Then in your head if you have no idea, your gonna freak out wondering how the hell you get TC back for when you do want it. An example would be they tell you to go in under engine diag and change the "torque delta" tables, yea just max them out they say.well I knew if you did you have basically tuned traction control out of the car. They just tell you change something without saying "this is what it's going to do for the engine". I would have liked for them to explain it out for everyone's sake of WHY are you changing this and WHAT it affects. I took them from a business standpoint, ya know just to say I did, and luckily for me pretty much all of it was, ok.I know, teach me something.? But they just run you through it without much explanation, there was even some things he says they will touch on in later courses.and never did. <<- That statement is what was kind of disappointing from the tuning school Hellcat classes. One thing I would note from what someone said above, "what I am changing and why.". Obviously it's best to be on a dyno for this kind of stuff so you can see the gains instead of, my butt dyno says that seems good.ha, also there is things you can change to affect your "butt dyno" that you are not going to see in gains on a chassis dyno, such as throttle response and trans tuning. Find what feels best without excessive retard from knock sensors. I've said before there really isn't any magic AFR for each car, there is kind of "standard" you want to keep in range (AFR), NA engine, boosted, nitrous and such but really with your own car you are just going to have to mess with it and see what works. That's where I get a little confused, do you tune for afr or tune to avoid knock?To sum that up I'd say.both? Running to lean can bring on spark knock even if you haven't changed spark from stock. what's the best way to tune and make adjustments? I will be installing a wideband in the near future, but until then. My take away from that is since I'm stock cam, ANN will be staying on. Just read the ANN thread- wow that's a lot of confusingly good information. It's a long term project that keeps making you smarter. After that you can start bumping up spark to add more power. There you start targeting your target AFR and you want to have a wideband in order to verify that you are hitting what you want. After that, you can get into full throttle tuning. After that, you start looking at your spark tables and scanning for knock. You want to get your fuel trims down to around +/-5 or less if possible. The nice thing about that thread is that you can leave NN on and just scale the injectors to get your part throttle dialed in. Then I make another change for the ride home. I make a small change, drive to work and then check it out. Just be really patient and make one change at a time and study whether you got the result you expected. If that makes sense lolYeah, I'm the same way. Probably what I'll do is data log, look at it and have someone give me a quick example of what needs changed and why and I'll come back with the next. If someone explains to me what I'm changing and why and I can look at it on the car files I feel I'll learn. I think once I get into chance things and look at them I'll do better. Just trying to get a good foundation for starters. Thanks, I have a few other threads I want to read too, I'll work my way through that one. I also really don't have all the extra money sitting around to buy the tuning school courses, I'd love to do them, but I can't afford it right now. Just trying to gather as much information and knowledge as I can before I do anything and to help interpret what data I've collected from my car. Do you have HP Tuners? If you do have you pulled the tune out of your car and looked it over?I do have an HP and Ihabe scanned it. I think the tricky part, even for me, is when someone has invested years in tuning and schooling you don't really want to just dump everything online for others to benefit from for free.but, like on this forum if you do have an issue or two with a tune you are working on usually you can get help to get it figured out. They only have Hellcat courses but, the tuning does carry over to all the late model Dodge stuff as far as ANN tuning and other things. Dodge is probably one of the more hard to learn and find info for, there is a ton of good posts on this forum, all else fails, check out the tuning school. ![]()
