When will someone have a performance programer out for the R-spec. i had one for my charger daytona and they are awesome. it got rid of the ESC, change shift points, etc. to maximize performance. Diablo had a great one out for the charger and i would think someone would have one out soon.

We should see if we can get enough people together and contact COBB Tuning and see if they can do something for us. There is a small problem however, that all of our ECU's will be different because of year, package, and engine. Not to mention the 4.6 is out the door for the future.

However, my friend has a WRX with a COBB Tuner on it. He gets 30MPG on cruises and like 12MPG and more boost when he wants it....

The big problem is that there is not enough demand. It takes a lot of effort to reverse engineer the code. Hyundai has not released the code that I know of.

The other problem is that there are not that many R-Specs Genesis sold to begin with. The 5.0 GDI has only been out 2 years. Then assume that only a VERY small percent of those would ever give up the warranty to have a tune done. Remember that most Genesis owners are not going to race their car anyway.

So when you look at the numbers, there is really no good business case to spend that kind of effort for what, maybe 1 or 2 tunes per shop.

It is not like my Corvette where the code is open and a lot of owners have them tuned. That is why there are many shops that can tune the LS engines and transmissions.

using a hand held programmer you back up the original tune on car. Then you download a pre set tune or do one yourself through the programmer. When you take it to the dealer you put the backup original tune back in and dealer has no idea you tuned it. Did that with my charger for 4 years everytime i took to dealer i took out the tune i did and put original back in car to stock settings.

Also i have seen programmers out there for Grand Marquis and other cars like that, so if they have one i am sure we will get one soon. I mean really who is not going to make one for a car with 430hp just give me one to disengage the esc and i will be happy.

We use to do this all the time. The problem is that the manufacturers got wise to this.

I don't know if Hyundai does this, but I know on the C6 Corvette, every time you upload a new tune, the check-sum gets changed and recorded in the ECM. If the Chevy dealer checks the check-sum and it does not match what is in their system, they will void the engine warranty.

GM started doing this on their diesel engines first because of the insane HP people were making with tunes and blowing up the engines and transmissions. Now all GM cars have this. If a car comes in with a blown engine or tranny, it is the first thing the regional rep checks before signing off on the engine replacement. So even a "friendly" dealer can't replace an engine or transmission under warranty that has been tuned.

You're right. the Genesis does monitor if you tune/reflash it/restore back to stock. the computer in this thing practically records EVERYTHING. once they plug their computer in, everything that is not normal is flagged.

PINGGOLF (non-participating member for the forum) said that when he did the ESC mod found on this forum, that the computer stored data and the Hyundai tech discovered this info when in for a CEL.

Don't know what to tell you did it with my dodge and others with chargers said that the dealership could not tell they had it programmed before. you are taking out the aftermarket program and setting car back to stock. Never once had an issue with the dealership.

it is not like you are keeping the tune in the car, you are completely taking it out and replacing with stock setup. the Dodge computer could not read that it was ever on there. the reason they found the ESC mod is because he left it that way and didnt change back to stock.

Yes, that is true, however, there is a part of the ECM on GM vehicles that record re-flashes. Even though you are putting the original tune back in, the ECM records that it has been re-flashed. I don't know about Dodge, but it is a issue with GM and maybe Hyundai and others.

This is why I use a separate chip on my Tahoe, I just swap the original back in when I take it to the dealer so they don't overwrite my pro tune. I don't think the Genesis is popular enough to get a programmer made for it, I've looked.

OK that is still a theory for the GM gas side, i dont know about diesel because you can run off a standalone and not even touch the ECM.

"counters" or checksums within the ECM programming itself that are changed whenever you flash any part of the tune. But you do know i real tuner can over come very easy.

And i mean come on GM is all about power you can order a corvette and have it tuned by GM performance and still be under warranty. And i know form personal doing it.
