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,.

    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
