Considering replacing Dash2/Solo2 with an AIM MXP in SRA

@argonaut, does the MXS wash out in direct sunlight?

No, not to the extent that I have any trouble reading it.

My SRA has an Oil Pressure sensor that the Dash2 accesses via the ECU. When you ran the cabling to the rear of the car, did you use the center channel below the floor that runs from just blow the fuse box to just before the fuel cell? That's where the Dash2 cables to the ECU (and I think the brake light cable) run. Where did you mount the Oil Temp sensor? Looks like I can get Oil P, RPM, Water T, TPS from the ECU via OBDII. I like the idea of having the fans activated by more realistic inputs (Oil and Water T), but I think I'll leave that for a future project. This one is big enough for me!

So I think at this point, I need to run a new OBDII cable from the dash to the ECU and an Oil T sensor cable from somewhere to the dash. I'm figuring out how to install brake pressure sensors for front/rear, and finally the steering sensor. Peter pointed out there's some non-trivial (to me) calibration to be done on that one in order for it to be useful.

The oil pressure sensor is right next to the oil filter. I did not use the wire from the Dash2 loom. Rather I ran a new wire thru the rear firewall via a small hole I drilled behind the passenger seat. The Oil Temp sensor is mounted at the outlet (top) of the oil cooler - so its measuring the temp of the oil after going thru the cooler. This was the location Peter told me to use. I don't think you will get Oil P from ECU, you are going to need to run your own wire from the sensor to the dash. Yes you will get Water temp, RPM and TPS from the ECU (but the TPS...not sure about its accuracy or if I just need to do some configuration - my data never shows 100% throttle, it shows about 75% max).
