How to Increase Crank Time on Viper Start?

Ok over a year ago I had an installer put in a remote start module on my old Viper alarm system.  The viper alarm system was installed back in 1993.  It is a two button (I believe I asked the installer if it was a 3-channel, where you hold down buttons I and II to transmit channel III and he said no- it is only 2) non rolling colde system (if you open the remote, you can see that the code is programmed by breaking wire jumpers).  I know this is not really important but I guess it might help an expert out there to identify the particular alarm system model I have.

Anyway he put in a module which I believe was made by Viper to work with this system.  When I hold down button II for a few seconds the remote starter activates.

Last winter I noticed that in very cold weather, the remote starter would crank for a second or two and then stop, and the car had not yet turned over, so it was not running.  It does this three times and gives up.

This only happens in very cold weather (approximately below 25 degrees F)

FYI the car is a 92 Honda accord 4door automatic with fuel injection.

The installer charged me $70 to 'resolder all the wires' (*) and it didn't work.  However he said (1) the module was under warntee and the problem was covered even if it took a while to show itself and (2) he believed he could increase the crank time.

(*) Yes, I know how bogus this sounds. I assume he did do some trouble shooting. The original Viper alarm was not installed by him so I am assuming that's why he charged me the labor.

So my question is- does anyone here know how to increase the crank time on the Viper remote start module??

There is a slight chance I have the box that the remote start module came in, which might have the model number on it (I dont think he gave me the instructions).  Also I have the original remotes, so maybe at least the model of the alarm part can be determined?

The directed.com website is running very slowly right now so I am not finding any useful info there.

Thanks to anyone who can help out!!

i'm not sure if it depends on the model of remote start you have, but for starters, you CAN increase the crank time. Search DEI's website for remote start manuals and the programming codes of most of their remote starts and confirm that they are all the same.....or close at least. Then follow the programming sequence which will require you to enter programming mode by pushing the valet button. www.directed.com 

goodluck.

hi if it doesn't crank long enough you can try reving the car up to about 1200 rpm then program the tach signal. if the starter module has a door on it open it up and you'll see 4 switches one will say tach. start vehicle rev to about 1200 flip switch after tach learned flip switch off and shut car off and retest . if no switches then find programming switch and start car rev to 1200 and press and hold button for 2 seconds .  I msy be wrong on the sequence for the first method its been a while.

Ok I have three remote starters so I hope I found the right box.  It turns out to be a Valet 551T.  I found the install manual on the directed website. (Have any of you guys gone to that site recently?  It is REALLY SLOW!)  Apparently I have to locate the module so I can see the red LED.  I thought I would have to add a special programming switch but it looks like the same button that was installed for valet mode is the 'program switch'.  According to the install manual's wiring diagram on page 32 of:

http://www.directed.com/guides/manuals/ig/valet/N551T.pdf

I have to check for a Violet/White wire to see if I have tach sensing.  If it's not connected I'd assume I have voltage sensing.  Page 28 has instructions on Shutdown Diagnostics (my installer was insisting that I keep leaving the car overnight until he could repicate the problem- I assume this is the procedure he was going to go through).  I may wait until the next really cold day to run the diagnostics before I go blindly increase crank time... so far this year it's been good though.

Then tach learning is on page 23, and page 26 has the features programming info which includes crank time setting for voltage sensing setups.

For voltage sensing; I dont understand why there is a crank time.  The manual says the remote starter brain will look for the voltage rise that indicates the car started.  So why have different crank times? Just crank for 5 seconds until the voltage comes up and be done with it?

For tach sensing, what exactly are you programming the brain to recognize? The RPMs that the engine will idle at?  The bran cant control throttle so I dont understand that.
