Has anyone used/got opinions on the "eco obd2" to save fuel?

Reminds me of the late 90's power resistor of justice, honestly anything that cheap is almost guaranteed to more harm than good.
If your truly after better MPG then all options will cost a little bit, any decent remap specialist should be able to advise you rough estimates of what an eco map will give you, then if you look on you tube there are many videos explaining various ways of saving fuel while driving. personally I've just come from a 2016 Astra diesel where my average was 65.8mpg to a 3 which if I behave I can get an average of around 46mpg so I'm noticing the difference but I wouldn't go back.

back to the point of the post if your tempted be careful as I think it might be a con

Thanks for the reply.
 I noticed it advertised online and just thought I'd investigate a bit.
I'd like more power/torque TBO. ;)

I've been speaking to my local master tech and power isn't difficult if you have the 120ps engine, basic eco remap will still increase your BHP by around 33% balanced map around around 47% and power map around 54% torque however is only around 9 to 12 NM more however he did say power delivery and general drivability are increased in all cases, a balanced tune will see extremely little additional stress on the engine because they 120ps and the 165ps are bolt for bolt the same only restricted via software in the 120ps version

I actually had a remap from "Remap Kings"
It gave me more HP but didn't make a difference to the torque.
So I had it reverted back, and TBF they gave me my money back.

if your remap didn't do anything I doubt that gadget would do any thing but damage the engine even a poor remap should out perform a generic plug in box

Indeed - most, if not all 'plug-in' devices (including ones that connect to the fuel or intake air pipes/ducts) are just snake oil products, as shown on Fifth Gear.  Utter waste of money IMHO.  Remaps can improve the performance on the gen-3 120PS car, but as has been shown, not by a great deal in real-world driving because the torque of the 163PS engine is no different to the 120PS.

To tap the extra power, it just revs higher and you have to thrash it.  You may as well buy the 163PS model and save the extra on the remap and the additional costs of insurance because it is a reportable modification.  Not exactly sure what can be done with the gen-4 car with the same power, given it is a very closely-related engine (just with the addition of the mild hybrid function to power the electrics).  In that case, I'd just buy the Skyactiv-X (180PS+) for the same reasons as for the gen-3 mapping, and you get better mpg.

Obviously this is not the same as more significant mods such as adding a turbo, etc.  A shame we in the UK don't get the gen-4 in 2.5T SA-G form like North America.

Skyactiv-x is a fair chunk my expensive than a 2018 skyactiv-g and 165ps costs more on average than a 120, plus remap, plus insurance trust me I checked but maybe that would be different if I had less grey hairs.
talking to a Master tech at my local dealer he said turboing a skyactiv is a faff though one of the other dealers have a a low boost supercharged motor running over 200BHP on standard internals though he did say its only running around 3psi of boost because much more the internals may well become externals
