  2. 2001 JDM B4 Legacy Fuel Pump Issue with PNP board

    in G4x

    Posted

    Just installed a WRX6 PNP to a 2001 B4 legacy and it seems like its not connected to fuel pump (don't get prime at IGN switch on).

    Found that the vehicle has a pump control unit and traced a wire (light green) to a pin on the B135 connector.

    Should i move this to AUX 1 pin and setup AUX 1 to a speed PWM setting?

    NOTE: vehicle starts with present setup. There is presently a wire in AUX 1 position but i have not been able to find where it terminates. 

    Unable to find a JDM ecu pinout as well.

    Any help would be appreciated.

    Thanks

  12. Few questions on PDM

    in Razor PDM

    Not sure if this might have been asked before in a thread but I didn't see it as a topic.

    i have a project that we are looking to use the RAZOR. I am looking to run headlights, turn signals, pump, injectors, fan, coils, etc....with the limited high outputs how can i achieve this in one pdm or would i have to add another to the system?

  15. Audi 1.8T Harness Questions

    in G4x

    Posted

    Hi

    I am about to wire up a harness for audi 1.8t and have a couple questions

    1. it seems to only have a cam sensor what would be the trigger setup?

    2. how to i setup VVT solenoid and how does it work as an on/off switch at a particular rpm? i ask as i know it goes on to chain.

    Thanks guys for any input

  17. MSD BlasterSS Coil Settings

    Thanks for the info

    Setup id ATOM on a 4age using 20v igniter and MSD coil.

    My dwell is 4.0ms thru out the range.

    I am experiencing a misfire at 2000rpm and was thinking it might be related to coil, plus i think the injectors or OEM and my be low impedance (will confirm that later).

    I will try the lower dwell values and see if that helps.

    Your trigger 1 is not consistently meeting threshold while cranking - you should try lowering the arming threshold to .2v at 500rpm and 0.5v at 1000 rpm.  If you are still having issues after that please provide a PC datalog of attempting to start and a copy of the current tune.

    car has finally started..........seems it was a combination of things.

    We change igniter and coil plus did the recommended threshold setting and got spark.

    Thanks for all the help

    UPDATE

    we change igniter to 20v 4age with MSD blaster coil, still getting rpm but no spark.

    Can put engine to TDC, run ign#1 test and get spark but when swinging no spark.

    See attached last trigger scope.

    Don't want to recommend COP to customer and there is some issue with the signal out of ECU.

    Any suggestions?

    My understanding is the distributor plugs into the vast module, so I'm unsure how that would come to be unless wiring was messed with. 

    The VAST system interprets or at least reads the crank sensor signal before the ecu sees it, so it may be part of the problem causing some of these trigger signal issues.

    Personally, I would bypass the vast system, wire trigger signals directly to the ecu, and wire in a newer igniter that the ecu can have direct dwell control with (or go coil on plug). 

    I have wire triggers directly to distributor and will try a newer igniter system with a blaster coil but have suggested COP to customer as well.

    Just want to confirm that exisitng ignition system is issue before making purcahse for COP

    VAST module system

    Yes car is still fully OEM

    Did you check and/or adjust that sensor air gap?  You still have the same voltage problem as in the scopes from a week ago, and as KO says it appears you have created another by messing with the wiring.    In your cranking log it only sees an acceptable trigger signal for the first 4 revolutions then when it just slows down a tiny bit you loose trigger 1 probably because the voltage drops below the threshold.  So you should have had a spark for the first couple of seconds of cranking but it loses sync after that so there will be no spark.  

     

     

    I did the gap check and moved them to .2 as suggested.............not sure why the pulse slows down as battery is on charger will i took the logs

    Definitely 24 teeth, the signal is a very low voltage though to the point that I'm not sure even 0.2V arming voltage would work for trigger 1.

    Start by charging your battery as it appears to be pretty shagged and then consider changing your trigger 1 and 2 arming threshold values to 0.2V at 500rpm.

    What would cause that low voltage reading?
