Wolf 3D v4 ECU

[Kichigai]

Anyone heard of this computer? I heard its a plug and play but I haven't heard much else. Like to hear from anyone that has one and if its any good.

Thanks

Hey dude,

I have been looking into this unit myself and it seems to be a very decent piece of kit, at a very attractive price point too!

They have released plug-in versions for popular cars such as 'S' series nissans, R33's, WRX's etc. These are a full replacement ECU that can be tuned by a optional hand controller or laptop with appropriate software. The good thing about having the hand controller is that it can display all sorts of info about the car.

Check out www.wolfems.com.au for more.

i had wolfs on 3 of my rotary cars 2d 3d V2 & V3 and helped my friends with his new 3d version 4.

An explaination of why you dont like it (version 4, not 3.) would be appreciated.

A friend got me to look into it. Mat, you know this guy (B REAL). Anyway, apparently its a good price and fully 3D mapping whereas the Apexi PFC is only 2D.

Is there any truth in this? If so, does it make it any better. Interested in your comments too Got Boost.

Thanks

Nothing against Formaz Got Boost, but their name since changing ownership has not been the best.

I would be interested in seeing why they do not like the V4...more tuning resolution, faster processor etc, surely that would make it a better product. Maybe they don't like the laptop interface???

I am definitely going for the Wolf V4 plug & play for the R32 GTR.

As you know, I got to know the PFC very well on my old S15. The unit has some great pros, however one of the biggest cons was that there is no temperature correction.

Detonation was much more evident during the summer months and during the day. As you only have the choice of only one set of "custom" maps or the factory (default) maps, this means that you either run a conservative map in the cold weather, or have to spend a fair bit of time remapping for summer/daytime performance runs.

The PFC also uses MAF (airflowmeter) rather than MAP. This is not really a problem in terms of flow restrictions as you can bolt on a big Z32 meter (or a pair of the suckers for an RB26). Don't know which option I will use for the GTR as I have heard that the 6 throttle bodies don't give a stable MAP reading.

So I take it you have heard favourable things from Steve then Gav? Good to see that the R will not be staying stock for too long hehe.

Hope all is well.

Yep - he knows his Wolf systems pretty well and is bloody patient when it comes to ironing out "gremlins" when tuning.

Guess I'm biased towards Grant/Steve after the huge effort that they put in on the S15 and they didn't even supply the ECU.

There should be a few Version 4 installations running around now and I will be speaking to some of the guys that have gone this route.

BTW - Jash has landed that blue V-Spec. Drop by there and give me a first hand report if you are ever in the area.....

PFC does have temp correction (Lamda) BTW.

I'm not sure what you're referring to.

PFC generally uses only the existing sensors. On the SR20 motors there is no measure of air intake temp, therefore the PFC cannot correct for this. I don't think the RB motors have this either.

Lamda refers to the stoichiometric air/fuel ratio of 14.7 and is not directly related to temp correction. The PFC does use the O2 meter for closed loop (cruise) mode.

Sorry gav I meant temp compensation lamda as in this comparison:
