the airtemp sensor for the djetro kit is an optional part for some cars that done have a factory airtemp sensor

greenline have the part # on their website - check it out

you should use this on the 26 detro PFC and connect it to whatever the airtemp sensor wire is on the RB26 loom

as this will allow airtemp correction for intake temps, the sensor should be either in the plenum, throttle body piping or just after the intercooler

if it was me, i would put it just after the intercooler

for the twin map sensors im pretty sure you splice them into the AFM signal inputs on the RB26 loom

check the specific djetro manual and make sure you get it right, if you get it wrong you face shoritng out everything (throw it in the bin)

you can splice up the output from the map sensor and run it into both map sensor inputs on the RB26 loom to the PFC so both PIM-1 and PIM-2 have the same value

i would only see a need to run one map sensor on the Rb25 engine as i think the Rb26 uses twin map sensors as it previoulsy had twin afms so it was possibly to hard for apexi to recode the complete logic to suit 1 map sensor and because its got individual throttle bodies so it runs an average across both map sensors to get a more accurate reading, you shouldnt have this issue on rb25 as there is only one throttle body

the 02 sensor as its a RB26 PFC will expect R32/R33 GTR style sensor as you have GTST it wont work correctly

youll either need to run without 02 feedback completely or change your 02 sensor to the GTR style 02 sensor

if you go for NGK BNR32 style 02 sensor you can set "02 registered" in function select to run in BNR32 mode

otherwise get a GTR33 sensor and leave 02 reg off but have 02 feedback on and it should be ok as long as you have the same GTR33 sensor

you can splice up the output from the 02 sensor and run it into both 02 sensor inputs on the RB26 loom to the PFC so both 02-1 and 02-2 have the same value

thanks mate. Is there any bad side effects of running no 02 sensor with a djetro? Or would it be worth buying a gtr32 one?

hello i have a 95 nissan 240sx S14 the US version of the S14 silvia and i have recently installed a R34 NEO engine in it and i am running it witha power FC . i have since got it up and running and i am now in the tuning stages but i have unfortuantely stumled across another hurdle. in the snesor check function i have a highlighted sensor which i believe is for the traction control system. its labeld as THRM and its reading 5.11 volts...i nologer am running the factory intake plenum nor the factory throttel body i have installed a greddy plenum and a Q45 throttle body...if this is for the traction control system is there a way i can fool the Power FC to make the sensor light go away so i can finish tuning it and get it running the way i like it...please help me out guys...i am keeping my fingers crosses on this one...

thanks in advance

hi

this is also a question im intested in, i have also removed my tcs throttle body setup, now running greddy plenum ect. but now i need to fool the power fc somehow, or turn the feature off completly. is ther a way to do this through the hand controller?

thanks for the help...in advance and great thread.

i have replied to your pm - let us know when you find an answer ill add it to the FAQ

  • 2 weeks later...

and here is another question...

i put in my Power FC this arvo and followed the great manual that paulr33 has wrote... i put it in, did all of the idle instructions and then came time for a test drive... all went fine...

i jumped in the car about an hour later to go 2 ice hockey @ boondall and it gets there no worries (idles perfectly and response is good) but then it came time to leave and the engine check light came on... wasnt sure what to think at first... so i went to the sensor check page in the hand controller and discover the "THRO" sensor is reading 0V... thing is, drive for 200m and it goes away and a reading of approx. 0.5V is there... go around a corner and the light comes back on... drive a little bit more and away she goes... does anybody know why this is? only thing i could put it down to is either a dodgy sensor or shitty wiring sumwhere...

any ideas?

thanks in advance...

hmmm...

just got back from tafe... started the car and its idling high (1,350-1,400 rpm). im sitting there at the traffic lights waiting and the "check engine" light is on (yes the same sensor "THRO" - throttle is reading 0.00V) i sit there a little more and it goes away (THRO reading 0.43V and rpm down to 850-900) i drive away and no more then 1km up the road the light comes back on... 0.00V again... i stop at the next set of lights and reving high again...

when i take off with the throttle reading @ 0.00V the car doesnt feel right... when i take off with the throttle reading MORE then 0.00V i couldnt ask for anything better...

anyone else experienced this problem? ill probably put the sock ECU back in tmrw morning b4 i leave for tafe again unless anyone can diagnose what it could be...?

the throttle position sensor is loose or faulty

its going to 0.00v which is out of range, which is why the revs jump to 1500rpm and why the engine check light comes on

oh ok...

y have i never had this problem before with the stock ecu?

driving home from tafe 2day, i didnt see the engine light once (throttle sensor -> +-0.36V) but the car kept hunting... 800 jump to 1,400 drop to 800 jump to 1,400 and so on...

ive read the "My idle is really crappy and it hunts around a lot when on idle. What can I do?" in the FAQ, but why didnt any of these problems show up when i first connected the Power FC?

unplug the PFC and replug it back in - be sure you securely fasten it and its not loose

a lot of install problems come from the user not plugging in the harness plug correctly so some of the pins dont connect properly or they come loose easily with car movement etc

lol very true - I had a heap of wierd stalling problems once and stuffed around with everything under the bonnet, battery etc etc.

turned out to be the harness plug was not in straight and didn't tighten down properly. when I undid it and reset it was perfect

hey,

i am after the rb26 intake temp sensor. I rang nissan and he said they dont have them. I rang back and said it should be near the plenum (am i right?) and he said there is a sensor on the plenum and it is called a "Engine coolant temp sensor" and it screws into the plenum. Nissan part number is 22630. Cost is $96.

Does that sound right or is it a different part? I have searched all over this site, cannot find a part number anywhere. I emailed greenline too cause i couldnt find it on their site and they said they dont have them, nor do they stock OEM parts... so im confused.

cheers

ok guys im still fairly new so hoping to get some help

i have a 95 r33 with 2530, fmic, 3" zorst, pod filter and power fc.

now i had it tuned 3 weeks ago no probs it ran fine only prob is that i am getting no more than 250km to a full tank?!?!

also can smell how rich it is running!

now i paid top $$$ for my tune and dont wish to fork out again because the made an error.

also the INJ setting is set to 130% across all 6 injectors is that safe? have only been driving very light load as it is daily

car and would like best economy but 24L/100km isnt right at light load is it??

hi shane

fuel economy and complete tune issues are covered in the faq - have a look at the top for the document index

it covers the issues you are having with poor fuel economy.

what injectors do you have? do you have stock ones? i see no need for %130 correct on std injectors

maybe the tuner had some alternate strategy but most tuners dont touch injector correction unless larger injectors are fitted

    • I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...
    • Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
    • Oh, and as for everyone with their fuel economy changes, I switch between E10 and 98 in the company car. Even do when I had personal cars that could run on E10. You know what changed my fuel economy in any noticeable way? How I drove, and where I drove. Otherwise, say on full tanks of just back and forth from work only (So same trips, same sort of traffic), couldn't notice a difference that I can correlate to the type of fuel in use. In the current vehicle, that's over 42L of USABLE fuel. While 98 is all "more energy dense", it also has higher knock resistance as it takes more energy to get it to ignite too. The longer hydrocarbons, typically more tightly bound. So running the same ignition map, can also produce less power, if there isn't enough time to get it all burnt through properly, as yep, the flame propagation speed is different from lower octane fuel to higher (Higher has a lower flame propagation, due to the more tightly bound and harder to self ignite funs. This is also typically where, a vehicle that is designed purely to run on 91 (Whether it be E10 or normal 91) usually sees absolutely no real world difference in fuel economy for the normal man, woman, or dog.
    • We've got some servos around me that have 91 with E10, 91 (no E10), 95, and 98. At those stations the change from 91 E10 to 91, is typically around 8c/L.   But lets not get started on the price of fuel in Oz. It's ridiculous. All the service stations around me, bar one, the price of fuel has been over the $2 mark per litre for the cheapest, 98 being around $2.45. That one service station is a CostCo, fuel from it comes from the same refineries, and makes no pitstops, it runs great, including the 98. In fact, I've had no issues on CostCo fuel, but plenty of issues at other stations!. The CostCo fuel, was $1.65 roughly this week for 94 with E10. $1.88 for 98. Servos directly across from it, $2.10 for 91 E10, and $2.48 for 98. The part I had to laugh at? If I drive multiple HOURS away from Brisbane, say out near Nanango, or Kingaroy, or even out to Goondiwindi, the price of their fuel, is the same as what it is at the CostCo... Oh, and that BP servo at Goondiwindi is HUGE and goes through epic turnover of fuel, so it's not sitting there for weeks going to shit. And what blows me away, my mate is one of the people who drives the Fuel Tanker all around QLD, delivering to all those places. At the same company his previous role was doing the "local haul" deliveries... Same truck, same driver, same pickup point it all comes from. So you tell me, how the hell it is 60c/L CHEAPER for fuel, when nearly all else is equal, except they require a B-Double to drive half a day out of Brisbane, and half a day back, every second day, compared to the delivery that can be under 30 minutes drive from the fuel pickup point... Not to mention, go five blocks down the road, and Ampol to Ampol will vary 30c/L... And I've had this conversation with my mate... The way it's priced, is just typical, pure and utter rubbish... He also does runs from Brisbane, to all over QLD, down to Newcastle, Sydney, Nowra, Melbourne, Geelong, and even out to parts of the NT depending on the companies needs. His main stuff is all the longer distance away from home for a few days at a time, then when he's back, he loves to just pickup extra shifts wherever he can in whichever truck, hence all the weird different places.   Oh, as for getting E10 into all the fuels in Australia... It was very quickly highlighted, that we don't have enough biomass available to use to make E10 sustainably like they require, and it would dramatically cut into our, and the worlds food chain supply...   I vote we all just start running on liquid methane gas... Plenty of that just getting tapped off at tips from underground decay... (Note, this is pure just stupid commenting. I could very easily highlight the reasons its not a good idea especially on scale...)
    • Am I correct in assuming that the R35's are getting the classic skyline haircut off the odometer?  Quick search on carsales, there are 33 08 and 09 GTR's for sale, only 2 of them have more then 100,000km's on them (116,075 and 110,000 respectively).  And somehow there are about 25 for sale with around 60,000kms? Looks like the classic skyline haircut to me =/
