Air flow replaced with MAP sensor

Post by Geoffrey Dick »

Stupid question, is it possible to replace the air-flow meter with a map sensor from a later vit 1.6 engine? will the ECU recognise this change? at the moment do not want to run a new aftermarket ECU if i do not have to. removing airflow meter will help when installing my new sc.

There's no way known you'd just be able to swap a MAP for a MAF sensor, reprogramming would be needed for sure.

SC = supercharger? :?

And you're not planning on having to install an aftermarket ECU even after bolting that on?

no way map uses a 0 - 5 volts signle maf sencer uses ohms signle :x .as for no aftermarket ecu. might get away with only a riseing ratregltor if only running 6psi :lol:
it will go or it will blow

thought that might be the case, will use MAF to start and then convert to MAP (on board megasquirt) if needed

you can run without a maf with a retune but the map is mandatory for smooth running and load changes. mafs are highly restrictive and not at all accurate. i toook the maf off my chev and had it retuned to suit. swapping to other units from different models can be quite successful - chip torque have worked wonders esp with nissans. it is not possible to swap a maf for a map, however you should have a map as well.
