BS2 project - kart tach, speedometer and engine temp

Hello,
I am about to embark on a school project with my 15yo son.
Project will involve using the BS2 with a Seetron BPI 216 lcd display for
creating a racing kart tachometer, speedomter and engine temp.
My first concern is using the BPI display. I bought this years
ago and was wondering if there is adequate support now.· Is this
display the same as what parallax offers in the serial lcd?· Will
programming be the same?
For Tach, we have purchased the Melexis 90217 hall effect from this site
and we have it working on our BOE.· Has anyone used a reflective
tape combined with optical "eye" or does the Hall effect route make sense?
For temp, I have used the LM34/35 sensors before but am also considering the T/C
route.· Any input on whether the LM or T/c would be preferred?· We were planning
on picking up engine temp right on the head, there are concerns about vibrations.
Anyone use any type of IR sensors?
Thanks for any input
Curtis

The BPI display should work fine. I had to problem finding info on the web.
I would stay with the hall sensor.
The normal temperature sensors only go to 300 degrees F, I don't know how hot your engine gets.
If it's hotter than that, you'll probably need to use a thermocouple. If it doesn't get that hot, then I
would recommend using a digital (SPI) temperature sensor.
