  1. Hey guys,dp) I finally got my hands onto a wrx4+ link ecu, to put in a 1998 v4 sti Type R (all stock components aside catless DP). I tried to setup an excel file to see where I am at regarding the wiring. For the harness pinout I based myself on the following pictures: Then I used the Help file of PC link to get the ones of the ECU. I have the following questions (Excel file attached): -why are there aux, aux-inj, aux-ign outputs. what are the technical differences between these? -It looks like the list doesn't include grounds and +5v's, are they the same as stock ecu? (sensor ground, shield ground, ign ground, inj ground, maf ground, tps...) -It seems like that in the pin function list I am missing the crank and cam position sensor, are they present? -the pin function list shows An volt 1 for the map sensor, but nothing is lining up to it, and I can't even find the number on the stock ecu. Any idea on that? -why is there 2 times ignition #1 and #2 (ecu pin 4&5 and 17&18)? is that the same output twice or is it really 4 independent ignition outputs to run full sequential ignition? -what is the "Pressure source switching solenoid valve" of the stock wiring harness? Have a nice day! dx4picco ecu pinout.xlsx
  2. Thank you for the answer.
  3. Great thank you for the confirmation. If enough input and output are freed up, is quad avcs possible too on that ecu, or is only intake possible (assuming engine comes from v10 car) ? Have a nice day
  4. Hello dear Link comunity, I own a 1998 (v4) sti type R on which I am looking for a tunable ecu. The link WRX4+ seems to be the indicated ecu to start with. However I have a question regarding avcs control. I am aware that the ej20k in the car has no variable cams timimg, but I planed to swap it for a more recent jdm engine that has avcs. Reading product description here (dealers.linkecu.com/WRX4Plus) It seems the ecu has this option : "Variable Valve Timing (where applicable) Up to 4 channel independent Precision Closed Loop Control 3D Tables with configurable X and Y axis controls Preset or Custom Configuration Supported Engines - 1UZFE VVTi; Subaru AVCS" My question is : is it possible to control avcs with this ecu, and if yes what would be the steps to follow ? Xs loom ? Soldering on the ecu to get the inputs and outputs required ? Directly through pins of the 3 ecu plugs ? Thanks ! Best regards
