Remap e46 330i

I had Simon at e-maps do mine, think the cost at the time ( 3 years ago ) was about £300 or there abouts.

I noticed the mpg on mine increase from around 19mpg urban to about 22 - 23.

Why would it need to wait until the car was being serviced, very confusing. I didnt wait for a service or an MOT :confused:

It isn't even that expensive, £50 for the kit and then 6-7 hours labour.

you get confused quite a lot :p 6-7 hours of labour is a lot of money to fix something I show no symptoms of possessing, fair enough it will need doing at some stage but it will have to wait until funds allow, I have other priorities atm.

And any noticeable difference in power delivery etc or was it only better mpg?

I'm not sure why I started this thread tbh, as I say funds are restricting me atm but I thought OcUK motors would be 100% in agreement that a remap is definitely worth doing and if this was the case then maybe I would have skimped on food or something for a month but, as it goes, there are mixed opinions which mostly favour the 'not really worth it' camp - my wife is doing a solo of the 'dance of joy'

Not at all. 300ish quid labour at an indy, similar to the money you would spend on a remap.

Not sure why you think I get 'confused'?

He aint going to find a 50 quid an hour indie in Sutton :)
 
I'm only guessing at how long it would take an indy, a competent guy would do it in less time. Cant see it costing more than that.

Worth doing the research into at the very least. As far as 330i costs go its not one of the biggest you'll face.

True, i would get it mechanically perfect before i started tuning it.
 
My thoughts exactly. It's a normally aspirated engine as well so big gains will never be had from remaps. Or I'd have done it myself already.

If you want more power, BMW added two turbos to this engine, called it an N54, gave it 306bhp and thats where you should go ;)
 
I had my 320i remapped, and I've recently had my 330i remapped also. Both by Simon at e-maps.

I wouldn't say I've noticed any power gains, but it is smoother, seems to have more guts low down and throttle is sharper, but not silly sharp like with a sprint booster (yuk). I'm also getting a fair few miles more out of a full tank.

Interesting to hear about vanos seals. Might have to look at that.

Would I do it again, yes.
 
Mostly Placebo I would have thought. I just dont buy the all the benefits with no downsides thing of these maps - better driveability, more response and better economy? BMW UK would have insisted on this sort of map as standard if that truely was the case.

Remember the 330i DID come in a higher power variant in the US market - 240bhp - and it required engine modifications to make this!
 
They (BMW/Porsche/whoever)blame not having optimised maps on different grades of fuel and servicing in different markets.

They blame that for having a "jack of all trades, master of none map"
 
But they can and do release vehicles and ECU maps for specific markets.

There is no EU 330i Sport, for example - only we get it.

On a turbocharged car I completely understand remapping. More power, potentially lower turbo life, more fuel used. It's a balance, and you make a choice to go for power over economy which is something they chose not to.

But people claim for N/A cars its ALL good with NO downside?

Iv only had one NA car mapped (in fact only one car) that was a 3 year old (at the time) e32 735 all it did for me was get rid of a tiny hesitation those cars all had. No performance benefit, no improved MPG.

I suppose things might have moved on since then, but i wouldnt hold my breath, thats why i would go with Superchips if i was going to, as they have a 7 day refund policy.

You had a car remapped in like 1993? You must have been an early pioneer :p

It was a silver J reg, i had it done in Essex, he who dares wins i tell you!

With black leather it was a fab car, with the cross spoke alloys :)
 
The way I'd look at doing things is changing Vanos, cooling system, exhaust and air intake to get the most out of the car in it's current configuration.

Then, at a later date look at the remap option to increase the performance and/or economy gains seen from these mods.

I don't expect you'd see massive gains as you would expect from a turbo'd car but anything to aid the driving experience without causing reliability to suffer significantly would be a benefit in my eyes. (Albeit with a much larger cost to performance ratio unfortunately...!)

For more pronounced power gains I think you'd have to go FI and reading around, supercharging or turbocharging these engines requires significant internal work to maintain a level of reliability for a daily driver, high annual mileage car.

If I was to go down any modification route on mine, I'd go down the tuning it in NA form to get the most out of it, but that's mainly as I use the car a lot.

Just my 2c.
 
In the early days of the E46 M3 a number of people I knew got their cars 'mapped' and most came back speaking like it was the 2nd coming, effusing about how amazing it made the car, how much quicker it was and how it felt like another 20-30bhp. I remained dubious and actually had some side by sides with a couple of people I knew with mapped cars, both times my M3 (standard) being quicker. I ask most of those people today and there answer is the same. Waste of time....looking back. Lots of people 'want' to believe but reality is with such a car it's going to do pretty much the lump sum of sod all.

Absolutely no need to change cooling system before you have to.

More as a precautionary for peace of mind other than anything else. I realise its not necessary but its something I'd want to do to mine anyway especially as the mileage crept up.
