i have my sstock map sensor in my 02 ss, i upgraded to the 3 bar map. now my map sensor reads 105kp all the time and the car wont start. i adjusted it but i dont know know the values in hp tuners. the linear calc., there is a field under engine diagnostic. thats for the help

 

The MAP scaler value is what needs to be changed. I use EFILive, so I don't know if HP Tuners calls it the same thing...

 

thanks man, anyone have that

 

I think to run a 3 bar you need to buy a license thru them to change over to a custom os that will allow you to tune the higher kpa resolutions.

 

thats what i did, i just dont know the figures to calibrate the sensor now

 

When you licence the tune 3 bar it changes the necessary items in the tune, then you are supposed to save and "write entire" back to your car. The map sensor should read in the area of 100-105 kpa with the engine not running, and pull down to smaller numbers with it running.
