Any Power Steering changes/improvements on 2016+ Spyders?

[Sunder]

I was told by someone that there were some power steering improvements on the 2016 model (and newer).
I am looking at the 2014 model (and newer) because of the 1330 engine, but was curious if there was any truth to other significant changes that occurred in 2016?

Thanks in advance!

Well I have a 14 RT .... and I am 75 yrs.old .... I have NO issues with steering it , nor just turning it on my gravel driveway. I mean if some one wants to drive something with little to no Soul :dontknow::dontknow::dontknow:... Un-like the vast majority of veh's out there, driving a Spyder should be a bit of a challenge. ... Two wheel Mtc's are easy to turn when operating above 10 mph .... but slow down and they will tip over easily.... ever pick up a GW :gaah: ..... good luck ... Mike :thumbup:

The "power steering's" effort diminishes as speed increases. Maximizes as speed decreases.

There was a major power steering change around the 2018 model year...

2016 RTL Power Steering

....Not sure how much or little effort is going to be assisted while trying to steer. My understanding is that the PS asstist is mostly at stop to moving 1 to 2 mph.

Anyhow that's when I get the full effect.
As others have said 'slow and most asstist'.
Faster and no asstist.
That's the way for my 2016 Spyder RTL.

Everything has it's limitations. ......:thumbup:

Retrofit 2018 DPS into earler years

Hey Sunder -- here's your summer project: investigate what needs to be done to retrofit the 2018 DPS into earlier RTs and F3s.

If you keep it under $500 I'm willing to be bleeding edge.

I just looked at cheapcycleparts ..... power steering unit part # 709402437 ...$ 1469.99 ...if you do the labor !!!!!..... Mike :thumbup:

If only it was that simple

Mike -- it appears the DPS changed across model years. Started with p/n 709401220 in 2014 then replaced with p/n 709401564 through 2017.

But starting in 2018 it looks like p/n 709402437 would not be backwards compatible because it uses a single 10-pin connector for power and control. Otherwise I'd be tempted by the new one on eBay for $600 whose label says EPS High Torque-SAS.

And there's a used p/n 709402050 (date sticker 2017/03/13) for a 2017 F3 which OEM Parts notes "Date Aug 1rst 2016 And Up" and is replaced with p/n 709402437! Its label says Spyder High Torque.

So it looks like the old-new difference is High Torque with 10-pin connector.

I don't mind adapting to a 10-pin connector but I'm concerned about firmware changes. Didn't BUDS2 come out about the same time?

Bert ..... YOU referenced " 2018 DPS " so THAT was what I looked for , mostly to find the COST ..... bad info IN bad info OUT .... it's that simple ..... Mike :thumbup:

It's complicated

Mike -- look for p/n. Here's the $600 new-in-box DPS https://www.ebay.com/itm/363513219301

So what's the difference between the pre-2018 709401220/709401564 and the High Torque 709402050/709402437?

You can gain torque with more power input or by changing the gear ratio.

Based on the small pin size of the 10-pin connector, I expect BRP/Kongsberg chose gear ratio. That is, they spin the motor faster to provide PWM-controlled steering assistance.

After chasing through parts catalogs, I believe the HT DPS integrates the Steering Angle that was separate on the pre-2018 DPS (I'm not having any luck finding a separate Steering Torque sensor so that might be pre-2014).

Mechanically and electrically I think the HT DPS can be retrofitted with some work into pre-2018 Spyders. But I have my doubts about BUDS communicating with the DPS for steering angle and torque centering.

Any thoughts?

" thoughts " ..... not really , this is what I believe to be above my " pay grade ". .... my input was solely directed at the Price I found ...... Mike :thumbup:
