Cruise

[Robert ferrier]

can radar or dynamic cruise be fitted to 2013 vellfire 3.5 v6?

and also can the cruise control limit be relaxed a little to say like 80 mph?

Pretty expensive to modify to radar cruise control. 

Requires several modules, it was integrated with lane keep assist.

 

Need windscreen camera and the associated loom, the windscreen has a black dot sunscreen pattern that would need to be removed, or glass replaced. 

 

Millimeter wave radar behind grill, control ECU. New cruise control stalk, new clock spring, new dash clocks with the high end integrated screen, electronic brake servo etc. 

 

I actually don't know if it was available on non hybrids. 

 

Cruise control limit v has not been hacked, even across other Toyota vehicles that share components. 

 

Your need a new ECU from a USA Toyota, if you can find one that has matching fueling curves.

 

Alternative is to fit aftermarket throttle controller, these work by fooling the signal entering the ecu

I think it’s more trouble than it’s worth and considering I have cruise control already it’s just lazy. I mean we own cars to drive then don’t we 😁 
i’m usually of the understanding the more gadgets you have the more can go wrong, which is why I didn’t even want electric seats but thank you for your enlightenment😁👍🏼

About the limit, I searched a lot, I contacted some big specialized companies that modify ECU progs in Italy, UK, USA, nothing.
So I bought a PIVOT (Japanese company) cruise control with the plug&play harness for GGH20, and now I'm able to use the cruise control with any speed.

[Robert ferrier]

How much cost and how easy or difficult to do this. Does it interfere with any of the cars operations. Who would be best to install for me?

[R4v3n]

I bought it in April 2022 on Blackhawkjapan, including the electronic module, the brake harness and the special vellfire GGH20 harness (there's a compatibility matrix to find the right harness to buy) for 35000JPY shipping included, which is at the current low JPY rate 215€ or 180£.

 

BTW I just found out I wrote to Pivot support in Japan to be sure to not do any mistake and they were SO fast and gentle to answer, small part of the answer was the exact stuff to buy for my GGH20 : 

product:
3DA-T (similar to 3DA and 3DA-C, so don't make a mistake)
2A harness (connected to accelerator sensor)
BR-1 Brake Harness (connected to brake switch)

Then they sent me the Japanese manual + some pictures with english translation.
It was pretty fast to install, the "hardest" part for me was to find the speed signal cable because my radio got an aftermarket setup, but I took pictures and sent them, and they helped me to the end, until it was working.
 

The product is great, the support is great (Japanese people), so don't hesitate for the price.
 

Don't forget you'll lose the adaptive cruise control (if you have it), but you can always add a small switch to use one or the other.

You forget to mention, the pivot system also has various throttle mapping, so you get a smoother Eco or more aggressive throttle response.

 

Have you used these settings and can say if they make any difference?

Not used at all.
As I use my Vellfire mostly on highways, I just need to set it up to 140km/h (on gauge) or 120 and that's it most of the time.
And when I drive it on countryside roads, I don't care about how I use my gas pedal

 

Last but not least, I run it full E85, and my highest consumption is 14L/100km, which means ~10€/100km, which is still "cheap" for this kind of vehicule !

[Chris.ac]

It's actually pretty amazing, that in the several years of owning the alphard, I've still not found anyone that has managed to remove the cruise or speed limiter.

That's across all the 2gr-fe vehicles. 

I've looked in Russian and Japanese.

[R4v3n]

The maximum speed is flashable (limit to 180km/h), but the cruise control limit is hardcoded in the ECU program.

So you have to dump the ECU memory and try to find in the bin file the memory value which hardcode this speed (with an hexadecimal editor), then modify it and find a way to flash the ECU (which is normally, with Toyota ECU not possible, or not that easy).
I know in the US, frankensteinmotorsport, who is well known for playing with 2GR-FE there (as there's a lot of them) got the memory address for USDM ECUs, but JDM ECU are different for that.
That's why after contacting a lot of companies and flashers (alientech, OVTune, Frankensteinmotorsport,Ivanperformance) I found the Pivot cruise control, which is doing the job perfectly, for a limited cost (as hours of researches with my ECU sent to Alientech for example would have cost a lot more). 

[Chris.ac]

Yep, i think we messaged each other on Facebook about the pivot system back when i found it. 

 

The hard speed limit, it's not that much of a problem, i don't tend to do over 112mph anyway, lol. 

 

The pivot system seems to be the least hassle, and of course you can easily disconnect the whole thing if changing vehicle or selling.

What did you need to do to convert your alphard to run on E85? ... I spend a lot of time driving through France ... would love to get the modification done!

I'm using the eflexplus kit from eflexfuel. It costs 500€ but it's a very nice kit with Ethanol sensor, good quality electronics and an android app for settings, informations etc.

It's easy to mount on the vellfire as you have a lot of room and fuel lines are very accessible.

 

By the way, never go from 100% unleaded (do you name regular gasoline as unleaded in UK as well as in the US ?) to 100% E85 in one shot. Unleaded make deposits in the cylinder, which will be cleaned by the E85, but if you doing it in a single shot, you have a risk to make it go down on the piston rings.

So do it like 25% first shot, 50%, 75% then 100% all the time.

ok interesting ... you can't get E85 in the UK at all ... but I keep seeing the price when im driving through France ... might not be worth it if I can't just refill with E85 when i land

 

Will have a chat with my mechanic though ... car is off for the annual service in a couple of weeks

If you can't buy E85 in the UK, don't bother buying a kit, it doesn't worth it at all.

What you can do to lower the bill is to mix SP95-E10 & E85, respectively doing 50/50. On any Toyota, the map is rich enough to have no problem at all to compensate (you can check you STFT and LTFT if you want to follow the evolution of corrected injection).

Just a reference note, my 2008 3.5L AWD Vellfire VL has factory radar cruise, so was possible option on non-hybrids
