97 astro, remote start

I can't upload entire manual file size is too large

what about tapping into 1 of the sensors with 5 volt signals

Have you tried leaving the tach wire unhooked? The unit might be able to sense a voltage change through the main power wires.C Renner's Auto Electronix

Have not tried that yet, will give it a shot

I still will have to go back to my earlier post about the programming options being listed in the manual. I know I'm kind of kicking this horse to death, but I've done several brands of remote start and all of them, sometimes very deep in the poorly written/translated owner's manual, had some sort of instructions to change settings on the remote start that maybe look something like this: Run time - 10 or 20 min. Sensing mode - Tach, voltage, oil pressure Unlock pulse - single, double Etc., etc., etc. The method of programming varies between brands...usually it's a combination of pushing the brake pedal, switching the ignition, pushing the valet switch, and pushing buttons on the remote. I think it's unconscionable that they would not have anything at all about how to program written in the owner's manual; however I couldn't find this manual on the net anywhere - if you have a link post it and I'll take a look. As far as your starter kill idea, it's good in theory; however most remote starts that I've done will shut off the ignition after a few seconds or so if they don't think the car's running(which all indications are is your problem).

bear with me, I will scan the programming page for you to see, I cannot see anything that would have to do with programing tach signal
