Hi, I'm new in the forum, Dear, have a big doubt about the map sensor, why do some admissions bring it and others don't? And those that do not have it in the admission, where is it positioned?

 

Hello and welcome to the forums. To answer your question, different markets have different requirements. The reason they don't install them in markets they don't have to is simply to save money.

 

The car is legitimate Japanese, how strange that they do not include it in their market. and thank you very much for answering, I thought it was something positive or negative in the driving, I see that it is something that they wanted to schedule more than anything, but if so, does the flowmeter do the rest of the work?

 

Yes as far as I know, for this generation of evo, the load calculations are Mass Airflow sensor based and do not factor in manifold pressure. The MAP exists for other purposes such as smog and maybe SAS in the markets that had that option.

 

The MAP exists for EGR in the USDM. So the computer knows when it can open the egr valve (when there is no boost). JDM cars had SAS and no MAP sensor, so I dont think the MAP sensor was used for SAS.
