Howdy, i have a power fc djetro for a s15 sr20det. all is well and good apart from one thing, i cannot read japanese and the whole manual is in jap!

is there a diagram on pin outs for the IAT wiring around anywhere?

any help appreciated

hi

the powerfc is modelled exactly of the std ecu for your car, that is, the pinouts match exactly, thats why its plug and play

so if you can find the pinout diagram for s15 SR20 then thats the same as the powerfc pin out

the powerfc S15 SR20det djetro will use the same AIT wire as the stock ecu on SR20 S15 ecu

Not sure if this is silly question, but what exactly is the base map (been messing around with an RB26 D-Jetro)

I have only ever really messed with RB25 Power FC's and have never seen the base map before.

Having trouble getting it to start, but it idles fine once its running so just wondering if the Base map might be the issue. Played with the Cranking ms etc and still doesnt want to start.

Hello,

Maybe I missed something or didn't search hard enough so please don't burn me.

I was looking around the market for a PFC for the HCR32 RB20det and can't find them anywhere. I've found alot of people saying that one was either discontinued or it was specially made from another company or something. I just wanted to know if the R33 RB25DET PFC/Controller would work on my Rb20?

I'm sure someone has already brought this up, but I guess my searching skills are not up to par :(

Nvm I found the answer. I just need to search better. :D

G'day all,

Can anyone with a R32 or R33 GTR running D-Jetro PFC help me out with their FC-Commander readings? Paul maybe you have come across this info in your years of PFC guru'ness?

Just want to know if (on rb26 d-jetro PFC):

1. the front map sensor is PIM1 and rear is PIM2, and

2. the front O2 sensor is O2-1 and rear is O2-2?

Easy to check, just disconnect the front one, switch ignition to on and then check sensors under ETC... should read 0.0v (ish) for the disconnected one.

Can check the O2 sensor as well by running car until it goes closed loop, switch off O2 feedback then disconnect front O2 sensor in engine bay. Check the sensors display and the disconnected one will read 0.04V (ish).

I have checked the ECU pinouts and wiring diagrams, and mine are wired in the right way (did pin to pin checks)... BUT on the FC-Commander display it shows that PIM2 is front map sensor and O2-2 is front O2 sensor. That would appear to be back to front?

Anyone who can spare the time to check theirs and post up their findings would be heaps appreciated. Can't find this info anywhere.

Cheers

I've been searching the web for an answer to this for a week, didnt find one in this thread either... Anyone that actually know?

Think I might have mixed up my front and rear O2 sensor, but since I cant find anything about them I can only confirm which one is 1 and 2.

Got the regular (non d-jetro) PFC

Thanks in advance.

I'm not sure either, but since my wideband lambda says the car is running rich again (and I recently replaced the O2 sensors) I can't ignore the "what if" the front O2 sensor affects the 3 front injectors and same for the rear?

The front sensor reports the engine running lean (0.0V most of the time, jumps up to about 0.5V when I press the throttle and acceleration enrichment comes to play) and the rear one says it's running rich (about 0.8V most of the time).

O2 feedback is enabled, and O2 sensor reg is disabled. From what I understand the O2 reg setting is for compatibility with the older 12mm thread sensors, and I got the 18mm "new" sensors in my downpipes.

This leaves me with 2 options as far as I can see:

1. The front O2 sensor broke down after 1 week and about 200km driving

2. Something happened to the injector controller and one of the front injectors isn't opening as it should.

I've switched the 3 front and rear injectors to rule them out.

Thanks for your time, and you deserv a mental high five for your homepage!

EDIT on above:

Found the pinout, pin 29, front oxygen sensor, is the square one, called O2-1 in the PFC. Took my time to measure on the car.

Now I will try and switch the sensors around to rule out ECU breakdown before I send my new sensor back to australia...

My fc edit is not working anyone have software or solutions its saying rb25t1-d version 8.00 is not yet supported

hi, you would need to ask fc datalogit people to update their version of FC EDIt. I think you have the newly released RB25 Djetro which is not supported by FC Edit and the datalogit guys probably dont know about it yet

Hello. The website that hosts this FAQ has been closed as I got sick of it being hacked by Wordpress exploits which means the link in the first post won’t work.

I can add up a PDF copy of this document if you want as I haven’t added any new content for a number of years now. 

Please advise

@paulr33 Can I get a copy of that PDF. Was not expecting the site to ever get removed. It would help immensely.

Anyone who wants to check the website can use "wayback machine". I found a lot of the information very helpfull, it'd be a real shame if the information gets lost.

Good looks man. That worked for me.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
