Hi guys, I received my Power FC AP Engineering computer for my RB20 DET on friday and went straight to the shed to hook it up. Thats all good, it works perfectly with my hand controller showing all the stats. Thats not the prob, I also purchased the optional boost controller kit but I'm having troulble working out where the MAP sensor wire goes (the one with a horizontal and vertical tabs in the connector) sorry guys no pics just yet but hopefully soon. Does this get cut and spliced into the map sensor harness like in paulr33's Power FC FAQ, coz mines only got a 3 pin map sensor connector so i take it i splice the solenoid wires onto the MAP sensor harness??? Any help would be nice guys. Also my car was originally just a GTS so i don't have a factory boost gauge just a aftermarket one with a copper air line any ideas how to hook up the MAP sensor air line??? :ninja:

Cheers guys

if your boost kit has the 3 pin plug and socket

then the 3 wires are for the map sensnor

power, ground,. signal

the 2 wires for the solenoid are run off the factory harness

Hey paul, I've got a printout of the pinouts for an RB20 DET and can't work out where they should go???? Are they just power and ground(earth) from the solenoid? Your photos show you've spliced the solenoid into the MAP sensor plug, do you know if the RB20DET is the same? Sorry if the questions seem stupid, still learning :ninja:

from the top

3 pin boost kit plug

power - map sensor

ground - map sensor

signal - map sensor

2 wires from car loom

power - any 12v power im pretty sure

ground - look for wasteground solenoid control

basically

the map sensor plugs into the FC

and the solenoid runs of the factory harness

on the stock loom is wastegate control

which is power and ground,

ground is switched by the ecu to control boost

you just need to match these up and it works

I'm following you with the setup but my pinout doesn't show a wastegate control pin, should i just get a workshop that tunes the power fc to install the boost kit controller???(Keeping in mind my R32 was originally just a GTS) What do you think paul

Edited by Drift Freak

ok on the gtst loom there is wastegate control

look in the powerfc faq cubes

did an animated gif between differeneces of rb20 and rb25 wiring loom

it shows the wastegate control wires

    • Waaay ahead of ya....(evil laugh!!) Will show the fitment and spec details later when it isnt as rainy !
    • Thanks Dose.....    I appreciate it!!
    • I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.
    • I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.   
    • Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.
