or you could just switch the tach to tap into a fuel injector wire. worked wonders in my experience

does your car have PATS? of so what bypass are you using? if could be the positioning of that. run tachless like stated. and u have to reprogram the brain for the second acc. from sec ignition. you can do it with the valet button or a bitwriter but you will need the new bitwriter chip or bitwriter2 to mess with these new systems

i think we used a K04 bypass and had to use a spare key for my car. yea it's still sporadically shutting down, not sure why. never remember to run shutdown diagnostics after it does it....also this sounds dumb but i'm not sure where/how to tap into the injector for the tach...i don't want and can't go tachless. it didn't stay running and without a bitwriter at my every disposal i can't reset the starter timing. PRIMARY concern is programming the 2nd accessory for the climate control....kinda the whole point of remote starts....i can't follow on how to program it via valet switch. have gone thru the manual over and over and it just keeps sayin how simple it is to do....with a bitwriter....plus like you said it's gotta be bitwriter 2.6 or better to be compatible......any ideas?? thanks a million guys

check your data wire. its probly a dirty signal, at the shop on a few cadillac devilles we had to put a relay on that to clean up the signal. you can take it to a shop and have them write it and diganois it.
