Sounds like the same problem I am having with my v3 install, I also know there are a few others with this same problem..
When my motor is fired up first thing in the morning, it will idle quite low and stumble.. sometimes it stalls right out.. holding the gas down to keep up the revs the motor sputters...If I allow the car to sit and idle like this to bring it up to temp, I will eventually start to smoke real rich.. and it won't clear until I drive around for a little while .. However, if I start the car, allow it to idle for a couple minutes, then drive away (keeping rev's down and not boosting), I won't smoke at all.. Idle doesn't stablize until I get to aprox 75-80 degrees C on the wolf temp gauge ... at that point the car will idle great..

Starting the motor while it's still warm also presents the same type of problem.. once the motor fires up, idle will be crappy for the first couple minutes.. then it smooths out... I have played around with the post-start enrichment and it hasn't made things any better..

Have you played with the cold enrichment much?

yup i have.. right now i have cold enrichment set to 15.. any higher then that and the motor will start to lope and idle much too rich. I have a feeling hat I've got to try and get some sort of idle control installed.. I've tried to use the stock BAC to keep idle up, however it didn't work too well (I am not sure that the stock BAC can be used).. Any suggestions as to what to sue for idle control, if anything?

Any insight as to what method of acceleration enrichment would give the best results? I have a full range S5 TPS modified on my S4 Throttlebody to give me full range, however I am currently running accel enrichment using the MAP sensor.. what advantage/disadvanage would there be to use the TPS for accel enrichment?

Thanks
Chris

Thanks to Ron Forman and the guys in Australia I fixed my missing problem, it was the trigger. So i'm back to tuning. Ryan and I are dyno tuning it next Sunday so I'll let you guys know how it went.

My car isn't happy with less than about 43-44 PSI at idle, but that's with 4 1600's.

Why aren't you using the S4 TPS? It's supposed to work with the wolf. I don't think that the full range sensor will work properly.

I was more or less experimenting with the s5 TPS .. I've tried both units using MAP accel enrichment and they never made any diffrence.. just been to lazy to reinstall the s4 TPS .. are you using map or TPS accel enrichment?

On an unrelated topic, I have encountered a potentially fatal (to the motor) quirk with my current setup.. Whenever my electric fan turns on, The initial current draw from the fan will cause me to go lean.. almost like fuel cut the moment it switches on.. it quickly recovers, however I have had this happen when going on boost and have heard a little pinging when this happened.. I am sharing the same 12V line for the fan as the ECU and the Fuel pump (this is the way I set up my relay block for simplicity).. I'm not sure if I give the fan it's own 12V source straight from the battery if this will cure it.. I might just end up reattaching my stock mechanical fan and shroud...

I'm using TPS acceleration enrichment. I was using a S5 narrow range TPS, but since I switched to the FD upper intake and TB I have started using the FD TPS.

You may be able to help that my adjusting the battery voltage compensation, but I would try giving the fan its own wire to the battery. I have been having a similar problem, but it's related to my alternator. Once in a while my voltage will go below 12V, causing my fuel pump to slow down, causing a drop in fuel pressure. It may also be a loose wire. So maybe I'll get off of my lazy butt and check now before I forget.

Hey Chris, you won't really notice a difference with different throttle possition sensors if you don't have it enabled via the dip switches (TPS acceleration erichment). Otherwise it is used for minor stuff like fuel cut on decceleration and idle lock if enabled.

You might want to disable map enrichment and enable TPS. This may also cure some of your cold statup problems as the MAP readings may tend to fluctuate at low RPM.

What does your fuel map look like at 500 and 1000 rpms
at 12-25% load?

I dont know if this helps but if you set your 12 and 25 load points at the same fuel level between 500 and 1000 rpms that should help. Also turn off your all your idle adjustments to start, get it idling correctly then adjust your cold start. Hope some of this helps.

Wayne, did you ever take a look at that map I sent you?

I took some of your advice tonight guys and everything went real well.. thanks a bunch.. I ran a new 12V line for my elec fan straight to the battery and it has seemed to solve my leaning out problem.. in fact my wolf isnow showing more voltage when the fan is on, then before (which had me worried).. It is strange how in the wolf diagrams, it showed a single 12V line which you tap into for the ECU/FP/FAN power lines.. I think the next thing I'm going to do is to run a seperate line for the fuel pump..

I've also switched over to TPS accel enrichment.. I did have to fiddle around with a few settings for the car to run smoothly, however I am getting better throttle response off the line .. switching over also revealed some weak spots in my map which I had and the map sensor was compensateing and covering up..

I'm still trying to work out my closed loop settings as it will work most of the time, but at other times it will automatically shut off on me (the dreaded X symbol).. I've really gotta get myself on a dyno as tuning on the street isn't very easy nor safe..

I also appreciate all the responsesyou guys have been giving in this thread.. getting general advice on wolf related tuning is hard to come by.. there isn't a website set up like the Hitmans, the wolf3d fourms are seldom used and read, and the mailing list seemes to only come in spurts.. I hope we can keep this alive in here guys..

One last thing.. I've got several maps of T2's running larger injectors then my current setup, and I'd like to know if any of you have any maps of setups that aproximate mine (I'd like to do a little comparison with my own maps).. I'm currently running

3mm street ported motor
550 primaries, 720 secondaries
to4 hybrid turbo
Full RB exhaust
aprox 13 psi boost using 12 psi mode on the wolf

Thanks again guys

Did you try looking at the maps that come with the wmc software?
