Weird $OD Spark Advanced FIXED, sorta

[skandolis]

i had a simalar issue recently, ended up being the new balancer had the timing mark in the wrong spot due to a timing cover change. new balancer was at 12:00 old one was over on the side like an old school timing tab... i was starting out with seriously negative timing instead of 0 degrees......

Thanks for the post. I didn't even think about the harmonic balancer timing indicator could be inaccurate. If, or when the truck is available to me again, I will put a degree wheel on the harmonic balancer and verify TDC.

My guess is there's a spark bias scaler set at 0 instead of 20

That's an interesting thought. I tested with a stock Memcal. I even downloaded the same BCC from this site, found Zero differences.

sometimes i have to put a,b and so on in the file i started with my files get corrupted some times for no reason?

Can you add a link to the files or add the xdf adx and the stock bin here that you are using

I used my Ostrich 2.0 to verify buffer with chip to confirm the Memcal file vs. the file I downloaded from gearhead-efi.

Your guys xdfs are weird I wondered why the factory cal only had 15 degrees at 100kpa its setup to minus the bias off the main spark tables for some silly reason edited xdf and pow real spark figures 28 degrees up top at full throttle lol.have you ever confirmed actual advance matches commanded advance before this issue
