LS3 Cruise Control

[NCFJ]

So if the person who is doing the swap knows perhaps ask them?

I wasn't having a go, just suggesting if you're paying someone to do a job they should know to do simple things like cruise control.

I don't mind helping people who are attempting work themselves, but it's a bit annoying effectively helping someone who is being paid to do a job (I mean we give you the answer, so you tell the mechanic who then gets paid for being given the answer. He should research this on his own time).

Anyway the answers above should give you a pretty good idea

I am the person doing the swap. I have researched the subject, obviously you have not because until recently no one had a simple solution. Hacking something together like CC from a bunch of different vehicles etc is not something I do on my own vehicles let alone a custom vehicle for a customer. Currently, Dakota Digital has a set up that might work, I am no where near ready to install so it is not all that high on my priority list to call them and narrow down a final answer.

In regard to your logic of not helping a guy that is just going to relay the information to a mechanic that is going to do the install, YOU SIR ARE A PUTZ!!! I have helped more people doing swaps over the years than you can imagine. The information I give out is commonly refereed to as work product. I GIVE it away freely. Sometimes it is better to remain quiet and be thought a buffoon rather than open your mouth (type) and remove all doubt.

Everyone else please excuse my rant.

Well you know me.......... WOOHOO!

S,

Sent you a PM with the new cruise control kit I'll be using.

1. Get truck to up 65mph.
2. Measure distance between accelerator pedal and seat base.
3. Cut broomstick to same length.

If you check eBay or junk yards, you can source a DBW cruise module from any GM pickup. Probably less than $30. Make sure you get the pigtail.

It will mount right on the firewall, same place it does on a pickup—right by the drivers side hood hinge

Then call ROSTRA and they can direct you to the right stalk and brake switch and how to wire it to the cruise unit you get. I did have to add a relay as directed by rostra, which they provided, and all functions work flawlessly. It set me back under $100 for everything on my DBCable, so I can’t imaging DBW would be any more.

I used Switch part no 250-3743.

Excellent advice. I have a 28 year old Rostra unit with stalk that looks perfectly like factory would look on a 60/62 column. It has a sensor in line with the speedo. That sensor does eventually fail. I'm on my third. But solutions can be found, and Rostra seems to be good at it.

I second the comments and philosophy of tapping the site for solutions that I pass on to the shop that has little experience with the 60 series. I am fortunate to have a shop that is extremely friendly to that process. They want to serve me, but don't have the time to dig up solutions. I help dig up solutions...and they implement. Totally legitimate process for us all. I would also have no problem with my shop researching the site to find solutions for me. The age of our vehicles makes that unlikely, though. So I adapt to help with the process.

65? It's not an f series engine anymore. You don't want to get caught with an inadequately lengthed broomstick

Adjustable length broom stick. High tech swaps demand high tech solutions

You would be one of the few shops who gives back to the community.

2 years ago I wanted to fit a TR6060 gearbox into a 3 generation commodore (Pontiac GTO). Everyone said it couldn’t be done, wouldn’t line up, required too much custom work. I went ahead and did it anyway, figuring out exactly what needed to be done, what parts to use and how to do it. I posted up a detailed guide on a forum for other members’ benefit… There are now 3 workshops here in Australia using that information to provide drive in, drive out packages. They’ve never donated a single dollar to the forum, never given me credit for the design.

Last year I converted my L98 based commodore to run on LPG. Rather than using the tune in the LPG computer (which has to adapt and react to the factory ECU) I wanted to use the secondary tune table (normally for E85) in the E38 controller for LPG… Again people said it couldn’t be done. I designed a circuit/controller which converted a signal from the LPG controller to trick the ECU into switching to the secondary table. The result was 433rwhp on petrol, 430rwhp on LPG (Far higher than normal). Again I posted schematics on how to build the required module. There are now at least 2 shops I am aware of using that design in LPG conversions. Again, not a single dollar donated to the forum or any credit given.

So you can understand why I am a little over doing the hard yards of designing solutions, posting the information to help fellow car enthusiasts only to end up having someone else profit off my hard work without ever giving back to the community.

I would estimate at least 80% of business operate in this method… They have a vested interest in keeping knowledge to themselves so people have no choice but to pay them to do the work.

So when the OP asks how to make cruise control work so he can give the answer to a workshop (who he never mentioned or said was a sponsor of this forum) you can understand my reluctance.

Cheers

EDIT - And as for the answer, if the OP can provide some information on exactly which ECU he is using and whether its using software like EFI Live or HP Tuners we can provide a more detailed answer. On some of the ECU controllers the cruise control is wired directly (not using a BCM), meaning you can reverse engineer the wiring schematic and either fit a cruise stalk with the correct wiring polarity, use a stalk which fits the steering column style and use either relays/transistors to swap the wiring polarity or potentially a Arduino module or physical buttons on the dash (although i find these less user friendly).

As an example of the wiring...

Again its much easier if the OP is tuning the LS3 using EFI Live or HP tuners as its possible in the tune to program direct inputs (using spare pins) to activate cruise control. That reduces the need for either a BCM or expensive adapter boxes (which basically convert physical signals from the stalk into CANBUS data packets which is what most of the modern ECUs use).

My build is listed in my signature. It was clear from the start who was doing the work and that it's still in progress.

I have a Masters in Mathematics from a top school. I like to think about problems & solutions. I DID NOT ask the question so I could relay it to the shop (Stan didn't even know I made the post). I asked because I have a genuine interest in Land Cruisers. I had a few spare minutes, was researching the topic and thought I'd ask the enthusiasts here what solutions they came up with in the past.

While there are a lot of smart people on this forum, none of the solutions related to these trucks require a PhD in physics to solve. ALL can be sorted out by an astute, analytical individual. However, relying on those with experience saves time, mistakes and often provides elegant solutions.

For clarity, my goal is simply to learn more about these fantastic vehicles not to poach information for personal gain. I am appreciative and respectful of the knowledge shared on this forum.

 

[Feistl]

I view ih8mud on my phone... it doesn't show signatures... so I had no idea what the build was or who was doing it.

Literally just someone asking for help with cruise control who is getting a workshop (which was unnamed) to do the conversion.

 

[Cruiserhead05]

Unearthing an old thread.

Did some searching and aside from the DBW mention, is anyone having luck with cruise control other than Dakota Digital (DD)?

My LS swap (80 series) has been running DD for ~20k miles without issue but recently started acting up (it would go dead). Swapped in a new unit and problem got worse. Pedal would engage without having foot on the gas. Remove DD and problem is gone so I'm not eager to try a third DD unit.

Wanted to check in here and see if anyone has successfully been using a third option.

What engine/transmission/PCM do you have?
What did DD say?

 

[Cruiserhead05]

L99, 6l80e, factory PCM (engine, tranny and pcm was pulled together from 2011 camaro).

DD just wants us to try a third unit but figured I'd check here and see if folks were using a different route.

I think on most Gen 4 motors the Cruise stuff and the brake input is in the BCM. When i was researching gen4 vs gen3 for my swap i came across bp automotive talking about if you use an E67 ECM Im pretty sure you can wire up cruise and have it controlled by the factory ECM with just the 4 normal cruise wires. Dont quote me on that. I think it needs to be set up as a trail blazer or something. Maybe give BP automotive a call.
