Timing not matching table. Please look at my tune and log.

[A62WAGON]

I need some help please. I've been working on my tune, its a 2 bar SD, plan on running 14 lbs of boost on my 5.3L. The problem I'm having is my timing table is not matching the log and I can't figure out what is adding timing?

Any help would be greatly appreciated.

Thanks!

There are several spark adder tables that are in play.
You didn't mention where you are not seeing the expected timing, but you can add all of these pids into your table display and see if one is adding or subtracting timing.

Hope this helps

Thanks, I will give that a try.

Running about 8 PSI of boost now and when it starts to build boost thats when the timing does not match.

I will try logging all of the timing parameters and hopefully find the culprit.

Thanks Again!

Now I see it. You are expecting 10 and it's delivering 15.5 degrees.
What about that flex fuel table?
Is there a flex fuel sensor present?
Maybe 0 that table?

[A62WAGON]

No i dont have a flex fuel sensor. I'll zero that and log all timing parameters. Hopefully try it tomorrow after work. I'll let you know if that fixes it. Thanks for the help.

[A62WAGON]

Attached is a new log of all the timing parameters added that I could find. Am I missing any? Timing still does not match. And I don't see anything adding timing

I cant find the flex fuel table you mentioned.

Zeroed out some of the DFCO tables even though I thought I have it disabled.

Thanks for the help, will try again now that I zeroed out DFCO's

Here, under Spark/Misc

DCFO wouldn't affect spark as far as I know

[A62WAGON]

That's odd, I don't show that table.
But its working now. I zeroed out the DFCO table and that took care of it. Don't know why but I'm happy it did.
Thanks for all the help! Really appreciate your time.

[RonSSnova]

Sure. It helps me learn!
Ok, so there is a DCFO timing table?

I have the latest version of HPT updated mine a couple of weeks ago.

Under FUEL>CUTOFF,DFCO
then tables: DFCO ENTRY SPARK , DFCO ACTIVE SPARK

I zeroed them both. Not sure why that worked, I thought I had it disabled? But now my command was matching log and I felt safer adding a little more timing.

OK I haven't updated my software for awhile. I think I'm 2.24.77......maybe
