PSC1-004 Programmable Signal Calibrator AFM to MAF

$ 389.00

Product Description

This product will soon be discontinued.

The PSC1-004 is a laptop programmable calibrator that is specifically designed to implement conversion from an Air Flow Meter (AFM) to a Mass Air Flow (MAF) sensor. Conversion to the MAF sensor removes a major restriction on the engine resulting in higher power and efficiency. The PSC1-004 provides a way to adjust the reading from the new MAF sensor so it matches the reading from the original AFM. It can also be used to optimize the fuel mixture for other engine modifications. It is programmed with the Split Second R4 engine management software.

In addition to the calibration function, the PSC1-004 implements several other critical functions. It performs elevation compensation so the fuel mixture does not go lean at higher elevations. It also filters the signal to match the response time of the original AFM. This assures smoothness along with improved throttle response. The PSC1-004 is included with MAF Kits with a P suffix. This unit can be special ordered with the data acquisition option.

The R4 software included may have issues running on Windows 11. See the tech note “Run the R4 Software on Windows 11” for more information.

Legal only for racing vehicles which may never be used upon a highway.
