Rep Power: 252

Hey I was wondering what are your opinions on these 2 products. A Friend has 2 of them that he will give me for free. I was just wondering if they are really worth having. I know they need to be dyno tuned but does it make a difference.

Free?
Get it and sell it.
Pretty much useless, You need to get dyno tuned for 2-3hp.
Is it worth it? I don't think so.

its worth it if you have other supporting mods. if you plan on getting a camshaft from crower then yes it'll be worth it. but just that itself is useless.

vafcii and safcii are exactly the same except the vafcii is for vtec cars to change vtec points (which isn't recommended anyway). if its free go for it. you don't have to tune it right away and it does other things like monitor engine functions voltage/throttle/rpm etc

yea i want to get an safcII because gearbox said you can use it to get an accurate monitor reading on your idle speed!

what is the actual purpose of the vafcii and safcii though?

thanks

you can add and subtract fuel at 100rpm increments to get an accurate a/f ratio on the dyno. the vafc also adjusts the vtec engagement. i don't think its worth it just to monitor rpm. if you want something like that, check the apex rev/speed meter.

is your car vtec? if it is then you can only use the vafc2. safc is made for cars that are non-vtec
