Problem with timing on lly

**bronson1376** · July 2nd, 2013

Hey guys, new to efi, but have been working with a tuner and we are having problems with the timing not advancing past 15-16 degrees even tho the tables for the tunes are commanding much higher advance. Has anyone seen this before and is there anything I can do to fix it? My truck is a 2005 duramax thanks

Could be lots of things, post tune file and I'll take a look.

I will post the file I have.... Not sure if the tuning is unlocked to view but ill post it as well as some logs.we can get the same tune on a single tune to advance but not when it is In a dsp5 file for some reason. Yes it is on the right tune while logging just to clarify. Ill post them here soon thanks

Here they are, the try 2 log is with the single tune and the timing advances, the july 11 log is with the same tune only in dsp5 format with other tunes and the timing doesn't advance. thanks

Look at table B0992 (Maximum Timing Map, Pilot Off) and B0993 (Maximum Timing Map, Pilot On).
