Someone on another forum mentioned the only reputable company making a performance chip for the Hyundai's was Powerchip. I looked in to it, and found out that it's nothing to make a snap decision on. Without knowing more than that basics of what performance chips do, has anyone ever had the Powerchip (or for that matter, any chip) installed? Worth it or is this a just a money pit?

Not a cheap one either, at $490... and this GT+ Tunerbox i see some people talk about that's on eBay for 25 bucks has to be a piece of junk... right?

There is pretty much no plug/play solution for Hyundais because they have a difficult computer. Everything you will see good gains with is going to run a few hundred dollars and require at least a laptop to tune. Plugin resistor modules != power adder. Go for bolt-on modifications first.

I wasn't planning on even worrying about the chip until after at least a CAI, but I was interested. Powerchip is still the only company I see to go with, is there a way to reprogram the ECU with just a laptop and some software, rather than sending the entire ECU off (seems like a hassle)?

i have seen a few member's have their accent 1.6L ecu done by powerchip but gains were marginal,

probably about 3-5 HP gain..but drivability and powercurve were much smoother,

for $490..you can get a Intake, header and exhaust and pick up abot 5-7 horsepower
and take out your spare, tools and back seats, it'll make the car lighter and handle more nimbler...

There is no where near enough support in the Hyundai community for the 'big dawgs' to make tuning software for the ECU's. Its unfortunate but ultimately the truth. So atm to my knowledge there is no 'self' tuning software out there.

powerchip is a great company i know one of the owners Dennis Johnson u get around 10hp but its smoother and runs way better if alot of people want chip i could ask him for a group buy and it would be much cheaper..Also i have talked about a tubo chip which they will do but they would need at least 30 people thats want a turbo set up..

ok. I live in South Africa and you get Powerchip here(imported).. not bad. I opted for a complete stand alone system. works good on my 98 tib. but on the newer tibby's with more "brains" in the computer box... not a good idea. alotta guys here install SMT6 to their late model Hyundais. not a bad system at all. maybe its old news to you guys already since we still in the stone age here...? dunno.

Yeah, I'm not heartbroken or anything, I really just wanted something to run my intake, exaust, and other mods as best they could be run, figured a chip would be the best for that.

I have the Hyundai Loader software but I have no idea what software to tune the chip with and or the cable to hook it up to car. From the reading I have found they are bosch me7 clones basically very similar to those in bmw's etc. Not alot of people want to touch these ecu's in Oz that I know of one place only.

dude
since you have a tib, look at Haltech.

the interceptor or miniceptor.

these are "PLUG AND PLAY" as have base maps for the excel and tiburon.
you can alter air, fuel and ignition stuff to add extra power, and the best part is that all you need is a laptop as it comes with software and data cables to allow you to modifiy and make changes at home.

however i reckon for the "first time" do it at a shop.

also you can have 2 maps on the ECU and switch them over when you want to by a simple switch.
e.g performance mode and economy.

have a look into it.
Interceptor - Haltech Engine Management Systems

RPW is a place that sells them for hyundai and mitsibushi

Those look nice, and I would like something that allows me to tune via laptop, but both are over $700USD... for that I could install the Powerchip ($490) and then some. Wasn't really looking to go that high for just the chip.

Also, if I did go with that chip, the compatibility sheet says its only compatible with the '04 I4 2.0L Tib, mine being an '03 V6 2.7L, would that even work?

As far as I can see from the site, Unichip does not even make a chip for the '03 Tiburon, but if you know of one, feel free to pass it along!

one of the problems with a powerchip or similar ECU reflash is that once the changes are made, that is it.

so you could set it up for power to match your current mods, but for any reason that you change something, exhaust or intake, cam timing, fuels whatever the powerchiped ecu will be reading wrong thefore not making the best gains for your set-up.

the haltech on the other hand is able to be changed very easily and at no cost to you (if using a laptop).

the way i look at it is long term, $500 for powerchip now, and maybe a couple of years later when you upgrade something another $500. or if the situation changes... another $500.

OR

$700 now and the ability to do what you want with it, advance retard ignition, change air maps, fuel maps etc to suit what you want to do with it.
Hell you can even set up maps to allow for nitrous, i'd like to see the powerchip do that !!

$700 for life or as long as you have the car.


AND, you can eailsy remove it and revert back to stock if you sell it, with the powerchip once you reflash the ECU, that's it, you cannot return to stock at all.

food for thought

That's a good point, I hadn't thought of that. I never had any strong convictions toward the Powerchip really, it just seemed like the only option before I found out about this one. Honestly, I really would prefer that one, it may just be a little longer because of the price. Even with the price, I'm glad to know about it cause the variety of options for chips seems slim.

IMO, Haltech is not worth a damn (and trust me i've had expirience with them all). For the cost of a haltech I'd rather go with a Megasquirt. Its alittle more 'advanced' up front but in the end it will allow the user to learn more in-depth about how things work plus has the same amount of features (actually i think MS has more, and you can always add on).

If your only doing an intake/exhaust setup, honestly i wouldnt bother throwing the cash down for an ECU tune, Sure you'll gain alittle, but there are far better things you could do to improve vehicle performance for that cost and gain more.

I hear about Megasquirt all the time actually, never knew much about it. Where's the info/ordering for it? All I see on Google are instructions, diagrams, and forums.
