Jordi Renu – A Knowledgeable Rally Information Source

As a result of seeking out more information about the Blunik II, I have come in contact with a Spanish car rally expert, Jordi Renu.  Jordi has a rally business, called 325rally and is a pilot, regular rally co-driver with a great listener, and co-driver trainer.  He distributes equipment for regularity rallies including systems for automatic fire extinguishing and Blunik rally computer equipment.  Most of the thoughts in this post are based on things that he wants to pass on to rally teams.

In addition to selling equipment, he offers his clients advice, training and telephone support or support by e-mail.  He also offers personalized courses to each client, adapting to their needs.

Jordi has written to me saying that regularity control equipment is complex, and if the regularity rally concepts are not clearly understood, then it is very difficult.  For the most part, the rally equipment manufacturers only offer written instructions, and many customers have serious problems properly operating the rally equipment, thus not allowing these customers to fully benefit from this rally equipment.

He also notes that it often necessary to do a proper training course to know all the functions/roles of the team and go out to practice with a car prepared, with probes and measuring equipment with good tutors.

Blunik II Rally Computer

Regularity in rally requires excellent calibration of the device, correctly entering all the data of distances, speeds, changes of average speed and settings. Any mistake will lead errors on the road and be the source of a great annoyance. Doing rallies is not cheap, and if rally teams have to learn to operate rally equipment based only on rallies, then the learning process will be very expensive.  This is why Jordi emphasizes preparation and training.

Jordi Renu’s  Thoughts On How European Regularity Rallies Work

The organizer selects regularity sections, with a starting and ending point. It establishes one or several imposed speeds, which will vary from certain points of the route. For example: from the start of the section up to kilometer 2 at 50Km/h, from 2 to 5 to 47Km/h, and from 5 to 12 to 49.9Km/h

The imposed average speed can be driven in several ways:

  • Using the car’s speedometer (very imprecise)
  • Using an external or auxiliary rally odometer, a chronometer and a spreadsheet (very stressful for the co-pilot)
  • Using an external or auxiliary rally odometer and a calculator (stressful for the co-pilot)
  • Using a GPS device (a lot of random error)
  • Using GPS equipment + speed sensors (more accurate)
  • Using a dedicated system with wheel sensors without GPS, like Blunik (the most accurate, without random error due to loss of satellite coverage and internal error of non-military systems of + – 10 meters minimum)

And most of the dedicated rally systems are both complex in programming and in use. It is important to have a correct training to obtain the best results from the first day. If we do not do this, we will waste many rallies, time, and money before obtaining good results.

Jordi Renu always recommends that before buying a Regularity Rally device, you inform yourself well, have someone of your confidence to supply the equipment and offer you adequate support. And in case the seller does not help you, then look for someone who does.

The biggest problem that Jordi Renu has found is with the installation of the wheel sensors. Not all mechanics have knowledge about how to install wheel sensors, and it is not the first time that before starting a rally, after having moved the team thousands of kilometers, they find that the system not work properly due to an incorrect installation; more money thrown in the trash.

I became aware of Jordi Renu through Dan Allven of Monaco.  Last year Dan bought the Blunik II Rally Computer and he needed to know how to use it on a very short time frame in order to be prepared for the 2018 Rallye Monte Carlo Historique.  The Blunik factory referred this project to Jordi.  Jordi then contacted Dan Allven and offered his services to Dan.  Dan came from his home in Monaco to Barcelona and they spent 8 hours together between theoretical and practical training with the Blunik II.  This was very helpful to Dan.

Currently with Jordi’s courses, he has clients that with 5 rallies have gone from being at the end of the classification to being the top 10. Jordi notes that like everything in this life, it requires work and dedication.
