I'm getting restless again now looking into getting the ECU modified as Hyundai haven't had any updates since I bought the car two years ago so should be safe to stick a new tune in it now without them re-flashing over it, if they did though it's no biggy as I'll own the tune and can re-flash again at will.

There wont be major gains...though there will definitely be some improvement in power 10-15% torque 15-20% and response by tinkering with the flyby throttle and variable cam timing settings, fuel usage will be the most improved I think and it should make benefit of the flow restrictions I've already removed with the other small modifications, just a few more calls to sort out the finer details and it might happen next week with any luck

I can well understand that you can tune for more power and torque. So could Hyundai in the first place if they were willing to suffer more engine problems during the warranty period.

I cannot see how you can tune for more power and better economy. One of the prime things people look for in a new car is economy - and in the UK this can indirectly effect the road tax you pay. Hence manufacturers all compete for better economy than rivals. I just cannot see a small tuning company being better at it that the manufacturer who has enormous resources at their disposal.

Hence I will be most interested to hear how you get on.

Good luck............

That would a nice programming to do to the car just wanted to know won't that be avoiding your warranty?

Please let us know how u get on.
Thanks

Alan, factory vehicles are tuned to a very restricted level which also makes them run rich ( leaning out the fuel automatically increases power and lowers fuel consumption as well as optimising the cam timing ) they set the tuning parameters low to compensate for poor fuel quality and so that there is less chance of stressing the engine which wont cause them any warranty issues in the future, plus the cars are built to a budget so extra time spent on tuning would add to the cost of the cars, hence why tunning companies make million of dollars out of the extra time and development they put into this sort of technology.

Being that the levels are set so low there in plenty of room to make adjustments and still keep the vehicle well within safe operating specifications, I could still add a turbo or super charger and this engine would handle it quite easily as long as it wasn't to excessive.

A few auto brands are starting to pick up on this and are offering enhanced tunes to their customers at purchase time and available at later dates ( Audi is one that springs to mind that now offers this on new vehicles ), would be nice if Hyundai did do this one day.

You'll also find that professional race and tunning companies like I'm using ( not a small company ) are some of the key developers in the technology and advancements behind ECU's and other car parts, car factories learn most of their advancements from the racing world and then they harvest that information and turn it into mass produced budget software/products and sell us the detuned versions of everything, eg chassis - suspension - brakes - engines - gearboxes - ECU's

Yes it can affect your warranty ( but who cares ), that's why I use the guys I've always done these things with and the tune itself is undetectable as it's modifying the factory ECU so if Hyundai plug in their diagnostics they wont be able to tell   piggyback tunning is no good as the factory ECU will detect and compensate for the changes done making your expense a waste of time.

Let us know how you get on then mate and maybe we can try it out

Craig has the 1.6 GDi motor. Would be quite different to your 1.4 MPi.....

[CraigB]

Yep, my tune is only for my 1.6ltr vehicle, it wouldn't even be any good for another car the same as it's customised specifically to suit my modifications.

[Raid]

Yep thought it would be then will look for something if I can get for 1.4

[CraigB]

You'll need to speak to a highly recommended speed shop in your area and if possible for your car diagnostics would have to be collected from the ECU and sent off to qualified programmers in Europe to rewrite the tune then returned and tested, then repeating the process till all benefits are made, there is no live dyno tuning adjustments that can be done for these cars so it is an expensive and lengthy process.

And that is if there is software to actually modify yours

[cruiserfied]

I really want to get a reflash for the new Jeep. Try for some better power and economy.

[CraigB]

Most tunes and custom programs are bought through VIEZU Remap, Chip Tuning, Car Engine Tuning, Economy Remap, ECU Remapping if in the UK can call direct for tuning and local installer locations, if somewhere else "like me" a reputable speed shop will already be using their tunes

If you have vehicles like the Ford and Holden's they can be tuned on dynos and don't require software from VIEZU...if your tuning specialist knows what he's doing of course

[cruiserfied]

Theres a number of companies in the states that do Jeep tunes. Just gotta decide which one and start saving.

I know a guy here that tunes the Jeep ECU's but he does them manually on the Dyno, not much good for you over in the east

[cruiserfied]

No not much good.

Spent the past 3 days doing a top to bottom engine rebuild on a petrol iload. Man it was good, taking my time checking everuthing twice etc. Took 2.5hrs just to clean and setup the pistons.
Got me wishing there was a good performance shop here I could go work for. I love building engines.

I can see where your coming from but the way I see it, the manufacturer makes conservative cars to cover large markets so sometimes there are potential gains sitting there waiting to tap into for the minority enthusiast by tuning tweaking etc. One example is oil catch cans which all cars should have as it improves performance as well as reducing expensive maintanence costs later, but the manufacturer knows no one will empty them and it also adds production costs eating into bottom line profits so they don't bother. These ECU tweaks might give better performance but might have traits that could put the average conservative purchaser off even ithough for us motor heads it is a bonus. I personally would be keen on a re map if I could organise one here in NZ.

[CraigB]

How is an oil catch can going to improve performance if you have oil blowing out of your breather hoses then you have serious engine issues...the only thing that should be blowing out of the hoses is vapour which is connected into the intake pipe forward enough that by the time it gets to the throttle body it is at normal air temperature anyway.

I've used catch cans in several of my race cars ( and my Mini ) and unless you're pumping out 9000rpm or more they're pointless, plus if they are correctly installed they self drain back into the engine and don't require emptying.

[omegaspeedy]

OK your right as I should have said maintain performance, unmeasurably you'll get the full benefit of the octane rating your using because the oily vapour coming through your PCV is being condensed in the can and not mixing with your fresh air. Maintaining performance long term by reducing the amount of carbonisation on your DRY inlet valves...yeah yeah its no a problem with Hyundai DI engines.....we'll see long term about that one 

I'm emptying two table spoons of oil (no water or other, just pure oil) every 1000Km out of mine. I drive hard everywhere. I personally think it's crazy not to have a catch can on these motors. That oil would have just collected either in the inlet manifold or deposited itself on valves pistons etc over time.

Heres my set up Hyundai i30, Elantra GT oil catch can. - YouTube

Sorry this is off topic.

[cruiserfied]

Off topic but still good talk. Maybe we need a Crap talk thread just for this talk.

[CraigB]

@Omegaspeedy, I don't know why you are getting that much oil come through... maybe the fact of driving it hard/thrashing it is what is causing it but still it would make no effect on your performance whatsoever.

Checking my breather hoses all the way down to throttle body and my system is dry, rather than worry about some 0.0001% of Hp you may lose  worry more about the damage you are doing to the engine and drive train with your driving style.

[omegaspeedy]

Craig, the oil I'm collecting in my catch can is in line with all other wise people who are running one. The PCV valve is connected to the rocker cover. It's just oily air that is vented from the crank case to the upper head gear this sucked out using manifold vacuum. I don't see why your surprised by the fact that oily air is being sucked through the PCV valve? It's coming from an oily environment, of course oily is present and the catch can condenses it as it should. I get the feeling that you think there is excessive gas bypass of the rings or something abnormal? I drive my car positively which I enjoy. I don't abuse it or red line it. How about you worry about the things you find important in your world and let me worry about the thing I think are important.  I'm not worried at all about HP loss from oily air. I just don't want F**Ked inlet valves 3 years down track.

[CraigB]

Personally I'm not worried, I just thought you might be...I mean if you're worried about breather vapour screwing up your valves ( which it wont ) I thought you'd be concerned with the damaged caused with excessive hard driving, not to worry as it's your choice

Back to the topic matter anyhow, if you've got ECU programing questions/answers then please continue...

Cars going in this Wednesday for the ECU tune the only difference is I'm going to use a different performance shop as the first one ( pace auto werks ) was feeding me a line of crap and his tunes aren't tailored specifically to my car, it would have been a generic tune for a Kia Rio 1.6 GDi engine and modifications to the ECU would have been very limited with Viezu.uk programming and thats if they could even do it correctly in the first place as apparently these ECU's cant be tuned through the OBD port.

The other shop ( RPW - Race Performance Works ) will remove the ECU from the car, open it up and connect to it directly and are able to much more tailoring, I'm also getting them to remove the main catalytic and swap it over for my high flow cat as they can also set/clear/block lambda codes which the first mob aren't able to do.

I should have stuck with RPW in the first place as I've used them before on some of my other cars but they were a little more expensive than Pace who mainly specialise in the European high performance vehicles like Lamborghini's - Ferrari's and such, now I know they're full of crap and those rich tosses with their Euro sports cars are getting done by shonky tuners
