tach circuit board issues
This post is for information. I have a 1980 and had my tach fail a couple of months ago. I bought a tach circuit board from MidAmerica. I have usually had good luck with them but after installing the board my tach read double the normal RPM. I called them, they sent me another board and a return shipping label for the first one. This one read way low. I returned both and they sent a third. This read high. I tried to adjust the calibration pot but it was very sensitive. I was pleased with their customer service but they had a real quality issue with their boards. I bought one from a guy on Ebay who makes them and supplies them to some of the other Corvette places. It visibly appeared to be a neater board and was accurate right away. The moral is don't assume you need a new tach, even reputable places sometimes have quality problems.
The guy who made my board is John Gardner and he says that Central Corvette and Zip sell his boards.

Very much interested in his address too! My tach is off the wall lately, jumping all over the place. Could you post his address or how to get in touch with him.
Thanks
Dave

a member of this board ACECO ( George ) can
repair your factory board, he did mine over a year ago
and pretty reasonably at that. he also tested it before sending it back so i knew when i installed it back in the car it WAS going to work.

contact info and filter response
Thanks 78IndyPace for giving John's info. For more info, his email is
jtandjudyg@aol.com.
I contacted him through e-bay. He doesn't often sell through there, though. He and I exchanged a couple of notes and I realized that he doesn't just know about his boards but he also knows the short comings of some of the other boards. His price was the same as elsewhere (about $60) but his product works. When I asked about his return policy he even offered to send it to me and trusted me to pay if it worked or send it back. Wow!
Dwncchs, I am still using the original tach filter. It is working fine with the new board.
