[QUOTE="Acoustic, post: 116604, member: 728"] Very very long time ago - I present the possibility of 20v ecu is capable of self compensating with endless possibility. As usual there is a discussion and debate. Today, there are more people agreeing to it. But being a user my self, I also wish piggy bag would work - but I know better - they will not ..... 20v ECU does not take O2 sensor as feedback alone. It also takes water temp, air temp, distributor timing versus engine rpm It also takes guess work like ISC duty cycle for a particular RPM, for a particular TPS, for a particular vehicle speed, and estimates the gear ratio. This is my suspicion... Hi EFN, from Vincent, a E-manage on 20vMAP - was immediately counter attack by 20vMAP ECU. Another 20vMAP with SAFC also- I think 20vMAP more inteligent than 20vAFM My 20vAFM ECU will take 2 weeks to self adjust completely if I do not full throttle everyday. But if I full throttle for 20 minutes, for all gear ratio, various speeds and all. it will self compensate this fast. 20 mins. For all I know I only need to simulate all gears full throttle enough already. [/QUOTE]
