Re: ls1 swap which speedo / tachometer ??
ACII, if you want to use the pcm signal post your question to "critter". That's his avatar name, he's terry from lone star dyno. I changed from a 5,000 rpm tach to an 8,000 tach when i did a ls1 nova gauge cluster mod and the 5,000 rpm tach was spastic when i put in the ls. Terry was great to work with and his attention to detail is right on the money. The stock pcm tach signal can be scaled up to a higher voltage level if i remember correctly, but get with terry.
