I have a 93 delsol with b18c1 T3 .48/.60 super 60 turbo intercooled with dsm 450cc and a vafc. I have never set a vafc before and all i can find is settings for d series motors. Can someone help with just some basic settings?

thanks
steve

set your fuel at -36 all the way accross for wide and narrow. once you do that just keep playing with different settings until you notice it feels right. or you can just get a wideband.

stevecivic

is -36 going to make it run really rich?

projekteg

maybe a little, but you would rather be rich than lean, justs set it at that, drive it and feel where you may need to add or take away more fuel, it may even feel fine like that, but i would suggest getting a wideband or taking it to a dyno, c1 isn't a cheap engine to be tuning with the "*** dyno"

stevecivic

how much am i looking to spend on a wideband setup? I have a air/fuel gauge now. thanks
steve

projekteg

air/fuel gauge suck ***, they're not good for ----. i think there is a wideband for sale in classifieds, not sure though, maybe like 100 bucks for a used one, or you can just take it to a dyno

stevecivic

is a wideband just a more acuarate air/fuel gauge? I was told that the widebands cost 400-500 dallars. Just by taking it to the dyno how will i know what is right? Or just when i have the most power.
thanks

Most dyno's have wideband readings.
