Having a pretty big issue with my recently installed remote start. I had it installed around Christmas time and found that under cold circumstances, I'm talking like under -10 degrees Celsius, the car fails to fire up. The remote starter will crank and crank, try three times, and then fail. OR more recently (in the cold), just crank and give a really bad overgrinding noise that won't stop. BUT, if I go out and manually crank the car myself, absolutely no issues. When it's warm, the car starts fine but I still hear hints of overgrinding. At the moment, we've been tapping into the ignition coil for a signal. I've come to the conclusion it's an improper tach wire and the problem is I'm not sure where you would get or tap into for this. I've been looking all over Acurazine and here's what I've found so far:

One thread tells me that the CMP (Camshaft Position Sensor) should be enough and that it worked for the OP of that thread.

Then I look at this thread that alludes to a Brown/White wire.

Then I find a thread that tells me these are the definitive tach wires.

All in all, I'm not quite sure which one of those wires I should try to help alleviate what's happening in the cold. Maybe one of you have a little more insight? It'd be greatly appreciated, because what's the point of a remote starter if it doesn't start in the cold.

Did your installer do the "tach learn" procedure?

Connecting to the tach wires going into the ECU is easier because you don't have to go through the firewall. You can use any of those 6 wires.

What security interface/ bypass module are you using? The tach signal should be able to be generated by the module via the databus in the car.

lhoo

Here's what I found somewhere else:

brown, red, blue, yellow, black/red, or white/blue at
any fuel injector, black 2 pin plug, pin 2

For my TL, I ended up using a DBALL module.

Sorry for the late reply on this, it hasn't been much of an issue now with the warm weather.

As far as I know, my installer did. If he didn't would the remote start still work?

Either the SL2 or SL3, I remember the installer trying a newer module and then swapping over to an older one since the newer one didn't work.

I read that the signal off some modules aren't good enough sometimes, I'm assuming you found that wasn't the case?

lhoo

My remote start works 100% of the time with the DBALL.

If your problem is temperature dependent, then it could just be a bad connection somewhere.
