Hi I bought my Ceffy (RB25) with a plug-in Wolf 3D V4 installed. It's running on base maps atm...

Have heard alot of negative comments about this ecu. What makes them worse than Microtech/EMS/Haltech etc?

The car will be track dedicated for the moment.. Should I be looking at a more street friendly ecu if I plan on rego-ing it later on?

Edit: Running a HKS TO4e kit, stock head/cams, Splitfire coil packs, Suspected Z32 AFM and larger injectors :

it comes down to what your tuner can tune. all ecu's have their pro's and con's. some are easier to tune than others. power fc is probably the most common ecu on skylines, but this doesn't mean its the best. from what i have seen it is one the most limited of them, as it can't run auto's very well. it also requires you to retain the air flow meter.

the power fc is also used for the 'wank' factor. people can set things themselves and show off to their mates. but as soon as paulr33 reads this thread he will recommend the power fc over anything else.

but as i said to start off with, talk to your tuner. if there is no one within a 3 hour drive that tunes a power fc it would be a really dumb idea to get one. if your local tuner can tune wolf then keep it. if they tune haltech, then sell it and get a haltech.

steer clear of george mays. your best option is to drive to someone who 1. has a dyno, and 2. has experience with your engine and that computer. I have had my own personal experience with george and will say I was extremely dissappointed with the results. I ended up paying alot of money for nothing really.

I ended up taking the car to redcliff dyno where they looked at the tuning and laughed and showed me how dodgy it was, and they arent even wolf distributers! they tuned it up really well and treat any car like their own.

just my experiences with george mays.

Too true. The main difference between an ECU that runs solely on the MAP sensor & one that uses the MAF (Actually Power FC uses a combination of MAF & MAP, so this is a fairly gross over simplification on my part) is that getting an engine to run well at idle & low TPS measurements is much easier using airflow meters than manifold pressure. The tune should get done quicker & be cheaper.

An amazingly inept comment. Can you name a PNP ECU that will run both the motor & the auto trannie? Not the Power FC, but then no one with any sense would recommend and ECU install like that simply because it will destroy your transmission in pretty short order.

:) People can also quite easily run data loggers, ensure that they are not running too much ignition advance use the peak/hold function on the display etc etc etc.

Unless you are continuously modding your engine, you should only need a tune done once. Get it done properly.

There is nothing inherently wrong with the Wolf.

it also requires you to retain the air flow meter.

that is the stupidest shit ive read today

power fc … what i have seen it is one the most limited of them, as it can't run auto's.

Since everyone else is ripping into you I might as well have go. Kick you while you are down to make sure you don’t get up. :)

I have yet to find an ECU of any BRAND at any PRICE that has the ignition cut and retard logic programming for the Nissan auto. It requires extensive (expensive) programming and no aftermarket ECU manufacturer has been able to justify the cost.

:D cheers :laugh:

PS, yes I have driven a Wolf with an auto and it was shit, rough changes, flaring, slippage etc etc all the things you would expect to encounter without the ignition cut/interrupt and retard programs.

how do you mean? Normal Power FC's use AFM, there is a version that uses a MAP sensor, but they don't use both.

Wolf3d v4 for example can run either MAP or AFM or TPS, or a combination of two of the above.

What I mean is that the inputs to the Power FC (Not the Jetro version) include both the manifold pressure (This is the y axis on the maps) as well as inputs from the AFM's. So the system actually uses both. Most ECU's are more reliant on the MAP high up in the rev/load area of the maps than on the AFM's.

Hope that makes sense.

My wifes car runs a version 4 plus plug in wolf and it is great.

it is very tuneable, it has maps for both ignition and fuel at every 125 rpm and 8 or 9 load maps.

Can run extra injectors as it has it's own microfueller, as a really easy to use laptop program for tuning and setting up, and all the manuals and so on are downloadable in PDF form of the website.

And my wifes car was an auto and it ran fine with the wolf, as a plug in they work ok with the auto, but a wire in needs some work to make the auto computer talk to the wolf.

Thanks everyone for the input..I'm a newb to the engine management side of things so this is a little over whelming lol.

So there should be no idle problems on a manual RB25 with an experienced Wolf tuner?

What does 'Wide band AFR' mean?

Wideband AFR means on the hand controller screen you get real time air/fuel ratio read out.....but you do need a specific wide band oxy sensor.

Idle is fine....the plug in wolf should use the original IAC to do the idle control.

The wolf has pretty much all the maps a motec has with about 1/10 of refineness. They have all the maps in there and some of them work some of them dont. I've tuned two cars with wolf(and thats as many as I ever want to) one was a plugin for a r33 that was fairly standard all the usual mods - exhaust, FMIC, boost control etc. I found that it controlled the idle quite nicely it also seemed that the timing control was quite precise and the fueling was fairly consitent and tunable.

My second expereince was a GTIR pulsar plugin running a gt28 BB turbo, 440cc GTR Inj exhaust, FMIC blah blah balh. The idle control didn't work, the phase angle of the timing was incorrect (minimum timing number was 22 degs - its not likely that you need less than 22deg in a turbo SR20 is it!!!) and the angle couldn't be retarded. Contacted wolf - whats wrong standard ECU idles fine with the timing in the correct spot put plugin wolf in and timing is wrong. THey are still addiment that there phase angles are correct. Now the car had 750cc inj to begin with which where absolutely impossible to tune down low so we replaced them with 440cc inj and it made it just bearable.

The thing I noticed which said it all to me was that when change from 250rpm increments to 125rpm increments and making no changes it then ironed out certain fueling bumps during a WOT ramp - what the??? This indicates that there interpolation between cells is just shithouse which I think is one of the biggest problems thats why you need 600000000 cells to tune a WOLF.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
