Tuning Guide: MAP Sensors
It is possible to use different MAP sensors other than Apexi (or Toyota) with the PowerFC.Issues you will come across and will need to address are:
1) connector suitable for MAP sensor is required.
2) connector suitable to connect to PowerFC is required, if utilising boost controller port.
3) pressure equation parameters.
Here is a table of MAP sensors, determined through specification or reverse engineering:
