E46 330i tuning?

[eko]

Mate of mine has just picked up a 330 sport and is interested in throwing some money at it....exhaust,remap maybe?
Anyone offer any tips or links to whats good etc?

[blitz877]

get it mapped first then throw some money at it, there was a tunning guide a few issues back in pbmw, il see if iv got it at home

Surely if you wanna do the 'bolt-on-stuff' you would want the remap AFTER, so it takes advantage of the money throwing.

Get a performance manifold, big bore throttle body (or sort out the ITBs if they have them (not too sure with 330 engines)), open the airways if there is restriction (do they have MAFs?) with a better filter (the argument about filters will always go on), maybe a camshaft, new valves and springs, possibly vernier pully, if he wants to go that far and even port and polish the head. THEN the remap.

Simple is just performance mani and sort the air intake a bit, then remap. Nice sound, better throttle response and a bit more power.


Most cars have the same tuning options. N/A cars do the above, turbos/superc focus on parts can be a bit different.


I quite like the 330i M. Nearly bought one a few months back!

NayC, you obviously dont know what your on about, if you nearly bought one a few months back then you didnt look very close at what you were about to buy

Personally, I'd skip the remap - it'll do nothing for it in reality. You can reset the ECU on these and it will adapt to your driving style. A lot of people say the car is more responsive after a remap, when they'd of gotten the exact same result from doing the reset (you do it with the ignition)

Exhaust, and maybe a shielded induction kit would be as far as I'd go personally!

Adaptive ECU's are basically about throttle response, have no bearing on torque or power curves like a re-map does?

330 is a great car as is and the best mods I could think of would be suspension and best tyres he can afford.

a mate had both the diesel and petrol 330.iirc the remap gave him about 265bhp but the remapped diesel one gave a better race against my touring.

Perhaps he nearly bought one in his armchair.

superchargers are what really get them going! but not that cheap

Which is my exact point in saying people feel their car is more responsive?

The gains that most remapping companies proclaim on the newer N/A cars are generally pie in the sky.

Budget will probably be about a grand maximum.
Is resetting the ECU straightforward enough to do ie disconnecting the battery for a while?
Any suggestions on replacement exhaust make and filter?

[kdevitt]

For filter I'd go with the DaveF kit - its a shielded K&N filter, and has dyno proven gains. Exhaust wise, I'd usually recommend Eisenmann!

The adaptive values reset is very simple - can't remember it at the moment, but its just a matter of turning the ingiton on in a certain sequence from what I recall.

[stuartgallafant]

sell it and buy an M3!!

Most remapping companies are nothing more than cowboys with laptops, they know nothing about tuning and just flash somebody else's map onto your ECU!

Tony, these engines are hard work to mod properly, electronic throttle, tiny inlet/ex ports, EGR, air injection etc
Tell your friend to save his money and buy a proper engine. Without seriously redesigning this engine he will be lucky to see 10hp

And as for a dave F .....

[Simon13]

hence the s/charger comment!

[HMC]

Thats generic mapping which is not great, but someone good, such as sanspeed, who does a proper 'set up' will make real difference to the car. As for the induction kit and exhaust, not gonna do much good without re-mapping. If the budget is only £1k then just get a good nitrous setup.

There is a local company to me who do that. Dont have a clue about tuning. All they do is take about £350 off you, plug your car into their laptop, load a pre-designed map to the ecu and then rag it around the block to see if its worked

Air filter = has to be gruppe m! expensive but they look and sound the biz!

CA automotive have some tasty parts for e46's, might be worth showing him the link:

I think Simon is right - these look a lot more fun

Somewhat out of budget....

When I say I nearly bought one, there was two up for sale. And I've been in one before and they are nice cars. So I started looking and waiting round for some to pop up, but the ones that did pop up weren't even worth looking at.

So never seen their engines, so I persumed that they would follow general tuning options...

[Andyboy]

I wouldn't bother. As Dan says there's not much you can do. A remap might make it a bit more responsive, but it's worth banging one on a dyno and seeing if it does 230 bhp. Many don't thanks to shagged cam sensors, old plugs etc.
Spend the £350 remapping fee on some Tesco 99 octane fuel and some maintenance.

[DanThe]

Personally, id spend the money on a full valet and an AutoTrader ad

The design objectives for these engines were to reduce emissions while 'maintaining' power and MPG features of the engines predecessor which was the smaller capacity M52.
These engines were not designed to make power, if you strip one down its blatantly obvious

If you want more power get a different car

I'd spend it on a couple of prostitutes and a few lines.
