So I'm FINALLY getting my FD together, it's been sitting for 2-3 years along with all the parts I need for the build. In my parts pile is a brand new Wolf 3D V4 plug-and-play for the fd. I'm wondering if an upgrade to the V500 would be worthwhile. Here are the details of the car:

GT35R ball bearing turbo
Xcessive LIM
KG parts fuel system
... and I want to keep working A/C with a good idle

The new V4 software looks nice, if nothing else I'll get that. But what features of the V500 would be nice to have with my application? It'll be driven on the street and for track days. Power goal would be in the 430-450hp range at probably 16psi max. I don't plan on using anything like meth injection or an IC spray, so the application is pretty simple really. Only catch might be getting AC working with a good idle, but I've seen that done just fine with a V4.

So those that know the differences, educate me please

 

you can get the wolf software right from thier site, so why dont you DL both versions and check for yourself.

Im not a certified expert, but I dont think the V500 will benefit you enough to change it out. I went from a V3-V500 so it was leaps and bounds different for me.

The key to the idle and AC issue is to keep your idle air motor hooked up and working, the wolf also has ac request signal as well so make sure you hook that up also
