V8 M3 Software Upgrade

[Devtri]

Starter Kit SK-I with 60KW / 125Nm is R80k ex warehouse

is that wkw and what is the price including delivery and fitting ?

 

[Rolf]

Thats engine kilowatts and ex warehouse doesn't include shipping (obviously) nor fitting!

G-Power starter Kits are designed for DIY and to get the best value for money!

The SK-III for example gives you +200KW / 300Nm and needs to be installed at a BMW dealership.... setback: R416.500,-

Rolf does G power keep MP intact if the install is done at bmw?

 

[dvst8]

Not everyone has the funds or want to SC their M3.

The guy asked for SW upgrades, how does SC, Crank upgrades etc come into the discussion.

SW on an M3 may see smaller gains compared to a turbo car on a dyno, however on the road the gains are noticed when you race against a stock SW M3.

Xcede have dome SW only on a number of M3's with realistic gains on the dyno as well as great on the road improvments.

A clear NO!

However G-Power warrant their products for 2 years

@dvst8
If you follow the thread you know how it came about crank and pistons and cams and and and.....

I did follow the thread dude, still dont see the relevance when the guy asked about a SW upgrade.

:idea:

 

[moranor@axis]

why does SK-III need to be installed at a BMW dealership then... to keep the warranty on the charger?

 

[Rolf]

1. The software part has been replied to..... by several people
2. All -except you- agree that software on that car doesn't make a big difference
3. No one doubts that Xcede do great software

Anything else you would like to add?

i think the 'SW upgrade' question was answered already so the discussion moved on...

The engine needs to be taken apart.
Its recommended not really compulsory; sorry if it came across the wrong way.

We here in Cape Town use SMG for our non DIY kits so its already in my mind to use BMW ...

Again sorry for expressing it the wrong way

I don't think it hurts to give out as much info as possible, this is a forum.

But sometimes a questions can really go off topic haha:rollsmile:

 

[Rolf]

agreed :ty:

lol well we still talking about the M3 so this tread is still looking good so far :rollsmile:

 

[dvst8]

Okay

All the okes who have done SW on their M3's wasted their time and money then.

Have seen SW only Xcede, Chiplogic and Motronic M3's run very strong on the strip as well as the road.

But hell, what do these tuners and owners know.

So I apologise, lets get back to the discussion on the only way to make an M3 faster is by throwing tons of money in SC, Cams etc.

:thumbs:

 

[Rolf]

Yeah.... same thing as a 316i owner who gets his software and is over the moon!

The relation is the same.... its all relative Einstein would say :bravo:

 

[moranor@axis]

i dont think SW only makes sense on any NA car you need to make other changes to increase airflow so you see a proper gain...

is it worth doing SW only? well i guess it depends on the person... for me if i mod a car i have to feel a good differance or its not worth it...

Supercharging in the way to go but that's that last resort. Unless you're looking to just splash out on 200k and say bye bye to MP.

Maybe sw shows minimal gains on NA cars but the V8 M3 does really wake up with sw, providing you have a decent catless exhaust. If you got a good tuner and exhaust look at around 40wkw gain.

Intakes are useless on the e9x M3, for the amount of money you spend can't can't be justified by the small gain in power. Cams coupled with a pulley upgrade is great but those schrick cams are pricey.

Well.... if you go THAT far then why not convert it to y 4998cc (new crank and pistons)?

cams and exhaust wont void MP?

what is the total cost for that 40kw?

Let me guess before he posts.... 120k ?

Well guys i've been chatting to Devtri for the past few days, seeing we have the same car, he has asked me for advise on mods, as i've done a few to mine.

I only commented here because you commented the low gains of a NA vehicle, and promoting a supercharger kit. That's like walking into a dealership to buy a Toyota corolla but the salesmen insisting that you purchase a Ferrari, makes no sense really.

I've got 40wkw at the coast with just stage 2 Xcede software and full exhaust, I won't divulge the price however its no where near 120K, actually a bargain when compared to a supercharger kit. I only mentioned cams because its the next step for the M3 if you still keeping in NA.

Not only cams or exhaust will cancel your MP any engine mod will, but the exhaust is easy to remove if the car has to go in for a service. Cams will cause a problem if there's a problem with the car and the heads need to be removed, however they aren't noticeable when fitted.

so did 40wkw make a huge difference on a 300kw car?

i have no doubt 40wkw will make a huge difference to the way a car feels on a car with less power but this is a 300kw car...

now 200kw on a 300kw car that you will definitely feel :rollsmile:

I hear what you saying about the cost but once you have the basic charger setup and have made that initial outlay making more power later is easy...

on an NA car the more power you make more the cost per kw goes up...

Im sure you have done some looking at the cost difference between going further with NA vs FI and if you were happy with the 40wkw im sure you would not be looking

the real question is did you 'waste' money on a tune if you still want more? does it make sense to save for an SC and start from there? this is why a supercharger was mentioned and is relevant to the discussion...

 

[dvst8]

But you always want more, thats just the nature of us.

Personally, i would start with a sw tune and work up from there unless you have the budget for a sc.

Not everyone is keen on the fi route on a M3.

Well the topic is M3 sw, so some did went off the topics with FI and SC...
