2017 5.7 Hemi Tune assistance Cam, lifters, Injectors

[Robinsonsauto]

Here is my most recent log. idle trims close.hpl

[Robinsonsauto]

test drive 1.hpl Sorry for the delay. finally got her out for the first test drive. please see attached, I included exhaust cam center pos. 125 deg

[Robinsonsauto]

wanted to add a couple note.
1. initial cold start up high idle isn't bad, but as it steps down she feels a little unhappy.
2. idle is pretty aggressive as well would like to mild a little if possible.
3. Transition from drive to park almost stalled once

try 1st smoothed attempt VE speed density 2017 Dodge 5.7 truck norris startup v2.hpt

here is a file that should help soften the idle, and also raised it alittle to see if that helps with stumbling. also it would help if you logged a few more pids. trans gear. afr(if you have a wideband). throttle voltage. and knock retard for now

[Robinsonsauto]

current idle trims better after pull ve2 matched b1.hpt current tune.hpl Sorry I'm Just now seeing this. i have since made some more slight VE Table tweaks. will I be ok using these current VE tables with the changes you made? if so i will load this in and add the pids and share a new Log

[Robinsonsauto]

Just got done loading and test driving, runs well it seems the the hard surge coming to a stop at times is a little better. idle is averaging around 800 feels a little to high in drive, like I'm holding it back, little high in park and natural as well.

this has the stock o2 sensors. im struggle to get the Ve table much better than what you see it at now. here is the recent changes

You have the stock unmodified tune file for this vehicle?

Second question is, what name brand injectors or what did they come out of? You have data for them?

[Robinsonsauto]

Yes, here is the stock file. I'm using the stock injectors currently... stock compare.hpt

aside from the high idle on my last run she ran like a champ. I would like to get the VE Tables for b1 b2 closer to zero as well

2. VVT limiter -4cam
3. hellcat Non MDS lifters
4. long tube headers

See if this helps at all with the high idle and possible surging at stops. I just made a few adjustments using James's tune with some of the VE changes already made. I made a couple more Ve changes but as you said, there is still a bit of work left to do with the VE tables. I made some adjustments in your exhaust side VVT tables under the Variable Camshaft heading, and I also added a little spark in your Part Throttle table just in the .85-1.00 P Ratio area as well. The tune you have here from James is pretty solid. For the most part, you just have the always tedious work left in getting your VE Tables complete. So, if you don't see any improvement with idle or stop surging, you can just take what you like from any of the few changes and scrap any changes that aren't helpful.

Thanks Man, loaded and logged the timing seems much better I can actually read the timing advanced pid now where as before it would bounce all over. she runs like a champ, but doesn't want to start without giving gas if I let it sit for a bit. I haven't felt the surge return v2 spray-cam.hpl

[james1595]

How long of a bit is it? Is the car still warm? May need to adjust your startup fuel and/or airflow table. Try adding to one and see if it helps, if it doesnt try the other. Id start at adding 10% more of either first.

[Robinsonsauto]

first few starts when cold didn't catch, when warm its hit and miss. 80% of the time she catches, but the other wouldn't without giving a little gas.. Prior would go up to around 1100 rpm for a couple seconds then idle down. this will one will reach maybe 950 then idle down to around 800. feels stable once running

[Robinsonsauto]

Update. after letting sit overnight. it started up great high idle time seemed spot on. so the hard start extended crank time is more after warmed up

[Robinsonsauto]

one thing I did that seems to help a little was reverting the throttle body Model (Airflow) down to the first startup range. (this was an edit I changed prior to the last timing updates while playing) I had added 10%. now that I took some away by reverting back. she kicks off almost every time but barely. if i try starting back to back she wont catch on the second attempt. without slight help from the throttle. here is the current file, that's the only change so far. I tried adding 10% to start up airflow but that didn't seem to help Current back off 10% Throttle body model arflow V2 Spray Cam Adjust 1.hpt

[edcmat-l1]

I know you have someone else helping you out so I don't want to step on toes, but if your start is better when you crack the throttle, you need either less cranking fuel or more cranking/startup air. So try reducing the cranking fuel or adding to the startup airflow, or a little of both.

[Spray-Cam Hell-Ram]

What edcmat-l1 said ^^^^ a lil of both was my pick of the 3, though his first suggestion would have likely been sufficient as well.

[Robinsonsauto]

Thank you guys! she's pretty solid, I really appreciate everyone helping and sharing their knowledge, I find myself studying and reviewing each change building my knowledge, with hopes I wont be as much of a Receiver over time.
here is a decent pull using the most current tune. would you feel comfortable running this tune for a bit? just had a loss in the the Family. its about a 12hr drive? And most likely about a week with limited time.
Hard pull with 2nd V2 Tune.hpl

now that she is so smooth, can we make the idle lope more aggressive? would this be done in the minimum spark base?
