The VE tables in this revision I posted are not going to be dialed in specifically for your 2015 but should give you a descent base to work from so you can continue to improve your VE tables over time as you learn how to tune your VE tables. Whatever you were doing to tune your VE tables in your posted tune file, wipe that entirely from your memory. Either you have been wildly misinformed on this topic or you just haven't spent enough time researching specifically how to tune your VE tables using data from your drive logs. I see in your first post where you mention being "very new" to tuning so I have to assume that you probably haven't researched this topic thoroughly enough. But I also know that you are likely feeling overwhelmed with all these different tables and the Hemi tuning platform in general. And you wanna try and learn/understand how to make these changes yourself, but you also don't want it to take forever just to be able to drive your newly cammed 2015, and is why I hooked you up with these VE tables. Now you can get me back by going through this forum and searching "VE tuning using LTFT and STFT", and read through enough posts/threads on here until you feel comfortable enough to where you can make adjustments to the improve on the VE tables from the tune revision that I have given you. And within the next couple of weeks, work to improve your VE tables using whst you have learned and post you updated tune file with updated VE tables right here on this thread so that we can see how you're doing with tuning the VE tables. If you can get this part of your tune learned and nailed down, you should have no problem learning most of the other areas of the tune as well.

spray can revise idle log 1.hpl here is the idle run with that tune, ik my oil pressaure sensor is bad but that cant be whats makeing it want to die it sounds like, def a better chop than before my idle was set too 800.

If anyone can explain knock to me and when i should be shitting my pants, I also cant find any threads on ve tuning and explaining what adjustments I should make according to the information I've obviously have it wrong thru YouTube videos. any links would be appreciated!!

pump gas is garbage these days

consistently exceeding 2v is dangerous for a cast oem hemi piston

not great on the bearings either but all it takes to break a oem piston or crack a skirt is one good ping

this is why ethanol is 100x better for us than pump gas is

not to mention ethanol is 30% oxygenated : )

[jrod2smooth]

In one of those drive logs i went into full throttle and stpped around 120mph it showed 1.2v max is that something i should be worried about

[jrod2smooth]

Here are 2 logs I took if anyone can let me know what tables i need to adjust to get my fuel trims dialed in im very lost on it, ive adjusted my ve tables a couple of times but im not seeing any result to it when i do. my rpm hangs and my throttle response is extremely delayed coming off a stop sign and only till about 1200 rpm is shoots from 800 to 1200 ish and the pedal isnt even pressed hard its really weird. if you have read any of the other post you know im still learning and my time frame to get this ready to daily is getting shorter any pointers besides what gas im using would be appreciated walmart log 5.hplaz log 4 3%.hpljnn.hpl

Not sure what your intention was with this post. In no way does it contribute to this thread, but Ill go ahead and respond, if for nothing else, in hopes of avoiding any future redundant questions and/or posts. That being said, the reasons why you "do not understand" are a combination of, either not reading through each of the posts in this thread thoroughly enough or not absorbing all of the information from the posts that you are reading, and then also, not being privy to the private message conversation between the OP and myself prior to me posting the 2nd revision. If you read the post the OP posted right before my post with revision 1, you'll see that he was specifically asking about getting his VE tables sorted due to erratic fuel trims and is dealing with throttle hang, so in Revision 1, my focus was on his VE tables/Fueling, and adjustments for throttle hang. After I posted revision 1 with these initial changes, the OP pm'ed me asking for my assistance because he was unsure about what exactly to adjust and really needed his car up and running to get to work and offered compensation for my help. So in revision 2, this is when I really went through the entire tune in more detail, hence the larger number of changes with Revision 2. And I'm hoping the reason he hasn't posted on here in 4 days, since I posted Revision 2, is because his car has become drivable again. And considering the fact that you and I chat outside of the forum on a somewhat regular basis and knowing that Ive been writing tunes regularly and for nearly 100 of our forum members here to date makes it even harder to understand why you would post this instead of just messaging me personally and asking this question outside the forum. But in any event, hopefully now you are able to understand why one may change so many settings in a revision 2.

motor job with tbwitten tune.hpl5.7 chopcabra cam current tbwrittien.hpt here are the most recent log and tune, car just got a new motor but same cam setup nothing changed. Temps out are like 5 degrees im not sure if that affects the tune but neither one of sprays tunes are working any body have any suggestions. Or if you noticed something off thank you!!

[LilSick]

its hella fat

the controller is maxed

cannot pull any more fuel than it is currently

i can help you sort it if you would like

shoot me a email

don

[jrod2smooth]

thank you don will have another log in a couple of hours, adjusted the idle and Minium spark table to see if that helps any, the two tunes are so different its very hard to tell what is letting it idle on my shitty tune i made vs sprays tune. Oh and FYI to anyone that cares I blew 2 pistons and sent a rod thru the bottom of the block, with Christmas and this motor a brother is tapped hint "help a brother out" lmao.
