Anyone ever actually dynoed and found out what the ideal percent of injection before TDC is in an LBZ? I can't seem to find much for information on it. This will be my hot/race tune so I'm trying to...

Anyone ever actually dynoed and found out what the ideal percent of injection before TDC is in an LBZ? I can't seem to find much for information on it. This will be my hot/race tune so I'm trying to...
So in my bigger tune I'm having a de-fueling issue on the big end in 5th gear. I'm just trying to eliminate this as a possibility. I'll just go into the scan tool and see what it thinks I'm actually...
Well I agree unless it's actually limiting how much it will let it make right???
Ok. So is the torque value roughly what it should be making at the wheels? Should I bump it up closer to 1000 to avoid defueling at lets say under 15.6?
First off this is my tuning cal for my 06 LBZ. So I understand that our maximum torque vs. rpm tables are kind of like our rev limiter, and I have it set to 1400 up to 3400 rpm where I ration it off...
Ok I'm following you. Give me an example of an irrational value that you set a whole map to. Also, I set the parameters in the egr to 300.1 degrees coolant temp for turn on and shut off, not sure if...
What would you suggest for someone without a blocker plate? Other than just leaving the egr on?
I was originally asking about the OS swap because I had a truck come in that must've had a dsp2 tune in from the previous owner, therefore I had an X in engine operation when trying to pull the...
Sorry I forgot to post back on here. I get what you're saying, set it the maps to stock and then systematically delete cells until I found my problem. I ended up throwing an egr plate in and solving...
Ok, I was just wondering. I was having some wierd de-fueling issues with some OS's, but not others. Feels almost like the truck is loping but I'm constant on the throttle, almost always around 50mph....
So If I'm looking at the same year LBZ, they've got to be pretty similar right? I'm guessing these differences are adjustable with EFI?
Appreciate it!
If I'd want to set a 3400 rpm rev limiter on a duramax DSP5 tune, how would I do this? Or can I even do this?
Let's say I've got 2 2006 LBZ's with different stock OS calibrations. If I've already got tunes made up for the others OS, does it do any harm to do a full flash onto the other trucks ecm? I would of...
Had this problem on a couple of trucks now including my own. My truck is a 2006 LBZ Duramax, intake, exhaust, lift pump, built trans, etc... Anyways, occasionally when cruising and getting into the...
Yeah I've been doing a bunch of reading on it. So If I want to make my second position my tow tune, and I load my stock cal, do the comparison, find out which tables I need to modify but then realize...
So basically what you're saying is that you don't have as much control over the other tunes because of less tables? If I have a normal single script can I put that into the other slots? How do I go...
I'm very new to efi live and am trying to get it all set up before tuning the truck. I've read the tutorial on the LBZ dsp upgrade which helps but I'm still a little confused. I've read that when...
Today I purchased all of the stuff I need to start tuning duramax's. I've got the flashscan, the v8 and v7.5 software, and have updated the flashscan. I've also got a bunch of engine and transmission...
