[Martin]

Friday saw us perform final tuning and then testing of the i30CRDi PCM upgrade. We have a couple of these cars now and have been performing testing in the pair of them to speed up the R&D process. As of today we are able to announce the i30 CRDi PCM upgrade available to the general public for $995

Bringing the boost on earlier with more aggressive VGT (Variable Nozzle Turbo) control gives a nice sharp ramp into torque. Overall boost pressure has been raised to 22psi up from the factory 19psi

To recap then, for i30 CRDi owners -
We offer the PCM upgrade (mail order) featured here for $995
We also have a rear muffler 'delete' pipe that sounds great for $100 (we didnt use this in our performance testing, however it does sound great)
Add $30 for overnight airfreight, and its a simple upgrade <img src="{SMILIES_PATH}/icon_e_smile.gif" alt="" title="Smile" />

The PCM is located on the side of the airbox and is held in position by four 10mm bolts -

hi Martin, have you got a comparison, between stock and your upgrade timed so i can see what gain in TQ & power is timed, to see how much quicker it comes on. thanks
John

[Martin]

The dyno controls the rate of the run, in this case allowing the car to accelerate at 10km/h per second
The timing of the run is therefore controlled and not 'free floating'

Actual acceleration timing is the key here (performed with an industry standard Racelogic Driftbox)
Stock
0-100km/h   9.6sec   0-400m 17.1
PCM Tune
0-100km/h   8.2sec   0-400m 15.7

Getting a good launch and limiting the wheelspin is the problem here

Hi Martin thats great work on the power up. Is there more tunning to come like exhaust and intake or is this as far as you will go. I was realy hoping you would get closer to the 130kw and 400nm that was aimed for?

Thanks jamie

[Martin]

Further power up will be via a turbocharger modification with a larger compressor wheel
More new on this later  

[Mick]

Hi Martin, Do you supply a replacement  PCM? Or is that a change-over price?

[Martin]

The reprogramming is performed to the vehicles original computer, which makes it an airbag job, and a day and half off the road

[Thumper]

Martin, I guess the ultimate question, can Hyundai detect the new maps in the ECU?

[Martin]

No they cant
They can only read the software version, the program header tag, and any fault codes.....no more, no less

[Thumper]

Sounds good.  

[Dazzler]

Hi Martin,

Great Work...Just a few questions from a non-mechanic.

0-100kph in 9.6 for a standard CRDi seems better than figures I've seen quoted on the net!

How do you reckon we would stand with our warranty if we have a gearbox or other drive train issue after fitting the Performance pack?

Are you looking at any braking upgrade or suspension tuning to handle the extra performance or is the SLX already up to the mark?

Guess we'll need to tell our insurance company too.....

There were others but I've gone blank  

Rgds,

Dazz

[Martin]

The only people that will ever know that the computer in the car has been remodified are a select few of which there are about 5 in Australia that have the necessary equipment. Of these 5 there is only 1 that I know of that could pick the changes to the software.....If you feel like informing your dealership and insurance company you have modified the computer thats your choice, and we wont advise you either way
Drivetrains have characteristically proven reliable in second gen onwards Hyundais so we dont expect to see any problems now

[Dazzler]

Thanks for your nice direct answers Martin.

Interesting about the tyres... The 15" Kuhmos on the SX have come in for criticism but most of us thought the 16" kumho/Hankook on the SLX were at least reasonable...

[Martin]

They probably are a reasonable tyre, just not grippy in any sense of the word, which makes for a bit of fun smoking that inside front laying onto the throttle out of tight 2nd gear corners

hi Martin, have you got a comparison, between stock and your upgrade timed so i can see what gain in TQ & power is timed, to see how much quicker it comes on. thanks
John

Hi martin, i still like it on load and time the run in second it takes to make the power and torque then compare, as there is no wind resistance or bumps on a dyno so can not really duplicate real word. so the timing before and after in seconds is how i like to see it not RPM as with RPM for all i know might have taken 15minutes to get to 1,000rpm , if you know what i mean m8.
but still good results.
cheers

Hi, i'm a bit of a noobie about all this mechanical car stuff but is this sort of like those ECU things we see on the net that increase the efficiency? ie those plug in boxes?

Reading part of what martin said "The reprogramming is performed to the vehicles original computer, which makes it an airbag job, and a day and half off the road"
it sounds like they send us a box that hooks up to the ECM and changes it without a need for keeping the box there? Also it requires a mechanic to update for you?

Sorry, just a bit confused

[Lakes]

Sounds good.  

Dazz, i thought i would give you my take.

It is hard to tell from just looking at the dyno graph, also it has 70KW then the next mark up does not have a # but i guess it's 80KW then it has written flywheel converted power is 100KW.( this is bull as no way in the world you can convert wheel power to flywheel power you need an engine dyno) so we have 80KW not 100KW but it's at the wheel. also it's very hard for me to compare with out driving the car. as i need a timed run to compare the two, but with a wheel driven dyno putting a load on the rollers then giving it a hard excelleration in 4th gear is hard on the motor so need it at the right rev, also would be a lot of friction tyre to roller, you also need a lot of air in the tyres to cut some friction. thats why i like the type dyno where you remove the wheel bolt the dyno to the hub, or with a bike you hook up the drive sproket to the dyno, then you give it full load and wide open throttle and time the runs, then compare how quick it made power and TQ stock & how quick it made power and TQ after the change.
just how i like to do it as it is a more accurate comparison

Then we come to the question of warranty, and will a hyundai dealer know if you have modified something, as Martin said only a few people he knows have the equipment to see what has been done. but if the change has made big gains that you can feel a lot, i'm thinking they test drive the cars when they service. they would feel its  a lot faster on the test drive. but who knows.
i have a friend that is freelance and very highly qualified . .insurance companies hire him when there is bad accidents with big claims or large diesel truck motors fail or blow up as they can cost a fortune. he goes in and finds out what went wrong, and he is very good at what he does mate. but as the i30 is a very cheap little car would not worry unless it hit an expensive car at high speed.
cheers

[Martin]

Sounds good.  

also it's very hard for me to compare with out driving the car. as i need a timed run to compare the two, but with a wheel driven dyno putting a load on the rollers then giving it a hard excelleration in 4th gear is hard on the motor so need it at the right rev, also would be a lot of friction tyre to roller, you also need a lot of air in the tyres to cut some friction. thats why i like the type dyno where you remove the wheel bolt the dyno to the hub, or with a bike you hook up the drive sproket to the dyno, then you give it full load and wide open throttle and time the runs, then compare how quick it made power and TQ stock & how quick it made power and TQ after the change.

I am not sure if you understand how a dyno works Lakes, but the constant reference to time based runs is a throwback to some of the old wives tales operators of the very cheap based inertia dynos used in the 70s and 80s. Rather than having proper electric retarders to brake the engines load, they were instead a big metal drum (roller) full of cement that weighed 5 tonne or so. How fast the vehicle could accelerate the drum was an indication of its power. Not particularly accurate, and no longer used by any professional developers. You should post some of the dyno results you have for your i30 Lakes outlining the way you like to perform the runs and then we will compare results

Sorry for the 'off topic' Martin, but the Kuhmos on my 18" rims are SH*T.

Back on topic - looks like you're getting good performance results with this upgrade. Hope the internals can take it - Has anyone looked inside the engine yet?

[Mick]

Hi Martin,

I am intrigued somewhat as to why you Guys are able to extract significantly more from the engine than Hyundai. I somehow doubt they have less resources or technical expertise.

Do Hyundai tune the engine conservatively to remove any reliability issues? Also I don't understand how the engine seems more efficient after your tune given that you report approx 4.5l/100km in your test drive.

I would of thought that more power would mean higher fuel use? Or is it that if driven to it's new capabilities it will consume more fuel than the factory tune?

[Martin]

You will more than likely find that Hyundai slowly upgrade the power of the engine via tuning over the life of the engine, releasing a 90kw version then maybe a 95kw version etc. Its the oldest trick in the book, tune the engine to the lowest common denominator, then slowly wind it up to keep market appeal

[Lakes]

the dyno i use is less than a year old.
i still stand by what i said about timing a run, just think about it m8.
Rev Per Minute, is how many revolutions per minute the motor turns, but that does not tell me how long it took the motor to get to 1,000 RPM does it. its always the last way you can ever get a salesman to demonstraight his product ( timed dyno run ) Amen.

[Martin]

The dyno you use may be a year old, but there are still plenty of cheap and cheerful entry level i.e. Dynojet units around that cannot control engine load as they are inertial type and not particularly accurate for tuning engines other than at wide open throttle making them good for a timed ramp, but very little else. A 'proper' chassis or engine dyno has a 'brake' which simulates a hill climb of variable 'steepness' with a 'ramp' set in km/h per sec at which the vehicle will be allowed to accelerate. The measure of power and torque is then indicated by the vehicles ability to pull against the strain gauge, or 'torque meter' in the dyno. The biggest benefit though is being able to hold the engine 'steady state' at given load versus rpm and then change the injector timing, fuel mass, and boost pressure to optimise engine torque and power, which can only be done with a retarder style dyno. This ability is common to Mainline, Bosch, Dyno Dynamics, top level Dynojet, Mustang Dyno and is the same principle and method that manufacturers use to rate and power/torque test their engines (they refer to this process as MBT or Mean Best Torque tuning).

The only correct measure of acceleration is GPS or vehicle based off the rollers, with there being very little real world relevance to how fast a vehicle can spin a cement drum mounted in a dyno frame. Many of the more switched on bike racers are ditching their cheapie inertia dynos and stepping up to top level setups that allow steady state tuning and reaping the benefits on both the road and the track. However I think we are going a little off track here. If would be good to see you post up some of the dyno testing you have performed on your i30 so we could get a feel for the type of equipment you use, and the methodology behind your testing...particularly interested in seeing the results of your exhaust

[Dazzler]

Hi Martin,

May I make a suggestion....

You have obviously gone to a lot of effort to tweak the i30 and no one doubts you have made a big gain. Do we have any members with standard i30 CRDi models located near your base?

I think it would be good if you could get a few of our members to test drive one of your upgraded vehicles and give us some feedback...

I am not in the market for such an upgrade but would like to see you benefit from your interaction with our club...

Cheers,

Darryl

[Milo]

Martin,

All I can say is well done.... I have been following your post over at LS1, and gotta say I'm pretty impressed....

I have "followed" your work way back when you started on Zoom, so i know what your on about.

I would get my I30 Flashed in a heartbeat...... IF I owned one...  Hopefully that will change in the near future.   8-)

Martin i'll post you a disc with two engines being dynoed on my friends Engine dyno, this style dyno you remove the motor and bolt it direct to the dyno. he runs new motors in on it then tunes then tests. the motors are sealed inside a room it's all measured with computers uses water to control load. i'll garrantee it ( the dyno ) will impress you, he has one of the best equipped machine shops i've seen but no one can find him ( that's how he likes it.
The Dyno i used for my bike is a New Superflow , i know what you mean about the old dynojets and so on, the only reason they uprated them to be more truthfull is superflow showed them up a few times. but american's like to brag as you know. just we here in australia like the truth.
thats a good dyno you have i checked it out i always call them Vane, my friend has one but it's a 10 year old Vane truck Dyno uses the same magnet load controler your model has, but this Unit was built to dyno Trucks and is real heavy duty. he bought it at an Auction was used by the TAFE  they have one like your's now. my friend is going to build one to his own design just use the Vane rollers and load control. sorry for posting like this.
 have you ever tuned a Supercharged V8 that use carb's? it's not easy!! but with EFI it's easier just takes more time maping fuel and ignition.
cheers

[Martin]

Lakes we have probably tuned over 50 high horsepower engine combinations on the engine dyno. Personally we use a Superflow SF-901 with 32 channel data logging. I am seriously considering getting a Mainline Engine Dyno - the best in the business - as Stone Brothers, HRT, and several other top line race teams use, very expensive though, starting to nudge $300,000 with the right control systems in place

While all this talk of dynos is fascinating and is probably of interest to a few here, it really isnt what this thread is about. I believe you have made a serious misjudgement Lakes if you thinking knowing someone that has an inertia dyno will arm you with enough information to discredit our 20 years of turbocharged petrol and diesel engine development. I form this opinion re your reference to 'calling bull' on our results. I certainly have more important ways to waste 20 minutes of a day countless other internet forums rather than banter with a guy that knows some guy with a dyno, add google, instant expert

 the guy who makes the mainline engine dyno worked for MoTeC, know him.
good dyno

[Thumper]

Martin, do you have a i30 available for a drive, so that prospective BUYERS may feel for themselves the tractive effort between their own i30 and a modded i30?

I have driven several 'Dyno Queens' that were pigs on the road, but had lovely graphs showing power. Others that I have driven on the track have shown mild improvements on graphs, but were a delight to drive on the track.

Proof is in the driveability.    (Which I have no doubt in, with regards to what you are supplying)

[Dazzler]

Hey Thumper.. Great minds think alike (I mentioned that a few posts ago in this thread but Martin seemed to miss it...
