DIY Volvo Power Steering Pump Controller and Camaro Drifting
ฝัง
- เผยแพร่เมื่อ 20 มิ.ย. 2024
- This video goes through how I made a CAN bus controller for an electric Volvo power steering pump and put it in my drift Camaro. Then we have some drone footage from Spirit Peaks Raceway at the end.
~~~ READ BEFORE ATTEMPTING ~~~
Please note that I made a mistake in the video regarding the power steering rack lines. It should be that the 16mm (top port on the rack) is the return line and the 18mm (bottom port on the rack) is the high pressure. The diagram in the Github repo has been updated to show the correct information.
I also had issues with the controller working unreliably due to the MCP2515 board not getting enough voltage. It needs at least 4.75V to operate and the Nano would sometimes output below that threshold. I now recommend powering the MCP2515 directly from the 12-5V converter rather than from the Arduino as shown in this video.

Thanks for sharing!! Do you know what Ohm value the potentiometer you used was?
@@porterthenobody I used a 10k ohm potentiometer
@@shortgirllongcar thank you!
Hey come on now, could have at least given me credit for using my source. You even left my comments in there.
I just added links to all the sources I used for the script in the code itself, repo readme, video description, and parts list Google doc. I am really sorry for not adding this in and giving credit earlier, that was a mistake on my part.
Thanks for showing this. Most of the videos show how to weld the pump to the car and then provide 12V to the trigger wire but seems like hardly anyone delves into how to actually control the pump.
This is a fantastic, extremely well made video! My only suggestion if you make more would be to try to even out your audio levels, and get them up into the preferred range during the edit. Still an amazing first video!!
Great video! Precise, well documented, clear audio - I like that the explanation portion runs w/o all the annoying royalty-free soundtrack so many ppl use. EU based Ebay seller carries the GPS based controller for complete hands-free speed vs. pump pressure, if that is needed.
Running some kind of crappy music over dialog on an educational video should just get the video taken down lol.
Fantastic video! Impressed!
Nice job. Congrats on your build.
Very rad! Looking forward to more videos
Great tech video.
Great first video. Clear, concise, and fantastic details.
Complete Clear and Detailed
Such a detailed and helpful video, thanks!
very good explanation nice video
Thanks. Found this helpful and informative
Soooo awesome!!! Great job! I just picked up one of these pumps today to swap into my mustang.
Excellent info and great job! Thanks.
This is the best video on the topic by far! Nice driving at the end too.
Awesome video! I have a 4th gen firebird I want to to the same. This will help me. Thank you for sharing
Thanks for the vid! I bought a pump years ago and just got to putting it on, this helps refresh!
Nicely done. I'm going to do this exact mod to my catfish. It's a drag car so I don't need the can bus controller quite yet.
Great video!
I’m doing this to my Foxbody in conjunction with a hydra boost brake setup. Thanks for the Good informative video!
How did you do it?
Great First video. Very informative!
great vid!
Great video. I wasn't expecting a breakdown of the canbus signals. Excellent. Its nice seeing this done in a GM application. I am planning this conversion for my Caprice Wagon. Right now it has a manual rack from an S10 and the only belt driven accessory is the low mounted alternator. I am planning to install a faster ratio powered steering box and powering it with a Volvo pump. I would imagine that my plumbing will be similar except for the fact that I have an old school steering box with a pitman arm instead of rack and pinion steering.
Nice work I am trying to find a pump like that for my v8 s10 tired of manual steering nice video
nice video thank you
Awesome from one 4th gen girl to another! I'm putting a volvo pump into an LT1 that is getting twin turbos (to save space).
Also you're the first one that has shown the canbus wiring, most just use the one wire as a trigger wire. Which is all I was going to do.
Glad you found it useful! Best of luck with the twin turbo setup, sounds like fun!
Great first video, very informative!
Ive been researching how to reasonably control a Volvo pump to mount on my 89 Mustang. I think your solution is pretty close to what I was envisioning! I love DIY so this is right up my alley. Thanks Again for sharing!
Thank you, I'm glad you found it useful! Wishing you all the best with your Mustang
@@shortgirllongcar and best of luck to you on your new channel!! Im just starting out mine too LOL
@@porterthenobody nice! I'll have to check it out!
I'm the process of doing it in my 89 mustang right now and the pump fits under in the front of drivers side fender next to where the horns mount and found controller of ebay for variable speed for pump but at least 3week for delivery on that. And get pump with mounting bracket since it has isolators and make brackets off that. Hope that helps.
@@georgemixter1136 Yeah the one I have I grabbed all the bracketry, as well as the remote mount reservoir! I saw likely the same controller kit you saw - I think it was coming from Portugal...
❤great job
This is fantastic video on the subject. Very detailed and informative. Keep up great work. I wonder what your next project might be 😊
I have been using the same pump on my Jaguar EV Conversion with my own CAN controller for over 2 years and it works great. For me the biggest benefit of CAN control was eliminating annoying start delay since I switch pump OFF in P and turn ON in D and R position. The only issue I ran into was with bearing since my pump is 18 years old from high mileage car. I have video on my channel how to fix it if anyone is interested.
Thank you for the kind words. It's good to hear that the pump has been treating you well long term and I'll definitely be checking out your rebuild video once mine starts getting tired.
Great video, awesome job on the controller. I’m thinking about doing this on my ls swapped e36 but want the control of the pressure. Trying to think about a way to tie it into my Holley terminator x with the can module cause I can do pwm output. This video is a big help 😊
Thanks, glad it was useful to you! Best of luck with the e36, sounds like a really fun project :)
Thank you for the info! I just put a volvo pump on mine, but I run a MS3 computer that has CAN capabilities. "CAN" I use parts of this code to get my ecu to control the pump?
I haven't had any issues with the pump in "limp mode" but it would be cool to learn how to use more CAN stuff.
Yes, feel free to do that! And check out the code credits for more examples on how to set up the CAN part of this
How was that your first video!?! That was amazing!
One thing I wonder, would a controller like that work the same on other power steering pump models, like the mr2 or astra?
Thank you! And in terms of this working for other pumps - I think the MR2 one uses a PWM signal instead of canbus to control speed so that would actually be a bit simpler to make a controller for than this one for the Volvo pump
Thank you so much, I have been searching for this kind of information. May I ask you a question? Does your package use the vehicle speed signal to change the pressure value?
Sure, glad you found it helpful! Yes, technically we are using the vehicle speed canbus message to control the pump but in my setup that message is varied by the potentiometer not by the actual vehicle speed.
Great first TH-cam video. Keep up the great work. I did this swap quite awhile ago and before DIY controllers were common. Actually removed the setup due to feedback issues when braking and steering inputs overlapped. This would cause the steering feedback momentarily pause and resume once I eased off the brakes. That was 100% due to not enough line pressure and the default pump speed.
Autocross was not fun.
Anyhow, I’m coming back to the Volvo setup and I’m going to be running a similar potentiometer/controller. Very curious if you’ve experienced anything similar to what I just described?
Thank you. I tested my car on the street for a few weeks without the controller and that sounds similar to what I felt. I would try weaving back and forth aggressively and feel the pump not really work after a turn or two. The feel now is maybe not 100% as good as hyrdaulic but it's not an impediment like it was without the controller. I've done probably 4 more drift events since posting this video and it hasn't been a problem.
small thing about the fiberglass heat resistand sleeving
if its simulair stuff to the exhaust wrap than be verry carefull when you have oil and transmission fluid leaks , friend of mine had exhaust wrap and had transmissionoil drip on it , one day people where signalling him to check under his truck so he pulled over and was just in time extingueshing the fire under the floor of his truck , the stuff soaks up oil like a sponge
Thanks for the comment. It's an important thing to keep in mind and probably something I should have mentioned. I had a similar scare on my DSM with a turbo blanket starting to smoke due to an oil leak. You have to be able to check for leaks on a regular basis and always keep a fire extinguisher handy although the sleeving might not be worth the risk if you have a car that doesn't see track time.
You could probably add a gps module to allow it to slow down the pump when you get over a certain speed. I believe i read thats how the pump works in the volvo it came out of. but probably not a big concern for drifting
I thought about trying that but with drifting I didn't think it was worth the hassle. I worry the GPS wouldn't update fast enough and I wouldn't have enough power steering when I need it. You are right though, the pump normally takes in vehicle speed information to determine what speed to run the pump at. Would be a cool thing to try out for a street/grip car!
Thanks very much for such an indepth DIY. As others have mentioned, almost all the people who have used this swap have only connected the signal wire and had the pump running on limited capacity. And for a 1st video, you have done a great job so please keep posting more 👍.
I'm sure about the fact that this pump's onboard canbus has multiple sensor reading capability (steering wheel movement speed, vehicle speed and more). Amazing how you have used Arduino to control the speed of the pump with a canbus board. I do have a question related to that - is it possible to use arduino to read the speed of the vehicle(from VSS) and control the pump speed to dynamically change as per the VSS?
Thank you for the kind words! It should be very possible to have the pump change speed based on the VSS, the hardest part would be turning the signal from it into something the Arduino can read. Then you would just have to modify the code to change the speed based on that signal rather than the potentiometer position. I know I've seen people do this with a GPS speed signal but I would worry about that being reliable enough for something like this. Hopefully that helps!
🤯🤯🤯🤯👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼
It could be posible to take that signal from the speed input for the ecu instead of a potenciometer, to make it automatic?
It's definitely possible. I know some people already get speed from a GPS module to control the pump speed. Shouldn't be much different if, for example, your car has OBDII and you grab speed from that. You would just have to modify the Arduino code a bit.
Great Job on this Video! very informative! and also thanks for the warnings and highlights that one should for!
Any Idea if this works on a BMW rack? been searching for someone who tried it on a BMW but cant find any...:(
I did find this one forum post (www.e46fanatics.com/threads/electric-hydraulic-power-steering-conversion.1250691/page-3#post-18528415) where it looks like someone successfully put an MR2 pump in an E46 but not much info outside of that. Make sure to comment if you try it, I'm curious to hear if it works.
@@shortgirllongcar Sadly that post wasnt from a drifter :P he's happy that it feels heavier than stock steering :(
That is far from what I want on my wisefab lol! I do have a Mercedes A-Class Electric steering pump on my E36 but it doesn't feel that powerful and the steering gets really heavy in some situations!
I'm looking for something that would allow for lighter steering and faster self-centering!
Anyway thanks for your reply and sure I'll get back to you if I ever found a solution! :D
😎👍
thank you! This has been an annoying issue with mine as well, just out of curiosity what did you do for the belt path? Did you put in a dummy/idler pulley where the power steering pump used to be?
I was able to make mine work by just getting a shorter belt. I basically just followed this forum post: ls1tech.com/forums/new-ls1-owners-newbie-tech/1281701-solution-ls1-no-power-steering.html#post13339959 . Not sure if you have an LS1 but hopefully there's some info online for your car's belt routing for deleting power steering
@@shortgirllongcar thanks again!
A coding video would fantastic!
Thanks for the feedback! I've had a bit of a busy year but hope to get back to making some more videos here soon :)
I’ve seen multiple videos of the S 40 power steering pump and I was wondering if a cooler is not needed for this set up?
I have a small cooler on mine (you can see it at 5:48 in the video) and have not had any issues. Granted I don't have any way to monitor the temps on it but I haven't seen it try and boil over. If you are just street driving you might be able to get away with not using a cooler but since it's pretty cheap and easy I would put one on just to be safe
Man I could've used this 5 years ago lol. I went with a BrunoSteering controller.
Do you like the Brunosteering controller?
@@TheHilmar59 Yes
@@RollingRoadEFI great, just ordered one. Have a good day
Cool Video. Do you know if the code in the link provided can control a Mazda pump? The Link you provide to the code also has another link to a production version which looks to control Mazda.
I don't think the code will work for the Mazda pump but it could serve as a good starting point to trying to figure that out if you are so inclined. As far as other controllers people are selling go I haven't tried any of them personally but those are probably your best bet if you want a plug-and-play solution.
would you ever make these to sell ? great video btw
Thanks! And I currently do not plan on selling these
That s a project I’d like to replicate to make the pump run and appreciate the squealing noise it produce
Best of luck with your project. The noise isn't my favorite but as long as you keep it in the engine bay it isn't too bad lol
Hello
Why you dont use speed sensor? Thanks for sharing
For drifting I want the pump running at 100% power all the time but there are people who have used a GPS speed input for their controllers
Did you build all of your car?Maybe do some videos talking about it and looking at it what you did
I am actually about half way through making a video going over my car's setup so it's good to hear you are interested :) Should hopefully be out in the next few weeks
quote me if i’m wrong but if you use a arduino nano A000005 instead of the every you don’t need to use the converter from 12v to 5v cause the board has a built in converter basically forgot what the chip was called that does it i will be trying that board for mine will let y’all know if it actually works but awesome video all the info needed to do this thank you for showing us the way
Yes definitely report back on if that works, would be a nice way to simplify the setup a little bit
yea main reason i’m trying it out just got it all wired up, waiting for standoffs to come in going to put code in tonight and test tomorrow that de soldering of the headers not easy lol
i’ve tried many different was to upload code onto arduino ide and i’m completely lost please help!!!
@@brandonjacob3897 sure, if you have IG message me @michaela_buchanan or send me an email at mebucha2@gmail.com and I can try to see what's going on
@@brandonjacob3897Just curious did you ever end up figuring out if the converter is built in?
question, do the lines need to run to a cooler then the rack or not?
I don't think it's completely necessary especially if it's for a street car but I would highly recommend a cooler if you plan of doing a lot of spirited driving or any motorsports. Better safe than sorry in my opinion.
Is it possible for one to get an already programmed controller 🤔?
I believe there are a few companies starting to sell Volvo power steering controllers but I don't sell them personally. If you need help with just the programming part feel free to reach out
Volume was a little low. I like to see the person talking (you) during the video. You are good at explaining things and you did a good job showing what you're doing. Overall, well done.
Can this work for the mazda pump?
I don't know very much about the Mazda pumps but I would be surprised if this controller works with it out of the box. It does look like there are some controllers for sale that work with the Mazda pumps but outside of that I think you would have to research and experiment yourself to see what CANBUS messages you need for that pump.
0:37 Bro you have a supercharger😅😅
when uploading the code I get the error 'potvalue' was not declared in this scope
Sorry about that, looks like I had a few typos. I just updated the code in the GitHub repo so it should be fixed now - let me know if you have any more issues
V50 1,6diesel powersteering fluid
Sad, wanted to use this for ref in another vehicle but the audio is extremely low.
Any chance you'd be willing to build and sell one of these units?
Hi Brandon, I'm currently not making these for sale but you may want to check out this link. I haven't tried these personally but they seem like they should do the same thing. www.brunosteering.com/product/volvo-hydraulic-electric-power-steering-controller-kit-volvo-c30-c70-s40-v50/
I just ordered this controller, let’s see if it all works🤞
Just did this install on my 95 Camaro. Blew the seal out of the rack. The wheel was turning left and right all by itself. What could I have done wrong?
Have you double checked you didn't switch your high pressure and return lines? I accidently did that initially when I installed mine and had something similar happen
@@shortgirllongcar 16m should be high and 18m should be low? I need to double check
Sorry, looks like I screwed up in the video, it should be that the 16mm (top port on the rack) is the return line and the 18mm (bottom port on the rack) is the high pressure. Going to fix this in the video asap and sorry if this caused confusion/issues
@@shortgirllongcar i just dropped the rack and replaced the shaft seal. No big deal. It was the original seal from 1995 so it needed it.
gotcha, hope the rest of the project goes smoothly for you. Feel free to reach out if you have any more questions or issues!
Will make one of these for me ? Ill pay You ! I have been messing with this steering for ever , Need some help me with this
If you want to dm me on Instagram I might be able to help you out. It's @michaela_buchanan
Very nice job girly but I got to ask you a question any possible way I could pay you to give me one or do one for me so that way I don't have to do it I'm 59 years old and my brain don't work that good if you could I'll be more than happy to pay you for it thank you let me know
Hi Joe, I'm glad you liked the video. My soldering skills aren't good enough for me to feel good charging for it but if you search "volvo power steering controller" online there are a few companies that offer ready-to-go controllers to purchase so I would suggest giving that a try.
@@shortgirllongcar sweet thanks
Can you just make one and sell it to me?
I don't have any plans on selling these myself but I know there are others who have controllers for sale. If you Google it some options like the Bruno controller should come up
@@shortgirllongcar I bought one that is speed controlled by GPS.
