I'll def work on lowering the idle, just had it up to ensure I can start/drive her.

Thanks for the suggestions.
I pulled 50% out of Cracker under 2800rpm, that helped the cruise but didn?t solve it. My AFR leaned out a bit when I did this as well.
Since that worked I zeroed...
I?ve been screwed by invalid injector data in the past so it actually looks like I may have learned my lesson.
I probably would have been happier if you were right and the fix was that easy.
Hey Sirius,
I get why you think that and I checked this a bunch already, they are the right values just off by a little.
Looks like they get changed to the next valid value when you enter the...
Went for a 15min drive, Tune and Log included. I touched up the VE based on the log but haven't changed anything else.
It still stumbles/surges when the throttle transitions from idle, once I'm...
BK, yeah, thats basically where I'm at, I just over utilized my cut&paste skills a smidge. She starts and idles like a boss now, it's when I pull it into gear when the sadness begins ;-) but yeah no...
Okay, I hate to leave a thread hanging so I thought I'd update...
I believe one of my problems starts with coping a tune... Sure it's a good thing to start with a known good tune thats close to...
Got a little surging going on in gear at light throttle and I'm thinking my spark tables need a little help.
My question is should I line up my IDLE spark (PN/Gear) with my base spark (hi/lo)...
Thanks again all..
I do have some good news.
For starters, I pulled 10% of the VE across the board based on observed AFR on my gauge BECAUSE I have been struggling to input the info from my...
Okay....
Validated wiring AGAIN, it's correct
Bought a different 232/usb cable, drivers are up to date and still no makin it happen...
Went in and grabbed my older IBM ThinkPad and it...
Deleted the files in Vehicles.
Repolled (after the automatic repoll)
No Dice.
Device manager see's both the scanner and the afr cables, all looks normal, and it picks them up dynamically when...
Thanks for the responses, yeah it?s really rich, this was the first real drive.
I?ll find/pull the idle adders throw a few tranny channels in the scanner and post up a new log. I?ll check the base...
I really don't want to agree with you... but it does feel that way for sure.
And while I'm not the best tuner the Throttle Cracker values in the tune are from a stock '04 LM4 which I know isn't...
Alright, just took this one.
I noticed it will settle in around 1500-1600 RPM in gear foot off brake. Check out around the 9 min 10 sec mark, foots off the gas for 30 sec I used the brake to slow...
misery loves company....
My little addition is:
I get my channels to stay and log AFR on RARE occations.. not sure what sequence(s) in my Channel Dance is working for me but I'll start going...
Also I do have a log but pretty sure the channel list isn't right, I can take a new one and include the right channels... just need to know what folks might want to see.
Yeah... sorry about that thought I included it last night, I think I got it attached right now.
Got a 6.0 with a 4l80e and using a P59/DBW setup.
The tune came from a similar build except it was a DBC.
I just got this put together and just started setting up to tune her.
It idles fine...
The Holley wasn?t bad for drivability but it?s not the OEM in terms of addressing just about any condition.
What brought me back was:
Durability and Warranty, If the Holley PCM goes your out...
Thanks BS, that helps validate whats going on.
I tried Holley and decided to use OEM/HPT for this build. I'm looking forward to using OEM/HPT again and not afraid of digging into some tuning....
So I have a tune from a cammed 6.0, building a replica combo ( accept I "need" to use a LS1 style FAST 92mm intake vs a truck intake, yes I know but wanted to hear about fuel first) and I'm planning...
Guess I'm being stubborn and stupid at the same time.
After a few runs I didn't get too far with eliminating the lean spike on PE/BE transition. I'm pretty sure that condition was not present...
Certainly not a MAF expert but I'm gonna run a MAF. This is a daily driver and I'm shooting for the whole experience. I get there are tons of guys running SD out there and super happy with it but I...
Thanks for the PE tuning tips. I just added them and will check it out tomorrow and see if it helped the transition lag in PE/BE.
I went with conservative timing and will get after that in a bit,...
Working thru tuning my Gen 3 turbo 2 bar build.
Failed the MAF and setup OL
Tuned the VE tables to a reasonable point up thru ~10psi (street tuning)
Flipped the MAF back into play and left it in...
