contact whistla on these forums, he's in VIC too and got his Wolf 3d installed in his R33. I think his was manual tho. Work was done by some rotary workshop from memory.

i have a wolf plug in in my auto r33 the only thing thats wrong with it is gear changing from 1st to 2nd is pretty hard and it holds gears longer i had mine supplied and fitted by peter at rank rotary in mentone ph 95851906

That seems to be the problem with aftermarket ecu's in autos, the gearchange quality suffers. That's why I am going with the less than perfect solution of an SAFC. :)

gear change isnt a problem as long as you bridge across the plug for both the 3/4 throttle position (kickdown) and the TP sensor for shift points. These inputs go into the original ECU, then back out to go to the PCM.

Mine changes beautifully....

Hi i dont spose you have any pics of the plug that has to be bridged? did you do yours yourself?

its the plug at the ecu, you just have to bridge some pins at the plug.

I have all the diagrams somewhere, ill have a look tomorrow and let you know, what i have here is the signals go from pins 38 and 57, i think they go to pins 14 and 5, but ill have to look at mine to be sure and see which one goes where.

a mate of mine is selling a brand new plug in wolf with warranty etc all brand new in the box never used for 1300 i dunno what thats like price wise but it sounds ok to me..... if u are at all intrested it may save ya some cash... cheers Jon

That's the price you buy it from the "retailer", no savings there.

I too have a wolf 3D, my car is a manual. Also tuned at Rank Rotary, with some finner idle adjustments done at EAS Performance.

i didnt get around to it today, but the easiest way to do it, the way i did, is the check pins 14 and 5 with the nissan ecu connected, see what voltages they have coming out (use a digital multimeter, NOT analogue). one should have a voltage that increases from around 0 volts closed throttle to around 5 volts WOT. This pin is the sensor signal OUT to the PCM. Once you have found it, and you have your new computer ready to plug in, simply run a bridging wire from pin 38 to the one that showed the variable voltage.

Without this feed from the TPS, the PCM has no idea of throttle position, so upchanges and down changes will be erratic, AND, line pressure could also be low, which could cause slippage in the clucth packs and bands.

I think from memory that the 3/4 postion throttle switch also goes out to the PCM, for kickdown, but i'll have to check mine to be sure.

I'm not running the wolf, im running a motec m48, but obviously the principal is the same.

Hope this helps.

This wiring diagram is one of the best i could find, its large, (1.2 mb jpg) but very clear.

If you can, print it out on A3,.

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
