A tune will void the warranty you have, id put it back to stock, all you need is the stock airbox. I might have one in my junk pile.
The warranty I have is the “Ally Extended Warranty”The Ford warranty is good anywhere in North America.
Thats generally sold by GM dealersThe warranty I have is the “Ally Extended Warranty”
Yeah… bought the car at a Chevy dealershipThats generally sold by GM dealers
Wow thank you for such an insightful response! Couple questions here if you don’t mind helping me out a bit.That is NOT a No Tune Required JLT CAI. The dealer that told you the car is stock lied or has no clue about the simplest things. The peddle commander as well is NOT a factory device which again makes the car no longer stock. Chances are that the tune on the car caused the cylinder 8 failure to begin with. Over aggressive canned tunes (for no softer term) are notorious for causing this to happen prematurely.
You should count yourself fortunate that the dealer covered the engine replacement under warranty. Again assuming they are NOT a Ford dealer. Had you taken the car to a Ford dealer (and if you did I want their named PM'd to me so I can use them in the future) they would have popped the hood, seen the after market CAI, scanned the PCM (ECM) and seen that the tune had been modified and told you, "sorry Charlie" with regard to any remaining Ford factory warranty on the car. JLT does make what they call a No Tune Required CAI but it looks nothing like the one on your car and is enclosed and has a smaller MAF housing tube so that proper air metering will take place with the factory tune. With the CAI you have on the car (if the factory tune has been reflashed) the engine will run very lean because more air is getting past the MAF than it is calibrated for due to a larger diameter MAF tube. LTFT's will be through the roof trying to correct for the lean condition if the factory tune is in place and would likely eventually generate a CEL and on a 15+ possibly a wrench (limp mode) condition as well.
As mentioned, get a factory closed airbox, remove the stupid peddle commander gimmick, take the car to a Ford dealer and have them reflash the factory tune into the car and verify that all body modules are properly communicating to each other and the PCM (ECM) on the CANBUS network. Then put the factory airbox back on the car and drive it. If you are still having issues you at least now have a baseline to work from that a reliable Ford dealer can assist you with...though there will be no warranty aside from an extended warranty you have purchased. That extended warranty may be honored by a Ford dealer. Ask. The worst they can say is no. Or contact the warranty company and ask what if any Ford dealers in your area are honored by them. Taking a Ford to a Chevy dealer for problems like this is like taking a Samsung TV to a Zenith dealer for repair.
Best of luck to you. Sorry to hear about your issues.
You’ve been of tremendous help dude and I sincerely extend my gratitude for taking time to help me out! Just a few more questions if you don’t mind. You’re my only savior right now lol1.) Ask the warranty company you purchased through. I am speaking of any Ford original warranty. I have heard that there are a few warranty companies that will cover modified cars. I am not a warranty purchaser myself.
2.) Depends mostly on who tuned it. If it was tuned by a reputable tuner like Lund, VMP, or Palm Beach less likely. Regardless if it was under a Ford warranty which it is past that now, it would have been voided in most cases. There are a few exceptions such as Roush or Edelbrock Supercharger packages that carry a blanket warranty option, but here again it only covers anything that Ford would otherwise not and is additional cost. There are less reputable tuners out there that offer basic canned tunes at a much lower price and promise the world. Additionally if being tuned on 93 and the car had 87 pumped into it that could cause issues. If the car was tuned for E85 and had 93 or 87 put in it this could also lead to problems. Not knowing is your issue. Never buy a modified car without the tuner. I passed up several nice cars looking for my current project because they were modified beyond what I wanted, undocumented on the mods performed, or missing the flash tuner device.
3.) unlikely none. A rich condition would likely be observed which would be seen in trending LTFT data more than likely. A rich idle would also be likely observed.
4.) Hard to speculate. It may simply be that they have reflashed the PCM to the factory tune and with the mods it only now appears to be corrupted. But it is possible if the voltage on the battery was low when they reflashed the factory tune loaded but failed to load properly. The 2015+ cars are very picky about voltage when being flashed. In fact the guys at the speed shop I deal with will not reflash or load a tune update on a 2015+ unless they have a charger hooked up to it to ensure voltage stays up and does not sag over the very long download process compared to earlier models.
Sorry cant be of more help.
2. I have never seen E85. What is that? An octane level? And why would anyone want such a low octane?
You’ve been of tremendous help dude and I sincerely extend my gratitude for taking time to help me out! Just a few more questions if you don’t mind. You’re my only savior right now lol
1. I definitely considered the possibility of gas octane levels affecting the car. Since I’m at a guess right now till I get the factory air box and reflash the tune which of the 4 octane levels (that I have seen in my state - New Jersey) is MOST likely for the car to be tuned for? 87, 89, 91, or 93? In other words, if you had to take a guess since there’s no other way of knowing, what gas is most PROBABLE to cause the least issues?
2. I have never seen E85. What is that? An octane level? And why would anyone want such a low octane?
3. What is LTFT data?
4. In regards to your answer in #4, there has been NOTICEABLE voltage and electrical problems with my car. I’ve replaced the battery twice since having it for 9 months. Is this indicative of anything?
5. In regards to the dirty intake filter, if it wasn’t properly maintained and cleaned couldn’t that “sandblast” the engine and possible cause a misfire? I’m terrified that if I don’t resolve this ASAP I’m on the road to another misfire!
6. Instead of reflashing the tune and installing the factory air box, can I just get it “retuned” or properly tuned somewhere?
7. Assuming I have an overly aggressive CAI tune running or some corrupted tune (which I think I have one or the other) does my driving pattern affect the probability of causing any issues? In other words, if I drive slow and smoothly instead of aggressive and fast will this help prevent any mechanical problems/issues? Or is it just a matter of time until a problem is created?
