Hello Guys !!!

I need your help please

My friend and I are thinking that I have a problem with my AEM EMS.

Before to send back to AEM for checking and fixing (in case it's corupted)I would like to double check because I'm living in South Pacific

My engine is not starting anymore !!! and this is what we saw quite strange :

With the AEM EMS ecu :
*3bar MAP sensor connected ( http://www.hondata.com/tech3barmap.html )
MAP Computer value : 2.75 volts
Multimeter value : 2.73 volts (using the ground of the battery)

--------

OEM HONDA ecu :
*3bar MAP sensor connected ( http://www.hondata.com/tech3barmap.html )
MAP Computer value : I don't know
Multimeter value : 1.66 volts (using the green/yellow wire as the ground)
Multimeter value : 1.67 volts (using the ground of the battery)

So if you could let me know your value, that will really help me to solve my problem even only on the computer...(AEM program)

Thank you in advance for your help

 

First off, throw that map sensor away and get a good one.. those GM sensors are JUNK. They are slow, they do not have a linear response, and they are JUNK, there is a reason they are $20

 

Thanks for the advice !!!

 

have you tested the aem with the stock map sensor?

 

Yes I also tested with the stock MAP sensor only :

With the AEM EMS ecu :
*OEM MAP sensor only connected

MAP Computer value : 3.24 volts (using the green/yellow wire as the ground)
Multimeter value : 2.35 volts (using the green/yellow wire as the ground)

MAP Computer value : 3.24 volts (using the ground of the battery)
Multimeter value : 3.21 volts (using the ground of the battery)



OEM HONDA ecu :
*OEM MAP sensor only connected

MAP Computer value : I don't know
Multimeter value : 2.96 volts (using the green/yellow wire as the ground)
Multimeter value : 2.97 volts (using the ground of the battery)

 

Update :

I received my new AEM EMS and the voltage is ~1,61....1,62 volts

And my car is starting now.
