Awesome thread Paul. Well done.

More info than i'll ever need.

Just a thought for anyone with a blown Power FC, that is having probs getting it fixed:

The boys down at 'Access Autoworks' in Vermont, Melbourne (used to be in conjuction with 'Hypertech', who now no longer exist) may be able to help out. Only reason I say this is because i have an ECR33 Power FC currently on its way to Japan to be fixed up. It was blown when trying to install into my R32 GTS-T with RB25 transplant (Jap conversion) and wiring was up the creek.

So if you cant get one fixed, rather than throwing it out, or buying new one, give them a try.

very nice write up. very very handy.

when installing.. do u recommend warming the car up then installing the PFC or just bolting it in and warming it up with the PFC? i ask as does it need to learn its own cold start?

im about to get a 1995 R33 GTST i think they have a Series 2 engine as its a Series 1.5 so is ther a Different PFC for the series 1 and 2?

the car comes with one not installed is ther a way to verify it is the right PFC for the car?

thanks in advanced.

mark.

there is no difference between series 1, 1.5 and series 2 for PFC

33 gtst model suits all. you should warm the car, the install the powerfc and perform the self idle lean procedure (covered in the FAQ)

I plan to install one in my mild modded GTST and run it on base maps for a month or two whilst I save up the cash for a tune. Am I gonna have problems starting it in the mornings and stuff?

I am about to install a 2nd hand PFC... And im not sure if it has a tuned map in it.

If it has a non-stock map will it still perform the self tune setup? is there a way to get it back to base map?

Thanks

thanks paulR33 its a very good read. i read nearly all of it. it doesnt mention to warm car up prior. i just assumed and asked for confirmation.

What type of fuel economy will it be like with the base map? without touching the AFR aswell? just a straight bolt on.?

thanks a bunch

I have a SAFC installed on a standard R33 GTST ECU.

Is the base map on the PFC exactly the same as the standard ECU?

Would it be a problem if I install the PFC and keep the SAFC in the car until i get it tuned?

Is there a way of copying the settings from the tuned SAFC to the PFC.

Maybe by writing all the details from the SAFC on paper and then input these settings on to the PFC.

I do not realy know or the setting options are almost the same between the SAFC and the PFC.

Thanks in advance

fuel economy will be ok ish providing you have a working 02 sensor

no the stock map on the powerfc is not the same as the stock ecu map

it has a bit more tuning and a little bit leaner afrs probably.

when you get the pfc, remove the safc completely (and sell it).

you should not need to run both, nor is it a good idea to.

the safc is simply correction values for 20 load points, its not a complete map so no, the data is not compatible.

i was tempted to order an rb26 powerfc tonight and wire it up to my rb25 and write up a quick howto so for those looking for powerfcs on their r33 could simply follow the steps using a new rb26 PFC but i have some concerns

1) duplexing the afm input to the 2nd afm pin

2) duplexing the 02 sensor input to the 2nd afm pin (if wanted)

3) altering the injector settings to suit rb25 370cc instead of rb26 440cc (so possibly negative correction or latency??)

4) getting a working VCT setup (friend suggested buddy club device $90)

if anyone is willing or interested to work on some of these it coudl be helpful for all

Hey Paul,

Had my FC in for about 4 months now without missing a beat.

Get the occasional orange light pusle on the engine light for the standrad, reaching max levels warning. (no problem)

Today, for the first time, the engine light has lit up but stayed hard on for about 20 secs.

It happenned when coasting down off the throttle, and on another occasionally when sitting on idle.

Idle was fine, revs were fine, everything seemed as normal.

All temps, oil, all good. No other lights.

Anyone encountered this before?

Maybe a faulty sensor? (i hope)

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • 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.
