Reon Posted August 20, 2021 Report Share Posted August 20, 2021 I am trying set up an ls2 with the early map sensor, but it only shows 35 kpa, not around a hundred as it’s supposed to ? Any thing I may have missed? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 20, 2021 Report Share Posted August 20, 2021 What voltage is it showing on the relevant AN pin? You can view this on the analog tab of the runtimes screen (R key or F12) Quote Link to comment Share on other sites More sharing options...
Reon Posted August 21, 2021 Author Report Share Posted August 21, 2021 It’s showing.84 volts and 33kpa on the dash Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 21, 2021 Report Share Posted August 21, 2021 That is not the correct voltage for any known GM MAP sensor. So either the pinout is wrong or it is not what you think it is. 0.84V at atmosphere would be a very high pressure sensor something like 5 to 7bar. The common LS1 sensor is about 4.7V at atmosphere, the common LS2 sensor is about 4.0V at atmosphere. Quote Link to comment Share on other sites More sharing options...
