very quick question

got mt PFC installed into my R34, ever since then my engine light wont go off the dash :) asked the tuner he said it's running fine etc and has no idea why it wont go away, he said the only time it goes away is when he loads a fresh map onto it but then comes back straight away ?

It's a default setting on the PFC, I think it's to do with the PFC boost controller. You need to go in to the hand controller and turn it off. If you where here I could do it for you, can't remember it off the top of my head. :)

its under settings then sensors the display for on and off in japanese so make it different to the knock setting obviously it might be on atm so just toggle to the other jap character

well it's getting the turbo etc done this week will have a look then :) if not I might pop in one day when im down your way for tafe ?

One thing I am curious about, is whether the PFC has 6 ignition drivers and 6 injector drivers.. or does it run semi sequential? Noticed the VIPEC plug-in board is only 4 drivers and can't find any literature anywhere about the PFC (although one would hope Apexi gave us the full 6).

You will probably find that it is batch injection, i know many ecu's have sequential but from my research when i was looking at getting one years ago the did sequential not many tuners would tune sequential, only batch.

That's it, like he said /\ /\ /\ :)

Hey guys,

Like ian_and1' s engine light being on from key on to key off. After mine has been installed i get TCS, SLIP and tne engine light solid on. and to boot the a/c doesnt turn on. Any ideas? I've reset the data and completed the 30min idle process checked nd double checked the Boost control kit. Any ideas?

Cheers

i like how you say "only"

if TPS isnt working, its a pretty crucial sensor

did the car run OK with the std ecu in? ie did it have the engine check light on with the std ecu?

i cant see why the PFC is pissed off, it cant read the TPS sensor, throttle body sensor

no idea why its not working - the sensor is either shagged or the wiring is mangled or something else is wrong

do you know of any other ER34 PFC users - do they have the same issue?

hmm is THR same as TPS - logic says so, youll probably find the SLIP system expects the TPS signal from the ECU

much like Active LSD does, the PFC wont know/expect this and wont relay the TPS signal to the other computer

so it fails, well at least in my case, thats what was happening

you are best finding another ER34 PFC user and ask what they did at install time

i think Dan666 has used ER34 PFC - ask him

I'm pretty sure that THR relates to a map sensor that only the ER34 has, sounds like yours has failed. This is the same reason we have trouble running the 34 pfc on a stagea because they don't have the sensor at all. If you have a look around the stagea section you can find the exact pin and voltage, its around 4.1v from memory that should be returned at idle.

Hi duncan thanks for the advice. Had a read through a few posts on the stags and theres alot of useful information there. Though I guess theres no real way to diagnose it until i have a known good TPS i can test out..

Any ideas why the A/c turns on but the compressor doesnt? also a/c turns on an off with the console switch in the sensor check on the PFC.

Cheers :D

corrected - What is the "Power FC Pro" and do I need it?

updated - What does the PowerFC look like inside?

added - What does the "FC Pro" sticker mean? Why is it there?

Mythbusters ahoy!

FC Pro sticker means sweet f**k all

it does NOT mean its an FC Pro unit

Hey peeps, I have a problem with my pfc. I have a 33GTR and had the injectors cleaned recently. Before that, not a problem but since, the car wont start cleanly without accelerator input when warm. When cold it started ok for a week or so. But now its the same warm or cold. When cranking the inj duty is between 0 and 3. Not enough to fire it up. Now none of the settings have changed. I have done an init of the pfc and reloaded the tune and made no difference. Once I get it started then no problem at all. It runs spot on. The sensor sw screen shows nothing wrong. I plug the std ecu in and it starts straight away. Any idea's?

    • My take on gg2 48mm, 54mm, 58mm, and 62mm compressor map for same size compressor vs gg1 : All gg2 only outflow gg1 above 20 psi. As all g gen 2 surge line at lower left of comp map move to the right, all gg2 sacrifice spool vs same size gg1, surge line move to the right worst for 54mm gg2. So for same size compressor if you want best response, use gg1, if you want max hp at >20psi use gg2 but you will be laggier vs same size gg1. Max compressor efficiency drops to max 75% on all gg2 vs max 76%-80% of same size gg1. Iirc lower efficiency means hotter iat less dense air so lower hp at same operating point of comp map. Also curious why gg2 is mapped to lower max rpm vs same size gg1 (only 48mm size both gg1 gg2 mapped to same rpm) : 54mm gg1 165,000 rpm  vs  gg2 160,000 rpm. 58mm gg1 150,000 rpm vs gg2 140,000rpm. 62mm gg1 145,000 rpm vs gg2 140,000 rpm. If gg2 can safely spin to gg1 rpm then they can flow a bit more than as mapped. Good thing that all gg 2 interchange compressor and turbine housings with same size gg 1. So gg1 owners can buy gg2 chra only if planning to boost >20psi.
    • My stuff is all with Shannon's, granted, I don't really have imports I'm driving on the road, however, I've had multiple cars at the same time with them. Presently we have the Landcruiser on laid up cover, Sarah's Kluger on full cover, and the house insured. About 18 months ago Sarah wrote her Subaru Liberty GTB off, insured with Shannon's, and the payout, and buy back of the wreck was super quick. In 2020 we had the VF Commodore totalled in a major hailstorm. Storm was on the Saturday, I called on the Sunday and lodged it, vehicle was towed on Tuesday night, assessment team called on Wednesday to say it was a total loss and get payout details, money was in the bank on Thursday morning. Have had a few other claims both at fault, and not at fault, over the years, and never had an issue with them.   Funnily enough, they're also the cheapest insurer I find for things like Sarah's Kluger.   I will say I'm less impressed dealing with them lately around "the experience", as a lot of their staff that you deal with aren't car enthusiasts. Shannon's has a much more main stream feel ever since they decided to become "big corporate", laid a heap of staff off, and then hired a bunch of non enthusiasts. At the same time they've been making a push to be less "call us and we'll personally have someone who cares help" to "hey, this computer can do stuff for you" and are trying to get more square pegs to fit round holes. (That's just the vibe I get from them). Again, have had no issues with claims with them, but get a bit of a "less personal" feel from them.
    • A thing I wasn’t happy with with enthusiast was during the initial phone call they told me they’d insure it for 130k but needed photos.   I then sent them photos and they told me $80k as there were other cars either similar modifications available for around that price, I told them to send me the links to said cars so that I can buy them. i then sent the modification list with prices of the parts (no labor) and the price then came to 115k, which is still shy of the 130 that was agreed in the initial phone call 
    • Ask me a bit later this week before payday
    • I agree that delayed payment probably isn't the most suitable solution. It seems a solid complete transaction would be best. As I wouldn't be using this sale as a line of credit that would typically earn interest, we can probably arrange a much cleaner single transaction deal. I can do $92.52 today. Would you prefer EFT, or Cash on Pickup?  😛
