I was wondering if anyone has any maps for a TII for the wolf 3d ??? ...or if anyone is familiar with the wolf and can answer some dumb questions ...

Go ahead and post your questions.

I have a MAP for the 3.1, but I'm assumimg you could transfer the data, even if you had to do it manually...

Just let me know...

Evil Aviator

It won't transfer because the 4.x has a slightly different (better) scale for the load bands. I already tried this by spending all night interpolating the points and feeding them into the 4.0 with my friend. You can use the 3.1 map as a reference, but not directly. It isn't a good idea to put someone else's map into your EMS anyway.

Evil Aviator rule of second-hand EMS maps: Look but don't load. ;)

I'm with ya, Evil.

But there are hardly any Wolf maps floating around, period...not even to just look at.

Evil Aviator

You can look at any EMS map. The load bands may be a little different, as well as the timing accuracy, but you can still get the main idea.

If someone will tell me how I will post my map as it is now.... Or at least I will try. ...any comments would be welcome ....Also having trouble with the cold start .....any help there would be greatly appreciated...... I know the car is running rich but I suppose that is safer

It would be tough to interpret the maps from other EMS's to be meaningful in the wolf world... since staging of the secondary injectors are mearly a percentage of the pulsewidth of the primaries, you have to take into account that with wolf maps, you are setting an overall pulsewidth for all injectors at all loads...

This may, or may not help out some of you out there..
The wolf is a great EMS.. however there are some tradeoffs that come along with is... the following is just a bit of ranting and a bit of maybe usefull info I have found during my journey into the world of Wolf tuning (ver 3.1)..

It seems like one of the biggest complaints out there concerning the wolf has been it's inability to control a good cold idle.. unfortunately I under go most of the same cold idle woes as others, but I have managed to improve it quite a bit recently.. I belive there are 2 contributors to the cold start problem.. #1 inability to use the BAC valve with the wolf #2 inability to accurately adjust the cold start enrichment ..
without these 2 key elements, I don't belive there will be any solution to getting a good cold idle.. When the car is fired up in the morning, with coolant temps as low as 5C, the car idles in around the 500rpm 25% load point (I'm using 21 psi mode).. the pulsewidth at this particular load point is much too high to keep a steady idle.. now throw in some cold enrichment into the mix, and you start to realize that the motor is being drowned with fuel while it is cold (I see about 10.5:1 on my wideband).. this results in a very poor idle, along with alot of smoke, if it sits there too long.. I could remove fuel from that load point and get the car idling smoother while cold, however as it warms up, fuel is oging to have to be added back to the load point in order to hold a correct hot idle... A working BAC valve that can introduce a bit of extra air into the equation would help tremendously.. however I have yet to find a single wolf user who has managed to hook up the BAC valve and get it working correctly..

The Wolf is very very sensitive about the ammount of battery voltage it reads... do yourself a favor, while the car is idling, confrim with a multimeter that the voltage displayed my the wolf, is the same voltage at your battery... chances are the wolf is reading much lower than what you are seeing at the battery...Now go over to the relay's that you have installed for the wolf.. check the voltages there.. are they lower than what you are seeing at the battery as well?? ... Unfortunately, if you followed the wolf wiring diagrams to a tee, you would have ran a single 12V line from the battery to provide the 12V for both the ECU and your Fuel pump... unfortunately, in most cases the single 12V line you ran from the battery to the relay's is not enough and you are getting voltage drop by the time it reaches the wolf.. (and your fuel pump) .. I just rane a second 12V line from the battery straight to the relays.. Prior to doing this, I was measuring 14.8V at the battery, while the wolf showed 14.0 (dropping to 13.5 with my headlights on).. this played havoc with the voltage compensation (abnormally richening things) and overall idle quality.. after running the second line, I am now reading 15V's at the wolf, and 14.5 with my headlights on... the wolf is happy, my idle is happy..

I've heard some people complain that their cars would start to smoke and run real rich if it was left to idle for too long... one of the main reasons for this situation, is that people forget about air temp compensation... some people turn them off completely.. as you sit at idle, the stock IC starts to heatsoak, and your air temps start to increase quite abit... (this should't be a big problem for guys with FMIC, however it's till good to have some air temp compensation turned on, since air temps will still start to increase as you sit still) as the air temps increase, you require less fuel to keep the car idling.. if you have air temp compensation too low, or turned off, the wolf will not lean the mixture out and you end up running overly rich and start to spew smoke..

There are a few other things I can ramble on about here.. but this is turning into a novel.. so I'll jsut shut up now.. However If it helps anyone, I have my current wolf ver3.1 map available for download if you want a peek at it..I've been doing quite a bit of tuning with my wideband lately, and so far, this has been my best running map ever

the particular's of my car's settings are:

720cc primaries / 1600cc secondaries
FD fuel pump
malpassi FPR set at 42psi @ idle @ athmosphere (0 vac)
T04b hybrid turbo @ 14.5psi
Stock IC
Wolf 3D running in 21 psi mode
MAP based load sensing, TPS based accell enrichment

Sorry about the length of the post guys.. I tend to babble on and on...

Opps.. almost forgot to provide the link to download the map .... Get it HERE

derb22

Babble as much as you want ...The more information out there the better........What did they change between the version 3 and the version 4.48 ?? anyone know ?

Evil Aviator

Yes, the old 3.x Wolf didn't cold idle well.

This is not so unique to the Wolf. Even when comparing maps of the same EMS you still don't necessarily know the size of the injectors, number of injectors, fuel rail pressure, engine compression, TPS scaling, and many other factors.

I agree with the babbling, lol. The big change is from the 3.x to the 4.x. The 4.0 is a great deal better. I haven't seen the 4.48 yet, but four of the RX-7 owners in my area are upgrading to the 8-channel Plus model. The Wolf web site has a 4.x to 3.x comparison.

Wow, Chris, that was great.
I'm going to check out the voltages and do the added wiring if needed.

I've been pulling my hair out trying to fix that cold idle.

Thanks for the map dL, too!

*Edit*: On a side note, I noticed our ignition maps and parameter settings are very very similar, so I must be doing something right.

I have V4.56 of the Wolf now and it is much improved over V4.4 that I had before. They have added quite a lot of new features, the best of which is 3 screens worth of Min - Max datalogging on the hand controller. It also allows you to adjust the Load Scale and has more modifiers for boost control.

If anyone want a copy of the Manual for V4.48 (I don't have it for V4.56 yet) then let me know an I will email it to you.
