Can I use an aem 5 bar map sensor on a hondata s300? Or do I have to go with gm 3 bar map sensor because im going over 30lbs of boost thanks.

 

you can use the aem

 

You can use whatever sensor you want, just make sure the ECU knows what size. I, personally, think that the AEM 5 bar is WAY over kill. That will read up to 58psi! Most turbo hondas don't boost that high, and a major downside to using a 5bar is you'd lose resolution of the signal. Because every map sensor is is 5v based, that voltage is scaled a lot differently with a 5bar. Most SEMs can do well with a 5bar because it can read that voltage better, I don't know about hondata though. If you are going to like 32-33 psi, I'd go with the AEM 3.5 bar map (which can read up to 36psi). It all depends on your application though.
