Warning Buyer Beware ECU Remapping ChipTuning Scams

Have you ever been reeled in by low prices, and then discovered that you haven't had the service you was expecting?

If it sounds too good to be true, it probably is. I’m sure that you’ve heard the phrase, “you get what you pay for”.

Recently, I did a bit of research into our ecu remapping competitors, and there are many. During my search, several operators’ low prices caught my eye, all with fantastical power gain and MPG claims.

On the surface their proposed service looks great, but read a bit deeper with an experienced eye and you will see that all is not what it seems, or indeed they would like you to believe.

For the inexperienced remapping is like a black art  Due to a lack of experience, potential customers, often take the bait of an alluring deal only to be left utterly frustrated in the end.

Please stay with me, and I’ll explain. Imagine you have heard about remapping and its various benefits, so you begin your Internet search for the best remapping deals in your area.

Great Sounding Remap Deals – Lure you in

There are some remap companies that offer seemingly fantastic deals. You may have searched online for a company offering professional tuning services. Or, perhaps you saw an advert by a remapping company promising “industry leading” power gains and even the promise of a live or dyno tune.

Remember These Words

With “too good to be true” remap deals, here are two words that you should remember: buyers beware.

Snake Oil - Look for Red Flags

Red flags for remap companies include claims like “ The UK’s Number One” Tuning Specialist or “Live Remaps”  or the promise of unrealistic power and MPG gains.

“The UK’s Number One.” Says who? Any individual or company that claims to be number one “Unless they have been voted number one” by an independent and recognised organisation, is bullshitting you!

“Live Remapping” On a standard production car with stock ECU, there is "NO Such Thing as a Live Remap” or a "Dyno Remap".

The term Live Remap relates to the car being driven on the road or dyno while having the engine management data altered, this can only be done with the engine running and is not possible without an aftermarket or piggy back ECU.

Immediately someone tells you they do live remapping or that a remap on a dyno is in some way superior, turn your bullshit deflectors on!

There are technical limitations and mechanical safety factors that have to be observed to have a happy outcome.

Read the reviews

The best reviews to consider are on a medium like facebook or similar, where the page owner cannot edit the feedback, and unless they have a lot of friends who can leave fake reviews, most of what you read is most likely pretty accurate.

Read the 1 star as well as the 5 star reviews

Why have people left 1 star reviews is it because they are competitors (yes that’s possible) is it because they are trolls (yes that’s possible) but on the whole it’s because they are not happy for one reason or another, so make sure you read them as well as the 5 star to get a good measure of the the remapping provider results.


Most websites or pages I have seen make a big deal about being insured, but is it the correct insurance cover? In my experience even tuners that do actually have insurance, don’t have the correct type of cover so if something does go wrong, you’re not actually covered anyway.

Mobile Remaps

There have been unethical practices by so-called remap professionals that have given the industry a poor reputation. There are some good mobile remapping providers, but nowadays that is more of a rarity. To offer a high quality, correctly insured service professional remapping companies have to make huge investment in equipment, software, insurance, premises, training to mention a few. Some people see remapping as a way to make a quick buck, and can unfortunately get in on the act for little or no real investment...

Typical costs to someone setting up as a mobile remap provider, on the cheap
  • No cost of premises
  • Buy cloned tools for as little as £40 off the internet
  • Buy so called tuned files off the internet for as little as £10
  • Operate from a mobile phone only (can replace it when it gets too hot with complaints)
  • Cheap or low cost website
  • Charge as little as £100 for a remap
  • When things go wrong they are nowhere to be found
  • No need to worry about reputation just get a new phone

Do you want someone cutting corners like that working on the brain of your car?

Here are a few tips to keep in mind
  • Beware of offers too good to be true
  • Watch for red flags
  • Read the reviews – Good and Bad
Realise that we get what we pay for. The least expensive option is not always the best

Choosing a Good Tuner is as important as choosing a Good Doctor.

You will be presented with a bewildering selection of companies, all claiming to be the best in the industry. Unfortunately the industry has been flooded with “Get Rich Quick” merchants all desperate to take your money from you. In many cases the “Get Rich Quick” operators have invested in “Cloned” counterfeit remapping tools off the internet. They have little “if any” industry knowledge, experience or liability insurance…

Don’t get sucked in by a good story and what appears to be an incredible price. Instead of taking the word of self-acclaimed tuning experts, a search on google will reveal some very interesting, yet disturbing facts about a few “so called” professionals. Unlike some testimonials “Bert for Bognor says we are Brill” our customers are real people. Don’t take our word for it, ask the people that know best “Our Customers”

I went for a remap on my T5 as it had an awful flat spot around 2800 rev's I got great personal service and its like having a new engine in the van smooth power and greater economy.... Highly recommended wish I'd done it months ago it would have paid for it self already thanks a lot hills are no longer a drag.

Popped in to see Mike on Friday to have my A4 2.0TDi 170hp remapped. Have to say I was a little pessimistic at first having being told by another firm that remaps on these were a nightmare so was expecting the worst! Thankfully, nothing of the sort, straight in, one error message unknown but Mike worked it out and all done in no time. Straight out for a test run and the drive is very different, certainly mid ranged (where these engines seem to suffer) pulls away nicely and can definitely feel the benefit. Best money I've ever spent on a car in, well, forever! Thanks again Mike

Had the ECU my 320D remapped by Mike yesterday. Very impressed with the results. Noticed it straight away after having it done. Service was also great, talked me through all of it to get exactly what I wanted out of it. Highly recommend mpg tuning.

James Aston

Took my Civic Mk VIII 2.2 CDTI to Mike following a recommendation from a friend who's had his last few cars remapped at MPG., professional service and answered any questions I had. Customised remap that gave me a good balance between performance and economy. Mike was happy to let me watch the whole procedure and explained what he was doing. Makes a good brew as well! Would highly recommend, Will definitely bring my future motors here.

Dan Wright

My boyfriend has exactly the same car as me 1.5 diesel fiesta, had his remapped and was over the moon with it. I had never thought of having a car remap but after driving his, mine felt heavy and slow so decided to get mine done too, now I am converted I love it even more and I am getting about 80-90 miles per tank better than before, very happy , great friendly service and awesome cuppa while we waited
