[QUOTE="ALBundy, post: 52905, member: 15"] If you buy the portable programmer, then the UNichip can also be program as per when you like it. RM 599 I think! Nowadays, dun need to carry lap top...a good PDA will do it! As for piggyback ECU, what it does is altering the values/signals from the DME to a different value. Things that will be altered are the AFM mapping and ignition timing as well. But but...for cars with O2 sensor, the effect will take place after 3000 rpm, that is when the O2 sensor readings is "ignored" by the DME. IMO, this MAF conversion is a great MOD for cars with air flow meter which is restrictive and problematic! :rolleyes: :) [/QUOTE]
