Pojebany Posted November 28, 2023 Report Share Posted November 28, 2023 Hello All! Thank you for providing Forum support first of all I am trying to upgrade my ECU in my S14.5 (pic attached) with a Redtop S13 SR20. Here is my current setup: Rs enthalpy on 93 (15psi) Z32 MAF wiring specialties pro harness w/grounding kit top feed radium fuel rail radium fpr deatschwerks injectors oem arrett t28 turbo isr tubular manifold isr turbo outlet isr downpipe hks catback greddy bov aem wideband greddy fmic ARP Head Studs I have a Link Monsoon G4x, and sadly I am behind in ECU knowledge and trying to grasp my head on things. My question to you all is this. With my wiring specialties pro harness do I need to buy a whole medium sized loom to go through the chassis, or can I work off the wiring specialties harness? I also understand what basic sensors I need, and what AUX and Digital Outputs I need. However, I am confused on what sensors I can reuse on my SR20 and which I need to buy to feed into the loom? I am also confused on where to buy these sensors and how I can verify they'd be correct for my setup? Thanks again, for any or all input!

If the internal map on the monsoon was being used you may have to wire in a new one which is fairly simple as well. Do you happen to have a copy of the pinout from the WS harness? As far as sensor's go everything you have would work just fine, maybe an IAT in the charge pipe just before the throttle body, a fuel pressure and oil pressure sensor, bosch flat response knock sensor would be highly recommended as well. If you need help with wiring I can help you out completely. Hello, thank you or your feedback! That seems promising that this may be a bit easier than I imagined. I believe I have found the WS Harness Pinout (see attached) I am 64-Pin, as s13 Redtop SR20 is 64-Pin I am also looking to purchase this 64-pin plug, that I am attaching. Is this what I am looking for? https://www.wiringspecialties.com/sr20dets131.html S13 S14 S15 SR20DET Pro Harness Install Guide.pdf Quote Link to comment Share on other sites More sharing options...

Similar to a Nistune "daughterboard" installation and re-flash. Assuming the factory ECU loom still exists - you could replace the factory Nissan flashed "RS-Enthalpy" ECU directly with a Link G4X Plugin https://dealers.linkecu.com/NS15X_2?quantity=1 9 hours ago, Pojebany said: I am 64-Pin, as s13 Redtop SR20 is 64-Pin I am also looking to purchase this 64-pin plug, that I am attaching. Or if the Monsoon G4X has already been purchased, either make a patch loom to go from Nissan ECU Header -> Monsoon with: Wiring Specialties 64pin kit: https://www.wiringspecialties.com/sr20dets131.html and Link 'A Loom short' https://dealers.linkecu.com/0LA_?quantity=1 Or cut the Nissan ECU header off at the end, and terminate directly into a Link 'A Loom short' for the Monsoon G4X Quote Link to comment Share on other sites More sharing options...
