What is it and how is it done???
Does it give the car better performance? In what way does it help? -------------------- A proud member of the club.

Supposedly some people think they know how to get performance out of the engine better than Hyundai does and say they can reflash the ECU to soup up the Elantra. In the old days when ECUs read inputs from just a few sensors and didn't control that much, this may have been true. I'm sure there are a lot of people today who would like to think it's still possible.
But when you look at how strict emissions standards have gotten and how tightly cars today self monitor their settings, and how many settings are monitored and controlled, I just don't think it's a good idea. If your ECU generates an emissions-related code, you fail inspection, even if what comes out of the tailpipe is clean. Plus you're voiding all kinds of warranty if you're running your engine at settings it is not set up for. In the old days, it was pretty easy to set up a car for power (at the expense of mileage, emissions and durability). Not so easy today. -------------------- A proud member of the club.

In the old days, it was pretty easy to set up a car for power (at the expense of mileage, emissions and durability). Not so easy today. Sorry to disagrre with you Doohickie, but if you have been paying attention to the aftermarket, retuning the ECU is the easiest and most popular way to increase performance. I have seen Camaros, Corvettes, full size gas and diesel trucks, imports, you name it use this mode with great results and no warranty or emission issues. In fact, most of them are even CARB certified. Not something that would happen if it hurt emissions. Hyundai has to tune these engines for the market they are selling them in. 4 door economy family sedan. So of course they are going to tune the engine for that market. Cheapest gas possible, smooth take offs, best MPG. Performance was pretty much on the bottom of the list. By reprograming the ecu, you can change the tuning curves to take advantage of higher octane fuel and give it a more performance tune compared to the factories basic tune for the average economy car driver. This mod works so good on other models of cars, allot of times it is the only mod the owners make, or they may add CAI and cat-back to go with it. Also, in the old days, that was what made setting up a car for power HARDER. You had to sacrafice mileage, emissions, and durability. With todays technology, you can have it all. Power, mileage, emissions and durability. Stock engines today are making more horsepower per cubic inch then most performance engines of yesterday, with better mileage, emissions and durability then ever, mostly because of ECUs being used to tune them. But the ECU is only as good as the program they are fed and use to do the tuning. For old timers, think of it as changing the stock timing and timing curves of the distributer and changing the jets on the carb for best performance. Most of you know that while this may not add allot of horsepower, it definitly changes the way the engine responds when you hit the gas pedal and how it feels racing to redline. But unlike those days, the ECU can also back off that tuning a little when it notices it is not needed, which is why you can get the performance without the hurting MPG or emissions. By the way, Stringshifter just had this done to his Elantra a few days ago, hopefully he will drop in and give his thoughts. Or look for his post in the performance section.

JP is absolutely correct! The auto makers have to detune the computer to suite the marketplace. Just like back in the day they'd use 69 jets and only 30deg total timing when you knew damn well you could put 74 jets on and 40deg total timing.. The difference is exactly like JP said. Back then you sacraficed for gains, today you don't have to sacrafice anything, even if you do loan your car to a buddy who stupidly puts 87 octane in, the computer is smart enough to downsize the tuning to keep from blowing a hole in the piston, or worse.. Sure it'll be sluggish, but you won't grenade it either.. Nor will the engine ever "not" shutoff.. Anyone remember doing that way back then, setting the timing wayyy to far ahead.. LoL So if you or anyone would like more info, I'd suggest you please refer to the link JP posted.. It should answer any/all questions, and if not, feel free to post them.

The ecu retuning does not set a cel or other emissions related codes. For the most part, it is only retuning the learning maps that the Hyundai ecu uses. It has full control, just better notes to cheat off of. It doesn't touch any engine hardware and as stauf and jpjr said, the ecu will cut back if a problem is detected. It will not detonate itself. But if you do want an ecu, yea, talk to stauf. He's cool haha.

So aftermarket what hardware/software is available for tuning the factory ECU ????
i.e. changing fuel , ignition , idle load mapping points ? Sorry to revive a old thread , just did a search before I started posting a new thread on the topic. cheers -------------------- A proud member of the club.

I was working with a company here in florida to get ecu reflashes but he pulled out. There is a company in california called Poweraxel, they will flash your car there is a guy on the EXD boards that is turbo'd with a reflash from them, but you have to go to them in cali. They currently offer reflashes for the gen coupe turbo where they send you a box that you hook up to your obd-II port and hit a button and it will flash your stock or near stock (couple bolts on will help with power delivery but no necessary) ecu people are seeing gains of 40 whp and 35 tq's. The cool part is that you can go back to the stock map at any time and then there is a third spot on the flash tool for a custom tool. Down in boca roton there is a poweraxel dealer, but trying to get with him about flashing my car, but Arvin out in california is reluctant to let the software go anywhere.
i'm still hopeful though. oh, and TC from next gen does reflashes, but again you have to go to him and HE wants 700 bucks for him to tune your car....no thanks. -------------------- |

Back in Puerto Rico I had a 2010 Lancer and the Dyno Shops were doing Reflashes and they were getting up to 30hp and around 25% fuel economy.
Most of them charged you $250 but that include the dyno tune. Check this post from carrito.net: http://www.carrito.net/board/showthread.ph...ghlight=reflash Is in Spanish so you will have to translate -------------------- "You are unwise to lower your defenses!"
