6 secs of chirping during startup
During startup, as you insert the key and bring it to the "ON" position, there will be 6 chirps ("ting"), at a rate of 1 per second. By the 2nd chirp, the instrument panel would have been "initialized", and if you listen closely to the rear of the car, the fuel pump too would have been ready.
I make it a rule to crank after the full 6 chirps/seconds is up, and during times when I'm impatient (like 2-3 times a year), I crank after the 2nd second. Am I paranoid? Any technical basis to crank only after the 2nd or 6th second? (In case anyone's looking at me weird, I'm driving a JDM R18, closest equivalent to the EX). |

You're not helping yourself in any way. Once the ECU is active (which is before your starter can turn over your engine) your plugs will fire and your fuel pump starts up. The instrument panel is initialized before your key makes it far enough to activate the starter. Your ECU controls your instrument panel so it's displaying what the ECU tells it to. Your ECU doesn't tell it to update the display everytime it takes a reading from the various systems it monitors. If it did your fuel gague would spike everytime you hit a bump or went up or down a hill because of the pressure and surface level differences. Watch your display closely, all those lights don't turn off at exactly the same time which should tell you that it's not the instrument panel that's initializing, it's the ECU taking the time it needs to accurately read adn average out the information it needs to show you what you want to see on the panel. If it takes 3 seconds for all of the lights to go off and/or stabalize, then it takes your ECU 3 seconds to gather the info it needs and process it for you. It takes a few thousand readings per second and "averages" them to display what it does.
Basically, just get in and start it. You're not helping anything by waiting, but you may be hurting some of your systems. |

Yes, originally I did this - I waited for all the lights to go off/stablize. Off the top of my head, the slowest one is the airbag, at ~ 4-5 seconds. Over time, and esp when I'm not in the driver's seat watching the instruments, I'll just wait for the audio chirps to go off.
