share a user’s experience with cloning the BMW FEM module.

 

Cloned a BMW FEM module with Xhorse vvdi key tool plus and Godiag FEM/BDC test platform on bench. The fault was left indicator didn’t worked.
So finally cloning was done, car starts but same problem. These BMWs when it’s registered short circuit too many times its permanently disable them.

The problem was the module detected short circuit too many times, and because of that it’s disabled the indicator. It prevents from damage of lights.
There is a short circuit reset option on diagnostic, but not working. Reset didn’t worked on two good diagnostics (Launch X431 and Autel), so last idea was to restore the Donor original eeprom, then of course needed to coded everything to start car and now everything work perfectly.

ISTA and tool32 can reset it as well.

Flex Cannot Write PSA SID807EVO ECU via OBD Solution

Problem:

Magic Motorsport Flex programmer reads Peugeot 307 SID807EVO ECU ok, but cannot write the modified file by OBD. It is a keyless system.

Error authorization from ECU failed.

Solution:

The keyless ones have to see the key in the emergency key position to allow operation.

Key must be in a coil detection area, that is why you couldn’t read.

Put key in the correct compartment and try again. Put key in the slot beside the steering.

Also if manual put it in 1st drivers seat belt on and hazards.

 

Optional solution:

Try leaving the ignition on even when it asks you to turn it off, or disconnect the battery for a while and try again.

Play around around with ignition on off timings. Don’t wait for flex, when it says ignition on click ok and then wait around 5-8 seconds before you turn it on. If you’ve done any resets with diag make sure ignition off for 2mins before you connect flex
Sid807 Evo if password protected can be done obd, if non password protected boot only, should still connect to update to latest software.

User feedback:
Disconnected battery for some time did the fix and worked.

Autel MaxiCheck MX900 vs MaxiPro MP900

Question: What’s the difference between Autel MX900 and MP900 diagnostic scanners?
I need something to read codes and do special functions on Corvettes 1997-2026.
Any advice on what to purchase?

 

Here is the clue.

The Autel MaxiCheck MX900 and MaxiPro MP900 are both 8-inch Android 11-based diagnostic tablets from Autel’s 900 series (released around 2023–2024). They share very similar hardware and core diagnostic capabilities but differ primarily in software features, with the MP900 offering more advanced capabilities typical of the higher-tier MaxiPro line.

 

Autel MaxiCheck MX900 vs MaxiPro MP900

Feature	MaxiCheck MX900	MaxiPro MP900	Notes
Processor	Quad-core 1.8 GHz	Quad-core 1.8 GHz	Identical
OS / RAM / Storage	Android 11, 4GB + 64GB	Android 11, 4GB + 64GB	Identical
Display	8″ LCD, 1280×800 touchscreen	8″ LCD, 1280×800 touchscreen	Identical
Battery	7700 mAh (~7 hours)	7700 mAh (~7 hours)	Identical
Camera	8 MP rear	8 MP rear	Identical
Connectivity	Wired (main cable), Wi-Fi (2.4/5GHz), USB-C	Wired (main cable), Wi-Fi (2.4/5GHz), USB-C	Identical; no Bluetooth VCI
Basic Diagnostics (Read/Erase Codes, Live Data, ECU Info, Freeze Frame, Active Tests)	Yes	Yes	Identical
Service/Special Functions	40+ (Oil Reset, EPB, DPF, Brake Bleed, SAS, Battery Registration, etc.)	40+ (same as MX900 + more comprehensive)	MP900 broader in practice
ECU Coding / Online Coding	No	Yes (e.g., BMW, Porsche, VW)	Major MP900 advantage
Guided Functions	No	Yes (e.g., VW/Audi/Skoda)	Major MP900 advantage
Hidden Features / Refresh	No	Yes (BMW, VW/Audi etc.)	MP900 advantage
Pre & Post Scan	Yes	Yes	Identical
DoIP / CAN FD	Yes	Yes	Identical
FCA AutoAuth / Renault	Yes	Yes	Identical
Vehicle Coverage	Wide (90+ brands)	Wider / more comprehensive	MP900 generally superior
Expandability	Endoscope (MV105S/MV108S)	Endoscope	Similar; MP900 may pair better with advanced add-ons
Price (approx., varies)	Lower (~$450–$550 range)	Higher (~$650–$750 range)	MX900 more budget-friendly

Autel’s 900 series represents a significant upgrade over previous generations (like the 808 series) with faster processors, more memory, Android 11, better screens, longer battery life, and support for modern protocols like DoIP and CAN FD. The MX900 and MP900 sit at different points in this lineup: the MX900 as a capable MaxiCheck model and the MP900 as a more powerful MaxiPro option.

Hardware: Nearly Identical

Both devices feature the same robust platform: an 8-inch high-resolution touchscreen, quad-core 1.8 GHz processor, 4GB RAM + 64GB storage (expandable), 7700 mAh battery, 8 MP camera, and dual-band Wi-Fi. They are built for shop use with solid build quality, responsive interfaces, and reliable performance for daily diagnostics. The main practical similarity is the wired connection via the main cable, which is reliable but less convenient than wireless BT models for some users.

 

Software and Features: Where They Diverge

Core functions overlap heavily—full-system scans, bi-directional controls, live data graphing, and dozens of service resets (oil, EPB, SAS, DPF, TPMS basic relearn, etc.). Both handle Pre/Post scans well for shop workflows and support wide vehicle coverage up to recent model years.

 

The MP900 stands out with professional-grade features:
ECU Coding & Online Coding: Allows coding for modules on brands like BMW, VW, Audi, Porsche—essential for post-repair adaptations or feature enabling.
Guided Functions: Step-by-step assistance for complex procedures on European vehicles.
Hidden Feature Activation / Refresh: Unlock or modify hidden options in vehicle systems.
Slightly broader and deeper vehicle coverage with more comprehensive service options in practice.

The MX900 lacks these advanced coding/guided capabilities, positioning it as a strong all-systems + service tool without the premium programming depth.

 

Who Should Buy Which?
Choose the MX900 if you need a reliable, cost-effective scanner for most daily tasks: code reading/clearing, active tests, service resets, and modern protocol support. Ideal for independent shops, general mechanics, or those on a budget who don’t frequently need ECU coding on premium European vehicles. It’s an excellent step up from older models like the MX808.

Choose the MP900 if you work on a wider range of vehicles (especially European) and require ECU coding, guided functions, or hidden feature access. It’s better for advanced diagnostics and will future-proof your workflow for more complex repairs. The extra cost is justified for professionals handling diverse or high-end vehicles.

Both come with 1 year of free updates (extendable). Always verify the latest coverage on Autel’s site or with your dealer, as software evolves. Consider your specific vehicle mix, workflow needs, and budget—many users find the MX900 sufficient for the majority of jobs, while the MP900 excels in specialized scenarios.
