Suggest stripping out the conversions so you are looking directly at raw voltage data and see if it makes sense.

99% of pressure sensors will read the full voltage scale at the full pressure range and are linear.

TPS: If your car has a three wire TPS, then yes. Just tap into the signal voltage and feed it directly into a free analog in on the DL1. I did a basic calibration with some data at no throttle and at full throttle. Most cars have a linear response on the sensor, so all you need is the low and the hi...

Those typically use resistance based sensors. The simple answer is no, you can't. The complicated answer is you will need separate sensors and a read through the knowledge base. It can be done, but it's simpler to procure more RT sensors.

Are you using a null cable or not?

Gingerman! Too bad it's snowing out now. ~30 minutes from me.

DL1 Mk1, 2 or 3?

The Dash2 has a trip odometer that is re-settable.

I do not own a Dash3, but you can assign "Distance" to a variable. I do not know if that can be reset to zero.

You do not have a purpose built rally TSD computer?

Not sure of the exact logic in the Mk3, but it is an OR statement inside an IF statement. If I where doing this in excel: IF(OR(left lock, right lock),Light turns on) Left Lock = carspeed/wheelspeed>0.05 (or something, need to experiment) IF(statement, true statement consequence, false statement con...

Start isolating variables. Send one stream of data at a time to one device and see what happens.

I send the RPM to both the DL1 and the Dash2. Just a simple Y wire. Works fine.

Don't aftermarket ECUs output injector duty cycle?

I've often wondered if two fuel flow sensors could accurately measure fuel consumption as described above, but wondered about pressure. Do the sensors compensate for pressure? Do they need to? How about recording injector pulse width and applying an equation instead? Do you have an ECU, and can you...

Unless your fuel system dead heads on the injector rail, you won't be able to measure actual consumption.

Most folks use a tank level sensor to measure fule level directly.

Final drive is the diff ratio. Normally around 1:3x to 1:4x-ish. Put the 3x or 4x number in that box. You need to have wheel speed fed from a hall effect sensor (or converted from a VSS sensor) into Conn-1, pin #8. The rolling circumference of the wheel needs to be entered and the RPM needs to read ...

You have speed and rpm set up as well? You need wheel speed, not gps (IIRC).

Both read properly on the dash?

Pretty sure you need to flash the Dash2's firmware for newer Analysis software to work... (IIRC.)

I've been using the R-T stuff for about 5 years or something and the newer stuff is definitely faster/better/easier to use.
