Has anyone bought or used the cheap tuning boxes on ebay like the below?

https://www.ebay.co.uk/itm/BMW-Diese...frcectupt=true

seems like there are a few on offer around the £50-70 range and i have saw some good reviews / feedback from ebay buyers who have used them and wondering if anyone on here has used them.

Wouldn't touch them with a barge pole, personally.

Can't comment on that exact one, but for years there have been plenty such devices, which pretty much comprise of a few cheap resistors to trick the ECU into thinking various sensors are giving different readings.

Would i chance it on a £800 Peugeot HDI? Possibly

On a £15k or so F30? er...no.

Buy a tune box from a reputable company would be my advice

Same as with financial investments: Only invest/tune what you can afford losing!

If you can easily afford losing your engine - go for any tuning you see fit. Worst case - you will lose your engine.

Tiger Tuners!

Seriously just don't.

Not on eBay anymore, but they have an Amazon shop.

The Italian Box is the one you want. It's at the same sort of price point, but they work incredibly well. I have 3 friends that run them on diesel BM's.
There's a specific one for each Diesel engine derivative.
My mates 18d X1 nearly pulls as well as a stock 3.0d! And bimbling around he's seeing 60mpg.
He took me down south last summer for me to pick my new bike up. I drove his X1 at least half way. No word of a lye, nearly 300 mile journey & average was 75mpg. He did even better going home!

That’s not a tuning box though, it’s just a scam!

The box in the OP will increase performance, just not by as much as a decent box, and nowhere near as safely.

I have a blue spark box and I have to say I am.vwry impressed with it. Customer care is faultless. Can even be removed and reprogrammed for another vehicle.

Of course the one in the original post is a step up from that. Bottomline is you pay peanuts you get monkeys.
You buy something that you don't know anything about really and you most likely unlike MCM don't have to means to verify what it does. Could do anything, could do the job as advertised, could be harmful to your car or like in their case could do absolutely f all.

Yes Bluespark is probably the cheapest i’d recommend, although really it’s best to get the twin channel box which is £280, so for just another £100 you can get a DTUK or TDI Tuning box which are far better quality.

I'm very happy with the quality of this box. Don't think it could get any better and prob have the same gains from it as well..

How long have you had it? After a few months my Bluespark box clips broke and one of the screw heads that holds the cap on the box broke off. Also the circuit board and all the components are bare, leaving them prone to damage from vibration, heat and moisture, whereas the DTUK box has a Potted circuit board. Also DTUK boxes are made by DTE Systems in Germany and are fully TUV approved. Definitely worth the extra £100.

Oh dear, it says it's not compatible with my vehicle, such a bummer, I was really looking forward to putting one of those on my £50k car

But equally you can get a proper remap for ~300

Can you get a decent remap for that little? I thought they were about double that?

[Kal101]

As Pythagoras once said - Quality is like oats. If you want the good stuff it costs. However if you don’t mind something that’s already passed through the horse once already ……

Personally I’d pay the bit extra for a decent remap but your car your choice.

Most are around the £400 mark. Evolve charge £450 but that does include pre and post dyno runs. Looks good value.

Yup mine was £330 inc vat. And it’s been wiped by a software update and since reapplied for free.
