Multibao Eco OBD OBD2 Economy Fuel Saver Tuning Chip For Petrol/Benzine Car Gas Saving (Green)

It’s great saves me 4 miles per gallon on average

Don’t buy this whatever you do. It’s a scam. It lights up when you plug it into your obd port but that’s all it does. It does nothing for the fuel economy or anything else. Go on YouTube and watch the video. Its wired so that the light comes on but nothing else happensI didn’t even want to give it one star but Amazon insists that one star is the minimum. If an item is rubbish we should be allowed to give no star at allSo l am railroaded into giving it one star unfortunately

Clicked by mistake. Was refunded with no quibles. Great service. Hence the stars. As for the product I won't be plugging this anywhere. I honestly think this is a scam item

Easy to fit good price, waiting to see if it makes a difference.

Seemed like a decent piece of equipment but I was unable to fit it into my Ford Ecosport. The port seems to be a different size or shape.....

I bought this for obvious reasons.Since installing it, I've driven over 1200 miles and have seen absolutely NO IMPROVEMENT to the fuel economy in my car.The only thing the device seems to do is light up when the ignition is on.It's only a few quid, but keep your money and buy a couple of coffees instead.

Seems to be working ok ,not a high mileage user but vehicle is smother.(automatic)

Bought this in the expectation that it might be able to save some fuel. Once you open the pack its obvious it does absolutely nothing, but if it makes me look at the way I drive to save fuel then its been OK.If you do fit one make sure you unplug it before getting your car serviced , as I expect most car manufacturers would love to use it as an excuse not to honour a warranty
