This sensor's data sheet claims to only read down to 50kPa. I assume that I need to configure the ECU to switch to the estimate table below 50kPa.
Would I purposely reduce the delay time for fault, and then set the low voltage to just over 50kPA so it fails to the estimate table?
or am I totally wrong about this approach?
M150/LS Engine / Turbo if it makes a difference.
edit: seems this is a good reason now to use this sensor. So maybe my question is irrelevant :)
Ordered one of these:

I am having some funny issues after moving to the 4 bar map (From 3) and trying to rule out what is going on.
Hi Jordon,
From testing of those Bosch TMAP sensors, they will read down to 15kPa (around 0.3V) I calibrate them to 25kPa when I build the calibrations (as that is the consistent measurement limit of the calibration tool that I use) and then extrapolate the data from that point. Testing the sensors in engines will have them reading down to 10kPa on overrun.
Thanks. I'll give it a go and report back!
