Conventional Tach on LS2

[Billett]

Called the shop and they told me they can't change it in the tune. I've heard from others that you can, specifically for EFI live, but I have no personal experience. Called automated and they told me that about once a day they get a call from someone who tried the pull up. Circuit with a 680ohm resistor and that it is just too little resistance. They suggested a 10k or 5k ohm resistor instead. They said 1/2 watt, but I have a 1/4 in my hand so I'll try that first and let you guys know whether it works. Going to email the lt1tech site as well so they can let everyone know that 680 ohm may not work for everyone.
