I finally got mine going ! I used an uncommon wire coming off the coil as a tach. Turns out I had it wired ok to begin with (and help from quynce's post) . I found the problem by comparing my instructions which were for a manual transmission with those for an automatic transmission. Under the training the tach section the two sets of instructions were almost identical except the automatic ended with push the red button. The instructions I was using did not include the red button statement. So after training the tach I pushed the red button. I wasted three days of work over an omission in the instructions.
hmmm i wonder if that my problem too...
brunetmj: what wire exactly did you use? wire #?
quynce: what DEI alarm do you have? i have a viper 790 im trying to get working. it keeps reading "No or Low RPM". am i just not learning the tach correctly. i've tried both the C9 green of f the ecu and the uncommon injector wires too. according to my manual it says to hold the valet button and start the car, when the LED stops flashing and is constant then it is programmed. when i do this the LED seems to stop flashign instantly which does not seem right to me.
