Piggybacks should be able to do some or all of the followings:

 

1. control a/f ratio

2. change ignition timing

3. remove speed cut

4. change vtec x-over point

 

As far as ES5 is concerned, i understand that most, if not all, piggybacks cannot do point 2 and 4. This is after going around many workshops, eg ST Powered, Autotronics, Garage R, etc., and talking to the mechanics there. If what all of them says holds true, then there is no point in getting e-manage, 0bit, unichip, VAFC, etc. Just get a simple a/f computer and tune ur a/f ratio can leow. No need to waste so much money.

Actually I seen e doings of VAFC2 on my friends Honda Stream. Actually it can do pt 1 & 4. Speed cut you need Apexi RSM which he installed as well. I don't think there's a option to change ignition timing on Honda....I believe its the option for VVti

 

You could actually tune the a/f ratio to suit your driving habits. My friend actually changed his vtec x-over to 4000rpm from 5800. He has been playing ard with the a/f to find the optium. He's also using the vaccum read out on the Vafc2 to determine if its time to clean his air filter.
