Early 2013 models have bad tune?

That may be what the flash was labeled but it would include ALL updates so would address your concern as well as several other tweaks and improvements they made. The car may seem weird for a bit while it relearns everything so don't panic.

The amount of fear mongering you've fallen into is hilarious no offense, the latest tune you received is literally the same fix incorporated into all the latest ecutek and OFT tunes. You can drive as hard as you like now. The DI seal popping issue was a very small group of people that actually got effected.

None taken, I don't really have a whole lot going on right now and my car is pretty important to me. I had heard the early 13's don't like to be supercharged and had a few minor issues but I ignored it chalking it up to minor stuff that wasn't really important to me. After seeing the posts CSG_mike was making on reddit, I did some digging and found all these people freaking out over it. So natural, I freaked out too lol.

OK here is simplified answer

Cars manufactured before early 2013 had an error in the ecu tune in that the transient ignition retard was effectively disabled above 5000.

If your ECU calibration ID is earlier than ZA1JA01C man or ZA1J A01D auto then you have the issue ie 400C/D 700C/D and A00C/D rom id.

Their is a TSB out to update these early roms to a later rom either B01C or B01D these roms have the transient retard fix and a numder of idle fix's as well.

The lack of transient ignition retard is only really an issue if you have poor fuel like say 91 in your area and you drive the car very hard and shift gears at or very close to redline (7400) quite a lot as the error in rom resulted in the transient retard being disabled if rpm was above 5000 on completion of shift when load came back on and you got excessive knock. you could still get the problem on good fuel but its much less likely as it was related to knock encountered on shifting gears at high rpm.

you will know if your direct injectors are stuffed as you will usually get loud popping sounds from intake on acceleration and maybe other weird issues poor idling hesitation etc.

If you get a tune the tuner will/should update your rom to the latest factory calibration compatible with your car which will likely be B01C or B01D although even A01C or A01D is sufficient. So this problem should not be a problem in tuning or supercharging your car as it was related to firmware in the ecu which is easily updated by dealer or tuner or yourself if you buy a tuning device

is the popping something that happens all the time, or just occasionally? I hear something that sounds like a pop in the engine bay every so often (maybe once every other week), but its not regular, nor am I able to repeat it. I am probably being paranoid here, but I hate the thought of being broken down at the side of the road for any reason. And I run exclusively 93 in my car.

usually it would be pretty regular and loud.


you get the odd pop on startup when car is cold that's normal
