Problem with timing on lly

[bronson1376]

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.

[bronson1376]

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

[bronson1376]

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

Tune wasn't locked for me. See the above tables.

[bronson1376]

[comnrailpwr]

Repost the tune it's not there anymore.

Hey guys at work now but I do have a tune that is asking for 20* timing at wot at 3150 rpm and my truck is hitting only 15... It's not a very good tune,( it's from my edge race but still proves the point that the timing is not doing what it should. Ill post the tune later tonight thanks

[bronson1376]

ok here is one tune that it doesn't let the timing advance, and the v3 tune I posted before. Let me know how ya opened the v3 if it works. thanks

Check your hard limiters like posted above. More than likely they are keeping you from hitting what you want.

[bronson1376]

Pm sent

[comnrailpwr]

Try This 15570 pm me for details if it worked. made no modifications to any tables or cells but your timing should hit commanded now.

[bronson1376]

Ok sent ya a PM on this tune
