I've had good success tuning our LS engines but completely new to the diesel world. I've been reading the small list of tuning help here in the diesel section but I'm still a little fuzzy.

I live...

I use Hptuner to tweak on our LS engines. I'm looking to buy a 99 Suburban with the vortec 454.

Can I tune this vehicle with my HPtuner? Would I need to update or download anything or is it...

Okay gotcha ;) Confusing at first, thanks for baring with me.

If it's here, a search isn't turning it up.

Surely someone here has messed with this enough to provide the ins and outs, tips and tricks?

Simple questions aren't getting anywhere here. If...

Did I stump you guys? :D

MMGT1, if you are talking about the rpm enable table, then I'm not understanding that table correctly.

If I raised the entry and exit rpm (which I believe you to mean the enable/disable) then I...

Hmm, are you talking about a fuel table or the rpm enable table??

Ghost, I went in and lowered the rpm enable on both cars. I didn't mess with disable as it was low already and didn't know how far I should go with that,,,for example...

My 2000 SS camaro had...

Went through stickies in different sections, VCM Suite General, VCM Suite getting started, V8 Engine Tuning Gen 3, GM V8 Miscellaneous Tuning,,,,I can't find a sticky with a DFCO heading.
Search...

Wonder why the sticky guide never popped up with a search?? I can't find any stickies on it at all....

Guess it would help to tell what I'm working with. it's a 2004 6.0 vortec (LQ4) that I...

I'm sure this has been covered, but can't seem to find any info on it searching around.

I'd just like some guidance or ideas on what everyone does to make the DFCO more effective, or how to go...

Is there an instructional video in the help section that specifically targets setting up an MAF histogram to work on conjunction with my wideband to show AFR % error?

I've been beating myself...

Ah okay gotcha. Thanks Google.

That's not a working link you posted. What are you telling me? Is that an email address?

I didn't see any links on the main page for sales that jumped out at me,,,so I just asked through the contact button along with my information. Hope that's okay.

I'd like to upgrade my older version of HPtuner to a Pro version so I can log with my wideband.

Is this possible? Thanks, Larry.

I completely removed mine. I just accept the fact that someday it will fail and It'll give me an excuse to build the trans better.

Well I've been waiting for over a year now and about...

Sounds like something I would like to tinker with.

How does it work exactly???? Does it affect another table as far as another math equation??? Up or down does what exactly???

I...

Sorry,,,,I meant zero the "throttle follower airflow vs TPS" table.
Go to: Engine-idle-idle airflow-,,,,,then under throttle follower section there is a tab that simply says "airflow" ...

Hmmm,,,well should I just zero out the IAC airflow table then????
Since these decay numbers do nothing but subtract from that table,,,,,why not just zero the IAC airflow table and do away with...

Well here's what I see in my tune (02 camaro) Some of what you are saying wouldn't seem to work and actually appears to be the opposite of what the description bar says for these tables.

...

Not to butt in but thats something that has always bothered me on the LS1,,,,,rpms never come down quickly,,,,and I never could get a clear explaination as to how to adjust.

You mention getting...

Thanks for that last bit of information. I wasn't aware of that. Can't wait to try this out.

Sounds good. So with the filters setup properly I don't have to worry about hitting PE while driving around? That would make hitting some other cells much easier that I normally can't get to...

Okay that makes sense to me,,,,,thanks.
