hmm i might try that tomorrow then.

there is ignition timing and additional boost on the nismo - actually not sure about the boost increase.

well i know the arx MUST be tune differently as from factory it runs a few psi extra.. and who knows if nissan advanced abit of timing to compensate for the extra ass...

Getting back to informeter and modifying the signals from these 2 pots, when I made changes to increase opening from 80% to 90%, the informeter would read LESS than 80% (closer to 70% actually) and then the ECU would back off the fuel (cause it thinks I don't have the throttle opened as much as I do) so I would see the injector pulse width drop down (meantime I'm going faster) & of course the knock sensor would put an end to it pinch.gif I'm hoping for better results at the lower end of the spectrum though. There's more fuel at launch and that is where we want the benefit anyway soooo.... we'll wait & see.

seeing as i've got a wideband in maybe me n scott will also figure this one out. but im starting to think it may have something to do with the fuel map as Cihan cant tune the car under 3000rpm when in third, as if he floors it it will kick down to first and jump off the dyno..

so it could also be a possbility that the low end fuel map is muck, as mine does strange things according to the wideband, but once it gets to 3000rpm, ratio sits at about 12v and everything hammers

maybe we could talk Ian into sticking his spare motor on an engine dyno to see if Gihan can tune the emanage to suit! :P

Not that it would really concern Ian or I....but we do like to help when we can.

I think if the transmission has anything to do with it, just an engine dyno wouldnt work i dont think.. Cihan needs to do a track coughroadcough tune from standing still, to full ball in first. Maybe we can get around it with just that(i like to dream)

Now that's a generous offer :thanks: guys.

just food for lhought guys

the voltage range on most tps's is 0-5V

when you hook up an ecutalk display you can configure it to show tps volts or %

but for the % to show correctly you have to calibrate it as WOT isn't actually the max range of the sensor

is there any way to calibrate your display thingos?

and has anyone run the throttle out of the car and seen how far the butterfly is open at 86%?

yeah we already know its a range calibration on the informeter, i mentioned that one page back. at 86% its WOT

thats not the problem. being BTW the ECU retards the throttle to limit torque, we want it back. at almost any cost :P

I reset the Voltage range for the throttle this morning on the the informeter and now see throttle in the 40% bracket when stalling. It was a very brief stall and not completed so this may be a little higher in reality.

I will try to get a proper number later today.

by doing the Throttle position reset or?

is there a way to do it in the informeter??

VQ's have twin TPS signals, 0-5v and 5-0v.

The 36% at stall opening is the big issue, not the 86% once it opens.

Perhaps the issue at stall is just an input to the ecu from the brake. Maybe the nismo has this turned off but for those of us without "awesome", we could just cut the wire....

my thought exactly. i said it earlier but im not too confident in exactly which wire that is.

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • 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
