Anyone know when these ECU updates came out and what they involve??


295 FS 1.6 DCT P0456/0461/2192 DTC LOGIC IMPROVEMENT
294 RB 1.6 AT P0456/0461/2192 DTC LOGIC IMPROVEMENT

I know some of you on here have said something about the gas peddle having lag and some other things that maybe an ECU update could fix. Maybe these just came out? Anyone have any more info on these updates to the 1.6?

I never heard about this at all. I know we have clutch lag on the MT, so by solving that is to disconnect the ECO plug right about the clutch pedal.

OOOOH. Logic improvement sounds promising.


Tell me this leans the mix out a TINY bit, gets rid of the soot, increases MPG, and gives us a smoother powerband...hey one can hope right?

I wonder what this is. Any idea when it came out?
I'm assuming this is a go to the dealer update if you have the car already?

Thats what im guessing. I just saw them on the hyundaitechinfo.com site and would love to have more info about it. If it clears up that soot issue that would be great... but i think that has something to do with our emissions and how hot the Cat gets.
There is some info on this forum
Altho it's for Accents, thread 11 and 12 mention DTC codes on our engines

Ah thank you. I knew someone would know something or at least may have found these already.
Kind of interesting that they have a "system too Rich at high side" issue on the accent with the same motor yet have not addressed it with our variance... even the N/A are seeing the Soot problem...
this update was released in january 2013, i'm a tech at hyundai. those 3 codes are p0456 evap emissions small leak detected, p0461 fuel level sensor "a" circuit range/performance p2192 system too rich at higher load. this update isn't really related to anything its just changing the parameters at which these codes occur. these motors also have a problem with the purge solenoid freezing up in colder weather for the evap leak, the fuel sender unit code is what happens when you let moisture into the vehicle, the cluster will stop working and that is the only code that appears, this update is also for this so the code does not show when this occurs.

So take it to Hyundai so they can update it :D?
yeah pretty much i've done about 8 of these updates and honestly it takes about 2 minutes.
