how come whenever im coasting, like when i let off the gas on the highway or whatever, my timing goes down to 9-10*.... it doesnt necessarily cause any problems, and it goes right back to normal when i come to a stop and it goes into the idle tables i guess, but its just annoying...

 

Post your tune, yo. Could be a few things.

 

Do you use hp tuners?

 

Does it drop in a nice linear fashion? If so it may be DFCO.

 

How do I post a tune??

 

I would say its DFCO but like Smokeshow said, it could be a few things. When replying, click on Go Advanced. There is a place in there where you can attatch files. Post your tune so we can check it out

 

Y'all just wana see what a supertune5000 looks like!!!

I'll post it here soon...

 

 

I like that timing table!!

 

who tuned this? the VE table looks...strange/wrong..the spark table looks ridiculous as well, its a 6.6 right? whats the static compression ratio? boosted im assuming? your Maf disable is at 0hz, and your high rpm disable is at 0 rpm..so i wonder what airflow table ur pcm is using for fueling... and your truck doesnt go into the 'idle' tables, even if it did your idle spark tables are all at 30 something degrees, so you shouldnt see 9-10, fix your burst knock threshold, its all zeroed out "enable delta cyl air", do you have a return fuel setup with a vacuum referenced fpr? if so then you are good if not then scale the fuel injectors..and with injectors that big, you have to scale down all the tables that g/sec or any airflow units in them, why? because youll max out your spark tables, so you have to multiply all the tables by 50 percent and then transfer all the spark rows up depnding on your multiplier, so if you multiply by 50 percent then in the .96 (gcyl) row multiply it by .5, so the .96 row is now .48, so put the values for .96 all the way up in .48 g/cyl..and etc.. but i may be wrong about this tune, thats why your ve tables and spark tables are strange because of the size of the injectors so it could be running perfectly fine, i have just never seen a tune file such as this one


for your timing problem you might want to check this table, engine>fuel cutoff dfco>dfco entry spark.. then click threshold and put the timing values you want at the corresponding rpm.. should be in the early teens in stock form, also check spark advance table a and b and the blenders...take a good look at the blenders...they should help you with your problem
