i have a quick question

does the GM 3 bar map sensor need to be calibrated into the AEM EMS??

my car ran perfectly with the stock map sensor, but as soon as i installed the 3 bar it wont even run. It starts fine but stalls after a second or two.
i disconected the vaccume line from the 3 bar map and it runs fine at idle... any ideas?

yes you need to change the map sensor voltage settings on the EMS.

 

phew.. ok thanx... i goto the dyno tomorrow morning and i thought i just made a big problem by installing the 3 bar!! thanx

 

Why do they even make you go through all the hassle? Why can't they be like other ecu's and be able to choose;
1 Bar
2 Bar
3 Bar
???????????????

 

They do have that. You do however have to re-scale the maps to run your desired boost levels.
