my friend and I are going tune his 97 Base Prelude 5sp. He has a AEM CAI and DC 4-2-1 headers with a High flow cat and a V-AFC II and just picked up a Wide band Oxygen sensor. I need to be able to tune it with the Apexi unit But I don't know **** about tuning with a/f ratios, etc. . .

I looked around for any info and found very little.
Even some good base info to start with, with those mods.
Can someone learn me a few things or guide my towards the ways.


Turbo coming but may be a little while do to money

 

Does anyone know how to tune with a V-afc and a wideband or does everyone pay someone to dyno tune.
