How to tell if VCM is good or bad?

I've done some small research about China Town VCM's and want to share my findings with you.

This picture is original Main Dealer Rotunda VCM


As you can see all circuits are gold plated and good quality components, metal casing with no production date stickers etc. on it.


These are most popular VCM clones you can get on china market at the moment:

Type A



Top Quality Ford IDS or Super Ford VCM (dual PCB)


This kinds Ford VCM has the same PCB Design as the original, but has Tin/Lead plated printed circuit board and different components(capacitors, some chips).Comes with metal casing with production date stickers.

can be used on the original software of Ford VCM Ford IDS (need crack), comes with IDS V86, Jaguar & Land Rover: V136  

Suitable for programming on all makes, DPF regeneration/replacement, key coding and relatively safe. Should be no problem with firmware update.


Type B


Good Quality Ford IDS (dual PCB)


The PCB of this kind Ford VCM is little different design with the original. Tin/Lead plated printed circuit board, metal casing, production date stickers.

Can support Jaguar & Land Rover, and can also be used on the original software of Ford IDS (need crack) comes with V86, Jaguar & Land Rover: V136

Suitable for programming on all makes, DPF regeneration/replacement, key coding and relatively safe.


Type C




Medium Quality FLY version with red relays (dual PCB)


The PCB of this kind Ford VCM is different with the original. Can't be used with the original software of Ford VCM. Metal or plastic casing with production date stickers.

Works only with modified FLY soft and FLY crack(_VCM.bfc 617KB for Ford IDS and MAZDA, _VCM.bfc 1907KB for JLR ).Comes with software version: IDS V80 ,JLR V130,MAZDA V79 but most likely they are modified old versions (V75,V128???) not confirmed yet 


Comes with FLY Switch as well so all makes can be installed on same system, not recommended for Ford and Mazda(system conflicts).


Ford IDS, Mazda

Not suitable for module programming (can corrupt/lock PCM, TCM), may work with other modules but you using it on your own risk, should work with DPF, key coding, injector coding. They have a habit of re-flashing PCM when you choose Self Test option.



Need more info about programming and coding possibility???


Type C 




Low quality copy with SONY chip inside (dual PCB)


PCB different than original Rotunda VCM. Comes with V75, V128 original Ford VCM soft (need crack). Metal casing with prod. date stickers.

Not suitable for module programming, not safe in use, not recommended!!!






Dual red PCB,Single red PCB's, Single green PCB's etc. just forget about and stay away from that scrap!!!


And one more thing, USB<->VCM connection cable must have small "Real" chip inside for Ethernet connection.


Check on, there only the one at the moment selling HQ VCM clone.

ISUZU 8971891360 (16267710 / 1.7L EDU) repair solution with pinout, pictures and explanations!


Check the capacitors

Check the transistor

Redo soldering (90% of fault)

"If your Astra 1.7 Diesel with an Isuzu engine has problems starting, stalling, or just does not run, the usual problem is the Diesel I ECU becoming faulty. Symptoms are complete non start or a spurious fault code blaming the spill valve.

We can now repair this problem and get car up and running again."

Opinions on BMW ICOM vs. BMW K+D CAN scan tool

This post collects some piece of opinions from experienced technicians on BMW ICOM and BMW K+D CAN scan tool, hope it helps.


Opinion1: A DCAN lead can do most things, but the ICOM is better with ISTA/D or ISTA/P


Those programs expect an ICOM unit, with the optical connector.


Most of the jobs can be done one by one with a Dcan lead, but ICOM is handier if you come across different cars.


With an ICOM and ISTA/D for example, you can plug into anything from an 8 series to an i8 and it will do everything automatically.

DCAN leads might need to be set up in K line, CAN mode, and wouldn't work on older cars that need an ADS interface.


Opinion 2. One of the real differences is that with a K+D Can cable access to some 663 (professional) radio modules is not possible whereas with ICOM can always communicate to this module. You'll encounter this problem using NCS Expert.


Opinion 3. Unless you are working on a lot of different BMW's professionally, ICOM is a waste of money. a $20 K+Dcan cable will do everything you need to do on a 2007 328....


Opinion 4. Icom is more reliable for flashing modules too. Less chance of getting a security access error
