I'm getting ready to dyno my car this wensday (3 days from now), and I have gone over the wolf software quite extensivley, but one thing that has yet to make sense is how you tune for specific manifold pressures let's say 15psi.

On the fuel map it shows the tps 0-107 and then the rpms. Well my question to you is, Where does the manifold pressure come into effect?? If I wanted to tune to 9psi for daily driving and 15psi for racing, how can this be done on the same map?

I think I am missing something, or just need something explained to me.

Also why is the fuel map tuneable from 0-15.99?? Does that stand for something.

Thanks for any help you can provide.

 

k after some more research I'm starting to think that the 0-107 figure is the manifold pressure, but it's by percentage??? Percentage of what? the maximum pressure that the internal sensor can handle??

I'm thinking now that the tps is mainly for the transient enrichment/enleanment, overrun cutoff and other things.

the percentage load thing is confusing.

 

Hmmm...

I don't have any experience with the V4 Software, but on my V3 it is different.

You have your %Load on the vertical axis, and your RPM on your horizontal axis. (Maybe your need to reconfigure the software to use MAP and not TPS to display load).

What boost level your percentages result in, depends on how your Wolf is configured. My v3 has 2 configurations, 12 psi mode, and 21 psi mode.

%Load is manifold pressure . In 21 psi configuration 100% is 21 Psi. 87% is 16.8 psi, 75% is 12.6 psi, and so on. In 12 psi mode, 100% is 12 psi, 87% is 9psi, and so on.

That is how you tune for different boost levels on the same map.

The 0-15.99 value sounds like your GLOBAL FUEL SCALE. That is your maximum injector duty in mS. On my Wolf V3, the higher your global fuel, the harder it is to fine tune the values, so you want that to be as low as possible. (Mine is 8.06 for example.)

 

ok after talking to chris from checkpoint motorsports (the man) again

107 load is a generic value, it is actually a percentage

you adjust 0-100% (on the interal map sensor 100% is set to 20psi, but you can actualy creep to 107% (23.5psi))

you can actually set the generic 100% to any pressure you want like 15psi (if that will be your maximum tuning boost) and that will give you a little more tunability in the "in-between" ranges.

like on an n/a you would set the internal map to "0 psi" and you would have maximum tunability for a car that won't ever creat boost .

You can actually set your load to use the tps or map, I believe that the map would be more accurate due to the fact that I'm running two different boost settings.

I'm really starting to get proficent with this system after all this research so if anyone has any questions I'd be happy to pass on the knowledge.

 

Yes, its a little daunting at first, but once you get to know it, it makes haltech seem overly complicated. Of course, im biased since i work with chris often. Ever wonder whos car was the first to learn on

Good luck with your setup, Chris should set you right. The 107% thing is a "just in case" feature. I agree with you in using "map" feature instead of tps, its a better way. I use the tps just for throttle position, fuel enrichement/enleanment etc.....not for mapping my car.

I cant wait for the new dyno, finally things will be easier to tune (in house) rather than going down the street to another dyno!

 

AWESOME! It's cool seeing all the networking in the rx community. I've consulted chris many times and every time he's been extremly friendly and patient.

I'm even running the vw ignitor that he recommended and it's working like a charm.

after some tinkering on the dyno the system seems to control the injectors very accuratley because even the smallest adjustments make a difference in the a/f ratio in real time.

I'm very excited about this ecu, and I've recommended it to a bunch of people so far.



fatty: what do you think a good ratio is for air temp compensation. Assuming that the temp you tuned at is set to zero??

I'm trying to get a ballpark figure so I can set it Immediatly after tuning. I've heard to many stories of people blowing their cars on cold mornings, ect.

 

Hmm, i believe that i set my air temp compensation at the "theoretical value" that wolf says in their manual, but ill have to double check that.

I have my engine temp compensation (enriches the motor when its a cold morning) at 25 or 30%. The wolf tapers it back until you hit 75 degrees C and then its turned off automatically.

Ive never heard of someone blowing their motor with that setting wrong, but then again i dont boost my car until its WARMED UP and thus this feature would not longer be functioning anyways.

Do you have a wideband? YOU NEED ONE if you dont. I have the newest techedge wideband, but im kinda wishing i got the Innovate Motorsports one (although im not totally sure yet). Why do i like the innovate one? Because they have a datalogging program for your values so its MUCH easier to troubleshoot map points on your Wolf. Either way, you NEED A WIDEBAND!
