S2000 Fuel Pressure in Kpro

I noticed that fuel pressure isn't showing up in Kpro on my AP1. Is this just a feature lost forever with the PRB conversion over to the S2k or is it something that can be wired up? Maybe aftermarket sender? I don't know if one comes stock with the S2000.

How are you / were you reading the fuel pressure?

Maybe I should restate my question because I'm a little confused. What's the "PTANK" value? Fuel pressure in the tank or somewhere else? I'm guessing this doesn't have anything to do with fuel pressure at the rail like I'd hoped but even then, the value stays nill for me.

ptank is the fuel tank pressure and does not give a numeric value, it is either on or off. This is for emissions only.

to get actual fuel pressure, you need to tap into some where (like the fuel rail) and use a 0-5v sending unit. I would imagine you can run it back to the ECU and datalog it through an extra input.

This is what Ive used in the past

Ah. I assume its what tells the ECU if the gas cap is open. Thanks!
