unlock pulse duration

Hi, Was look at CM7200 brain with weblink. There is an option menu for unlock pulse duration setting starting from 0.8 seconds which is default. Just curious. Does this pulse duration matter? What is typical setting for reliable remote door unlock/lock operation? Anyone knows?

0.8 works perfectly fine for all cars. For those that use 2 pulsse to unlock (not to confuse with double pulse unlock) First lock unlocks the driver door, second pulse does passenger doors (toyota and lexus) 0.4s is better.Ted

My default is 0.4, works better on Euros.

Hi, Is there a way to change the duration manually? Selection is only 0.125, 0.8 sec. and so on going up larger number. Shop programmed this way, first button push driver's door unlocks, second push unlocks all remaining doors. I observe when unlocking, parking light blinks 3 times, long-short-long(like Morse code K, dah-di-dah) and I am pretty sure they relocks if I don't open door soon enough. When I unlock and walk towards car I can hear click and door is locked back? Can this happen? Lock button gives only one blink and works fine.

You need to go back to the shop, get them to redo the settings.

Depending on the vehicle, the reason you get 3 blinks is pretty simple. The compustar sends 2, the bypass convenience is most likely sending oem unlock codes. The reason it re locks could be based on the cars settings. Ex. You csn program the compustar to relock/arm after 5 minutes if no doors are opened, however the cars settings might say after 30s relock. Since it was installed by a shop have them take a look and address your concerns.Ted

Hi, Again you're right on that. I tried to change the setting from 30 sec. to 5 min. using remote fob. Followed procedure correctly twice but it does not change. In option 1-10. Tried with 2 way and 1 way remote. Do I have to reset current setting and select new setting? Wish I had OP500 unit. Does OP500 works either antenna connector?(4 pin vs. 6 pin) I am so much curious of all this, LOL! Good for old fart's mental health. Thank you all, always.

no need to reset. just make sure once you navigate to the menu setting, wait for it to respond back 10 times (flashes) then make your changes, cycle the ignition on then off.Ted

Hi, That was exactly what I did. F+trunk for 3 sec. > light flash, another F+trunk for 3 sec. > light flash. This will put it to Option 1. Then key button 10 times after 1 light flash response each time. Then 10 light flash response confirming I am at option feature 1-10. The I tap key button, 4 light flash to confirm. This what I did. Ah!, forgot to cycle ign. on and off. Will try one more time tomorrow and will report back. Thank you.

Hi, I spent some time hooking up laptop to brain after disconnecting car battery and took a look at the option 1-10(relock if door not open) setting and it was option IV which is 5 min. Found option programming with remote works fine. Just regardless any setting it does not have any effect whether it is set to default(off), 30 sec., 60 sec., or 5 mins. Always door relocks after ~30 seconds. I even reflashed brain, V.3.03 and blade V1.4. Looks like some thing is over riding option 1-10 settings. I am stumped. Vehicle is 2008 Acura MDX. I emailed to Compustr tech support for any idea.
