Online Tuning Tools

As many MazdaSpeed enthusiasts are looking to achieve 400whp+, the OEM fuel system becomes inadequate. A solution to this is the additional injector (5th/6th port) system using the R4 controller. Making the OEM ECU and R4 controller play nicely is key and we have developed an in-house calculator to help tune the R4 fuel table. Remember to scale down the MAF table in the OEM controller by the same percentage of fuel added by the R4.
