You can source a differnt 'Engine on' wire that will actually turn off when the motor is running on the turbo timer. The problem I see with this is the shock sensor might get triggered while the motor is off or while it shuts down.... I'll post up details. It shouldn't be too hard to do, especially with separate components, but I'm not that familiar with circuit board components, so I'd rather wait for my friend to help me out...
Yep to all of what you said. You need to have an 'Engine ON' signal that goes off when the turbo timer is on but the key is off. I did this by having a relay between the 'ON' wire and the alarm. The relay is controlled by the 'key IN' signal. This way the alarm sees the car on only when 'Key is IN' AND 'Engine ON'.
Now, depending on your alarm, the shock sensor can go off or emit the warning sound while the engine is ON. I, on the other hadn, didn't need to adjust the sensor or anything it just doesn't "hear" the engine. But it warns if I leave my stereo too high.
On other issue I had was the alarm current sensing. When the car turned off the alarm sensed a change in current and went off. There are some alarms where you can change this sensing to start wither 30 secs or 3 min after the car goes off. This is used mostly on cars with electric fans. Anyway, I haven't seen any of those alarms recently and mine didn't have it, so I just turned off the option.
The link I gave above goes into more detail.
