Will the LS tach output run the factory tach and is the LS temp sensor the same resistance as the older chevy to run the temp gauge? Been reading your threads for a couple of years and your creativity has inspired many areas of my 71 lsx build. You the man dude
Thanks, Curt

Yes, they are still available, I will send you a PM with payment details.

As for the tach, they will work with the output from the PCM, but you will need to change the 'tach resolution' in the tune from 6 to 3. LS engines run on a 4 cylinder mode and changing the resolution will double it to an 8 cylinder.

The temp sender has been the topic of MANY threads, but what I usually do if keeping the stock gauge is to use the stock sender that was made for it. This requires drilling and tapping the head to accept the larger sender, but it's not all that hard to do and it's the best way to assure the gauge is going to be accurate.
