Anyone running an electronic fuel pressure sensor with your megasquirt. I'm looking to add on on my 95. What is your setup?

sweet, I actually use the cheap ones from amazon or ebay for most other things but fuel is best to use a good sensor... dont want a fire
I've had 2 of them fail when the engine is up to normal temp for a while. When they cool down, they work again.
Basically, they're good for the first 30 minutes after a cold start.

Is there a benefit to having the oil pressure set up to show in TS? Asking cause i already have a mechanical oil pressure
and water temp gauges installed in the car. Im guessing id have to unhook those gauges in order to get that info into TS?

No benefit. Oil pressure is not an input the fuel injectors can use.

What inputs dose TS use for autotune etc.? Do i need fuel pressure? I just have a gauge on the schrader valve on the
rail.
The same inputs it uses for non-autotune.
Look in TS. Do you see fuel pressure, anywhere?

Variable Inputs
Manifold Air Temp (Air temp sensor)
Engine Coolant Temp (Coolant temp sensor)
Manifold pressure/vacuum (MAP sensor)
Air/Fuel ratio (O2 sensor)

Static Inputs
Engine Displacement
Injector size

Looks like MS3, not MS2. This feature cannot be used on a '95 which has a return type fuel system. Returnless fuel systems have pressure sensors & variable pressure fuel pumps and/or controllable fuel pressure regulators.
