two different map readings same car
two different map readings same car is there a different sensor for the pid map and the sens map it seems that i might have a two bar map as it reads 50 kpa at with engine off from the sens but with the pid map (not custom) it will read atmospheric >98 wtf??

In HPTuners the 2-bar (and higher) OSes add a PID for the MAP.
The OE / stock one is a dumb voltage translation with the stock
scale factor. If you read 50kPa KOEO then you have a 2-bar MAP
sensor installed and are looking at the wrong PID.

thanks, still a little confused. i bought the car with it installed i have the stock 2000 os i guess i will try a wot run and see what it logs. How does hpt derive the PID table map reading?
