Title: VCU Wants - DIY Maintenance Mode
Post by: PWM on August 25, 2020, 09:12:04 PM
This thread may seem dumb to some and lazy-ass to others but it really represents a non-invasive alternative to hacking tools I have in the works...rethinking, why.

My wants are minimal.

1) Brake Bleed Assist - utilize ABS modulator to purge fluid.
2) Chain Clean Assist - w/ bike on rear stand, spin chain on a revolution-per-minute creep speed.

Be interesting to know what the cruise-activation minimum speed setting is possible today to mimic #2?

3) I forgot what the third item was, but if anyone has input I can forward a formal request to Stephano @ Energica on our behalf.

Of note - One would fully expect to have a waiver of liability integrated into any DIY mode given the perceived hazards and this will be encouraged.  Tesla can do it - so can Energica if the purpose is there. 

Help me w/ #3.

I have put the bike into park assist or reverse while on rear spools before for chain lubing. Works fine. I don't feel the need for an additional mode for that.

That's cool!

So, one-hand on the throttle or do you invoke the cruise control?  Very interested in how slow it will go. 

Intent on my part is to simplify a chain clean/lube/drip process to set-n-forget slow overnight thing. 

Then do whatever for quick wipe then add water repellent wax...using park assist speed as mentioned.

One hand on the throttle. Park assist is like 2 mph max.

Understood.  Maybe a throttle stop screw is all it would take for a steady-state creep speed then, but the non-invasiveness is lost...thanks for the input.

#1 A front brake flush takes 5-10 min, the abs pump would not make this process faster or easier.

#2 - Put your bike into slow forward mode. Use a large ziptie around your throttle and brake lever to act as a "throttle lock" to adjust the rotating speed of the rear wheel.
^ I use this to spray chains with cleaning solution and also lube.

Keep your fingers the hell away from the sprockets. Your soft bits stand no chance...


I believe CC has a 25mph min speed.

A short bungee would work as a throttle-lock, too.

I even have photos to prove why it's a bad idea...

Agreed on brake bleed is a nothing burger.

Still not convinced on cave-man ways to setup creep speed that needs to be very slow to be intrinsically safe, e.g. set-n-walkaway...but more importantly the process requires time for optimal efficient and copacetic results (it's proven).

Demoni - I realize now it is best to shit-CAN the UDS service-ID approach because of the proprietary hoops, can you confirm if the traction drive's serial programming port is empty and plug capable?  The RineHart folks are a stone's throw from me and I'm confident on the application support to command a speed reference (jog parameter) once the power is enabled to the drive.

Be soooo simple to establish a UI approach if only others saw the utility...<sigh>.

A video might show the process clearer...

^ the copper piece is a 3d printed "parking brake" a EVA owner gave me.

I respect a software based solution. However when a simple physical solution already exists that reaches the same goal I don't see the benefit.
