Guest Venture-Z Posted November 26, 2003 Share Posted November 26, 2003 I just installed the crane cams MSD system on my 280, car runs great but my tach is jumping around. If I rev it past 2k it straightens out, but anything less and it's all over the place. I'm running the 280ZX dist and ignition modual, and stock tach. Anyone else had this problem? I already did a search, but didn't come up with anything. Quote Link to comment Share on other sites More sharing options...
EvilRufusKay Posted November 26, 2003 Share Posted November 26, 2003 If you use a MSD you may need a Tach Adapter.

Guest miloz31 Posted November 28, 2003 Share Posted November 28, 2003 I just finished installing a MSD 6AL on my Z31 Turbo. The only time the rpm needle jumps around is at high rpms(5000rpms). Its time for a tach adapter. Quote Link to comment Share on other sites More sharing options...
