Clamp MAF Signal – Why do it?
The MoviChip ATF lets you clamp your MAF voltage. You can clamp the maximum voltage and/or clamp the minimum voltage that the car’s ECU will ever see, but why would you clamp the MAF signal?

MAF Tuning with MoviChip ATF
What is MAF tuning? MAF tuning is when you intercept the signal coming from your MAF sensor, alter is by a certain percentage before send the altered signal to your engine’s ECU MAF tuning with the MoviChip ATF – What does it do?

MAF Scaling – What is it? When to do it & how?
MAF scaling is when you adjust the signal from the MAF sensor by a set amount, a scale, and send that adjusted signal to your engine’s ECU For example, you want to reduce the MAF sensor signal by 10%. To do this, you would MAF scale by multiplying the MAF sensor signal by 0.9

Apexi AFC NEO vs MOVICHIP POWER TUNER
The Apexi AFC NEO and the MOVICHIP POWER TUNER both do the same fundamental thing. They adjust the MAF signal to adjust fuelling APEXI AFC NEO vs MOVICHIP POWER TUNER – KEY DIFFERENCES Mapping Points The Apexi AFC NEO uses throttle position and RPM to adjust the MAF signal. The MOVICHIP POWER TUNER uses engine load only Wideband Lambda Sensor The Apexi AFC NEO cannot connect to a wideband lambda sensor signal The MOVICHIP POWER TUNER integrates with a 0-5v wideband lambda signal Tuning Process The Apexi AFC NEO requires…
Read MoreECO TUNING with the MOVICHIP POWER TUNER
The main aim of the MOVICHIP POWER TUNER is too increase engine power but it can also be used to improve fuel economy. HOW? At cruise you can choose to use less fuel than the car manufacturer programmed into your car’s ECU WHY WOULD THE CAR MANUFACTURER NOT DO THIS IF IT SAVES FUEL? Catalytic convertors works the best at a 14:7 air fuel ratio ie this is the air fuel ratio where they make the exhaust gases the most suitable for passing emissions tests. The problem is that the…
