    Hi, Video shows everything. In general: 1. There is SOFT CUT instead of HARD CUT, what implies **** problems. 2. Redline is 6800 instead of 7200 3. Sport mode shifts very early - have read it's normal in this car but shouldn't sfr tune change it a bit ? My car is in Europe so things are not...

    Going to try and sum up everything to date to answer all the basic questions, so I’m sorry if this ends up being a lot. 2012 Hyundai Genesis Coupe 2.0T R-Spec 6speed Manual – Only bolt on mods so far, stock internals, factory sensory, and no modifications made to the engine control harness...
  3. Engine 2.0T
    Just tried swapping a buddy's canned tuned ECU into my car only to find that it would crank but not start. So, I put my original ECU back in but now the ESC and ABS lights are on permanently. Tried disconnecting the battery for 5 minutes and turning it back on, and tried doing the key dance as...
  4. GenCoupe Build / Projects
    Okay, I took a wrecked 2013 Coupe 2.0t and removed complete engine, 6spd Trans, ecu, and engine and body harness and swapped it into my bagged mazda b2200 lol. Engine and tranny went in smooth. Harness was not as fun but it's all in and wired up. Here's the deal... when I turn the key it will...

    I just got this gen and it seems like they used to have a bigger turbo or something in it because when I touch the gas peddle, the rpms jump up but not much is going on with the speed. It’s a little unsafe because I start off super slow. I also found a ecu under the floor in the trunk. Would it...
  6. 2.0T Discussion 2008-2012
    Hi, I recently bought a used 2011 Hyundai Genesis Coupe 2.0t. We know that it is tuned, but not who tuned it. The CEL light never comes on (even when starting the car), and despite a lot of effort from our garage the O2 and CAT readiness sensors will not set. We assume these are both from the...
  7. Engine
    I have a 2011 Genesis Coupe 2.0T Base Timing chain snapped 10 months ago, got deployed and then came back to get it fixed. The Engine has been rebuilt, gas tank cleaned and added more gas. Oil filter, oil pan, etc all good. New ECU because my other one supposedly was short circuited. Parts...
  8. Engine
    So I'm currently running rough on my Genesis Coupe. The stock ECU has a tune on it. I can't get ahold of anyone to tune it back to stock to save my life. Im pretty sure the engine is done. Could I just purchase a different ECU with stock settings and send it to the dealership? Would they look...
  9. Engine 2.0T
    Hi I’m new here, just bought my first genesis! A 2010 2.0 with a few mods to the exhaust intake and BOV. Engine has just under 100k, and after talking with the guy who sold it to me I found out the car was never tuned, before it after the mods. Today the check engine light came on and I used my...
  10. What is This?
    As I mentioned in other post, I use to work for Chrysler. We adopted a system called "poke yoke" the Japanese use. Basically we use white paint pens to mark a part that we visually have checked that the person before us installed (or whatever) and did their job. If you look at the picture...

    I've been lurking the forums for a while but I might as well post my first thread. I've owned a 2013 Genesis Coupe 2.0t base for a couple years now, and despite some shortcomings (and bad luck with the car) I love it and I want to keep it for as long as I can. It also happens to be my first car...

    Took my gen coupe to Hyundai because car has intermittent starting issues. You can read my other post on it. My question is Hyundai sent me the problem with the car but I don’t see how the PCM/ECU can malfunction on one thing but still be able to operate the car. Can anyone explain to me what...

    I want to get my car tuned but I want to keep my stock ECU untouched. Does anyone know where I can get a immobilized ECU that will work with my car? I have a push button start too.
  16. 2.0T Discussion 2008-2012
    Hello, I live in Crestview Florida and I am looking for a reputable tuner that I wont have to drive 6 hours to get to (I have a 2012 coupe 2.0t). There are three shops near me, but I am not sure if they are reputable gen coupe tuners. They are Adams Automotive in Crestview (review says they are...
  17. Engine and Drivetrain
    Hi all, I tried searching and couldn't find any threads on this ODB2 scan tool I stumbled across. I am wondering if anyone has any knowledge on the ECU re-mapping, custom tune, or the programming of the ECU with custom data sets? The reason I ask is due to this guy right here...

  18. 3.8 V6 Discussion 2008-2012
    Hi, I'm pretty new to THIS forum but have been on many others. So straight to the point. I bought a pre tuned canned ECU from BTR and had some problems with it. I installed it correctly several times, reset it, the brakes thing, 5 mins with battery off, EVERYTHING and it still wont start unless...
  19. 3.8 V6 Discussion 2008-2012
    Ive gotten a lot of mixed answers on the topic. I have a BK1 3.8 AT with immobilizer. Some people are saying if I buy a used ECU and then SFR tunes it, it will work no problem in my genesis. Others are saying it will not properly work(even with a tune) because the VIN will not match my cars...
