Inauguration of the new official website of PerfecPower on Thursday, May 1, 2025!
IMPORTANT: The site is not yet finished, there are still a certain number of pages to migrate from the old site to the new one, which will take a few more days, thank you for your understanding. However, you can still visit the old site in the meantime: https://www.perfectpower.ch
Drop of the official price of PerfectPower as of Tuesday, July 1, 2025!
PerfectPower Android at 33 euros & dollars instead of 49 (- 33%)
PerfectPower iOS at 27 euros & dollars instead of 39 (- 31%)
This drop follows the results of an interesting statistical study conducted from January 1, 2025 to July 1, 2025, whose you will find the report in the Stats section (up to date as of July 1, 2025).
Release of PerfectPower iOS 6.1 planned between July 11 and 13, 2025
Priority development of PerfectPower iOS (from V6.1 to V7)
15% off at the RaceBox store with code BOX-M15 thanks to the PerfectPower – RaceBox partnership!
V) Friendly challenge at 10,000 euros & dollars
I) PerfectPower Androïd
Current version: V 7.1.3
1) Driving the RaceBox Micro (following the RaceBox Mini -V6.1- and Mini S -V6.1.4-)
2) Correction of the frequency calculation in the case of sending split data packets (specific processing carried out in version 6.1.5) ==> From now on, the GPS frequency returned by PerfectPower strictly corresponds to the exact frequency of sending information by the RaceBox (all types) and in all cases (full or split packets), i.e. 25.0 Hz typically.
3) Optimization of the devices scanning process, in order to prevent the accidental connection of 2 RaceBoxes at the same time, which generates a conflict and prevents the correct reception of information from one as from the other!
4) Customization of all texts regarding the driving of the 3 RaceBoxes (scan, connection, disconnection, etc.) to clearly distinguish them: from now on, the exact RaceBox model will always be specified: Mini, Mini S, or Micro.
5) Delivery of a promo code inside the app allowing PerfectPower users to benefit from a 15% discount on all products in the RaceBox store (RaceBox Mini, Mini S, or Micro all three driven by PerfectPower, but also the RaceBox Pro or even RaceBox accessories!) thanks to the PerfectPower – RaceBox partnership!
Upcoming versions
V 7.1.4
1) Addition of a double choice of graphic scale for power graphs (in both Portrait and Landscape modes):
– Absolute vertical filling of the screen: “Power (90%) / Torque (50%)” (current) or “Power (90%) / Torque (90%)”
– Relative vertical filling of the screen: “Natural (axes starting from 0)” (current) or “Max size (curves occupying all available height)”
2) Aesthetic optimization of power graphs (in both Portrait and Landscape modes):
– Adaptations to all screens of the position of the PerfectPower logo and header texts
– Re-definition of the areas reserved for graphs (larger) and header texts (smaller)
V 7.1.5
1) Aesthetic improvements:
– Addition of logos associated with the types of measurements performed
– Implementation of two meters: instantaneous speed, instantaneous power
V 7.1.6
1) Addition of the informative fields “Engine inertia”, “Wheels inertia”, and “Total inertia” in the car sheets and the power results sheets
2) The configuration of the performances simulator (shift time) is now associated with the car and is therefore done in the Car sheet and no longer in the Setup
II) PerfectPower iOS
Current version: V 6.0.3
Intermediate version without changes, but intended to warn users in the home message of a major change in the next version 6.1 which will be released on July 13, 2025
Upcoming versions
V 6.1
1)New memory data recording system, more efficient (more disk space available and faster data transfers) and more flexible, allowing in future developments (in chronological order):
– The increase in the number of results per type and per car (20 currently)
– A possible evolution towards data storage on the user’s iCloud account, allowing data sharing between user’s phones and then data transfer if he changes phone
– A possible evolution towards the creation of a Car database directly integrated into the application (this will be the last major development of PerfectPower)
2) Complete revision of the program for the implementation of this new system (complete modification of the structure of the data sent into memory, including changes in variable types), AND to allow both the addition of the function of re-calculation of the power results after measurement (V 6.2) and that of a new “GPS only” measurement mode (V 7.0).
Note: This update actually represents a colossal and also very complex work, and despite the immense efforts I made to make the data of the old system (V <= 6.0) as compatible as possible with the new one (V >= 6.1), I regret to announce that all your measurement results (power, accelerations, and runs flying start) will be lost at the first opening of this V 6.1, so please remember to take screenshots of all the results you want to keep BEFORE installing this version, thank you for your understanding! FYI, it was absolutely impossible to do otherwise… On the other hand, all your setup and car data will be preserved.
V 6.2
1) Addition of the function of re-calculation of the power results after measurement (very useful in the event of incorrect initial configuration of the Setup data and/or the Car sheet)
2) Addition in the power results sheets of the three chapters “Warnings”, “Measurement accuracy”, and “Miscellaneous”, and their information (5 in total)
3) Addition of the Braking function
V 6.3
1) Addition of the power measurements comparison graph
2) Addition of the power measurements averaging graph
3) Addition of the function of generation of a new averaged result for power measurements
V 6.4
1) Addition of the accelerations measurements comparison graph
2) Addition of the accelerations measurements averaging graph
3) Addition of the function of generation of a new averaged result for accelerations measurements
V 6.5
1) Addition of the function of generation of a new averaged result for runs flying start and braking measurements
V 6.6
1) Addition of the Speed, Rev calibration, and Losses measurement functions
V 6.7
1) Driving via Bluetooth of the RaceBox Mini (external GPS 25 Hz), allowing:
– to further increase the accuracy of PerfectPower measurements (especially the runs flying start)
– the use of a new “GPS only” measurement mode for power & accelerations & braking measurements, which will be added in version 7.0
V 7.0
1) Addition of a new “GPS only” measurement mode (power & accelerations & braking measurements) allowing the only use of GPS data and therefore allowing to get rid of constraints of the accelerometer, thus allowing:
– to perform power measurements on a rolling start (indeed, the accelerometer calibration phase at standstill is no longer necessary!)
– to no longer have to carry out the accelerometer calibration phase while driving for braking measurements
– to completely free the phone from any mounting requirements (stability, vibration level, positioning)
However, the use of the RaceBox Mini is essential to use this mode, the internal GPS of phones still limited to 1 Hz in 2024 being still far too slow!
V 7.1
1) Power / Mode 2 only: Addition of a function of results correction on road slope, with indication of the average road slope and the max correction applied
However, the use of the RaceBox Mini is essential to use this function, the internal GPS of phones being much too inaccurate for an accurate correction!
Moreover, this function is NOT a magical function allowing to exempt you from performing measurements in both directions of the road since although it compensates with impressive efficiency for the effects of road slope, on the other hand it does not compensate for those of the wind (just as important!) AND therefore it remains ESSENTIAL to perform measurements in both directions of the road and average them to obtain perfectly reliable results, thank you for your understanding!
V 7.1.1
1) Addition of a double choice of graphic scale for power graphs (in both Portrait and Landscape modes):
– Absolute vertical filling of the screen: “Power (90%) / Torque (50%)” (current) or “Power (90%) / Torque (90%)”
– Relative vertical filling of the screen: “Natural (axes starting from 0)” (current) or “Max size (curves occupying all available height)”
2) Aesthetic optimization of power graphs (in both Portrait and Landscape modes):
– Adaptations to all screens of the position of the PerfectPower logo and header texts
– Re-definition of the areas reserved for graphs (larger) and header texts (smaller)
V 7.1.2
1) Aesthetic improvements “Part 2”:
– Addition of logos associated with the types of measurements performed
– Implementation of two meters: instantaneous speed, instantaneous power
V 7.1.3
1) Addition of the informative fields “Engine inertia”, “Wheels inertia”, and “Total inertia” in the car sheets and the power results sheets
III) Future developments (PerfectPower Android and iOS 7.X)
1) Export data to a CSV file
2) Optimization of the memory management, allowing the import / export of data between phones
3) Optimization of the performance simulation:
- Optimization of the grip limit calculation with modern sport tires
- Automatic delivery of reference flying start runs measurements following a power measurement (40-80 km/h & 25-50 mph, 80-120 km/h & 50-75 mph)
4) Addition of a TUNER option, allowing to enter logged engine parameters and to have PerfectPower calculate the engine efficiency in the form of specific consumption (different modes and units provided)
IV) Projects
Creation by end of 2025 of:
1) PerfectPower Motorcycles (adaptation of PerfectPower to motorcycles)
2) PerfectPower Bicycles (adaptation of PerfectPower to bicycles, with the measurement of instantaneous and average muscular power during a sprint)
3) PerfectPower Sprinters (adaptation of PerfectPower to sprinters, with the measurement of instantaneous and average muscular power during a sprint)
Note: Although the use of the RaceBox Mini will not be essential for PerfectPower Motorcycles (just as it is not for PerfectPower), it will however be essential for the two other projects, thank you for your understanding!
V) Friendly challenge at 10,000 euros & dollars
Translation coming soon… but you can use Google Translate in the meantime!
En tant que créateur de PerfectPower, j’affirme que:
- PerfectPower V7 est encore plus précise en résultats moteur que n’importe quel banc à rouleaux dans le monde (Maha, Rotronics, DynoJet, etc…)
- PerfectPower V7 est plus précise en résultats moteur que n’importe quelle autre application smartphone (PerfExpert mon ex-application en tête)
ET j’offre 10 000 euros & dollars à toute personne qui parviendrait à démontrer que l’une et/ou l’autre de ces deux affirmations n’est pas vraie (bien entendu elle devra me les donner dans le cas inverse!), mais cela devra se faire dans un cadre strict et professionnel que je définis et qui est le suivant (5 points):
- Une équipe TV ou Internet (Française, Anglaise ou Américaine: Wheeler Dealers, CarWow, etc) bénéficiant d’une large audience devra venir filmer les tests et s’engager à publier les résultats, quels qu’ils soient. Cette équipe sera rémunérée après publication des résultats à 50/50 entre la personne relevant mon défi et moi-même, et après acceptation bien sûr par les deux parties de la somme demandée.
- Ce n’est pas seulement une voiture qui sera mesurée, mais trois: une traction, une propulsion, et une intégrale, et toutes en moteur atmosphérique (raison donnée au point suivant): je propose une Honda Civic Type-R EP3, une BMW M3 E46 et une Audi RS4 B7, mais j’accepterai volontiers toute autre proposition.
- Puisque par définition ni PerfectPower ni aucune autre application smartphone ni aucun banc à rouleaux ne mesure une vraie puissance au moteur mais mesure une puissance en dynamique sur route ou sur des rouleaux et cherche ensuite à “remonter” à la puissance moteur par calcul & estimation des différentes pertes (3 types: transmission, pneumatiques, inertie), il faudrait normalement mesurer un moteur seul au banc moteur et le monter ensuite dans la voiture pour les tests, mais c’est hélas beaucoup trop contraignant (surtout avec trois voitures!): la meilleure alternative est de prendre en référence un banc aux moyeux (qui élimine les pertes pneumatiques!) mesurant en régime stabilisé et non en dynamique (pour éliminer les pertes par inertie!), et d’utiliser des voitures à moteur atmosphérique pour évidemment avoir un comportement moteur en dynamique (lors des mesures à PerfectPower & banc à rouleaux & autre application smartphone) le plus proche possible du comportement en régime stabilisé (lors des mesures sur le banc aux moyeux faisant référence), ce qui est parfaitement impossible en moteur turbo!
- Le coût de la location du banc aux moyeux pour ces tests sera partagé à 50/50 entre la personne relevant mon défi et moi-même.
- Pour les DEUX affirmations, le comparatif ne portera pas que sur une simple comparaison des résultats moteur de PerfectPower & banc à rouleaux & autre application smartphone avec ceux obtenus au banc aux moyeux faisant référence, mais aussi sur une analyse de la régularité de ces resultats sur un rapport de boite donné, une comparaison de ces resultats entre eux sur différents rapports de boite (2-3 sur la route et 2-3-4-5 sur le banc), et enfin une analyse de la forme des courbes. Des notes de 1 à 5 seront attribuées pour chacune des quatre parties et le vainqueur sera naturellement celui qui aura le plus de points sur la totalité des quatre parties.
Voilà, ce sont les modalités de base, nul besoin d’en définir d’autres car tout est déjà parfaitement clair, même si bien sûr (ET si mon défi est relevé…) tout cela sera discuté entre les différents protagonistes et résumé sur papier avant les tests eux-mêmes.
De plus et je tiens à le rappeler, tout ceci est purement AMICAL (et il est même possible que certaines conditions soient discutées et revues d’un commun accord…), et ce défi a en fait surtout pour objectf de prouver implicitement que PerfectPower est vraiment une application de mesure de puissance et de performances hors-normes et proprement imbattable, même par des matériels de plusieurs dizaines de milliers d’euros & dollars…
Pour le relever, il suffit tout simplement de me contacter, mais merci de ne le faire que si vous êtes certains de vouloir le faire, de le faire dans un esprit sportif et amical, et enfin de le faire pour les bonnes raisons (information du public… et divertissement entre passionnés!), car une chose est certaine, c’est que je gagnerai ce défi tout simplement car je maîtrise ce domaine mieux que personne au monde, et je veux donc que ce défi ne soit relevé que par des personnes averties qui sont bien dans le même esprit que moi, et si c’est bien le cas, je pourrai décider de leur faire grâce des 10 000 euros & dollars à la fin…
Note: Il est important de comprendre qu’aucun banc à rouleaux ne peut être pris en référence pour un tel comparatif, ce qui serait évidemment beaucoup plus simple à gérer… mais malheureusement, il n’existe PAS dans ce monde de bancs à rouleaux (ni même de bancs aux moyeux d’ailleurs!) capable de donner des résultats moteur 100% justes à tous les coups (pour tous les types de voiture et sur tous les rapports de boite), et tout cela sera expliqué en détail dans un prochain article.
