My cruise control did not react fast enough. When I would go up a hill or pass a semi, the box would slow down and then speed back up gradually. I called Rosta and got the switch positions to make it react quicker and it has made a big difference.
If you open the black box that the cable comes out of,(#10 torx) you will see a series of micro switches numbered 1 thru 12. You only have to adjust the first two, Leave The Rest Of Them ALONE!!! If switch 1 and 2 are down (default position) That is the least sensitive. 1 up and 2 down are more sensitive, 1 down and 2 up is where I have mine, and 1 up and 2 up is the most sensitive, which you probably don't want. Give it a try and report back!!

Great to know. I'll take a look at mine at lunch :)

Very Nice ....

I may have had a problem and may have fixed it...in any case...you have done a very nice thing.

I'll check in the warmth of my garage when I get home tonight....about ZERO wind chill today in Washington DC...and I printed out your SHARED SPECS for switched 1 and 2.

Love my RF switch...by the way...topside of the wheel to match up with my right hand in the 2 o'clock position...just trigger with the thumb without moving the hand....or looking.

Many thanks..................

I just want to thank Davex for posting this tech bit. I opened my cruise and changed the dip switches like he did and it made it a whole new beast. I have never been satisfied before this with the cruise because it was so sluggish. Works GREAT now.
thanks
upshift..

I thought this would be good information, You're Welcome!

Wow...and I knew there had to be some sort of adjustment for the sluggish cruise....Thanks for the info :)

good job you know there is a recall in the works on that and if you want to adjust it the ajdustment is right next to the throttle body.

I took a brief look at mine and didn't see the torx bolts.Do I need to take it out of the bracket? I installed the cruise myself and just don't remember seeing those bolts. Thanks

Yes, blimey you have to remove the two 10mm bolts on the top and turn it over. You will probably see a sticker that says not to remove the cover.

ifeldwn, You are talking about a different adjustment for a different problem.

Thanks,I just wanted to confirm.I remember the sticker.

Sweet -- I thought mine was just installed improperly. Gonna try this!

I nominate this for post of the year - you rock :bow:

I had to void the warranty on my Rostra (dealer paid for it to be installed at an authorized shop) but it was well worth it. In the default position this cruise was as bad as the OEM model in my old 80's Pontoon 6000 company car. You set it for 60 and go 55 up the hills and 65 down them. The potential warranty void was worth it, since the cruise was about useless as installed.

In my car the Rosta is mounted "upside down" - the panel with the torx screws is on the bottom. I disconnected the wiring harness - pop off the orange retaining clip then pull the connector out. Then take out the 2 10mm bolts holding it to the bracket. Slit the "warranty void" label (either one) and remove the 4 torx screws to get at the dip switches.

The switches are labelled 1-12 -left to right.

To make the switch settings clearer it is binary:

Switch 2 Switch 1 Value Setting
-----------------------------------------
Off Off 0 Least sensitive (default)
Off On 1 More sensitive
On Off 2 Even more sensitive
On On 3 Most sensitive


Like DavesX mine was on 0, the default, and I changed it to 2. Now if I set it at 60 it may drop to 59 going up a hill and hit 61 doing down. Much, much better. For kicks, I may try the 3 "most sensitive" setting to see if it locks it on 60 exactly.

Remember, the lower the setting the greater the speed variation but also the greater the potential MPGs. The higher the setting the lower the speed variations but also lower MPGs.

Thanks DavesX!

Def. gonna try this. To this point I had been just kicking it out of overdrive before the "climb". Now I won't have to thanks much. You def. rock!!!
Just a question...? Are they actually labled 1-12 so I don't adjust #11 instead of #2? I'm gonna leave #1 alone and adjust 2 to the up position. Thanks.

They are clearly labelled 1-12, you should have no problems. Just make sure you have that stupid T10 torx handy, I got it out of the bracket and then could not find the stupid torx bit. Finally did, then dropped the bit down into the car! I finally found that and fished it out :relief: and got the change finished. I ordered a couple of cheap torx screwdrivers from Amazon the next day, a lot easier to find than the stupid bit.

Why not be brave and go for 3 with both on? Then you can report back how it does - I would predict it would be rock steady on the set speed and not have the +-1mph I see with it set to 2. Once you have changed it you will see how easy it is and can change it back.

Depending on how much slack was left in the harness on your install, you may can get the cover off and switches changed w/o disconnecting the wiring which would save you some time.

Completed the mod. It took maybe 10 minutes. Sure enough it holds the speed way better now! Thanks for this info very much!!!!
Only problem was the O-ring wanted to pop out. Just make sure it's in the slot before putting plate back in place so it doesn't get cut. Thanks!

how did I miss this for 6 months????

I can't wait to try it, hope it solves the slow/fast problem.

I can't wait to try it, hope it solves the slow/fast problem.It's so easy. It will solve the problem. I've been dealing with this for 3 years. Is so much nicer!
I'd like to know why it wasn't set like that from the factory??? :eyebrow:

That is a good question, makes you wonder if they did any real world testing on the units before selling them?

They were prolly set up for the echos. That would account for the inaccuracies.

^^I believe you are correct sir!

Great info. Will have to try this, as I have been dealing with the current settings for over 2 years. Great tech post. Thanks.

got mine done and it make a big diff!! Thanks for the info.

Major props to DavesX for figuring out this debunkle. I thought I was doomed forever with this problem. Got it fixed just in time for heading up to the Indy VIP.

No doubt! On the way into work this morning it even worked like a champ up the big hill!! I couldn't believe it, I will be using the cruise a lot more.

Thank you DavesX! I am new to this forum (today) but have been scouring it for hours. Yours is the first fix I have seen that I wanted to try. I too have been putting up with a lousy cruise control for a year and a half.

I went out to the garage at 9:45 in the evening and did exactly what you said, took about 7 minutes. I'll be trying it out on my morning drive to work.

Thanks again!!!

Another happy customer! Thanks to DavesX

Ok, sure enough the cruise worked much better this morning on my way to work. I may open it up and try the 1 and 2 switch up position just for S&Giggles.

Thanks again for the post.

Did mine last night drove it today with both switches up it stays at the speed u set it really well :bow: thanks for this great info i hated the way my cruise control was but way better now. :clap:

Mine was on it when I bought it so I'm not even sure who's model it is. But anyway, where is this box located? Mine does this and I HATE IT!!!

next to the drivers side strut tower.

Naturally, that ain't my model.

Anybody have a similar solution for it?

Great Post. Thank you!- Always wanted to get cruise to work right - never spent the time.
Now I actually like using my cruise control.
One suggestion - change Automatic tranny fluid to Synthetic Amsoil - much smoother shifts - and yes it is approved. Working great for 4000 miles on myXB.

One suggestion - change Automatic tranny fluid to Synthetic Amsoil - much smoother shifts - and yes it is approved. Working great for 4000 miles on myXB.Really? Who changed the fluid for you? I thought the little xb already shifted pretty smoothly. What is the approx cost for the change with Amsoil?

Easy to change - if you search there is a post some where.
Just unscrew hex plug from case(want to say it is10mm) underneath your XB - do not need to remove pan and gasket. Takes a little less than a gallon - approximately $35.00. I plan on doing this every 20-25,000 miles. Go to Amsoil .com.
If you pay $10 you can become a preffered customer and it is $26.55 plus shipping. (I use their synthetic oil too).
My tranny would shift hard - especially under a load. I also tow a trailer, and also on some shifts when my cruise was activated I noticed it.
The shifts are much smoother - one of the best things I have done to my XB and other vehicles I have owned.

Thanks.

Here is a link to the tranny fluid on Amsoil site:

http://www.amsoil.com/storefront/atf.aspx

Purchase a gallon - and will have some extra.

This does not replace ALL the fluid - need to drop pan - from what I have been told Toyota says you do not have drop pan and clean filter till close to 200,000 miles - however I plan to change fluid every 20,000 - 25,000 miles - easy enough - and after a couple of changes should be all synthetic.
I may drop pan earlier - but I figure I'll take my chances against dropping the pan, and just keep changing the fluid.

this is some sweet info i just had mine installed and thought something was wrong with it.

Does adjusting the C.C. switches help with the following:

My CC seems to hold speed okay. but when driving and setting the CC speed, it wants to lose at least 5mph when I take my right foot off before it kicks on and gets me back up to where I set it at. Meanwhile traffic closes fast from behind.

(I have a 5-spd)

^^^Yes mine used to do that prior to the adjustment. Now it engages right away and stays where you set it. I still have a problem occasionally when you have to hit the set button a second time cause it didn't register the first time.

Man, I should have found this months ago. I've been vexed with crappy cruise performance since the day I drove it off the lot... slows down 5mph as soon as you set it and may or may not speed up and bogging way down going up a hill then WOT over the top ending up 5 - 10mph over what you set it at. Now do I want to brave the 17 degree weather here or wait a few days?

Be brave and try the

On On 3 Most sensitive

position and let us know how it goes. I have mine in the 2 (next most sensitive) and it works tons better that it was after install, but I have been tempted to try the "3" and see how that does. Mine does get a little behind on hills compared to other cruises I have used.

Does anyone know if this will work on the tC too? And could you post a pic of the box that you have to pop open, so I could share this with everyone?

Thanks

ThanksIt might as long as it's a Rostra unit. Worst case you just set it back to normal.
