Hey guys, I'm new in this forum but given that it is strictly Elantra oriented I thought it would be the best place to field my question.

I own a '10 Elantra Touring SE (Beta II like the sedan) and I've fitted a Apollo CAI and a custom cat-back. I am looking to get the most out of these bolt-ons, and have considered going with a custom tuned Unichip (I live near Cinci and there's a custom tuner nearby).

Obviously, I'm not expecting huge gains here from a 2.0L NA, but I did have sort of a newbish question since I'm new to tuning the ECU. Is it possible to opt for just putting your car on a dyno and having a tech hook up to the ECU and tune (AFR, ignition, etc.) it that way, rather than blowing the extra dough on a custom tune for a piggyback (i.e. Unichip)?

I'm looking foremost for those with actual experience tuning their ECU, please, but all (constructive) comments are welcome. Thanks!!

To be honest you are the first person to try that on anything newer than the 06, let alone non-turboed at that. It is my belief that the ECU would have to be reflashed to get those changes made (or in tech speak, remapped). If your tuner shop can crack it and get the maps for it and offer a custom tune I can guarantee you for the right price many HD (07 and newer) and Touring Elantra owners would be all over that (especially since the restrictions to modding that is on the car).

I say do a test run with hooking it up and trying to tune it, if not, see if they shop can pull the map and go from there (just make sure that they will be willing to insure your car if anything were to break that would hinder the car's stock performance).

Good luck with it and keep us posted, I am very interested in the progress.

I live in Richwood (just south of Florence) and work at 5/3 downtown. Usually travel down to Lexington for meets and such. Doesn't seem to be too big of a scene up here. Thanks for the welcome.

Well if you get the tuner shop to do a custom tune go for it, I am not sure about UniChip for i have never heard of it over here on my side of the fence. But if you want to look into the other one PowerAxel they can flash ecu's as well. I can't give you any feedback on them until after i rebuild my motor.

Awesome, I'll definitely take a look at the PowerAxel. Has anyone tried the other piggybacks like the AEM EMS with any success?

Edit: Just took a look at the reflash on PowerAxel's website and they only have one for the Gen Coupe right. Sent an email inquiry about development for the Beta II motor.
streetfighterguy
AEM is just a bit pricey but i am looking at the Unichip site right now and i am about 70 miles from a tuner that deals with them so i will give them a call to find out what they can do for an Elantra.

Cool. I called the one in Cincinnati and they said about $825 for the chip, installation and custom tune with dyno pulls. If you find anything else out I'd be interested to know.
streetfighterguy
They said the chip would work in the Elantra?
slowgls
thats cool.

I told him (the tuner) what type of car I drove, and he said they would have to do the "hard-wire" tune (no harness for the Elantra so it is spliced into the ECU harness). If you look at the Unichip site it says that is a universal piggy-back so I wasn't too surprised to hear this from the tuner, but I still don't know what to expect as far as gains. I also know that many Elantra owners have had the chips installed too, but I still haven't heard from them yet.
streetfighterguy
Many elantra owners... I am still waiting for one to pop out of the woodwork and recommend something as well. The only thing that you can really do is spend the money for a reflash, get a stand alone unit or a piggyback. But i think i should wander over to a tibby forum to ask around from the I4 guys over there to see what they are modding with.
streetfighterguy
Well i think most of the Tibby guys are working with the ngm kits for tuning their ECU's http://ngmhouseofpower.com/

Check out what they have on this site you might find something you like.
Vampyrate
while they are the same engine, i wouldn't go with tibby tuning unless you have the transmission and other mods to deal with it (gear ratios mainly). while it is a good starting spot, let your shop know that you have the same engine as the tiburon, just with different gearing ratios and start from there
streetfighterguy
If you look on the site they have this nifty little hand held flash tool for 500 that you can get from them with a few different tunes pre programmed into the unit.

I guess this is the device you're referring to? http://ngmhouseofpower.com/product_info.ph...products_id=322

I might inquire about that to see if they could provide me a map for the newer HD/FD's Beta.

Edit: Just noticed that they didn't have an NA map available for the Beta engine. This might be an issue.
streetfighterguy
I would call them and ask cause i am sure they do something for the Beta II. Also they have the normally asperated one and a reflash that bumps rev limit up to 8000 rpms..... That would be silly if you didn't have the right parts in place.

Yeah, I probably will. PowerAxel's site looks a little more professional/convincing to me, and they are doing work on newer models so hopefully I'll hear back from them too. We'll see, may just end of going with the Unichip for simplicity's sake.
streetfighterguy
Yeah if the Unichip is closer go for it. But keep shopping around just to see what else you have avalible


For me the PowerAxel guy is only about 80 miles away so it really isn't going to far for me to have him flash the ECU plus his office is at the hyundai dealership
zielritter
Just an update, I've left a phone message and an e-mail with Next Generation Motorsports inquiring about getting their flash unit with a custom ECU map for the ET. Haven't heard back yet, but will post any information I get from them as it comes.
streetfighterguy
Yeah i would like to hear how that turns out for you cause cracking the ECU on this car seems like the Bane of everyone.

Wouldn't it be cheaper to purchase a reflashed ecu than trying to get it tuned?

Maybe, but the problem is that there is not a reflashed ECU for my car. Hence, the inquiry to NGM. Also, another update, I may be considering going with the AEM FIC 6 route instead of the Unichip. The AEM piggy back controls ignition timing and AFR like the Uni, but it can be had about $150 cheaper.

Also, there appears to be more dealers/possible tuners for this module, which will allow me shop around for the best install/dyno price.
streetfighterguy
Interesting, i will look into this setup as well considering there is a shop about 10 miles away that could do the AEM tune. More options, but i am still waiting for the quote on the engine rebuild before i get the tune.
zielritter
Well, after getting feedback from tuners and other forums I've posted on I've decided to scrap the ECU tune for the time being. Most everyone I've talked to said the bare minimum you need to get anything out of the tune is an I/H/E setup for an NA car.

I've got the intake and exhaust portion, and I went ahead yesterday and ordered the i30 header from sharkracing.com. For those who don't know, the i30sw is the Touring's European equivalent. The i30 hatch and sw wagon are identical under the hood given you shop for i30 parts fitting the 2.0L and not the 1.6L or CRDi engines we don't get. sad.gif

Anyways, after I install the header and o2 simulator I'll post pics and set up a garage on this site. I've been at Hyundaiforum.com for a while, but I like the feedback I'm getting here regarding performance parts. Maybe I'll stay a while. wink.gif
streetfighterguy
Well i have a header that i pulled off Ebay for about 120 dollars and you know what? It works great and i don't have issues with the O2 sensor after i welded the rear bung into place behind the new CAT.

Like the guys over at EXD were saying is if you want to buy the ECU for the NA system just get one that can be retuned for turbo later on the line if you want to take that route. You can build a motor anyway that makes you feel happy so just have fun with it as you go forward.

I just installed my i30 4-2-1 header this weekend. Had to weld in the bungs for my two o2 sensors, and I purchased an o2 simulator (screw in "fouler" type) with 3 different inlets with varying diameters to choose from in order to fool the second (post former cat) sensor.

Everything fit perfectly and the new header is significantly lighter (and prettier) than the heavy cast manifold I removed. I got the dreaded CEL with the first size inlet I used, but I switched to another size and the CEL's been off since. Let's hope it stays this way.

On another note, my mpg's have shot up (with the CEL off) significantly with the header. On a 30 mile highway drive at 70mph I was getting 37+ mpg whereas I usually get between 33 and 34 on the same stretch. This was an unexpected, but nice, side effect.

Also, I'm definitely getting a 17in resonator put in next weekend to quell some of the raspiness on acceleration. After that I should be golden. Will take pics when I get back in town next weekend.

Check with your tuner before buying any engine management system to see if they will actually install and tune it as i bought a unichip and the two authorized tuners wouldn't do it so i contacted the head office and they where no help either.
So if your not going to major mods maybe just a Digital Fuel Adjuster like http://www.jaycar.com/productView.asp?ID=KC5385

I was looking at something like the AEM Plug & Play piggyback Fuel and Ignition Controller (F/IC) kit ? http://www.aemelectronics.com/engine-manag...roller-f-ic-12/

Man, that digital fuel adjuster is really inexpensive! does it actually work correctly for our car? I'm really not looking to go FI at any point so all I would be doing is fine tuning the AFR for my bolt-ons. This would be perfect for my application if it's functional. Anybody have any experience with it?

For anyone who is interested, I've uploaded some videos that let allow you to hear my current set-up. I know there aren't many, if any, Tourings in the U.S. with the modifications I have so let me know what you think. Hopefully, some time this fall I'll get a custom tune wink.gif

Did you have cel codes when you got the extractors fitted ?

I purchased one of those mechanical o2 sensor foolers for the post-cat o2 sensor (basically like a spark plug fouler). It has three "jets" with three different diameters. The first one I tried gave me a CEL, but I switched to another size and have been fine for several days now.

I'll keep you updated if and when I get another code. Also, as a side note I've read that the second sensor only reports to the ECU if it thinks the CAT is broken or missing. In other words, the second sensor does not have an impact on the afr trims the engine uses.

I know that my mpg's didn't seem to take a dramatic drop when I got the CEL the first time around, which is to be expected if the ECU goes into open loop due to a primary o2 sensor malfunction. Just my observations, feel free to correct my understanding.
XG0DZX
We have just one o2 sensor here in Australia before the stock cat which I've had replaced with a hi flow cat , i got an error code after fitting my extractors previously 91 ron so i switched to 95 ron and the error code stopped
