As some of you may know, I've been contemplating an ECU upgrade for about a month now. I'm taking my car from 169KW/320nm to 190KW/410nm.

I've asked what is changed on the car, and received this reply :

We modify 4-6 paramaters in the ECM in the car:
The most important one's are :boost.fuel,Timing,Throttle response :
The boost will go up to around 1.2 BAR - Just remember that its a low pressure turbo so this figure is not too much.
We then do timing - advance per gear and the fueling is also increased
We adjust the pedal sensitivity to ensure the car responds allot faster.

Nothing - aside from boost - look too risky? Currently the car runs at .8 bar
 
Not sure if anyone has mentioned this before, but why not consider a piggyback chip instead? If you want to go back to stock (selling the car, services) its almost as simple as unplugging the extra ECU
 
It takes 5 minutes to put the car back to stock through the OBD port. He'll do it at no charge for me when I go for services. Alternativly, I can buy a cable myself through him and change whenever I want.

Ok, that works too :D I say go for it...

What car is it BTW?
 
Volvo C30 T5

I've just been concerned with reliabilty, but browsing the sites, it seems alright actually
 
what about a wather meth kit as well, just to be safe.

Yeah, the change from 0.8 to 1.2 isn't that much. I have a Nissan S14 200SX and pushed that to 1.5 from 0.8 and no problems, other than fuel consumption ;)
 
Oh! I see what it is ...

I have an upgraded intercooler. Does a similar job?
 
Water Meth kit reduces air intake temps...so you can boost higher...

You say low pressure turbo???What does that mean?

Remember Dolby, many performance cars are set from factory to be either extremely reliable than very fast...so the reason for the sudden spike in chip tuning is becuase tuners know this...cars are underperforming naturally.

But if a Ford ST can handle 250kw DAILY then no probs why yours can't go 190...go for it, may I ask who will do the tuning and the price?

I think the car's sound will also change to that adictive fart sound...I bet you'll change the exhaust come 2cnd or 3rd quarter of this year...powa is addictive mate!
 
From what i've seen in upping the boost in cars, theres two sides.

Firstly all the components, are the conrods strong enough, are the pistons up for the job, can the bearings handle the extra etc etc. Now with a small increase in boost you probably are still good with stock standard parts but its really car dependant.

Secondly is the control , basically you need the right amount of fuel, the right air, the right timing and the right tempreatures. So if the boost is upped, there needs to be more fuel. Will the stock intercooler be able to keep this new flow of air cool enough. Will the turbos cooler be able to cool the oil enough etc etc. This is where it generally goes wrong. People have engines that can handle the extra power, so they up the boost, not enough fuel and it runs lean and end of story. Or the turbo dies cause it gets too hot, or it dies cause the wastegate cannot expel the extra boosted air, etc etc.

You just need one of the components not being able to cope to just about destroy everything else.

Now on your car they are upping the boost and adjusting the fuel, so what is gonna take strain, well your intercooler will be trying to cool more air, you turbo is going to be getting hotter, can its oil cooler cope? The stock ecu would of had knock/detonation protection , with modifying the maps will the parameters of these safe maps still be in the "safe zone"?

Same function as an intercooler?

Nope - want nothing physical changed on the car. Prefer it straight from the factory.
 
Oh - I'm doing it through Elevate cars (formerly Evolve). They're the largest Volvo tuning company in the world. He's charging me a good price of R5,500.00 for the software.

He's the previous owner of my car and he's the MD of Elevate South Africa though.
 
BBoy...agree with what you say BUT...depends on where Dolby gets the car done, most chip tuners know the parameters of safe powah...

Dolby, no...intercooler does that same job but water meth is added for extra cool...waybe you can think of it like a premature NO2...but without the kick...

Do the chip dude and don't look back - first on your hitlist...standard Audi S3?

Fair enough - that's why it's taken me so long to decide.

The power increase is not even 15% though and they all say I can run that on the standard intercooler, but I've already got a double capacity intercooler incase.

Apparantly the T5 engine is quite strong and as pointed out, there are quite a few STs with the near 200KW driving around. I've googled around and 190KW seems safe.

Latly, it is a global Volvo specialist tuner so I assume he knows what he's doing.

However - you brought up every concern I had
 
Elevate SA...great then, no worries, obviously he knows his Valva's from his Audi's...shot man go get it!
 
Some ST's push close to 300kw on wheels bra...aided wiff NO2 and obviously every other conceivable mod...

Nah - an S3 would still take me.

I'd guess with the conversion, late 6's and a just under 15 sec 1/4 mile.
 
Didn't Evolve have that light blueish T5 in Speed and Sound a couple of years ago? I'm sure they did...

You can't go wrong with Marquee specialist tuners!
