I have a 2014 Q60 (G37 coupe) that I installed a Fortin EVO-ALL and NIST1 harness into. Using OEM fobs 3x to remote start. Has been installed for over a month. Install went well, but from beginning there was one persistent problem: when remote starting, 25% of time car remote starts right away as expected, 75% of the time seems to be delayed, vehicle lights come on, go off, come back on again and after 15 seconds or so the car would finally start. Seems to be a firmware issue, as others on the help forum have mentioned it is a common issue with no solution.
But, today the car failed to start. 42f/5c temperature outside, running lights and brake lights flashing strangely, did that twice and did NOT start. Car seemed to go dark, so I did 3x lock again and car did start.
Why does the car sometimes not start? I have lots of experience installing remote starters, and this one was the easiest, most well thought out system I have ever installed, there seems to be almost no room for install error with the NIST1 harness, so I can only surmise this is a firmware issue.
Please help solve the persistent starting delays and this new no start condition.
