OFFICIAL Seoulful Racing (SFR) ECU Reflash For Sale NOW!!!

Locally e85 is the cheapest so this would be awesome if it could be done, though you can't pick up e85 everywhere so that may be an issue.

i have a question about the a/t tunes can you take off the automatic shift on the sport mode or make it shift at 6.5k instead of 6k rpms?

Id there anything else to do other then swaping the ECU?

A/T is controlled by a totally separate computer.

Nope. Plug and play.

So best bet is getting a tune 87 and if and when I pump higher grade ill get more performance,but I shouldn't have a problem with pinging?

Pinging should only occur (in this situation) if your fuel octane is less than the tuned octane. And even then it's not a given. It's just more likely.

So how does this work buying an ECU flash online. I see the option for sending your ECU and getting a return label and also for core returns. Is everyone taking out your stock ECU, sending it for a flash, then getting it back via mail? Or are you buying a whole new tuned unit? I can't see anyone going 5 days without a car

so how is this hp increase achieved? More boost? If I order the extra ecu will I have to get my keys programmed?

no you wouldnt have to since your keys are programmed into the BCM which isnt part of this

Mine is getting tuned at an SFR event. You can have the ECU sent to you or attend an event to get one. I will probably be buying an ECU at a later date.

I think attending the events is the best way. You can actually see it being done, ask questions, talk to the owner and tuner, etc.

Sent to you meaning they would send me a new, flashed unit and I would basically return my factory ECU to them?

They will send you a new flashed ECU or you can send in your ECU and they will return it to you with the flash on it. Not a bad option for buying a new separate one, but I dont know how Id feel about mailing mine and having no car while I wait.

so did they increase boost, adjust a/f? Just curious how they got the power.

+ timing. and they havent posted it but also probably due to increased octane. generally how its done in tuning ^_^. not much else.

Hmm, I wonder how much boost? I would hate to melt that tiny turbo.

They up the boost fix the afr. Timing im not 100% sure but most likely raised

I'm sure there is negative effects of running a tune.. Your taking a car, regardless of how capable it may be, and changing the way a lot of things work in order to have the extra hp.. I'd say, this is strictly from my point of view, that your probably going to have your turbo go out a lot sooner as well as replacing some other parts that it puts more tension on.. Not knowing everything about cars I'm not sure what all parts would be affected but none the less, it's gonna add wear and tear on the car..

Thats not necessarily true. A properly tuned car will always last longer than an improper one. That being said this car runs rich from the factory which is worse on certain parts than a perfect afr. The turbo will probably not last as long though due to the higher boost but its not over spinning it so its not really a problem.

I had a tune on my Mini S it was a stock flash and it was fairly aggressive but safe. It ran fine for for 190k miles. It still uses all the same stock adaptations like it will still pull timing and add fuel when needed but it wont be set so rich and will utilize higher octane which over 100k miles is like financing $700 at the gas pump. people pay more on rims with less return in performance. No brainer for me at $450 its easily the best bang for your buck mod. 93 Octane please Edit: I swear at the end of the dyno video some guy yells "Suck it Trebeck" lol

That is a pretty poorly formatted page for information. If I select pretuned core it adds $20 to shipping, but I don't see where the cost of the ECU is?

It isn't that poorly formatted. The price for a pretuned ecu is in the first drop down menu.
