I have trouble with the temp guage (I know its not that accurate) and stupid stock ecu...

on a cold night once the needle reaches the middle... I wait until its been there for a few minutes and try and give it a boot... sometimes it goes nicely all the way to redline but sometimes it hits boost cut... other times it retards the timing...

there is just no way of knowing if the car is really warm enough to boot (looking at the revs on my SAFC at idle is really the only way)

So my dilemma is really the stock ecu and its need to retard my timing or boost cut cos it feels like it... Is there a way around this without going the full ecu replacement...??? and the temp guage is a lying bastard!!! :D

Anyone else have this problem? (note: car runs like a dream on cold nights but only after 20mins of driving)

I'm not sure about your problem but I can help with when is your car ready for a boot!

Basically let it warm up until the oil is warm, and you can tell that by looking at the oil pressure guage, it will be around 4 on idle cold and 2 on idle warm

this makes sense... :)

yeah don't think I have a problem... just the temp guage is a really bad indication of when your engine has enough heat to be safely booted!

that and all the limiters the stock ecu has just annoy me... I would love a PFC or something that would just let me know when it sensed knock and not retard the timing... my ebc warns me when I've exceeded my preset boost limit (usually on cold nights> denser air etc)... but the ecu will just kick into overboost protection making that function on my ebc pointless :mad:

to many things on the car doing the thinking for me :)

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      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

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      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).
