HPT changed something a little while back. Depending on which version you have doing a regular write can change the background stuff. I just tell people to write entire to make sure it's done...
So tapping the tb got it to idle down??? Just got back from my MRI. Will take a look in a bit. That VE, torque model and everything should have been really close to what you need. Putting the torque...
I've started seeing that message on a few that people are posting on here in the gen V section. Just thought it may have read wrong in regards to theirs.
I do know it's possible to have a corrupt...
It's most likely going to have to be forced since it's been f'd up for so long. Basically going to have to force the throttle to relearn. Also whomever tuned it prior changed some of the idle torque...
Write entire. Do a throttle clean reset. Set the base temp before writing. Then drive and hot idle. Torque model should be closer for you now.
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...
