So, if your tach is set for 4 cylinder mode, leave the setting at 6.
as for tach wiring, try this to clean up the signal. I had to add this to my 2003 PCM to make my autometer tach work.  |
Hmmmm,
I thought the resister was only needed if the tach didn't work at all. The tach works, just seems to a grand or two too high or maybe double what the engine is actually turning. Are you thinking cleaning up the signal is going to make the tach read correctly or just stop the needle from wobbling?
by the way, your site [lt1swap.com] was very instramental in getting my car wired and running.....THANKS.
