26000* spark advance?!?!

[trippyjoey]

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.

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?

I have an ostrich 2.0 with a G1 adapter and the memcal plugged into although it wouldn't be the first time it has come loose
