Thanks.

One more question
Is there a way to program the oil low pressure alert only when the RPM is above a choosed value?

Now I get low pressure alert every time I'm on idle
I want it to alert only on high rpm

Hi I'm using a g-force sensor with a 0-5v output. -3g = 1v 0g = 2.5v +3g = 4v So I did 2* a -5 to get it to show properly.. I have connected it to adc2 and displayed it as a boost pressure.. I did (x10) put in 20*a - 50 to get a more accurate reading, faking a extra decimal.. But how do I add decima...

if i log 4 sensors, how long can i log until memmory is full, and starts to overrwite?
is it expandable?

i have seen 20min with 10 sensors?

i will log:
RPM
Oil Temp
Oil Pressure
G-force via a 0-5v sensor
