15BHP Power Mod/Chip BMW

These mod chips being sold on ebay for £15-£30, do they really work?. I would like to get rid of the lag under 2000rpm on my 318 but something tells me these chips are rubbish. Any views?

Welcome  jasgrif11!! 

Like  Alex, i would say avoid those chips like the  plague!  The guys here had a remapping day earlier this year with some very good results. Anyone know if there is another remapping day in the pipeline? I could use getting the tds done!

Where in Limerick are you  based?

Cheers guys

My car is 2003 318i. What kind of price are we talking about for "Performance air filter with heat shield, exhaust and maybe a remap"? who has done this and what are the results like?

Denis I'm in Raheen. I would definately be interested in a remapping day.

And some E39 owners...

I wouldn't recommend anyone doing a remapping day - if you're getting it done you want to remapper to actually spend some time customising the map for your car, not just throw on the generic map for your car. I'm sure you can get a discount based on a number of guys getting it done at different times - I've had one or two places contact me about this since the remapping day disaster!

Also make sure you get a rolling road readout before its done - I'd recommend getting it done somewhere that has no connection to the person doing the remap. Then go back afterwards to the same place to check the results.

Is yours the 1.9 litre or 2.0 litre engine in the 318i? I've heard that e46's
don't respond too well to remaps. Dave F seems to do the best air filter with
heat shield and are custom made to fit each individual type of BMW. They're
about 160 pounds sterling but he'll give a discount to forum members. This
will give a couple of extra ponies but will make the engine a bit more
responsive. And of course it will sound a lot better. Diddo for a new exhaust.
I'd go for an Eisenmann one. Look HERE
Lots of guys here have these exhuasts but I've
only heard them on 6 cylinder cars so maybe get some opinions before
buying one for your car just to make sure.

As said DJ, Generic remaps arent really worth their weight, especially on a N/A car. I have heard nothing but good reports of martin treacy at westward and id also recommend martin at autoremap too. it would be best i think to phone up a few of the companies first and ask their honest opinion of e46 mapping and take it from there. Alex does make good points there on the induction/exhaust route, generally the most effective mods on N/A cars, but try talking to some of the mappers about the 2k flatspot you spoke about and take it from there would be my advice.

Yeah, I think I would like to do that. But where can you run DYNO around Dublin?

So, he's the same Martin Ben was talking about? Basicly, you're suggesting me get in there, run on DYNO, remap and run DYNO again? Well, we would get real HP gains than :) How much would remaping be?

I have an E30 with a 1.6 litre M40 engine. Not an ideal starting point I know but the car is a great little goer on the roads. Buddy of mine was telling me the best way to unleash some more ponies would be to get an aftermarket exhaust manifold....he said it is expensive but the best option if money ain't any object...that and a K&N filter. Does anybody agree/disagree with the above plan of action? And where can I source a decent aftermarket exhaust manifold?

Rgds, Colm

1993 E30 1.6 M40 Touring with 114k on the clock!

Ok valid points but an exhaust manifold is not going to give 20-30brake on a 1.6 e30 engine, or morst engines for that matter.

On a naturally aspirated engine like that your friend is right, promote airflow, and make it cold air, but you wont be seeing anything near 30 brake extra but it will breathe easier and feel more responsive. Im not sure how an M40 respnds to chipping but id imagine there wouldnt be a huge benefit,

The most bang for buck you will get though is by having a look in adverts here and buying eamos 325i conversion off him, as they say theres no replacement for cubic displacement.
