Running MS 1 v2.2 with the 11c1 code.
Recently my 4 bar map sensor was having issues, it worked fine but all of a sudden the load % was about 20 below the map sensor kpa. These values have always been pretty close at atmospheric pressure. So thinking my map sensor was bad I put in the stock 2.5bar sensor and the map was reading 99kpa and load was 100%. Everything looking normal now I ran this setup for a few months till I needed to upgrade the sensor again. Bought a new 3 bar sensor and put it in. Same issue as before now. map is reading 99kpa and load is reading 81%.
The map sensor works fine so is this normal? I shouldn't have to rescale all of my maps from just changing the map sensor.
EDIT: Yes I changed the sensor to 300kps in megatune and the configure mode.

Yea I opened up TS and load still shows 81% but the map sensor is now showing 86kpa. This stuff really makes no sense. I have used MS for prob ably 3 years now and still havent learned everything.
Guess Im just going to try and rescale my maps and then tune it from there. Im wanting to take it past 22psi.

thanks man, Ill have to do some more trouble shooting to try and track it down. Ended up finding a blown turbo gasket so that takes priority to the MS issue. I just put the 2.5bar map back in it so I wouldn't have to change the maps.

The only time Ive had an issue with it saying anything other than 98-100 when not running is when the sensor wasnt calibrated right. I have the 3 bar sensor and it was calibrated for 2.5, making my gauge read like 85% or so.
