My viper alarm disarms the car after the timer shuts off. How could i keep the car armed while the timer is on and then shuts off? Is auto-arm my only option?

 

That's what the race shops say.

Turbo Timers are a pain in the rear. The only way I know of is to wait in or out of the car or have the alarm set to auto arm in 30 or 60 seconds with the turbo time just under that.

The owners manual says to let the engine idle after "long" or "hard" driving. So if you played Speed Racer or had a long freeway drive, let the turbos cool off.

SO basically you can't do donuts, drive like top gun, shoot in to the garage doing 80 and shut down.

If you putt from the offramp home, the turbo's are cooling down.

 

Viper alarms can be armed while the ignition is on, so I don't know why it would be disarming after the turbo timer.

If you have your turbo timer activate a relay and have that relay activate the ignition you should be able to shunt the ignition input from the alarm while the turbo timer is on.

But it sounds like there is some other issue, or I don't understand exactly your description of what is the problem.
