I have installed an Ultra Start 1280-GX11 on a 1999 Stratus.  It does not have the factory alarm or security key.  (Key has a black cover.)  I am very frustrated.  I purchased the alarm off ebay (mistake, I know) and I had everything working just fine.  I am only using the remote start and the remote door locks.  Once I had all working, I needed to unplug it to re-route a wire under the brake pedal.  Now I keep getting a tach lockout condition (7 flashes) that won't clear.  I clear the unit, relearn the tach (get the horn honks and 3 light flashes that indicate the tach was learned), and try the remote and get the seven flashes again.  I called the person I purchased from, and he says to keep unplugging the unit, clearing, relearning....., and eventually it will clear itself out.  I have done this for about 4 hours now and am getting nowhere.  Is he jerking my chain?  Do I have a bad unit?  Is there an easier way to clear this out?  I am using the black/gray tach wire on a 4 cylinder engine.  I have tested and retested my grounds. Any suggestions?

if i ever reset a unit this is how i do it. unplug antenna, cut all power to the unit. using a wire or anything to short the negative and postive terminal. They say that electronics can hold onto a charge so i jus tshort it to get rid of it. my moms car used to have a ultra start. i had the same issue after having the car serviced at the dealer. i couldnt relearn tach and short the unit did the trick. i always do this to reset units so it works for me. try at own risk.

I like tedmond's idea of shorting the unit's positive and ground inputs.....that works for a lot of stuff.

Also, make sure you have it unplugged for more than just a few seconds. Unplug it, go do something else for a few minutes, then come back.

Also, it might be interesting to set the unit for voltage-sensing mode, remote start the car a few times, let it settle down for a few minutes, then go back in and see if you can program it for tach again.

If all else fails, it just might work satisfactorily in voltage sensing mode anyway.

I appreciate the help.  Here is what I have tried:  Switched tach to blue/gray wire at coil pack - No change.  Cut power to the unit, and grounded out any charges it may have held - tried this twice - no change.  Tried setting it to what Chris is referring to voltage-sensing mode - I assume this is what the programming instructions refer to as "tachless".  The instructions say there are two modes,  1 horn honk - tach, 2 horn hoks - tachless,  When I program, I find a third horn honk condition - not sure what that means.  My instructions say that for "tachless" there should be nothing connected to the tach wire.  I have tried all three modes with the tach wire hooked up, and all three modes with the tach wire unhooked, each time clearing out the unit between switches.  I am back to square one.  When I try the "tachless" mode with nothing connected to the tach wire, I always get the 7 flashes condition popping up before I can even start the car for a tach learn.  ie; I cannot get it to function in "tachless" mode.    As far as leaving it unplugged for more than a few seconds, two different evenings last week, I left it unplugged overnight and still got no change.

One more thing I might add.  One of my resources, a CD I purchased from Car Alarm Pros, states that the tach input should vary with the RPM's.  I have yet been able to find a wire that does that.  All the tach wires I have used show an approximately 12 volt output on my multimeter.  I even pulled the plug out of the dash behind the tach and tried those leads.  Unless I had my voltage setting too high for a good read, none of those currents varied with rpm either.  I think I had the correct plug because the tach did not work when I had it unplugged.

To measure tach, set your meter to AC, not DC.

Have you done a system reset through the programming? If you haven't it is key on off on off on and hit program switch on antenna and let go, siren will chirp if you are in program mode. Then hit and hold program switch until siren chirps 3 times. then shut off key, wait 5 sec and start, siren will chirp 2 times if tach learned, 4 times for auto tachless.

**If the vehicle still does not start, check all connections and check for a factory installed

anti-Theft system. If the Anti-Theft prevents the vehicle from starting the remote start will

flash the park lights 7 times. The system does not have to be Tach learned if this

happens, simply start the vehicle with the key and let it run for 5 seconds then turn off.

Do you have the black or grey key?

I have the black key. There is no factory alarm. When I speak of "clearing out the unit", I am referring to the system reset. Each time I do this, I get the chirps and light flashes indicating tach is "learned", but when I try the remote, I get the seven flashes condition again. What puzzles me is that it worked initially with 8 to 10 successful starts from the remote, until I unplugged it to reroute the wires. I have retested all the connections at the plugs to the unit, and all seem to be getting a signal. I spoke with the company I purchased it from again today, and they are going to swap it out with a new unit for me to try. I will post the findings. Thanks for all the help thus far!

I may be misunderstanding what you posted, but once you do the system reset, you have to perform tach learn all over again (start car, led's on antenna stays on, and lights on the car stay on until the unit learns the tach signal).  After do that, you should be able to remote start the car.
