just got a sct tsx tuner and now i need to monitor the fuel pressure. does anyone know if there is a way to do it with that or do i need a seperate gauge. if so what and where is the best place to get one.

 

You'll need a seperate sensor to support that. The SCT gets it's information from the PCM, which has no clue what the fuel pressure is; there is no sensor on the engine to support that.

 

i figured that just need to find outwhat i need to do it through the sct

 

I'm not sure you can add a sensor to the PCM/OBD port like that. If you can, I'd love to hear about it. Though I've got the parts to put an Isspro on the A-pillar, so I'm planning to go that route anyway.

 

well the tsx has 3 expansion ports built into it. its just figuring out how to do it

 

If it has expansion ports for external probes and it has the firmware to support the reading of fuel pressure, then it should just be getting the right probe and tapping it into the regulator(in my case) or you could probably do it right at the pump as well.
