What is the fuel press value based off of in megalogviewer, where is this value coming from? Im running MSPNP9093 Original Firmware. I can't do too much internet searching from work because our internet flags any time I type "Megasquirt" to look up manuals it classifies it as ****...which is understandable due to the name

Also having a lot of issues with car trying to die on tip in.

Lastly I had a weird voltage drop in the middle of log, I think basically computer shut off on decel for less than half a sec around 2015s...weird.

The MSPNP does not have an input for fuel pressure, so its value is not valid. It's not used for anything anyway, just like oil pressure or VSS.

Good to know on the Fuel Press thing. No oil pressure is a little weird considering the miata has an actual sending unit; I wonder why that wasnt incorporated in the MSPNP9093. I ninja edited my first post.

Thats because it isnt integrated into the stock ECU. To set that up you'd need to run wiring for it, build the input circuit, perhaps get a new sending unit. I don't know of anyone who has done that.

Don't integrate a functional oil sending unit into the ecu, way to go Mazda.

^Not surprising really. The water temp sender that feeds the gauge doesn't go to the ecu either, there's a separate one for that.

Most cars run several CLT sensors and the Miata has one for the ecu.

Not much an ECU would do with the signal anyway - unless you wanted an engine kill that shuts it down if the oil pressure drops. This isn't a very common feature.
