Livernois Tune Madness on "Winter Blend"

[14SHOCAR]

Hey everyone, it's been a while since I've been on to chat about my tune issues. Ever since winter came about (and even sometimes in summer), I've been getting the obnoxious popping at wide open throttle, near 5k-6k RPM. I've been talking extensively with people who have Torrie/Unleashed Tuned vehicles and they don't have popping what-so-ever. I also hear that Livernois came out with a v9 tune, which makes the popping issue worse.

I don't completely buy the "winter blend story" shouldn't the car compensate with it's fuel trims based on air density, temperature, and octane? Does spark blowout generate misfire codes? The only code I have is a steering angle sensor code, which keeps me wondering what is going on.

I also want to get a running list of people who are having this issue. I'd like to take it to Livernois and say I'm not the only person having this issue. They insist they have the tune installed on 100s of cars without issue. Its hard to believe. If you have an issue with popping what year is the make model and year of your ecoboosted engines.

Thanks all.

Have you checked to see if the car behaves the same with the stock tune?

 

[14SHOCAR]

I'm going to load the stock tune when I take my care into the shop to get the windshield washer fluid pump fixed. lol Such a stupid problem to have with the car. 43,000 miles and they won't cover it under factory warranty.

Might want to check your plug gaps, I haven't had the 15 checked but the 13 was all over the place.

 

[14SHOCAR]

Here's the kicker. The plugs were "pre-gapped" from Livernois. > : ( perhaps I should ask kindly for a new set.

Did you verify the gap before install?

Were they SP-534's?

 

[14SHOCAR]

Gap was around .030-.032 on all of the plugs. I'll have to check the model number.

Brenton,

Is this still with e85 blended fuel by chance?  If I recall you said this issue came about after adding 1.5 gallons of e85 with 93 octane which we personally do not recommend to do in an EcoBoost vehicle.  We have not had a single car here on the dyno making any popping sounds nor have we had customers reporting back their car pops after they've loaded our tune. 

Minor spark blow out will not cause misfire codes that we have seen.

Why take it to dealer for the windshield washer pump?

Especially out of warranty?

It's a 10min DIY job! Crawl under the psgr side of car, unfasten the smaller under belly pan to gain access, reach up, unplug wiring harness to pump, un-snap the pump from the plastic tabs formed into reservoir, replace with new pump.

Wallah!

Oh, & I've never experienced these popping issues that you speaketh of....

FWIW to your numbers tabulating.

Popping sounds could be "backfires" through the intake manifold also.  Check thoroughly for loose/split hoses/connections.  Do you still have the OEM intake?  Might be worth putting that back on and seeing if there's any difference.  The K&N might be magnifying these sounds.

I would order a new set of (COP) total six needed and ba fairly cheap alternative which might fix your issues,sometimes the boot gets ripped due to heat and the spring inside overtime gets corroded because of moisture buildup and can cause misfires,a failing coil may cause the engine to backfire to emit a (loud pop from the engine)during sudden acceleration or even cause the car to shudder and will experience poor mpg.  Z            http://www.rockauto.com/catalog/moreinfo.php?pk=3422364&cc=3300371&jnid=485&jpid=0

Have you logged it to see what is going on?  Watch fuel pressures, misfires, throttle plate position etc...when it happens and then you will at least have a clue what is happening assuming you have the capability to do so.  Use Forscan on a phone and get an MX adapter for the best resolution. (assuming you don't have an SCT handy since you are Livernois / Mycal customer) It's a good investment anyway to know what is going on with your car...

Only time I had popping noise was when a small pressure line that had no clamp on it came off. I had an over boost code.  Dealer replaced the hose and added a clamp. The car also ran like crap.

Good idea... But maybe just run a vehicle health report first.... Might be some info there.

I think Brenton is to busy focusing on his new anticipated video in the works exclusively on Tangents Daily so do subscribe,Btw did you make a video on the popping madness from hell part 3,at the very end its all about the ratings.lol.  Z

I log around 30 PID's when I log. I don't see how you can do that without SCT. And to be thorough when trying to diagnose something I would log as much as possible.

I would be interested in STFT's, measured AFR,  Actual throttle angle, Fuel pressure at the rail, Misfire count, Knock senor, TIP and MAP pressure, in addition to normal things like RPM, Coolant temp, gear, IAT's, vehicle speed and spark and cam timing intake actul..

Popping can't be good and means something. I doubt the higer E would be a problem but the more you have the more your stft's and ltft's would read.

 

[bamsho]

It's cause they put butane in winter gas so I helps to vaporize more easily in winter.  Summer blends don't do it.  Also +13 cars seem to be more fuel sensitive than the 10-12 cars.  My '12 didn't do it, but the '13 does.  I've changed plugs, coils, tighten clamps.  Not panicking here.

Have a local buddy who was experiencing a little "breaking up" during WOT at high rpms...finally got him to load the 91 V9 tune. All is fine on that file........

What MY vehicle is he running, SHOnUup?

Yeah, I have a similar issue, but only when on the highway (60-80 mph), and do a hard kick-down to pass. It bogs down a couple seconds, blow out some black smoke, then starts to get moving. This started with 93 performance V4 on my 2015 XSport. Never had this issue with V3. Stock plugs were gapped at 2000 miles to .030", now at 18000 miles.

Straight line acceleration is fine.

I was told winter blend and try dropping the tune down to 91 perf v4.

I just switched to 91 perf v4 and it did it to me again. I'm going to try this one a little longer to see if it keeps doing it, then switch back to 93 perf v3 and see how it is.

I have always run the same (busy) station 93 Shell fuel.

On top of it, I have also been having issues with my tuner "programming interrupted, return to factory settings" (which takes about 6 tries to get to. Just received my 3rd tuner (first 2 had the same issue) which has worked going to the 91 tune without issue so far. Anthony has been great with helping me out with the tuner issue.
