Viper remote start?

Anyone here have Viper remote start on their M3? Any problems with it, or does it work like a charm?

Viper Remote Start

Wanted to put one in my e46 SMG but the folks at Directed said it would be pretty difficult, so I gave up. Sure it would be the same for DCT. Might be possible in 6MT. I have them in my other cars and they work flawlessly.

I have 6MT. Really interested in getting the A/C started before I get in the car to cool off those black leather back huggers.

You can do that via iDrive. Set a time and it will start the AC and will run for 30 mins I believe. Just make sure to drive the car for a some time after to recharge the battery.

I don't think it will start the engine to run the aircon, what this actually does is to switch on the ventilation at a prespecified time.

This implies that the aircon is battery run by an electric motor, which isn't the case.

Correct on first point that it only switches on ventilation, not a/c. However, to your second point, using the timer to turn on ventilation will partially drain the battery. It is only suggested to be used if the car will be driven some distance after to restore the battery to full charge.

Edit: Aircon is not battery run, but ventilation via the timer is battery run.

Using the timer, the ventilation runs for 30 mins max which will indeed use battery power but I don't think it will drain it substantially (unless the OEM battery is swaped for a smaller / lighter battery).

Of course if the timer is set / forgoten to run every day and the car is not used afterwards to charge the battery then at some stage it will be drained (although I am sure there must be some protection preventing this from happening i.e. not allowing the ventilation to start below a certain battery power level).

You can't set it to run everyday automatically. You have to reset it (i.e. re-check the check box) every day. Only the time of day setting is retained.

Under climate there is a tab headed 'Independent Mode' if I'm no mistaken.

They hack and cut your ignition wires when they install remote start. I had it in my old Benz and it was awful.

Is the timed ventilation really that useful? Anyone in a hot climate tried it? I suppose I should try it, but I figured if it's 98 outside, I'm not going to gain much, maybe cool the air a bit but the surfaces will probably still be scorching. If not timed right it only takes 3-5 minutes to reach searing air temps again. Whether it's 120 or 105 in my car, I'm still going to have to wait for the A/C to kick in before becoming comfortable.

I use it very frequently. It makes the first few seconds in the car much more pleasant than they'd otherwise be, but it doesn't make a huge dent in the air temp. That's why I'm curious about the remote start.
