This will include the PNP adapter for your ND1/2 MX5 - If you've boosted your ND with a Supercharger or a Turbocharger you'll need to give your ECU more visibility on actual manifold pressure. Your stock sensor will read somewhere around 3-4psi of boost depending on your current atmospheric pressure. That's not enough for tuning! 

• Direct PNP for the ND1/ND2 
• 3 BAR (29PSI after atmo)
• Genuine BOSCH manufactured
