What info do you see when you do the vpd read?

Hello. We sell these controllers at reformmotorsports.com. Thanks!

Sir, for that year and model car! Can you tell me if it can only run with only a controller unit? Unlike the other pumps need only 3 wires for it to work with option for a controller. This pomp only work when you start up the car then stop instantly! Can't get it to work with the small 12v IGN wire like what I saw on KZbin. Could it be a faulty pump? Just 😊 😊 picking your brain a little my first time on this Volvo project, thanks .

Hey, unfortunately it does not.

@clutch-slayer ok thank you

i'm working now on my project, previously car had pump from opel astra, so soon i will test this kit with opel pump

Pretty sure it’s 1700psi at max load and 800-900psi operating

Most of the same steps can be used, put it in developer mode, use the vpd utility to change the "oem_device_requisition"="remora", or if you have a different model you'll need to look up the code name for the meet device.

Check out the comment further down by @chadklinefelter7081, he describes the opposite process

BrunoSteering lol. Guy made one that uses GPS speed.

They sell a gps version of this

@@Jay-zk7xk Yeah......

Whatever setting makes the steering assist the way you like it. It all depends on the power steering rack or box that's in your vehicle. Some systems use more or less pressure than others... Set it where you like it.

Same same :(

I did the same and ended up at the enrollment screen too😢

The pump will automatically change it's speed to try and maintain a constant line pressure according to wherever you have the controller set to. If it's set to 50%, the pump will vary it's speed to stay at 50% pressure under load. The pump CAN draw 80 amps at max output, and the amount it WILL draw during use will depend on your tire size, and how much pressure your power steering rack or box demands, and the load at which it takes to maintain the line pressure to whatever it's set at.

Then just replace the potemtiometer on the board with some wires leading to the same value in a bigger knob, that you have mounted on your dash.

Same here..

No

Please advise! For some reason on vpd -i RW_VPD -s "oem_device_requisition"="remora" step I have tons of messages about "...cannot read inside management engine region...". I've tried to remove FW write protection screw - same errors and device won't run on Meet mode after this commands and runs in standard mode anyway.

I’d like to know this as well. @whaddayawant2197 do you have an issue with it not pressurizing the hydro boost enough/causing kickback in the brake pedal? Because I’m pretty sure I need this controller to adjust the pump speed over 75%. I ordered one and hopefully it fixes it when it gets here

@cooperswift8625 I'm just making plans of what I'd like to do someday. And a healthy cam would benifit from a non vacum source for brakes. With hydroboost being on of the cheapest and best source. Pls inform us on your progress. Thanks.

@@whaddayawant2197 - I've personally installed this very pump in my Mustang that has hydroboost brakes and power steering. As cooperswift8625 suspects, the default pump speed isn't enough when braking/steering input overlap. [Makes autocross a CHALLENGE] Normal driving and even light open track duty was livable. I will be installing a controller in the next week and will report back if that helped. I'm suspecting the higher pump speed will work for me.

If the pump outputs enough pressure as required by your hydroboost system, yes, it will work.

@davelowets read hanomotorsports reply. The most accurate info I've seen.

It works now. Apparently I did write down wrong, should be: vpd -i RW_VPD -s "oem_device_requisition"="none" That is no spaces between the '=' sign.

I signed up with ChromeOS under my personal account, which cannot be done under Enterprise Enrollment. This video was very helpful!!

Glad to hear it worked for you, sorry for not seeing the comment earlier, sometimes KZbin doesn't like to notify me. Happy ChromeOS'ing!

Hello! Unfortunately the current draw changes depending on conditions and load. At "idle" with no load on the power steering pump, it will only pull 2-3 amps. However at full lock it can pull up to 80 regardless of pump speed.

The majority of the USDM Volvo EHPS pumps (04-13 40, 50, 70 series, etc.) do not run full speed with just ignition power. The "failsafe" condition when no CAN bus is detected will run the pump at about 75% of max speed. The intent for this board is a simple way to control the pump with a fixed speed, mostly for drift cars, or other Motorsports where you want consistent power steering feedback regardless of vehicle speed. The other version of the controller we've been developing allows mapping inputs from analog input such as a potentiometer or PWM output from a standalone ecu to allow changing speed on the fly or programatically, but also adds the ability to watch for messages on CAN bus and map the output based on watched messages. Modern standalone ECUs like MaxxECU are adding more CAN bus features, like EHPS control so it's a bit of a trade off if it's worth investing a lot of time into it. If you're interested in that side of things, feel free to reach out to us at rmehps.com and we can send over more info!

NO, your pump is NOT working wide open by applying power to the Grey wire. Doing that puts the pump in a "fail-safe" mode, and your only getting 75% of its full capability. Your loosing 25% by doing that.

Agreed

Relatively small turbo, also on a mustang dyno. Number doesn't mean much.

Hello, this is using ECUMaster which has the E46 CAN dash option. All gauges are working.

Hey! It’s definitely possible, we have another version of the controller that’s still in development that allows a pwm, or pulsed input and gives you a 3d table to control pump speed based off the input. Otherwise, if you’re crafty enough the basic code to make this work is available on my GitHub, you could make it work with an Arduino.

@@clutch-slayer Hey do you have a link to your github?

Hello! Can you send us a message if you got this controller from us, either on eBay or on the reformmotorsports.com using the contact us form? Can you check your battery voltage with a multimeter? KZbin doesn’t always notify me when people comment so I apologize for missing this.

@@clutch-slayer battery voltage is right altonater is charging right and my low and high can wiring is right .I don't use the control because it's on a ford st225 focus. Thanks for replying back.

I would say the motor on the pump is prolly going bad. Similar issues exist with fan motors and starters the brushes wear out and by u turning or smacking it gets it going again.

Good day.. how much.. can I used the module in Nissan with can bus EPS thank you

Your pump motor is SHOT

Hello, I do not believe it will work with that pump, however we have not tested it.

same pump
