computer tachometer display is doubled

I am a newbie with a just installed megajolt lite controller on a Ford 351 cleveland. My computer tachometer display shows double the rpm that the engine is actually running. I believe it is a problem with the controller as my soft rev limiter comes on at about 3600 rpm. Any advice would be appreciated as I'm just learning with this system.

Thanks in advance!

I looked at some old posts and found another that was having the same issues as me. I just did as he did, I hooked up my laptop again and now it works perfectly. Tach is right on and rev limiter doesn't come on early. Now I just need to figure out how to tune it!

Glad you figured it out!
