  1. SR20DET CAS Woes

    I have done 3 SR20’s on G4X with stock CAS with no drama.  Only mild cars with stock cams however.

    I did a couple SR20s on stock cas with no drama 2 weekends ago.  This was on beta software/firmware for the comms issues.

  3. PnP ECU Bench Power

    in G4x

    Posted

    Id just go to all the appropriate pins on the header.  But its typically just 1 or 2 pins that need power.  Ill check my notes when i get home, as i have made bench harnesses for 02-05wrx and 04-07sti.

     

  4. PC Link locking up/Disconnecting while engine running & No RS232 with G4x?

    In the next PC Link release (release tentatively planned for next week) there is a totally new direct USB connection method that bypasses the virtual com port system altogether, and for the few people with problem connections that have tried it so far it has been encouraging.  I will PM you a link to try.

    Can you shoot me this link as well @Adamw???

  6. 2JZGE sensors

    Hmmm, that is quite a lot. It would seem to be a good move then to fit a crankshaft mounted sensor.

     

    its been a long while since ive played with the 3sgte stuff(have a 3sge beams in my car these days) but from memory, the later model 5s/gen4 3s stuff bolts on to add a nice factory component crank trigger setup.  

    did a quick search, here ya go....

    basically 97+ 5s pump and sensor with a gen4 3s crank gear. 

  9. V88 to G4X upgrade and Reluctor Interface?

    Thanks for the reply.  That actually helps things make a bit more sense.  I remember there being missfire issues with this motor at high boost levels, so if the Autronic interface doesn't need to be there, I'm now thinking maybe it was added in an attempt to fix that problem?  I do know that in the end, the fix for the missfire was to switch to CDI ignition which the car has also been running fine with for 10 years.  Which means yeah, by the sounds of it I can ditch the Autronic interface.  Thanks.

    could 100% see installing the autronic interface in an attempt to address a misfire scenario.  

  12. Fault code 76. Dbw ethrottle tps tracking error

    Yeah, they are not available at the moment due to the different way the safety system works in G4X, it was assumed by the firmware guys that they werent needed/used but it was one of the first things I complained about after tuning my first G4X.  So it is on the list to add some similar functionality back in or develop some new diagnostic tool so you can more easily see how close you are to breaking the camels back.  It is still a little while off, looks to be scheduled for 6.19 firmware. 

    Oh man.... here i am with a ITB 1uz with that single ATPower actuator, im sure you can imagine the struggle with out those values.

    Was a big surprise when i went to set up my usual DBW diag page and those values weren't there. 

    "Am I just supposed to hope and pray and shoot in the dark?" were the exact words that came out of my mouth.

  17. Steering position

    in G4x

    Posted

    @Adamw when i say silly, I'm more referring to the fact that the parameter is there but its bound only to CAN.  

    With it set up as a GP Input and a math channel, can these values be viewed utilizing the "vehicle plan" data view?

    And is there any way to utilize this with closed loop control for a target rack pressure based on vehicle speed and steering ROC?

  18. Steering position

    in G4x

    Posted

    I have a sw20 mr2 electronic power steering pump powered via a 100a crydom SSR, steering rack pressure sensor, and a string linear potentiometer on the column for steering position.

    Im trying to greatly over complicate things and would like to configure a closed loop steering set up with multiple tables for on the fly switching via 2 DIs on a rocker switch.  

    Have been through the software a few times and currently just the steering configured via a 3d table with driven speed(g4+ would have been non driven) on one axis and engine rpm on the other.

    First hurdle that im finding is that the parameter "steering position" and "steering position ROC" are stated to only be able to come in via CAN in G4X.

    These parameters are quite vital to the control strategy that im envisioning.  Im sure i could work around this with a GP ANV and a math channel but it just seems silly to have to do so.  

    Any ideas on this overly complicated adventure would be super.

  23. Force closed loop idle lockout on AP% and a few other E-throttle questions

    I tried doing this at first but the control was not fine enough. I had to run very retarded timing at idle to limit engine torque and this ended up pushing idle exhaust gas temperature higher than i was comfortable with. I drive the car on the street mostly and sit in traffic on hot days. Apart from the closed loop idle issue the setup has worked extremely well.

    Understood.  Im sure there may have been a way to sort that out, but I do understand there are many solutions to most problems and not all of them are wrong.

  25. Too high VE issue

    I dont think so.  JMP's suggestion is a good one though, well worth a try.

    I know it probably wont make much traction to add that to the software for G4+ but I believe this is a parameter that would be nice to have in G4X.
