  1. SR20DET Timing Sync Problem Stock CAS

    in G4x

    Can you do a couple of trigger scopes captures as well.  One at idle and maybe one with a free rev to somewhere close to the RPM where the issue occurs.  Im not sure if the scope will have a high enough sample rate to give us any useful info at high RPM but it may still give us some clues.

    Those SR20 external ignitors can cause issues too since the return path is a very large loop and the high current ground goes through the ecu.    

    There was another user on here a couple of weeks ago with a trigger error on a SR20/external ignitor, he had even swapped to an aftermarket trigger kit without solving it.  In the end he swapped to R8 coils and that solved it.  

     

    Adam, I spoke with the owner of the car yesterday and discussed eliminating the ignitor and going with readily available 350z coils.

    Plugs are gapped at .28 I was wondering about the optical being an issue as well. Figured we'd try the wheel and then if that didn't do it just bite the bullet on one of those $500 trigger kits. The log file I sent was revving the car in neutral. It happens just the same on the dyno.

    it's Paul Chamberlin's new car (Wiseconcepts) I think you two know each other.

    Yes sir.  I know Paul from back when he lived in texas many moons ago.  I spoke with him on the phone a hour or so ago.  The aem disc wont fix an optical issue at all.  Let me review the cal and log and ill get back with yall.

  4. Altezza Cluster on AE86 Speedo

    in G4x

    The only things in the cluster that is CAN based is the coolant temp and some of the small indicator lamps. 

    You should be fine with most everything else.

    I have done both the altezza plug in and link wire in unit on multiple IS300s with factory cluster.

  5. Need help with 1UZ VVTI

  8. Secondary Fuel Pump Setup G4+

    in G4+

    Posted

    Wiring is correct as described, just make sure that the 12v source on 85 is switched with key.

    Set up general purpose out put as IGn8 and switch conditions to Map > X.

    I would add conditions to secondary fuel pump to include if the primary pump is on, differential fuel pressure < Y, Inj duty>Z, etc. 

    You can get creative with adding different logic to trigger the second pump.

  12. Boost Nightmare!

    Is the fire ring/valve seat for the WG valve in place between the WG and the manifold? That is the main reason I can come up with for had boost now you dont.

    And adding springs will not fix a creep issue.  That is an issue caused by too small of a gate or poor wastegate priority.  Id bet on priority as you have a 66mm gate.

  15. 2nd knock sensor

    in G4x

    Posted

    I may be incorrect, but from the last convo I had with Adam regarding this exact scenerio(2jz w/ altezza pnp), I recall him telling me to just wire both sensors to the same input pin and just adjust your gains as necessary.

  19. Controlling external DC motor using E-throttle pins

    in G4x

    Posted

    For tps you will want a 3uz from a tundra or sequoia.  They are a direct replacement for the ae111 black top tps. And available at most parts stores.

    Ive played maxon motor games and have a couple in a drawer.  You can also stack the planetary gear sets for better drive ratios if necessary.  But in the application where I was aiming to use a maxon motor, i just ended up with a billet ATPower unit.

    For my Black top throttles on my beams motor, i just used the e46 bmw M3 actuator, works fantastic.

  21. AEM Series X Wideband Into Link G4X

    Curious I haven't seen this anywhere on subaru forums That AEM wideband 02 sensor have terrible analog outputs? And confused what u mean by analog outputs? It works on voltage output signal and send to ecu ? I've seen heaps of 600hp STI with AEM Wideband and never reported a problem ?

    There is normally a slight discrepancy from what the aem uego gauge will show vs what is seen in the ecu.  You can fudge the 0-5v curve in the ecu to get it closer, but there will still be a slight discrepancy.

  22. Aux Out (Ign) voltage

    Won't the lower voltage on Ign 5 effect the operation of the solenoid and require a higher duty cycle as a result? Tuning on the car had already been done, won't this require a retune of the boost control?

    boost solenoid aux operation drives to ground, so positive voltage level will have no effects.

  23. G4+storm ecu

    in G4+

    Posted

    Are you basically seeking the unlock code for the ecu?

    If so, in your situation, you will need to get with Link HQ NZ and supply the serial number(should be on end of ecu) and they can try to help you sort that out.

    yes the snake trail will show  you were the over run area of the ignition table is.  Typically i would expect something in the region of 30-35 deg on over run while not trying to sound like a fart box.  I would drop that down to to sub 10 deg, maybe into the negatives if  you really want some spicy farts.  Its all about getting the fuel mix to combust in the exhaust.
