Best Tool to Clone Renault DC4 Gen1 TCU: X-prog3 or Foxflash

Renault Continental DC4 Gen1 gearbox TCU cloning review:

Renault Clio 1.2 88KW 2014 Gearbox Cloning.
Gearbox type: Continental DC4 Gen1

Foxflash:

Read ok on bench.

Write failed.

This specific version is encrypted and cannot be cloned with Foxflash. Also Foxflash Reads and Writes only Maps on Flash, no Eeprom!

Launch X-prog3:

Done with Launch PAD V Elite with X-prog3 extension, or use the Launch X431 ECU programmer standalone.

Read on bench ok.

Write on bench ok.

Flash and Eeprom perfectly cloned!

One tool cannot do all.

FC200 or FormulaFlash Which ECU Tool Is Better

Question: I wanna purchase a second programmer and I’m confused between FormulaFlash and CG fc200, which is better?

Here are some users’ reviews to help you make a better decision.

1).

I have Foxflash also and recently bought Formula. In my opinion, Formula is an updated next generation device compared to FC200.
Formula hardware is very similar to Flex but isn’t the same. For example, Flex is a two piece device, Formula isn’t. Software is totally different. It’s not a clone.
Formula have great and excellent potential but needs to develop. It’s only one year old.
I’m very satisfied with it for now but I hope it will become a great tool as it promises.

2).

I have both FC200 and formula. What one lacks, the other has.

3).

Fc200 is better as it has more ECU coverage but formula will be better in the future. Formulaflash has many built-in functions and keeps developing.

You’d better get both.

AutoTuner Update for GPEC4LM ECU BOOT and OBD Beta

NEW AUTOTUNER PROTOCOL UPDATE!

A new update is available for the Continental GPEC4LM ECU in BOOT mode, found in Alfa Romeo, Fiat and Jeep vehicles.

Key Features:
Type: Engine Contol Unit (ECU).
Readout: BOOT NR.
MCU: MPC5674F.
Read time: 3min.
Write time: 2min.
Checksum correction.
Backup creation.

KESS3 Update: Add OBD and Bench Protocols for GM ACDelco TCU

Alientech KESS3 released new TCU protocols- Cadillac, Chevrolet, GMC.

Boost your business with the latest protocols for ACDelco and Bosch TCUs. Work in OBD and BENCH mode — no need to open the unit!

• Read and write on ACDelco T87 and T87A, and Bosch T93
• Support for pickups, SUVs, and muscle cars from 2015+
• Customize shifts, pressure, and torque for optimal performance

TCU GM: new OBD and BENCH access for American automatic transmissions.

Expand your intervention capabilities on ACDelco T87/T87A and Bosch T93 control units.

UPGRADE 2.33

Thanks to the new protocols developed for GM transmissions, you can work safely on ACDelco and Bosch TCUs installed in Cadillac, Chevrolet, and GMC vehicles. Depending on the unit, you can connect directly via OBD to the ACDelco T87A, or operate in BENCH mode (on the bench without opening the control unit) on ACDelco T87 and Bosch T93.

Quickly and safely access a wide range of GM vehicles from 2015 onward: pickups, SUVs, and muscle cars with 3.6L, 5.3L, 6.2L, and 6.6L petrol and diesel engines.

With these new protocols, you can:

• Read and write TCUs safely.
• Customize shift timing, pressures, and torque management.
• Improve ECU-TCU interaction for smoother and more efficient driving.

Brands included in this development:

• Cadillac — 3.6L, 6.2L (petrol)
• Chevrolet — 3.6L, 5.3L, 6.2L, 6.6L (petrol and diesel)
• GMC — 5.3L, 6.2L, 6.6L (petrol and diesel)

Take the opportunity to expand your services on some of the most in-demand applications, simplifying your work and increasing workshop profitability.
