Looking for Rolling Road / Dyno Tuning in Staffordshire

Smoke and Mirrors

The idea of "dyno live tuning" is a controversial topic in the automotive tuning community often championed by keyboard warriors that simply do not understand the subject. The concept of dyno live tuning suggests that a tuner can make real-time adjustments to a vehicle's engine calibration while it is running on a dynamometer (dyno). The idea is that the tuner can monitor the vehicle's performance and adjust the tune to optimize it for maximum power or drivability.

Armchair Experts or The Bloke Down The Pub
Some of the armchair experts we see on forums say things like “I’d only ever get my vehicle live remapped properly on a dyno”. Live tuning an OEM ECU is a myth, a production car with a standard OEM ECU (Engine Control Unit) cannot be tuned whilst the vehicle is running.

Live Tuning Myth
Live tuning whilst on a rolling road/dyno, with the rare exception of specialized stand-alone ECUs, piggyback ECUs or emulators and can only be carried out when the engine not running, however, we often see misleading marketing that suggests otherwise. If a company has a dyno they of course have to justify the use of one, even if that means some make-believe benefits.

A dyno/ rolling road is simply used for measuring the power output, however, it’s essential when developing a true custom tune for a vehicle and can take several days to do so, during this time they would also be data logging air-fuel ratios, engine knock, boost, exhaust gas temperatures and so on to ensure that the new parameters are safe.

This is very specialist work, there are no qualifications for tuning, and just owning a dyno rarely means the facility has the skills to recalibrate OEM ECUs to a good standard. In most cases, they offer a remap with before and after dyno runs (referred to as pulls), and are often agents to trusted international tuning development houses that provide a data programming service to companies like us.

It would be like reinventing the wheel if the development has already been done and then someone with a dyno but not the knowledge starts fiddling with the parameters that have taken many hours to perfect.

Perfecting a tune for a particular engine requires a high level of investment in state-of-the-art equipment, software, and experienced programmers.

Simply having a dyno doesn’t mean that the tuner has a high degree of expertise and often doesn’t even do the tuning themselves. Personally, I would prefer some additional power provided by a tune that is safe, widely tested, and proven!

Some people do like to have the piece of paper either to compare results with their friends or convince themselves about the new power output of their engine, but the real test is on road/track performance. We don’t drive a piece of paper, do we?

How Accurate Are the Results from a Rolling Road?
A dyno is a good tool for comparing before and after results from a tune, however, across different manufacturers and types of dyno, results will vary wildly, but of course, dyno results are easy to cheat with so many variables, it makes it very easy to manipulate the figures in order for a company to promote their software as one that gives better results.

DSPORT Magazine carried out extensive tests across different makes of dyno and the results were up to 12% difference in the gains made, their conclusion was “While dyno figures provide a great point of reference, trying to compare the figures from one dyno to another is futile.”

A very important thing to consider is the competence of the operator is the entering of a correction factor, which needs to account for air pressure, tyre pressure, fuel quality, temperature, and humidity amongst other things to attempt to provide the same results, whatever time of day you take it.

Dyno testing should certainly not be used to compare one car against another or to compare the same vehicle across different dynos, especially given the variation between dynos and user inputs, even the tension used to strap the car down, and consistency with how the operator uses the accelerator opens the results up to manipulation, something as simple as how sharply the operator presses the accelerator can have a significant impact on the results.

Our tuning is dyno developed and proven in bespoke state-of-the-art development facilities, by some of the most experienced companies and individuals in the business, after 17 years in the business I would have had a dyno a long time ago if I believed they were truly beneficial.

Apart from anything else putting any car on a dyno is inherently dangerous, both to the car generally but in particular to the engine.

Of course, most cars don’t explode on the dyno, but some do! Is that a risk you really want to take for the sake of a piece of paper that might not even be accurate anyway?

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

Mark Patterson

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

Just had the ECU on my BMW 320D remapped and it is absolutely superb the power is unbelievable and the service is outstanding would recommend it to anybody he has transformed my car from 160 bhp to 207 bhp no smoke at all and the power delivery is awesome throughout all of the gears really happy.

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
