TQ motor

[AntonioAlfaro]

Antonio, regards. I look forward to your perception of the functional/performance aspects of the TQ Ammersee update, as much from your subjective sense, as data based.
Meanwhile... after a year of riding I'm curious as to what tuning settings you are currently using. I had settled on E 100W/100%, M 150W/150%, H 300W/200% as being as good as any, but thinking over how to best utilize my limited capabilities (100W sustainable, 150W for 1-2 minutes intense effort) I'll try boosting M to 200W/200% to better tackle 5-10% grades, reserving H for intense efforts on short 10-15% grades.
Best Rob

Hello Rob,
The following are my settings that I have been using for almost a year and keep unchanged with the new software.
They are based on my FTP of 150 W and my weight of 56Kg.
ECO 75W max, 112% assistance, 70% pedal response.
MID 105W max, 112% assist, 70% pedal response.
HIGH 138W max, 200% assist, 90% pedal response. (Never used, never tested).
Greetings

I'm as surprised as I was back then at your minimal 75-105W use of motor assistance. We're on opposite ends of the spectrum, and your 56Kg compared to my 77Kg doesn't explain it. Wondering what your rides are like: typical speeds on the flats and your corresponding power input, and incline grades and your power input.

Input from other riders willing to share their motor tuning settings would be very interesting and welcome.

Hello Rob, I hope not to bore you with the following data and that they are rather useful for you. Absolutely all my rides on the Domane+ SLR with TQ propulsion have been recorded. From these GPX files and with the help of some functions that I have created in Python for my analysis and projections supported by AI, I have a huge database that describes my performance and that of my bike for the assistance configuration and the different ranges of slopes that I have defined for my environment.
To provide a timely response, I have randomly taken a sample of 37 rides. The results are as follows:

My cyclist average power as per % slope

Number of seconds in each Ebike Mode for the total of the 37 rides

Finally, a percentage breakdown of time spent in each Ebike mode for each range of slopes.

As you can see, I almost always have Mode 1 activated, as a habit.

Apologize for the informal presentation of these results, but the purpose is to give you a general overview of my personal data. Regards

 

[rdv]

Apologies for boring everyone else on this thread.

“...informal... overview”? More than enough ...almost .

Distilling... your average rider power input falls into a consistent range of 100-125W. Adding that to the motor's 105W suggests that on average you are climbing 9-11% and 11+%grades with 230 total watts (rarely, 263W). Is there significant variation relative to the average in the course of a particular climb? Curious as to how a sample steep climb of yours works out: length, grade, minutes, speed, max total power.

I seem to need at least 100W more on average, and have reached combined totals of over 400W in short bursts up 11-15%. Maybe our weight difference means more than I surmised.

Again, would greatly welcome input from others as to motor tuning settings and personal experience with 'light' motors.

Buenos días: Desde octubre de 2023, tengo una Trek Domane + SLR7 con el motor TQ. Desde la llegada de las altas temperaturas, la pantalla de control muestra el código de error 5401. Ha estado fallando de forma intermitente, hasta hace 2 semanas cuando la asistencia dejó de funcionar.
Apagaba y encendía repetídamente y, a veces, se solucionó. Si la apaga un buen rato en un descenso, se enfriaba y todo volvía a trabajar. Al parecer, es un fallo conocido por TQ y van a proceder a sustituir el display que, evidentemente, se encuentra en garantía. Ya llevo 10 días con la bici en el taller TREK esperando la pieza.

¿Cómo puedo cambiar el nombre que sale bajo mi foto?

 

[Captain Slow]

Antonio that's a lot of data to wade through. Could you please provide your thoughts about your experiences riding the bike with a TQ motor and maybe tie in the data a bit?

All - it has been a minute since I've been here last, but have (so far) around 4,700 miles on my TREK Domane+ SLR 7 - I just recently (end of August) took it past my local TREK shop to get the firmware updated. That process went smoothly, but was done just a few days (3 or 4) before the new battery firmware was released. This firmware is supposed to speed up battery charging time by ~30%.

Having been a mechanic in bike shops for 30+ years to support my habit, I want to do my own maintenance - including any software updates (I've been programming Di2 for 10+ years now) so I dug into what I needed to do to get the needed connector and access to update firmware myself. I've also since purchased a TREK Fuel EXe (which also uses the same TQ system) - so, when my adapter arrived today, I dove into the process of updating both bikes. The MTB (the Fuel EXe) when without a hitch, it hadn't had any updates yet (the tool shows all previous update history) and all firmware now matches the published latest versions. Then I went to update the Domane+... "No updates needed"... um, I can see the battery firmware isn't the one released on 2 Sept, so I'm a bit befuddled.

Has anyone come across any issues with the system not recognizing that new firmware is available. I'm going to dig around a bit more to see what I can find, maybe some method to force a reset of the bike computer (maybe let the battery completely run out, or some "ctrl-alt-delete" reboot type procedure) to see if that does the trick.

One other oddity - the Domane+ (all good except the battery firmware) DOES show current firmware info via the TQ app "about bike" page; but the Fuel EXe (all firmware updated) still shows "n/a" for all firmware - just like the app did for the road bike before it got its update at the end of August. The TQ page does say that the latest firmware is needed to push firmware updates to the app.

Thanks in advance for any suggestions.

Hello WillShootPhotos
. TQH has recently announced an improvement in the firmware that will be released in the middle of this month, as well as an improvement in its application. My recommendation and following the best practices in managing updates is to give a reasonable amount of time before upgrading. Although the new release has been tested in the laboratory, it is the massive use and under various conditions that gives it validity. Waiting is better than sorry. Greetings

Will, Antonio,
thanks for posting and helping other TQers catch up some.

How are you guys learning about latest firmware updates? I hadn't heard anything since the boldly announced, very disappointing Ammersee update. My TQ app still shows N/As, still no way to get current versions on my own.

TQ is behind the curve when it comes to firmware updates and support, making it mysterious, difficult, and keeping it behind the dealer wall.

What might be coming?

RDV,

I use this page for the latest updates:

Release Notes

Release Notes for the TQ-HPR50 E-Bike System. View updates now!

www.tq-ebike.com

It doesn't have "notes" for all the updates, but does show the current versions for all the various components within the TQ system. They did "pre" announce the battery update on this page, it appeared in mid to late August with the September 2, 2024 date you see on the page.

The various firmware info for each component will remain "N/A" within the TQ app (this doesn't show in the TREK ebike app - you have to use TQ's app) until you get whichever update actually enabled the transmission of the info. So, updating your bike to the latest firmware will enable those items to display. Tho, I have found it took a few connections before one of my bikes showed the versions... I think there are a few back and forths between the app and the bike as it wakes up as the TQ app sometimes shows no data for 30 seconds or so until (I guess) it has had its requisite cup of coffee and is ready to face the day ahead...

I sort of "get" why TQ is keeping the dealer in the loop on this. While it makes sense to try to release all functionalities to the consumer themselves; not all consumers (no offense) are as savvy as others, and without spending extra time (read as extra $$) it is more difficult to cover all the permutations and combinations of how one might interact with software/dongles/procedures to (for lack of a better term) save the consumer from themselves. It can be difficult enough to get a trained bike shop staff to follow basic procedures... At the same time, being a computer geek by trade and having worked in shops off and on for 30+ years to support my habit - I wanted to be able to do the work myself.

As for what might be coming - I'm not exactly sure... with the product now somewhat "mature" (we're, I think, 2 years into this motor/battery setup) most of the main functionality (send firmware info to app, etc) and primary improvements (such as the battery charging time improvement) etc - may already be behind us. I'd guess most things are tweaks for efficiency, resolving (hopefully) minor outlying issues, etc.

The one thing that (as a geek) might be of interest would be to improve upon the range info that is part of the TREK TQ app - where you can see (on the map) the distance they think you can travel (they say it takes into account the wind, weather, road gradients, etc); perhaps if they could flip it around and let you choose a route and then it adjusts your settings to ensure you can make it that far... maybe introduce some AI tech into the process to improve outcomes, etc - but who knows... I'm just in brainstorming slash wishlist mode at this point.

Antonio,

Good info - I'd not seen anything about another upcoming firmware release, but I'm still trying to sort out the best locations for such information. Where did you see this?

As for when to apply updates, etc - again, good thoughts... I'm in the tech industry and we sometimes don't call it being on the "leading edge" but call it the "bleeding edge" because you can incur the pains of testing the software/firmware out for the company.

I tend to give things a few weeks (at a minimum) before I do the update, but with this one being somewhat significant (improved charging speed and better mgt of the system as the battery gets low) I figured it was worth a shot. So far, zero issues after 1 ride on each bike (Domane+ SLR and Fuel EXe)... tho neither was drained too low. I do shorter MTB rides and have only seen my battery get down to say 70% charge left (I lean into the "support" side of things rather than the "make this a mini e-motorcycle" approach - all good however anyone uses eBikes, this is just my approach); I did push things a bit on the road bike yesterday and saw it down to about 25%, but didn't see any big difference in performance.

I've only tested the battery down to completely empty once, and I did notice a pull back on max output/support once it got below 10% charge - but I've not seen any sort of "this is what the system is designed to do when the battery gets low" information either. If anyone has seen that somewhere, can you link me to that source?

I'll keep my eyes peeled for upcoming firmware releases...

- Will

Will, thank you for the informative response.

I had managed to find my way to the TQ support page after posting, duh! I did see the Sept 2 update, a welcome improvement for the community, particularly the low level boost, though the battery has not been an issue for me. I rely on the % charge remaining (rather than the range, which fluctuates with the terrain) and seldom drop below 20% (drained it only once). The % metric has been dependable, though I haven't tested whether that last 20% depletes at the same predictable rate.

Antonio might have succeeded in befriending someone at TQ and gotten a heads up regarding amid-September update. Communication not having been one of TQ's strengths, let's hope they take a comprehensive and informative approach, and possibly address some complaints/requests posted in this and similar forums.

Best, Rob

I don't use the integration with the TREK app for my rides either - I too keep an eye on the remaining percentage, sort of use the "time remaining" as well. I'm not trying to either max out the battery support for the fastest possible rides; nor am I trying to do a century (knocked out plenty of those in my past before some health issues cropped up). I just use some of the support to keep my in with my friends and (as I joke with them) try to use the motor for good and not for eee-villle... LOL I was more positing on what the future may hold (I am an analyst/geek by trade).

Ahhh... on the info source front... Since I do a bit of side work repairing bikes for friends as a bit of a side hack - I registered w/ TQ as a "repair shop" so I do have access to the updates, but am only recently signed on, so I'm not sure how proactive their communications w/ "Dealers/shops" are.

Will,
I came across an article that broaches 'what might be coming' from TQ (from a few posts back) that you might find interesting. Its focus is on eMTBs, but some of it would likely carry over to eRoad bikes.
https://flowmountainbike.com/features/the-future-of-emtb/
Do let us know if any word of an update or any other news pops up on your 'Dealers/Shops' portal.
Regards, Rob

Thanks Rob! I will do... and now that I've one of each (I just picked up a TREK Fuel EXe 8 to pair nicely with my Domane+), the MTB news is good info for me too!

Curious as to TQ HPR50 Practical Peak Power

While I understand the concept of peak power, it's practical utility still eludes me.

My understanding is that the HPR50 can produce a peak output of 300W, but sustain only 250W on a continuous basis. The output is programmed to be automatically curtailed at some point to protect the motor from overheating and damage. My interest is in learning, from anyone who has experienced it firsthand, what combination of conditions led to the curtailment: duration(minutes? seconds??), speed, grade steepness, or … that would provide some insight as to what the peak 50W actually delivers.

Thanks in advance, Rob.
