Experiences with Wolf V4

[gun-r32]

A big part of my upgrade is going to be the ecu. Ive currently got a Wolf V4 waiting to go in, but Im hearing so many conflicting things about them, and it's kind of making me think twice about installing it. Bad on cold starts, rough idle, not enough map points etc. Ive mainly been hearing this stuff over here in WA, so Id like to hear of any other experiences with them, particularly on gtr's, and also an opinion on whether to hang onto it or sell it and get a PFC.

Thanks

tried the search button?

its been covered plenty of times in Forced Induction and other sections over the past year or so

yes, have tried the search function. The problem is, that a lot has happened over the past 6-12 months with Wolf, and a lot of the posts in those threads are quite dated. I have, in turn, created this thread, to learn of any recent experiences ppl have had

If you find a good tuner then the Wolf ECU is as good, and in many cases better than other ECU's out there. Just don't skimp on the tuning.

gO A PFC WOLF ARE nothing but trouble!......went down that road and I don't rate them!

Interesting...I've got a wolf V4 pro waiting to go into my car, and im hearing conflicting reports as well..My brother just got it put into his car and he's not rating it, which is making me think about not doing it....Be interested as well to see the responses from ppl

Put one in my car too and dont rate them either. They may have some good functions etc, but thats useless when they dont even work properly.

[gun-r32]

when you "dont work properly" what, specifically, do you mean

when you "dont work properly" what, specifically, do you mean

At idle it was holding the coils on (dwell time) for anywhere between 16 - 18 milli seconds. When the tuner told me other ecus (pfc) would hold them on for 1.6 to 1.8ms. Basically meaning there holding the coils on for 10 times too long and will burn them out very quickly. Also i have splitfires and they said they cant guarantee that they wont burn out either. Basically i paid an extra grand for my car because of the wolf and i can pretty much throw it in the bin.

i guess its all depends on the tuner.. have the V4 on my car and all is sweet.

problems with wolf is that-- very hard to find a good tuner..but once properly tuned.. it's a very good upgrade for a car.

If you were refering to my post that setting is untunable. Meaning you can not change that setting its already programed in by the factory.

Kristov, The dwell time setting on the Wolf is adjustable. Find a competant tuner:D

:bs!: Yeah, find yourself a competent tuner.

Admittedly, takes a while to sort out cold starts. But I've never had a problem with idle stability. And 11 load bands * 250 rpm increments up to 16,000 rpm (both fuel and ignition), with interpolation in between, is not enough map points!??! (that's around 300 points each up to 7000rpm)

All you people with problems should really think about getting it tuned by someone who knows that they're doing.

Matt Spry from PITS, Gold Coast tuned a Wolf3Dv4 in my R33 Gts-t and it runs nothing but perfect. NOTHING but perfect.

I have not a single complaint. Never backfires, never misses a beat. Just over 240rwkw on stock injectors and everything runs smooth.

If anyone is Brisbane ever wants to see a Wolf running in an R33, let me know and I'll show you just how well this thing goes.

[gun-r32]

With the cold start problem, would it be fair to say its a minor thing, that is easily rectified by a good tuner?, or is it an inherent thing with all Wolfs?

Dee 33 - Have you experienced any cold start probs with the 33?

The place i went to is well known tuner in Sydney. One of a few places that do tune them. This is not the first time that this has happened to them when tuning a wolf on a r33 gtst. There was a customer that had that happen to them before. Also i can think of 1 thread where this has happened and cooked splitfire coils. All im saying is be careful cos it can cost you alot for a something you cant use.

If what you are saying is true then i will be mighty pissed off as i bought a pfc because of what the tuner has told me.

[nismo33]

yes.. i agree.. they are adjustable.. took them awhile to properly tune the wolf but its worth it.. had to leave my line overnite so they can have a cold start tune.

wolf runs on Map unlike the PFC.. there's the problem of bad idles and cold start.. but again.. once tuned properly.. they are great.

[Dee 33]

My cold start is great.

I turn the key, it cranks a few times and then jumps up to about 1200rpm for 5 seconds settling back down to idle at 800rpm. I don't have to touch the throttle or anything. I just reach inside the window and turn the key for about 1.5 seconds.

Hey mate!

I've got a wolfv4 with hand controller, and apart from the extra time it takes for the engine to start up i love it!, it does idle quite badly on start up in the cold for a few seconds, but i stress a "FEW" seconds.. then it pops back to normal, i don't use it's build in boost control as i have other means for that, but all in all i'm quite happy, i still need to get it tuned and refined a little bit more to get consumption a bit better, then i'll be completely happy.
