Hi James,

Sorry didn't want to Hijack your thread..

I wanted to ask Lee and others... Which other Map Sensors can work instead of HKS one?

Thank you

HKS Maps sensor set up calculations

For HKS type 3 map sensor (the one you mentioned) the parameters shown on Fcon is X=3, Y=4 and Z = -375

The equation used to work out the pressure from the output voltage is

Pressure in mmHg(where 0 is regarded to be vacuum)= X x Voltage in mV / Y + Z

i.e.

Pressure = 3 x voltage / 4 - 375

So if the sensor is outputting 500mV,
P1 = 3 x 500 / 4 - 375 = 0 (mmHg)

If sensor output is 4500mV
P2 = 3 x 4500 / 4 -375 = 3000 (mmHg)
