Both are meant to tune your air/fuel ratio, for Unichip, even more. There is always a max that u can squeeze out from your engine using these two tools unless u mod further. Tuning at high rev or WOT without a wide-band O2 sensor will not be accurate as stock O2 sensors works well only at around stoichiometric mixture (14.7:1). Unichip is meant to be tuned to the driver's preference by a good tuner who knows what he is doing; for power or fuel economy, your choice.

A V-AFC2 can only adjust air/fuel ratios and VTEC point. The Unichip can do ignition timing plus all of V-AFC2's functions. Why bother to downgrade?

 

Air/Fuel ratio tuning alone can never produce adequate gains. I would buy the AFC only if I want an expensive looking useless toy in my car.

maybe it depends what baseline we start from lor:- if the owner has already done quite a few other mods but without 'cleaning up' the ecu, he may not be getting optimum performance/fuel economy etc. so if he uses these devices to do some 'cleaning up' he may gain both. After that, power and fuel ecomomy will be less likely to go hand in hand.... smile.gif
