I should also mention not to be surprised if torque and timing are all different again. You can touch up torque at a hot idle in park with the ac and heat off after a drive if you need to. If the...

Yes you are correct. If it's ONLY open loop fueling "on startup" having the problem, then only open loop should be addressed, BUT odds are, it's all of the fueling as a whole or at least that's what...
Yes and open loop fueling for the whole temp range. However, this doesn't mean that it may not need to be 0ed out. I actually just checked the last stage 3 and 1 gpi cams both that I did I had found...
Might want to log trim errors against tip temp and dial in tip temp table too.
As best I've concluded, which can be 100% incorrect, tip temp especially on the newer ones seems to be characterized for a running engine and is why you can take the same injector and have completely...
Tip temp should be dialed in. I dial them in on all of them I do. Airflow changes through the motor changes the fuels effects, thus changing the tip temp characterization. I've not had a hot start...
You'll need to load this one then dial in your VE and MAF tables.
Engine temp wasn't hot enough to know 100%, but you're anywhere from 10 to 20% off in places right now just with that quick log. I still have to correct your tb.
You do have a 6.2 intake and tb? Give me a couple... I'm almost certain I have those defined for yours.
MAF g/s airflow and VE g/s airflow. People don't know this and I had to find out the VERY hard way, but base temp needs to be set to ambient temp anytime you flash the ecm. They just take for granted...
Well again, this corresponds to how much difference having one thing right can make with everything else. Now your engine knows it doesn't have those and it's completely changed the fueling and...
Compression will still check good with a stretched valve. Been down that road. You have to pull the covers and take the rockers loose to measure valve tip height. I'm not sure why I had thought it...
Best to check on the dyno. Make sure to use a load bearing dyno with simulated road profiles if at all possible.
Im willing to try it as long as it doesn't cause other fueling issues with alternator voltage drop or heavy electrical loads
Wouldn't it be better to dial in the tip temp table? That's how I normally fix this remote tuning them. You're essentially doing the same thing, but with crnaking and initial start fuel before the...
These LT4's are pretty resilient. I've seen them have more bottom end bearing issues than anything to do with a piston since they do have forged pistons, BUT if it's been that hot they are notorious...
I guess this wouldn't be a common problem since it's been run like it has, but that is indeed a bank 2 circuit code. However if it sees a lot of knock such as having an engine problem or something...
Your tune file ;) I was going to check and see if I had the definition to just make the change quickly for you in regards to the etc max and effective area tables.
If you can't change that background table set, you might want to put that etc max setting back to stock. I've seen in rare instances where having the 2 so different would actually cause some idle...
It can be. It's called throttle mode or something like that. I would dump quite a hefty dose of marvel in it if correcting the injector data and reworking your VE and MAF tables don't solve it. Might...
Well, I mean if it didn't do it before and nothing was changed with the build, then it would have to be a mechanical associated item. I guess it could be idling at a different airflow requirement now...
Are you sure the injectors and rails are clean? Not to mention the lines to them? This could simply be a supply issue, but usually you see that with rpms on top of off idle. You could even have...
So are we to understand that nothing on the engine has recently been changed and this issue just started out of the blue?
Well, I said that and then found out Will has shut things down for a few months until he can get caught up with several other things. I think he even took down the site to be able to do so. I know...
This is a channel config you can use since it's boosted. If you need to add anything, you can.
To load - download - right click - show in folder - copy - open scanner - open recent channel config...
