Hi all, I just got shafted on a tach. It was advertized as a 4 cylinder version, but after I insalled it, and it didn't work, I took it out and looked it over. I saw 6zyl and put it all together. On top of that, according to the archives here..it should work, but just be off 33%, but nothing. I mailed the seller asked if it worked, prior to the sale, he said it came out of his 240. I am not going to bother mailing him or tring to get my money back..who cares I guess. Anyone have a cheap 4zyl tach for sale?...Thanks, Franco79 245dl 218k (no tach) If its too good to be true, it probably is...Buy It Now $7.50.
