Standalone Mapping
Here at A&M Conversions we have teamed up with Steve Greenald, who we have been working with for 8 years.
Rolling Road
With over 60 years combines experience at A&M Conversions, we can map the majority of today's aftermarket Engine Management Systems.
It enables a tuner to maximise performance and ensure reliability without any guesswork. The most accessible and practical way of achieving this is with a chassis dynamometer (Rolling Road).
All mapping work is done on our 1,200 hp TAT Rolling Road, a TAT Chassis Dyno Model CHD2 "V" High Performance, purpose built Dyno cell with our 25" fully computerized TAT Rolling Road, which can monitor vital engine parameters such as AFR / Lambda / Turbo Boost etc.
Our number 1 priority when choosing our rolling road was accuracy and consistency - we honestly believe we have the most accurate dynamometer in the North-West. Capable of accurately measuring over 600bhp (at the wheels) our system is capable of handling just about anything you've got!
This system enables us to measure very accurately the power produced from a vehicle and plot these measurements onto both a large-screen live feed or digital graphs.
For example, we can compare a dynamometer run today against a run completed 12 months ago, detailing the exact points of improvements achieved, and exactly where in the rev range those improvements are. Your car can have its own file that you can come back to and reference. Once a run is completed, we can also go into more depth - zooming into the graphs to e.g. identifing flatspots, or dangerous drops in AFR as a turbo comes on boost - producing reports for your own review.
A great number of serious cars have been successfully tested and mapped on our TAT Rolling Road - always accurate, never any wheelslip!
Mapping FAQs
Here are some common questions we get about our mapping process and rolling road. If you have any questions not covered on the list below please get in touch!
-
How accurate is your dyno?
It is incredibly accurate and consistent. Simply put, the results are as accurate as as anyone is able to produce, without using an Engine Dyno.
So far, we have performed well over 9,000 dyno runs and when compared against Engine Dyno data from the exact same engine, we have been within 1.5% every time - no mean feat!
For context, a 1.5% difference on a 200hp would be 3hp (this being the absolute difference, not the difference between runs. The difference between runs is far less)
-
How much power can you put down before the wheels spin?
The real answer is... we don’t really know! To the present day we have never had a car powerful enough to wheel spin on this dyno nor a car which made our Rolling Road run out of steam. And that's not for lack of trying - we have had some big ones down here! On one occasion we had an impressive 1180 lbft at the wheels on the dyno and still no wheel spin. The featured cars so far have been childsplay for our Rolling Road.
The Rolling Road’s manufacturer ratings are:
- 200mph constant, 880 hp at the wheels mapping,
- 1200 hp power testing and 4100 Nm torque (3020 lbft)
-
My car is very low, will you need to take the spoilers off?
As we have no Roller Lift, the car does not sink down once on the rollers, so therefore any car that can drive on the road or track, be it as low as it may, can be tested without any mods on our Rolling Road.
-
How does the car stay on the rollers?
We use a specially formulated fixing compound to hold the car securely in place.
It is based on an old recipe formulated by the old Druids which can only be harvested during a full moon and it is a solution consisting of ...
...Seriously: due to the geometry of the strapping, the vehicle under test becomes locked in a very stable position from which it is not able to move. Over 9,000 dyno runs have proven this to us beyond a doubt.
Comparison: Our Dyno VS Engine Dyno
They say a picture is worth 1,000 words - as you'll see from both pictures below, our dyno produces consistent and accurate results VS an Engine Dyno
