My Megajolt Jr has stopped sending spark advance.. my timing light shows only 10deg.. and its fixed.. my downloaded program map shows cells with 20+deg and it stays at 10deg.. The vacuum port (MAP sensor) is correct and it shows on the MJ jr's gauge and its variable with motor rpm.. My PIP & SAW connections are correct too.. BUT I STILL HAVE NO ADVANCE..
And on another note: When bench testing with my 9v batt, I would get " timeout cylinder count" and I cant do anything,,, the port is connected..but when I plug it into my EDIS on the running vehicle it logs in fine with no errors reported at the bottom of the window..
BUT I STILL HAVE NO ADVANCE.

Re: NO SPARK ADVANCE
Sounds like it could be a hardware error. If you haven't emailed us already, email sales@autosportlabs.com
