I absolutely love knowing how much fuel is left in the tank and when I’m ready for another tough effort

Great app! Congrats to the developer. Trying to solve some doubts: 1- Calculate CP and W’ personalized values. In GC---Tools---CP and W’ Estimator. Input your 5’ and 20’ w values (do a test in advance). For example, 5’ @325 and 20’ @291 gives you CP=280, W’=14000. 2- Include CP and W’ in GC. Tools---Options---Athlete Tab---Power Zones tab. Add new (“+” button). Include date, CP and W’. You may also want to include FTP, to simplify typically same as FTP. Below it will appear your calculated power zones (in 7 thresholds). 3- Include CP and W’ in Garmin Device. In Garmin Connect Mobile App, go to More button at the bottom right hand side of the screen. Then Garmin Devices---Select your device (i.e. Edge 520)---IQ Connect Apps---Data Fields---W’Balance. Here you have the app installed and you can manually overwrite default values (250 and 20000) with your own. In the example 280 and 14000. Do this in each of the devices where you have this app installed. You may also want to match the calculation method on how W’ is used and recharged in Garmin and GC, so you get the same figures while riding and when analysing. In Garmin, in the same screen as step 3, set the method to Integer, as suggested by the developer, using Dr. Skiba method. In GC, go to Tools---Options---General Tab---W’Balance formula. In you prefer Froncioni method, set both Garmin and GC to Differential. 4- You may also want to have same power zones in GC (see step 2) and in Garmin. To do so, go to the Garmin Connect Mobile App (not PC, doesn’t work for me at least)---More button---Garmin Devices---Edge 520---User Configuration---Power Zones and manually input the same info as in GC Synchronize and you are done!

I have managed to get a result of negative 30 when doing long hard climbs. On one occasion have even got down to negative 40. Is this correct? - how do i interpret this number? Hope you can help

Hi, like a previous reviewer I am also unable to change the default values. I have amended them in Garmin Express and the SYNC has completed succesfully but it still displays 250watts 20000kj on the device. I am using an EDGE 520 on FW V12.60.

How on earth do you update the W' Value? It displays a default 20000 but Golden Cheetah has be at 31800

Hello I am testing the application, but it does not let me change the default values. Always appear 250 W and 20000 joules. Although you save and synchronize with Garmin Edge 1030 Greeting

Bravo pour cette application ! Un petit soucis cependant mon pourcentage ne revient pas toujours à 100% une fois que j'enregistre mon activité et en relance une autre le lendemain ... Tu sais d'où peux venir le problème ?

Hi. I just tried this today. I noticed that the I didn’t get data for the power graph in my garmin connect. I an using a Garmin 520. Is the developer aware of this? Are there any fix for this? Regards

Great tool. it's cool to see a value corresponding to the pain in my muscles during Vo2max intervalls. It also pushes me further during hard intervalls, cause I see, that there is some power left - against my feeling. It's also cool to see the FTP rising when W'bal gets negative. All in all a cool tool. Thanks :-)

La seul info indispensable lorsque l'on roule avec un capteur de puissance TOP Comme la réactivité du dévellopeur The one and only essential info when riding with a power sensor                                                 TOP                             As the reactivity of the developer

Bonjour, cette application sera t elle bientôt disponible pour l'Edge 1030 ?

Very cool being able to take advanced statistics I normally only look at in GoldenCheetah out on the road.

I love the idea of using this for races. I have an issue with how it works on my 520 though. The values were not going down fast enough. When I compared the Golden Cheetah file, I was down to like 5.4 Kj remaining after a hard climb, where during the ride it displayed like high teens to 20 kj left. I thought I was being weak. I think I loaded the CP and W' data points accurately.

Fonctionne parfaitement et permet de bien se gérer. Au début je le regardais après coup pour confirmer mes impressions et parfois on s'aperçoit qu'on peut en remettre un peu. Attention il faut que ses paramètres soit parfaitement configurer dans GC (que la FTP soit juste est primordial) pour avoir des enfants infos au plus près de la réalité. Good job :-)

après essai en bosse 55km 900m de deniv pas mal du tout je me fixe d arrive a 90% au pied des bosses alors que j étais a 45% du réservoir 10mn avant c est assez bluffant quand on sait bien ce servir du capteur

Work for many devices, have setup formula, full compatible with GoldenCheetah

same comments as another person. Seems like there is a math problem: The calculation in the app deviates from the Golden Cheetah program. The W' expended is less than calculated by GC, and the recharge of W' is to slow.

Absolutely perfect. This is why I purchased the Edge 520. Clear display of remaining W'Bal % in a font as big as any other data field. Thank you.

No issues found installing or configuring v1.1 Still pending to take the Garmin out for a spin to see it in action.
