Well i finally got a pre-tuned chip from Toshi, basically had the fuel/boost limiter and speed limiter removed.

Here are the results, i kept things pretty tame with only 10deg advanced base timing with adj pulleys set at 2deg advanced inlet and 3deg retard on exhaust.

I think i really need to invest in a PFC to straighten out my A/F ratio and get a better power curve.

let me know what you think.

I set the ign timing really low for two reasons.

1. i have a shit timing light i cant really trust, and didnt have time to get it sorted before the dyno.

2. i wanted it to be super conservative because i plan on taking it to WSID a few times.

I will hit the dyno again and try smooth out the midrange A/F ratio with the SAFC and maybe give it a tad more timing, just so it creeps over the magical 300rwhp mark :D

I didnt get to play with my adj pulleys unfortunately. just on the setting i listed above, so i dont know the exact difference they made.

These were on my stock injectors with 2530, the first pretuned chip with high fuel pressure saw the A/F ratio up top below 10! so they can flow a fair bit.

yeah its a bloody rocket! i love it, it pulls harder than alot of GTR's i have driven so im very pleased :)

i wonder what time ill get at WSID. i really want to get into the 12's but i think i might be dreaming a little on street tyres.

but i have some soft suspension that should help.

Hi bbenny

My chip is not only fuel/boost limiter and speed limiter removed.

Its changed

HIGT octane Fuel map.

HIGT octane Ignition time map

Fuel/Ignition timing TP scale

Some cars TTP MAX

Remove speed Rev Boost Limit

With about 4000rpm the increase is 50hp thsn std ECU.

Top end about 30HP increse.

This chip is basically for all R32 mods 044 fuel pump amd GT2530 turbo .

Price only $200 inc mods ECU and chip.

If I go to dyno with you I be able to make better map for your car .

Please give me e-mail

Im sure yours should be sweet, you have all the bits on you need.

I need a PFC to straighten out my A/F ratio and should see a better curve, might give a little more timing too just so i can say i have over 300rwhp hehe

Evan, giv ethe guys at Unigroup a call and see if they will have a play with the Wolf.They have tuned a range of ecus, and when i spoke to them about 6 months ago they hadnt tried the W0lf ver 4, but were confident it woudl be easier/better to setup then Micxrotech

      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.

      By Gantai · Posted

      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).
