  1. LS2 Crank Sensor looks wrong

    in G4+

    Posted

    Hi Adam, as usual you got a use sorted which is why we used a Link ECU on the job.  Its a friends hand built Lola T70  from hand shaped aluminum sheet for the chassis, its a true work of art.  Hand built throttle bodies etc

    Thanks for your help.

  2. LS2 Crank Sensor looks wrong

    in G4+

    Posted

    It turns out the engine builder used the 24 tooth in the LS2, we changed to the correct sensor you showed above but we no longer got any signal from the crank.  We checked the wiring and we still haven't done any good.  I wonder if the 24 wheel will work in a LS 2 / L98 block.

    Do wee need to change any setting in the link for the 24 tooth???

    Tomorrow is another day.

    Yes, you can switch between up to 3 tables.

    Okay so I should be able to use this to help down shift on a sequential using a PLC to call up the correct table.

    Thanks again

  8. Gear display

    in G4+

    Sorry for the confusion Adam,

    I have a electric gear change on a Subaru Manual gearbox, it is operated by a PLC and two Servo motors.  The output from the PLC to tell me what gear I am in in 3 wirer going to a encoder chip then to a 8 Segment display.  The 3 wires represent the gear, if first and second wire is on then that 1 &2 so third gear.  If the first and third are on then that's 1 & 4 so 5 the gear.  I was hoping that if I input those wires to the ECU I could tell it what gear its in.

    I maybe asking to much.

    Hi,

    I want to use the 5V from the ECU to drive a 8 segment display showing what gear the car is in,

    second question can  Extreme ECU read binary inputs to show what gear it's in?

    I have a tuned a LS3 with a G4X, but really only have basic start up maps for G4+.  What ECU do you have?

    Hi Adam,

    We haven't brought the ECU yet so my guess it will be a G4X, he does need 2 by DBW, it has ITB .

    Also do you have a preference for which model ECU Adam, I personally run all Thunder which aren't out in G4X yet I think.

  13. Help Understanding How Link Control the Subaru AVCS

    in G4+

    Posted

    I would really appreciate it if some one could explain to me how the AVCS is controlled on the Subaru EJ engines.

    The engine has AVCS on the intake only I currently have it turned off.  It is my understanding which maybe wrong that when off the cam will be fixed in one center position.  I assume that when the Link is set up I can retard or advance the cam 10 degree each way.  If so how is this done?

    The ECU is a G4+ Thunder.  The Cams are from a WRX and have 3 groves for the sensor to pick up.

    The only way to do that would be to have a single cell for the e-throttle target table, click on it, and use shift A or shift Q to bump up/down.  Or just type in a new value if you need a big change 

    Thanks Adam.

    Can I control the DBW throttle from a laptop using PC Link?

    The engine is a Subaru EJ DOHC and thunder G4+, engine runs with foot peddle just like to control from the lab.  I could wire in a different peddle but I was thinking there may be easier ways.

    All Sorted we have a running engine.

    Because its a flat 4 cylinder 1 and 2, 3 and 4 are 360 degree opposite so I swapped the pins on the ECU plug.  Next thing you know she is firing took a while to get rid of the gut of fuel but once clear it fired up on all cylinder and I now have it idling so I can do a tune.

    I assume I will need to adjust the injector time by 360 degree?

    Thanks for your help Adam, I feel sorrow asking for help.

    You have very obvious trigger error in the video.  RPM should not bounce around like that.  You need to set trigger 2 to hall/opto.  Pull-up on.  Not sure if it will need rising or falling edge, possibly either will work.  I would try rising first.

    Okay done and the rpm is acting normal and calibration is doing the correct thing as well , I haven't been able to get it to fire during cranking, if when its stopped I do a spark check it will sometimes fire.   It maybe a wiring problem which I will check.

    Have attached the latest log file,

    I have some sort of issue as the calibration change doesn't exactly relate to what I see on the timing light.  I maybe assuming incorrectly that a change of 10 degree on the Calibration setup will cause a change of 10 on the crank but it seems to cause a change of 20 degree but its not so simple, it appears that it will move a different amount depending on were it is on the tooth.  Pretty sure I can't get it to run this way but I will experiment with it a bit more and see.

    Any idea's would be appreciated.
