Hi all was supposed to get my pfc tuned today but found out it was not really working.

according to Paul @ chasers he was able to communicate with the pfc

the problem however, was that the voltage coming out from the pfc (to cranksensor etc.) was too low (way below 12v)

the car wont start with the pfc connected and so they checked the wires and stuff everything seemed to be good

and so they swapped the stock ecu back on and started the car without any problems

so does anyone no where shuld i go?

check in the fuse panel on ECR33

drivers side in the cabin

look for ENGINE 10 AMP fuse

check if its blown, if so reclace it

i forget which one is ENGINE 10amp

so check them all

or find a diagram of it my site

paulr33.com

yeh what paul said is correct, and most likely there is nothing wrong with your pfc...

i'm gonna take a stab and say you had a z32 or similar installed recently?... if so theres a good chance the signal wire shorted to ground causing one of the 10A engine control fuses under the drivers side dash to blow... this will give you approx 6-8V output instead of 12V and cause relays to click and the car not to start on the PFC .... however for some strange reason the problem does not affect the standard computer!

so check all the engine control 10A fuses under the dash on the drivers side!

good to hear all sorted

yeah its something thats got me gobsmacked

and we've seen it before, the illusive missing 10amp fuse

i dont get

how ECR33 with standard ECU runs fine and no problems for 10+ years

go and install the PowerFC and it goes spazzo, only to find a MISSING 10amp FUSE

i mean, i get it if was blown right, but a MISSING fuse - that makes no sense?

if its part of the 10AMP engine control, how can it be missing and work with the stock ecu?

why does the powerfc need it? what circuit is broken by this fuse MISSING ????

it make ZERO sense

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
