hmmmm....didn't know that i need a aem wideband to install the vafc2. That's good to know. I am pretty sure the setting is pretty much similar to the vafc(first version). Thanks TitusS2k
The reasoning behind buying a wideband is to monitor your AFR's when street tuning to make sure you dont lean out too much and pop your motor. And whats also nice about buying an AEM now is you can intagrate it in with your standalone later if thats what your plans are!

Personally im buying a PLX wideband and fiberglassing it in behind my cupholder, then also flushmounting in my VAFC2.

AEM standalone, now that's sounded good there! i am still waiting to catch a good deal on that ones, but as for right now vafc2 do me just fine until i am going FI.

My mods right now are Rick's header....rs*r exhaust....comptech tp and dual air-ram run straight to the IM from under the car.

Hi, i am just installing the vafc2 along with the frog-harness...plug&play. Anyway, i searched the vafc2 setting and all i could find was the library of the vafc setting and so i go by the vafc(first version) setting. My car started but it won't hold the idle and die off on me. If i hold the gas then it will start right up....but if i let off the gas then it died on me....
And so i unpluged the whole thing and plugged back the stock and the car started up fine. If anyone are using the vafc2 on their S....can you show me your setting....i would appreciate very much....thanks.
Sounds like you didn't do the TPS calibration

From what i have seen VAFC's as low as 85$ where as most SAFC's hold their value on most forums... my .02 cents.
Very good point...used VAFCs are plentyful...not so many SAFCs out there.

Off topic, but where did you get your frog harness from ?
