  1. G5 GPS

    in G5

    Posted

    Hello all.

    I am on the Firmware which enabled WiFi

    And this is my configuration. 

    I had thought i'd enabled GPS but it doesnt seem I have it in the runtime values.

    Anyone know what could be the cause of this? 

    I did not set "reset" to "active" as that does not seem like it turns on the GPS? Am I missing the mark here?

    The help file does not seem to suggest that anything other than just connecting it and setting to Interal is needed.


    Any help would be much appreciated.



    What I'm trying to do is have some traction control using GPS as the front wheel speeds( long story but I cannot get front wheel speed via sensors ) vs my rear wheel speed ( working both fine ).

     

    Also does anyone have some starting point values to setup traction control?

    The end goal is to use an incremement keypad button to switch between different slip allowances

  3. Idle Up when in Gear

    in G5

    Posted

    I should clarify that I send gear over can. I don't have a neutral or park switch in this case.

     

    So Basically I'd like to have a function that says

    if Gear == [ R, 1, 2 ] && idle == active

    then 
    offsetIdle(x)


    Where x could be a percentage or a static number

  4. Idle Up when in Gear

    Hey folks - I'm working around some deficiencies of a trans controller ( dual clutch trans ) and im wondering if someone has an idea how I may accomplish this..

    My car idles very nicely around 900 rpm ( shoutout to the gent who tuned my car ). Without going to deep into the trans controller.. the car seems to go very low RPM when attempting to move forward. However I noticed when in warm up still - when the idle is higher, this is a non issue.

    Is there some way to take gear ( which is sent to link ) and idle up when 

    Idle active

    Gear = R, 1 , 2 ?



    Thanks!

  8. Transmit to Link/Aim MXG

    in G5

    Posted

    Heya folks - I'm trying to better understand how to handle some of these custom can bits. I have a custom can file provided by the Link Team ( thank you ) 

    But I'm trying to now send also in that can file - clutch temperature ( CAN AN13 ).. and I can't for the life of me figure out how

    https://drive.google.com/file/d/1nDTLSYIFdmk3Q_2xUufUk5ahEawp7Mne/view?usp=sharing

    Here is the file... Would anyone be willing to do me a solid and either tell me how to modify this myself in the future or help me make the change? I believe this was previously mapped to CAN AN14 and has sense needed to be moved... so since then it's been broken.



    Thanks a lot!

  12. G5 Log Mark Function

    in G5

    Posted

    Wanted to separate this from my previous question as it's a bit different so sorry for the spam.

    Is it possible to bind a "mark" function in the logs via a can keypad button?

    I'm finding it difficult (hobbyist) to determine where a given event that I'd like to review actually is in the logs.


    Thanks!

  13. Blink Marine keypad increment boost by gear

    in G5

    Posted

    Hey folks. I'm looking to setup something extended from the normal boost gear wastegate trim table. What I would like to do is modify the value in the table based on a button positon.

    I'm making a few assumptions here. So for a good chunk of my map we are at 0%  duty cycle, and most of the rest we are at 65%.

    So -

    Button Status 1 ( LED state 0 - off  ) No modifications to the table

    Button Status 2 ( LED State 1 - red ) Modify the wastegate trim table for gears 1,2,3 ( the only gears we ever modify ) by -100% ... to set to gate pressure

    Button Status 3 ( LED State 3 - cyan ) Modify the wastegate trim table for gears 1,2,3 ( the only gears we ever modify ) by -50%.. to set to 50% of gate pressure.

    Would someone be willing to provide an explanation of how to setup a button to perform this function?


    Thanks!

  15. 2 Wire Hall Effect Wheel Speed Sensor Usage

    You really need to get an oscilloscope on it so you can see what the signals are doing

    I'm just gonna do the silly thing and do the converters first. It's simple enough to do and it's confirmed working with these sensors.

     

    If that doesn't work the oscilloscope it is.

     

     

    Is there any truth that beyond DI 4, You can't do VR wheel speed? It's just a thought from reading the docs, not conclusive so I figured I'd ask.

    I found a couple of service manuals for a XV40 camry, both of them suggest they have normal VR/AC wheel speed sensors.

    But then a google image search suggests there may not all be that type.  Both these pics below are for XV40 camry front wheel speed sensors.

    If your sensors look like this one with a cylindrical body and a pole piece visibly poking out the end in the centre then I would say that is almost definitely VR.

    However if it looks more like a flattened blade like this one below, then I would lean more towards it being an MR/Active type.

    Ah yes- looks like the first image... 

    So this indicates it should work no? I'm not sure whats up...

    Here's how its wired.

    I understand this could possibly be reversed accidentally.

    Wheel speeds go:

    1 Wire into a sensor ground. Pin 24 of the " A " Plug on the ecu. ( shared amongst the two rear wheel speeds )
    1 Wire to a DI

    I suspect these will be magnetoresistive sensors.  I didnt look for info on the camry, but the info below is from a 3rd gen rav4 manual.  You can see it shows a squarewave signal with 2 different current levels.

    So these would need the matching RAV4 magnetic target wheels and wouldnt work with stock MR2 ABS.  

    They can be quite tricky to make work, you need to experiment with different combinations of supply voltages and pull-up/down values to convert the variable current into a variable voltage.  The fixed switching thresholds of the G4X DI's often arent well suited for this type of sensor.  Some basic info here:   https://www.motec.com.au/filedownload.php/CTN0007 Magneto Resistive Sensors.pdf?docid=3634

    Interesting. We do use rav4 in the front. So should I do the vr to hall effect converter?

    Okay I just watched frequency. No data all the way up to 70kph. I've tried pullups on and off.

    okay edit just popped a sensor out. Put a magnet to it, No frequency change.

     

     

     

    Someone I know seems to think you have to have a VR to hall effect sensor converter and that works for them. So perhaps I should do that.

    The Trigger scope function does monitor the first 4 DI inputs if you run a trigger test while spinning a wheel, but it doesn't actually show you the shape of the wave form like a real oscilloscope would, rather just a active/inactive square wave looking pattern when set up properly.  Conversely you could attach the sensor inputs to Trig1 or Trig2 inputs and those do show wave-form like a real scope and you could use them using the capture function while spinning the wheels manually (or having a friend spin the wheels) - obviously the vehicle can't run in this situation and you would want to be careful to make sure injectors and ingition are disabled just in case while performing this testing.

    Hm that will be difficult as my harness is pretty much fully sealed. Is this just a case of maybe the wheel speed calibration is off?
