xr2i-carl

as im sure some of you may remember back in june my fathers 535d was stolen in coventry, its since been recovered but was in bits along with 4 other bmw's

he has been paid out etc and has just put a deposit down on a new 335i

does anyone know of any companies who tune this 3.0 twin turbo engine and what sort of fugures there acheiving?

will this affect the bmw warranty and/or do bmw offer an upgrade on the power

as standard they are 305bhp!!


any help mucho appreciated

Not sure but give DMS a shout as they are aboutt he best and give you a warrenty thats why they are a bit ont he pricy side.

xr2i-carl

You need to speak to thorney motorsport, they are the daddies of the BMW tuning world.

They have one on prototype right now, and are setting up a chip and tune for it.

That said, they dynoed the engine at quite a lot more than BMW claim as standard!!!!!

One word on the warranty - if BMW can tell it has been tuned, guaranteed it will void the warranty.

Drive it first, they aint slow as they come!!

you play with the engine, and most of your warrant is gone.

Hang on....he went from a 525d..... to a 335i. (top choice btw)

so hes gone from a real proper oil burner to a cutting edge twin turbo machine (arguably the first turbo car bm have made for the road) and he wants to tune it.....

errr, try driving all 306hp of it and then think about tuning it. I Wouldnt mess around with it until A, the warranty runs out or B, 306hp with no turbo lag gets boring....

There was an article recently on this.

I don't think anywhere in UK has come up with a guaranteed power output yet as they are still working on developing it.

Birds UK say they will probably do 2 conversions
One a remap for about 340bhp
The other replacing turbos ( originals are quite small ) etc to give maybe 380bhp.
I think DMS, CA Automotive, Ray West etc all said much the same - still under development.

Chipped UK ( Trubador?) reckon they can get about 360bhp-ish with a remap.

xr2i-carl

he is going from a 535d not 525, there pants!!!!


yeah its just an option, to tune the car up, why not???? surely like rhys said some companies may offer a warranty!!!

carl

xr2i-carl

the 535d is cutting engine technology aswell twin sequential turbos on a DENSEL

was fookin ace, looked the bollox too, she was was stolen sadly

it aint a big jump for him, he has had fater cars anyhow

Stavros

Writeup on this in latest Total BMW, fair few tuners already saying they can get 40bhp/60lbft out of it with just a remap IIRC, and its supposedly undetecable so not fucking the warrenty.

One company has an exhaust too, which will no doubt help loads if its turbo back.

Mike1

I think that was Ray West wasn't it?

JjCoDeX75

The only slight prob with these "undetectable" tuning jobs, is that normally the ECU leaves an imprint of the date it was last flashed. They can then compare with their records and check.

This is only an issue of course if the engine melts etc.

I have a BMW warranty, and it is very very very good. Frankly for a poxy 40bhp I would not even consider risking it!

Why bother - you would still be slower than a well sorted M3, and still quicker than an old M3.

As Silver999 says, drive it first. I have driven one, and they aint lacking for speed.

JJ

Mike1

As above I must admit I had a go in one and was impressed with the engine, exhaust note.

Personally I'd be more interested in seeing if they did a Sport suspension pack and LSD in the aftermarket - i don't think BM will offer a LSD as it will detract from the M3 which i guess will have these on.

AlexF

The ECUs can only be flashed a certain number of times before you need to buy a new one...

the DME (as its called in BMW speak) also records peak boost and any warning lights it has shown the customer....

Thats usually enough to find the modifications... and thats only the stuff the dealer can see....

BMW can see MUCH MUCH more...

Alex

xr2i-carl

some people have said they are making more power than bmw quote and if there still they same as they used to as quoting a slower0-60 than what they really are should be as quick as an m3 maybe

JjCoDeX75

They aint far off it mate. I have seen this with my own eyes!!

JJ

xr2i-carl

well they quote 10.2 0-60 for my 318is coupe, i have done 16.6 1/4mile and i know i could have got a low 16 if not a 16 dead if at the time i had known how to turn off traction control because it realy was bogging down!! (was first weekend i owned it and iddnt know you could turn it off )

now that 1/4m time would indicate a lot quicker 0-60 than 10.2 more like 8.2-8.5

also the e36 3.0 m3 book figure was something like 6 sec dead

i know of many of thesewhich have got times of 13.5, how many 6 sec 0-60 cars get a 1/4m time that good....?


escort cossie book figure is what 5.7 and they 1/4 in roughly give or take a few tenths 14.5

JjCoDeX75

What I meant was that the pace of the 335i is not far off the pace of the M3. not sure if that was clear

JJ

xr2i-carl

oh right mate, yeah i rekon they will be quicker than e36 m3 evo and prob as quick as an e36 m3

i will let you know once he has got it and let me out for a spin

Mike1

I had an invitation test drive in one about a month or so back ( only because we have had 2 BM 3-series and a Cooper S from the local dealer ) and personally I think the 335i is a different character to an M3.
Whenever i've been out in an M3 they seem to do all their best work at the top end of the revs and they're a "harder" character than the normal 3-series.
The 335i I drove had lots of low end poke and was fairly effortless to wind it up to big speed - however, it seemed fairly soft suspension wise to me.
I'm sure you'd give an M3 a hard time in a straight line and he'd be really having to work his engine/gearbox out of slower corners. Think the M-cars would show their worth in the bends though.
I know the US mags got faster times than Autocar for the 335i though....but they always seem to so I'm not sure if they test the same.

If you're interested, here are the Autocar test times with real timing gear

With a good suspension kit, maybe an aftermarket LSD & with 30 or 40 extra bhp, I think they'll make a fun car in 5 or 6 years time for not too much cash

xr2i-carl

not alot in it then also being turbo easy bhp gains


what abiut e46?

Mike1

E46s tested a bit quicker - think it's the handling that marks out the M-cars though - esp in extremis

xr2i-carl

yes mate deffo

Rhys

1.5 tonnes for M3 am i reading that correct?

Mike1

Yes, I typed it correctly - about 1250->1300kg for a Sapphire if I remember correctly.

Rhys

Wow thats heavy. Hmmm i wonder what my derv is will have to look into that

Mike1

Probably about the same Rhys ( around 1500kg ). Just think of all the extra stuff it has got on it compared to a Sapphire. Climate Control, extra sound deadening etc etc

Mike1

Rhys

Just looked and according to the 184bhp version tested by Autocar 3/5/2000 it weighed 1520kg

Rhys

Proper fat boy lol

There are many myth`s about tuning bmw engines.
This car runs off an edc16 dme controller.

HW number: 0281011762
SW number: 1037372066
Eprom: M58BW016DB PQFP80
Flash 3_V 512 x 32
8 bit chksum: 1E86 Inv
16 bit chksum: 3298

You can write to this ecu as many times as you like and as it is done via the BDM pads there are no counters and no date stamps.
You can modify this controller without bmw being able to tell, in fact if the checksum were to be different the car wouldnt start as this needs to be EXACTLY the same as original.

You can modify many features on this ecu including.

Boost Pressure
Boost Limiter
Injection at Part Load
RPM Indicator
Torque Limiter
VMAX
Airflow
Overboost

Some of these selections have multiple maps but its a relatively easy ecu to modify if you know what works.

40-60hp is not a problem on the stock engine and wont cause you any troubles.

Ive done several now, all with fantastic results.

AlexF

you've done several?

really?

several 335i s?


Alex

AlexF

for an answer

Chipped UK LTD

I tried to post earlier.

When i read the post i read it as 535d then i but answered as 535d.

Of course for the gasoline it will differ but at the same time be similar in that you can alter many paths and gains will be around the 50hp on mild tune levels.

RichardPON

Jayson - you have no idea what Alex does for a living do you?

Chipped UK LTD

Yes i do but thats not the point.
What i have said is 100% correct.

AlexF

I have seen the software TODAY that BMW themselves use.

You can look at so so much it very cool.

Many faults don't even display on the dealer system show up on there

We checked a couple of "clean" vehicles just for the hell of it.

Alex

AlexF

I'm not snipping before anyone gets that idea... I'm intrested in what the aftermarket can do

Chipped UK LTD

The dealer systems have been notoriously limited since a while back now due to dealers doing work without royalties being paid too the manufacturer.

Even our autologic tells us more than some dealer equipment can show.

What system do you use to read ?
