I was looking at APEXi's website today and was reading up on the VAFC II. I know it has a knock program in it but I was wondering what people thought about the VAFC II compared to the original. I'm considering selling my original for a new one.

 

IMO from the cars that Ive dyno-ed it's not as user friendly. It takes a while to get used to. I absolutely love the appearance of the black version 2! I can't wait to get my hands on one for my BB1

 

i just finished the install on my vafc 2. it works a hell of a lot better than the first version. before i had it on a 00 si b16 with all bolt on and supercharge at 9psi and it worked alright but didn't seem as accurate. now i have a ls/v-tec with turbo and it works very good. when i lean it out 20% engine dies even with fuel upgrades. my old vafc wasn't as accurate. plus its good because you can use it on the ivtec engines. and there are more fine tuning points than the old. i do agree that it isn't the easiest to use, but you will get use to it. let me know if there is anything i can help with
