[QUOTE="actuator_bypass, post: 136897, member: 4976"] I think (My opinion) Chip tuning is more perfect but it can't be tuning at real time like aftermarket ECUs. These is some of the content of the ECU temperature Speed RPM HI/LOW WOT AFR Knock Retard Knock Attack Rate Spark Retard Spark Advandce Volume Effiency Power Enrichment and a good tuner will tune according to some of versus table ie Pressure vs RPM Maximum Spark retard vs RPM Knock retard vs Pressure Accelaration Enrichment vs TPS Power Enrichment Vs Spark Corection Crancking A/F Ratio vs Temperature Air Fuel Ratio vs Temperature Idle RPM vs Temperature There no problem at all after a few homework done.. Cam duration, PnP,oversize valve Stroker Kit, Engine balancing and Lithgening Big Turbo, Extra Injector, Big Injector.. Good tuner will know what to do, which or when some part need some be modify, install i.e stock map sensor can only support less than 2.5 bar fuel pump, fuel regulator and more.. It can be done and it's already been done by some oldtimer.. example like AMS = Anuar MotorSport [/QUOTE]
