From one of the reviewers : ".. however there is an average 5% additional drop in charge in a 100 mile trip due to turbulence." So limiting the air flow through a rim is known to decrease wheel drag. I don't want to give up 5% on long trips as it makes a difference as the R1 is a large, not...

Might get. How hard are they to remove? I'm guessing hard. Ask because I like the look around town w/o the stock areo so can see the yellow brakes. But put the areo back on for long trips. Can see getting this cap off as hard /impossible as the areo blades put the existing ones on it free.

Are we sure the stock ACC cruise doesn't use regen when slowing under radar control. The brake pedal moves a bit sure, but the the center screen shows regen in the wheels. AND the effiency graph will show a positive spike in effeciency on a hard brake or long down hill brake. The general...

For anyone looking for info on different drive models, the l best site with summaries I've found is run by Gerry! Maybe everyone knew this but me, but thecommaspce.com is the only place that I've found that describes what groups of models were designed for and what there reputation is for real...

So installed and got TR16v2. Seems to wander on road more than Open Pilot. Don't know how to find what model Open Pilot is running (google failed me). I changed back to TR15. While loading, it looked like it took some cached data and did some training? Was surprised. Should I clear the data...

With out the second harness, does the Sunny system have access to the blind spot monitors? If not, I would think I would do lane changes as with Open Pilot ( turn signal and a Nudge). If Sunny does get the monitors, this is SO cool. Also, just found an ABOUT that has good data on Sunny. It...

At work (boo) and can't download now, but how do the models work? Can you 'change on the fly'? Also, are there any specific options in Sunny a Rivian should turn on, like Turn Off With Brake . Others?

THANKS! One more question, looks like in Sunny Pilot you can choose which driving model to use (CRT, TR15, DTRv4, v5, etc). Coming from Open pilot where there appears to be just THE ONE model, what model works with Rivian for 2 lane, 60 MPH cruising?

If this is stupid, please be gentle, I've read all of this thread and been on Discord (what a mess) but now that the Rivian MADS is merged into the 'master developer branch' of Sunny Pilot(from Comma Space, 5-24-2025), what exactly is the sunny branch that people are running? I know there was...

Be careful with the Delta Pro 3 and Rivian. I used a 2/3 prong adapter so had no ground loop. House connected at 240VAC to DP3 so powers well pump and other essential things. When house powers up, draws 2000+ watts and I erroneously didn't turn off nonessential for this test. When plugged 120...

This is no longer available, as I bought and am enjoying it on my R1S right now.

Website says USA orders disabled because of tariffs right now. That sucks!

The reason is when you are on high, the angle on the front drive shafts increases and the torque become harmful it the Constant Velocity joints (CV joints). Lower is better for high power transmission. Rivian protects the shafts by limiting speed.
