Ohhhk I'm going to take back my last comment with regard to Haltech Platinum Pros.

This what my tuner (XSpeed) said about the Haltech Platinum Pro...

"Just don't."

I said "please explain" and he said....

It's a universal ecu that isn't tailored for any particular car with all sorts of tuning issues (cost the last guy $1700 in labour alone to get it working 80% of the time lol)

He went on to say that the measuring parameters of the Hally are far too wide to tune one specific street car effectively and would only really be superior if it was for a dedicated track car where normal reliability issues mean jack shit. He said they've tuned every ecu under the sun and the Haltech PP has returned reliability issues with cold starting, idling, hot starting and O2 sensor issues basically all the stuff you need to work 100% for a daily drive.

He seemed to think the AP Engineering Apexi PowerFC for the RB20DET was the beez neez. Easy to tune, designed to work with the rb20det specifically, excellent reliability.

hey guys,

I have just been going through my pfc screens trying to find out whats going on with my o2 sensors and found out they were turned off.

I replaced the sensors and turned it back on but there is another setting (02 sensor reg).

Does this need to be turned on as well.

I have had a look through pfc manual and looks like it may be for the bncr32 and needs to be turned off, but not sure.

The car is a r33 gtr

ok, read whole 40 pages and found this

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

answer found

thanks for the reply , i am going through all the wiring, making sure everything as you say, i will let you know when i get success

the powerfc updates the tune in real time, and then when you key off, commits the changes to NVRAM

in the powerfc FAQ there is a section on this exact issue, search in the FAQ for "ECCS" and youll find a section on how to correctly set it up

on your car, as youve done an engine swap, the ECU isn't given enough time when you power the key off, so it doesnt get enough time to save to NVRAM, thus any change is blown away

the ECCS diagram shows you how it should be setup and how it needs to be wired in

I have a R32 gts-t that is running a Power FC, was tuned almost 2 years ago and haven't had any major problems since.

About a month ago I removed the throttle body to fix a coolant leak and ever since then I am getting a lot of idle hunting and sometimes when coming to a stop the car will stall.

This isn't consistent however, it is mostly ok when cold, but even when hot sometimes it isn't issue.

I have cleaned the AAC valve and have played with the TPS(as this is the only thing I can think of that would have been changed when I removed the TB) which currently sits at 0.4v on idle and doesn't move around.

Any suggestions for settings on the PowerFC I can play with to settle this?

Edited by Kwyjibo

there arent any other than DATA INIT to perform self idle

i can only suggest key to ON but dont start car

check TPS is 0.30ish at idle or adjust to make sure its around 0.30v and floor it and it should peak near 4v

the nissans service manual has what value it sould be at idle as i dont think it should be spot on 0.30v so best to check it

Hi all,

A friend of mine just recently imported a modded R32 from Japan. Its got some extensive mods and looks like it could put out about 400awkw once tuned...

Unfortunately the ECU was replaced and a stock one is in the car now. Just wondering - is the PFC the best option that's not going to cost an arm and leg?

Other options explored was Motec (too expensive) Haltech (not sure), Link ECU (again dont know anything about them) Nistune, etc...

If there are any con's with the power fc, what will it be?

any feedback much appreciated!

Edited by ironpaw

go read the powerfc faq, it has everything covered already

no known issues with using a powerfc on that car

ask who ever is going to tune it what ECU they prefer

no point going to someone who only tunes vipec's with a powerfc and vice versa

hi guys,

got an issue with my pfc. its at the tuners at the moment and he cant get it to rev past about 6100rpm. he said he has all the different rev limit settings set at 8k and he also swapped the pfc out for the stock computer and then the car revved fine so obviously somethings going wrong with the pfc.

any ideas?

pete at jaustech. he said hes spoken to a few people about it and no-one has a clue why its doing it. rekon it might be a faulty pfc.

hes sent an email and is waiting to hear back from apexi about it

i assume so. he said hes saved the map so if i did have to get another pfc he could load it straight on.

thanks for the offer steve, ill wait to he back from him again about it anyway.

did a search but cant find any thing, im thinking about getting a map sensor to hook up to display boost and peak hold on the hand controller, just wondering if it is possible to hook up a solenoid for boost control, if so any idea's what wires go to the solenoid?

normally its sold in a kit as the PFC boost kit

i have the solenoid i cant remember if i have 100% of the wiring but i don't have the map sensor, was all bought 2nd hand

i since bought a AVCR for electronic boost control

Yeah I know, but all I wanted was the map sensor to display boost, with the wiring you cab get that for $50+pp from the states, then I started wondering if I could hook up my current boost controller solenoid to it and have it work, the solenoid may not work but if know what wire to hook up to it then its worth a try

    • I'm hoping I just don't have to do an engine rebuild NOW. Doesn't mean I won't do it at some point. I think a plus point is that the car presumably ran on or close to stock power nearly all it's life so far. Only the Owner I bought it from actually increased power with a standalone ECU and blew the OEM turbos. And after it got thee 2860s it wasn't driven an awful lot either.   That is what I meant. With the twins coming on so late (4500-5000rpm) I hope the rods won't want to exit the block prematurely. And it still being a 26 means the torque curve isn't gonna hike up all that much.   It didn't blow up on the dyno when they tuned it to 500ish crank. So I suppose it'll be okay for now. They did put a Tomei head gasket on first though which did not seal at all, and they redid it with a Cometic one. Which I hope won't be my water leak.   Mainly anything oil. So far all it has is the N1 pump, oil restrictor and a filter relocation kit with a cooler.
    • 15000? ish? Something like that anyway. It wasn;t so much a wear as a tear that then spread. Might have lasted a lot longer if not bothered by just one incident, whatever it was. I took a punt. They are really comfortable and do a good job of holding. My daughter HATED it when I first put them in, and probably still does now. She has sensory issues and hates the way they are all up your business. I'm 197cm and 95kg. Not fat or particularly wide, and the XL size seat is the rigth fit. If I was any fatter it would start to get too snug. Any skinnier and you'd possibly want the smaller width.
    • Mrs rs focus came factory with recaro cs  sportsters in it and they a pain in the ass to get in and out of with the really high bolsters, once you were in them they were one of the most comfortable seats I have ever sat in
    • The NA 2.5 has very little torque. You won't feel much. Those trannies are also a million years old now and it could well be f**ked. First generation electronically controlled autos will often refuse to kick down, ete, etc, depending on what's wrong with them.
    • Yes, but no but yes but no. Those "it's fine up to 500HP" rules and everything else like it were all determined back when the cars were 10 years old. As they are now 30 years old.....what do you reckon the chances of something shitting the bed are? I'd say they are much higher now than they used to be. You might be lucky. You might be unlucky. Spin the wheel and find out. Yeah, nah. It's actually exactly the opposite. Making boost early and having heaps of torque able to be generated right in the middle of the rev range will do more to damage an engine than having to rev it high to make the power. Think about the load on the conrods, bearings, etc, to make 400HP at 4000 rpm, vs 400 HP at 6500 rpm. So someone has already "let the Nissan out" which is how we describe the increased chance of a fiddled with engine to have had something done wrongly. Many more engines that have been opened die than stock ones do - even if you into consideration how they are treated wrt power levels and the like. Again, not saying that yours will definitely have been put back together by a moron. But the possibility does exist. It's still a lottery. Spin the wheel. What weakspots?
