525 Mercury Racing 5 Beeps Alarm
Hello All,
Wanted to see if anyone could help me with this issue.... I have a 525 Mercury Racing EFI which has been recently serviced but now has 5 beeps every 55 seconds. My mechanic scanned and this is what came back:
He said that the first item "IDLE MAP STR" is what is causing it and the others are just showing up because those sensors are not hooked up. He noted that it would be the IAC so i replaced with a brand new one. However it came back (alarm). Also I notice the idling is low and a little shaky so it has to all be related. Any one help point me in the right direction? It would be greatly appreciated.
Thank you!!!

Found in a 2013 thread that its being caused by the MAP. Not saying this is it but check the volts output of the MAP
