Interesting ZSHO. I'll have to speak to LMS regarding that.

Shoboat u may need medication for a busy mind lol...programming changes all the time during a run of the same body style nothing new there..that why there are many different strategies

Ur tune may just need a tweak due to something being slightly different than last season...or let the sensors do what they do and work for u....sounds like u are reaching for some wierd reason causing a slight quirk....maybe it's time for lms v9 tune lol

We sometimes like to experiment with our cars and get a true feel on how maybe the oil,fluids look and smell like,nothing better than getting familiar with your car and sometimes even dirty,its a thing called (manual labor)something to take into consideration when your warranty runs out.Z

Most of my warranty ran out when I got home and tuned it...its served me well to do my own work and stay away from dealers...my cars never seem to break Dow tho....maybe luck or maybe from my dirty hands lol...I have a lift so I don't really need anyone's help lol

LOL ZSHO. I do like to work on my cars. I guess from my old days of being a mechanic. But I did a little more messing around last night, I tried the 93 base tune (no mods) and swapped the map sensors. Still had a misfire, however after resetting the adaptations is was gone. For a while at least. I wonder if the dealer when I was last in a few weeks ago did an update? I will get with LMS today and see what they say. Interesting that it was gone when I first reset the adaptations.

I'd definitely check on that... if you wrote down your original strategy code you can just ask the car for that code using the MyCal engineering mode... If the dealer updated it you'll have a new SW ID and a new strategy code.

I do know that the '13+ have forward and backward learning, so you can flash any tune... but it might act unusual.

I guess the best thing to due is to check to see if your strategy code was changed with your tuner device.

AJP turbo · April 08, 2015, 11:13:07 AM

If they did an update your car wouldn't run unless u swapped the 3 bar.....and when u did ur reflash u over write the dealer flash...khdl4tv does have an update...I'll have to look when I get home what it changed to...its useless tho....literally 1 change in the entire tune and has to do with communications

Hey BiGMaC, you wouldn't happen to know how to enter the Engineering mode on the MyCal?

I have the previous generation MyCal, part number 45002.
For that one:
-put the car accessory mode by pressing the start button twice without applying the brake...
-connect the MyCal while you a press the "N" and "Up" buttons as you plug it in....
-let communication start...
-on the MyCal, scroll down to ECU CAL/Strategy Code and then press the "Y" button and follow the prompts

Hope this helps

Thanks! I also have the older version.

Actually it will run... I flashed mine back to stock and like an idiot didn't change the MAP back to 2BAR one time... runs like a dog when you put it in gear, but started right up and I drove it about 30 miles before it dawned on me what I had done... acts like it's in third gear all the time on surface streets, but runs fine on the freeway.
If you discover a new update on your ECM, check your service invoice to see if they registered an error and changed the MAP as if it were faulty.

AJP turbo · April 08, 2015, 02:47:59 PM

I suppose it could run.Mine idled really bad and I wouldn't even have thought to try and drive it....I guess I call that not running....ur O2 sensors were driving ur car at that point lol...fuel trims would've been maxed out because the fuel table and speed density values would be all wrong with the slopes and intercepts....
