I got a used AEM EMS that came with IAT sensor & the 5bar MAP sensor. I was wondering if there will be any drawbacks to me using the 5bar MAP sensor or should I sell it & get a 3.5bar sensor? I will likely never see more than 30PSI with my car so I know I don't need a 5bar sensor, but is it as acurate as the 3.5bar sensor at lower levels? I'm still getting all the items I need for my new setup & just want make sure I do this right the first time. Thanks for any help or suggestions you can provide.

 

There isn't any drawbacks (i.e. issues) to using a 5 bar MAP sensor, and you shouldn't waste time selling it and money buying a 3 bar. Since you have a 5 bar, keep it and know that if you ever decide to up the boost you won't have any concerns from a MAP sensor perspective.

 

Cool. I just wanted to make sure I wasn't going to run into a issue at low boost levels. One less thing to wory about.

 

Nope...you are good to go. Enjoy your new setup!

 

Thanks, but it will be a little while till I'm ready to install it & get tuned.

 

I'll trade you my 3 bar for your 5 bar if it makes you feel better I'm going to be running 40psi + soon.

 

Makes no diffrence to me, so if you want it I'll swap you.
