@Adamw It works! When I press the throttle the pump raises its RPM and when I let go, it lowers it. It seems that it cannot go to 0 RPM tho, maybe I should just switch it off with a condition if the wheel speed is over 200km/h. Thanks once again!!! I have changed the TPS on the GP PWM graph with Wheel speed, hopefully, it will work that way. I have one question about the streams, I see that you have used an %Ethanol in there, hopefully, this won't cause trouble when I install a flex fuel sensor to measure the ethanol %. Sorry for my ignorance, I'm just new to all of this and not sure if it is related somehow. 3000gt Volvo EPAS CAN.pclx

Thank you so much! I will try it now and report back.

Just a little bump up.

Hey, @Adamw! Have you got any spare time to tinker with the MAP?

Hey Adam! Here is a file of my MAP. Thank you very much! The CAN port is Number 2. 3000gt current.pclx

Oh, man! Thank you for this info! I will have to read that some more times unless I'm able to assimilate it and understand all the bits. Can I send you the Map so you can do it properly? I will be glad to pay you if you would like me to.

Thank you, Adam. As I said, I will gladly pay for your time if you decide.

Come on guys is there really no one here who is capable of doing this? I'm willing to pay you if that is whats stopping you from helping out. It seems as if there are several controllers online that can control the pump via GPS speed signal, however, I would like to do so via the Link. Didn't spend that much money on it if it can't control one pump... It's really a shame

Thank you for the reply. I don't understand any of this... The pump is currently switched on via AUX 3 with the condition of the engine running. Not sure about that Keep Alive you're talking about, but I would like to be able to control the the pump via CAN, so it can be on 100% when VS is below 40kph and to be 0% when over 200kmh or something like that.

Hello. I have a Link G4X P&P for Evo I-III and I would like to control my Volvo Electric Power Steering Pump via CAN. Does anyone have the ability to help me out? I found some info about the can codes that operate the pump, but I'm not smart enough to know what they mean and how to make it work in the PC Link Software. Here is a link to the article: https://rusefi.com/forum/viewtopic.php?p=45441#p45441 Here are the LUA codes: -- "alive" message from pump canRxAdd(0x1B200002) local pumpAlive = Timer.new() function onCanRx(bus, id, dlc, data) if id == 0x1B200002 then pumpAlive:reset() end end local data_0x1ae0092c = { 0x00, 0x00, 0x22, 0xe0, 0x41, 0x90, 0x00, 0x00 } local data_0x02104136 = { 0xbb, 0x00, 0x3f, 0xff, 0x06, 0xe0, 0x00, 0x00 } local slowCounter = 0 local slowRoll = 0 local slowRollTable = { 0x00, 0x40, 0x80, 0xC0 } -- car stopped is 0 -- car "moving fast" is 6000 (whatever that means?) local speedVal = 1000 function onTick() if pumpAlive:getElapsedSeconds() < 1 then -- Ignition on frame: sends every 30th speed frame if slowCounter == 0 then -- cycle through 0, 40, 80, c0 slowRoll = (slowRoll + 1) & 3 data_0x1ae0092c[1] = slowRollTable[slowRoll + 1] txCan(1, 0x1ae0092c, 1, data_0x1ae0092c) slowCounter = 30 end slowCounter = slowCounter - 1 data_0x02104136[7] = (speedVal >> 8) & 0xFF data_0x02104136[8] = speedVal & 0xFF -- pump speed frame txCan(1, 0x02104136, 1, data_0x02104136) end end setTickRate(71) Also, I know that MAXX ECU has cracked the code to make this pump works on their CAN and there is some info about this on the exact same threat on this forum: maxxecu sends IDs 2104136 and 1ae0092c to the pump2104136 is ~71.4hz1ae0092c is ~2.38hzexact 30:1 ratiopump responds at 11.84hz, which is 1/6 the rate of 2104136 I will be very thankful if anyone has the ability to help me out with this! Cheers!

Hey! I haven't had time to tinker with this. I copied the ChromedECU ignition degrees without reducing them, but I don't really go much into boost anyway, because I've put my solenoid at 0. I will install a knock-block that I purchased from Link and monitor the knock with headphones to see how the engine works with that timing once I have the time. Then I will set the threshold and call it a day. I will update once I figure everything out.

Hello! Have you found a way to control the Volvo steering pump with your Link?

Hello there! Have you found a way to control this steering pump? I have a Volvo PS pump and a Link G4X and I would like to know if it's possible to control it through the ECU.

Ok, so far I have managed to normalise idle and get a steady cruise tune to be able to move the car around. However, I have one concern to dive into steady state fuel and ignition tuning and therefore full power tuning after that, because I do not have a pair of knock monitoring headphones and while I am aware of how to set up the knock detection, I'm not sure of what threshold and gain to use without being able to listen for knock. Does anyone have any idea about the particular engine, a 6G72 Turbo in stock condition, what would be a good threshold and gain setting? Also, I've calculated the knock frequency to be around the 6Khz mark, but I heard that the second harmonic at 12Khz is better to be used for knock monitoring. I would be very glad if someone helps me with this.

I will be making a post once I manage to get everything going as it should.

Got it!

No, my car has a hotwired Walbro 450LPH fuel pump and Deatschwerks FPR, running 43PSI base pressure. Thank you for noticing! Yes, I completely understand that but thought the pins can be changed via the software.

Hello again. So I have managed to get the engine up and running, but it behaves very strange and I can't figure out why. When I drive and get on the gas to build more load, the fuel mixture becomes leaner and leaner the more load there is. Vice versa, when there is less and less load, the fuel mixture becomes richer and richer until eventually goes to 9. Can this be from an improper setup on the MAP sensor or a bad vacuum hose that's running to the MAP? Also when I press the gas pedal fast, the car stalls for a second and then revs. However, this seems like has gone away from itself... I haven't connected the lambda to the ECU but monitor it from my cockpit. Can this also be an issue? I attach the base map and a log of the car running if someone can help me figure out the problem. Also, I have a question about some pinouts. I had to physically change the pin for Ignition 3 because I didn't find a way to do it from the software. Am I missing something or is it not possible to change that from the software? 3000GT.pclx PC Datalog - 2023-06-18 11;11;00 pm.llgx

Thank you for the advice. I have an AEM Uego X-series from my previous build that is still on the car. Is it possible to connect it to the Link ECU or not?

I have a general Pinout for the 91-93 3000GT Turbo. I'm not 100% if my particular ECU is the same. 3s_1991-1993_ecu_pins.xls

I will try to run my 3000GT with the Link G4X for the EVO 1-3, but it has 2 oxygen sensors, which are connected to pins 55 and 56. The Link has Oxygene to 56, but 55 is NC. Btw if you or anyone else has a good running map for the stock 3000GT, I am willing to pay for it.

Hello everyone. I'm new to the programmable ECU game, but I like to tinker with things and have some basic knowledge about tuning, however, I would like to ask you a question. Is it possible to assign an engine attribute to a particular "NC" pin via the software? Let's say I want to assign a second oxygen sensor to an "NC" pin 55. Is this possible and how to do it?

Hey did you used a Link for EVO 4-8 or link for EVO 1-3? Have you figured out everything to run your car smoothly?
