    Question 26000* spark advance?!?!

    So this morning on my way to work tunerpro was picking up 26000* of spark advance for a few seconds while driving. Anyone know what could be causing this error?

    I get the same thing sometimes. It's not always timing for me, sometimes the BLM has a blip as well.

Dart 165cc Iron Eagle S/S heads - 72cc chambers - 1.94 / 1.50 valves. Isky roller cam - 204/209 dur @ .050 - .480/.496 lift with Comp Magnum 1.6 rockers, Edelbrock 3704 intake - Bored to 52mm - 454 throttle body, Delco EP381 fuel pump @ 18 psi running through 80# 454 injectors. Hedman Headers into 3" Dynomax exhaust.

    Okay, but should I be worried cause I'm also suffering from low and varying oil pressure under load( 40psi when it used to run ~70psi) and light misfire at idle and it all started after this.

    I ran into some WEIRD timing issues just like that when I converted my '77 Cherokee to TBI and it was the chip not being 100% set in correctly. Is your chip removable?
