Autel IM608 vs OBDSTAR X300 Classic G3

Autel MaxiIM IM608 and OBDSTAR X300 Classic G3 which is better?   Here we show the comparison between two devices.

But you have to understand no tool is perfect and when you are choosing your tool you got to understand the capabilities and also the limitations .


Obdstar G3 Vs Autel Im608

1. Motorcycles
The G3 also does motorcycles and aquatic Vehicles as well. 

The G3 comes with the motorcycles cables so you get all these cables for Ducati,Yamaha, Harley, BMW, Honda motors etc. You’ll be able to program all these vehicles with the OBDstar.

Autel does not have it. It does not do motorcycles and aquatic vehicles.



2. Gateway

The G3 has built-in FCA Chrysler Fiat, Renault and CAN FD gateway connectors, you don’t need to buy separate gateway adapters.

G3 allows you to connect to Dodge Jeep Chrysler works excellent directly into the gateway like that bypass the gateway.  It’s excellent feature.



3. Immobilizer

We are going to start with the Immobilizer section. That’s the main things of these two tools.

G3 is for immo and programming.   Autel has been on the market for many years before the G3. G3 is a new products and we would say the database is a bit more robust on the outside.


For example:

Program 2016/2017 Toyota Camry, the key just fine but when into the remote programming it did not work under Camry menu. In fact it is capable of doing it but it most likely has to do with the market difference from Asian market to the US market, you can program the remote function under the GT86 Toyota and that’s cable to program the remote just fine.

But under directly under Toyota Camry it did not work.


OBDSTAR is going to out the R & D behind it and add all the vehicles we need to get supported.

You can see the list of all the vehicles supported uh on the immobilizer side and it is pretty good. Another thing is that OBDSTAR has no mercedes support yet, OBDSTAR said they are working on it. That’s another difference.

IM608 has good coverage with out being excellent. IM608 not only program the keys, but is an excellent scanner and can program a other units like ELV, dashboard, EZS, Skin, ECU.



4. Add-on function

OBDSTAR G3 is a flagship device you can add on all the other features.  You can add odometer correction, airbag reset, test platform and ECU cloning license to the G3.

Obdstar G3 License

Let’s go to the advanced ECU.  G3 can add on the same feature to clone as dc706. If you go here to Advanced ECU this is something this is where this tool starts to blow away everything else.

There is no competition to be honest.

ECU license allows you to write the PIN to it, you can also write the VIN, change the VIN number and correct mileage for some ECUs, G3 can do immo off on certain ecms.

You can reset the VIN on the radio you see that so if you get a used radio and then it gives you VIN locked that you can reset it.

When go to the ECU flasher if you add on the cloning function, it handles different modules as well body control modules. You can clone them and once you enter into these modules you can read
them and mofiye the untis.
They are good on GM ACDelco ECUs, it also does Fiat IAW 9DF, Chrysler GPEC2/3/2A, Hyundai SIM2-50 etc.
They have very good nice wiring diagram pictures. I like the quality of the images.

The test platform function allow you to do is to actually send the message over the CAN BUS network and actually turn that cluster on or active different modules like that are activated via messages and not just simple powers and ground.

Autel IM608 cannot do these things.  All these feature are not available on the Autel side. 



5. Update.

OBDSTAR they’re adding every month you’re going to be seeing changes more units more Vehicles being added.


If your subscription expires, OBDSTAR G3 will still work the options you have still work but you will not get updates. 

If your subscription expires, functions that requires online access will not working on IM608, for example Mercedes online password calculation, you cannot get new updated neither.

Of course you will need to renew your subscription to get current updates on both tools.

G3 subscription is cheaper than Autel.



6. Chips & MCUs

Another thing is the database on the amount of actual chips that OBDSTAR supported is not very extensive at the moment.

This is a new tool. This is being added on the monthly things. Autel has a much larger database of chips and mcus. Autel has a bigger database to that then the G3.

It can read and write a lots of chips and mcus with the XP400 pro programmer.



7. Diagnostics

Autel IM608 is not just a immo programming tool, it is also a full-fledged scanner. 

Autel im608 does have a full-fledged diagnostic tool built in so it does take advantage on that.  It has very good diagnostic capabilities and covers the Euro/Asian/US & Australian markets very well.

G3 is not a full-fledged scanner.




8. Remote Keys

Autel IM608 will also generate Autel universal ikey remotes. OBDSTAR does not generate remotes.



In sum:They both do the immobilizer function. The difference is the database. It is a lot more extensive on the Autel IM608. IM608 beats this tool on IMMO!

Obdstar G3 is a very good compliment to the Autel. You can grab the Obdstar every time is late model Dodge Ram. 23-24. Autel takes a long time to pull the pin and failed to program keys. The Obdstar pulls pin in seconds and programs the keys very fast as well. OBDSTAR has no mercedes support yet,they are working on it.
