The E46 M3 has many technical highlights such as double VANOS - infinitely-variable timing control on both intake and exhaust camshafts, individual throttle butterflies for each cylinder with drive-by-wire throttle control and M Dynamic Driving Control, which allows the driver to select a 'sport mode' for the throttle, providing quicker response to throttle inputs. After an extensive development program on the E46 M3 the 25bhp increase provides a good improvement in top end power with a much needed increase in mid range torque eclipsing the power and performance of the CSL variant. We develop all of our software on the rolling road to ensure accuracy in terms of both power delivery and also to ensure fuelling, boost pressures and exhaust gas temperatures are all within tolerance. Our aim is for maximum power whilst maintaining optimum reliability.

I have considered getting my E46 M3 remapped for a number of years, but only just have I had it done. The reason for my hesitation was primarily, would I actually notice the increase in power, bearing in mind it's only a 25bhp gain.

Anyway, I bit the bullet. Firstly, I'd like to say how polite and friendly the Celtic Tuning engineer Scott was. Very professional, and knew what he was talking about, and explained that it was not about the horsepower gained, but the remap for this car would increase throttle response lower in the rev range.

Anyway, after Scott did his magic, he asked me to take the car for a spin. I can honestly say that I really was not expecting the change to be as marked as it was. The engine was always very strong, and the car has always been fast, however, the pick up in mid-range or even low rev range, is now fantastic.

I am delighted with the work that Celtic Tuning carried out to my car, and would highly recommend anyone to use them. If their remapping magic can make such a difference to my car that isn't turbocharged; if you car is, then you've got to do it!

Alongside the engine control unit (ECU) we are also able to provide transmission control unit (TCU) software to help further enhance your vehicle. There is a lot of limitation built into modern gearbox software to help hold back the power gains you are trying to achieve from your engine, our gearbox software overcomes this and helps transform the way the car drives. Some of the modifications include raising maximum torque limiters, faster gear shift speeds, increased clamping pressures to prevent clutch wear, increased engine RPM limiters and much more…
