Chips available for Boost/Tach Module!

[GNVenom]

Just got these parts in, available now. It's a pair of calibration IC's for the boost/tach module for our GN's and Ttypes, the two custom chips on the PC board in the module. If your tach or boost bar-graph is out of whack (most of them are by now) you NEED this! Look at:
http://www.casperselectronics.com/ and do a search on the 2nd. page search box for 103070. This is the part number of the IC pair. To understand what the IC's do, look at:

You can open the installation page if you have Adobe Acrobat Reader. The IC's are in stock and I have limited quantities. These IC's are specifically made for the GN analog dash and it's a common failure item. The module itself is no longer available and once these chips are out, that's the end.

They are available as a pair, one 8 pin DIP IC and one 18 pin DIP IC. The pair are both on the A/D controller board within the module. Smaller IC controls the tach, larger controls the boost.

Just to clarify any questions, the chips need to be soldered into the PC board, they don't plug in. There are two different chips; an 8 pin and an 18 pin chip. You need to be able to de-solder the old chips to place the new ones in.
Hope this explains it.

The chips are actually precision calibration resistor networks, not LED driver IC's. The LED chips (five of them) are on the other two boards. There are also a few other chips on the three boards, but the main problems with calibration lie within these two ICs. If there are segments that are dead or blank, it's usually a problem with the LED driver chips, not the segments themselves.
Hope this answers your questions.
