2005 330 coupe remapped

[ANT MAN]

Had my car remapped a few weeks ago by Simon Hall (www.e-maps.co.uk) and am very pleased with the results.

Low down torque is greatly improved and car pulls strongly from 1,500 rpm!

Mpg around town had improved though cruising at motorway speeds seems unchanged.

Mid-range is stronger and the engine races to the red line. I would describe the acceleration as relentless.

Throttle response / pickup is much improved too.

My ECU is the Siemens MS43 but had a revised code that Simon had never seen before. The code gets sent to Germany and a former BMW code writer performs the modifications and mails it back.

All in all took 3 hours approx and we went for a spin afterwards.
Simon came to my house and is a thoroughly good chap, very honest about the so called black art of remaps. I have a copy of my original map and revised one, as does Simon. He keeps a secure backup too.

I learnt alot about the business which was a real eye opener.

He also said mine was the nicest E46 he'd ever seen, bless :) ;)

Very good value for money mod. Car has now done 2050 miles and I will soon get it on the rollers as long as the DSC can be fully switched off.

[gringosteve]

Sounds interesting mate...where abouts are they based? Did it improve throttle response too?

DSC is fully switched off by holding the DSC button, rather than just pressing it. You should see the normal Yellow light come on, and eventually a yellow exclamation mark light will come on.. then your ready for the rollers..

[ANT MAN]

Aye, it did, pls see 5th line down.

I thought that the car still has the system in standby mode and when the rears are running on the rollers with the fronts still, the system cuts in at high revs?

I think Peppernick had the problem with his power run.

Ahh..hadnt heard of that problem mate.. sorry to confuse things [hmm

My old car had the SSG gearbox. Even with the DSC fully turned off, engine power cut out at exactly 6000RPM. Must be something to do with the gearbox software.

[Chaos]

Holding the button for 3 seconds will disable all traction and stability systems, despite what some people will tell you. The only exception is ABS which will remain on 100% of the time. I think Nick's right - his problem sounded like some sort of failsafe in the gearbox software and that would make perfect sense.

So will pressing the button on completion reinstate the DSC.

I'm going for further dyno session on Wednesday, not with AmD who did my remapp , because i'm adamant that my car is performing above what AmD's dyno plot states, I've had two other 330 drivers drive my car and they both say that my car really pulls strogner than theirs and revs a lot freely

So is the DSC always an issue when a BMW is put on the rollers ? any advice would be very welcome please.

Bob

[Chaos]

Yup just a simple press on the button after will turn it all back on. If you press the button and the light stays on, get it checked.

I wouldn't say the DSC is always an issue per se, just that you don't want anything interfering with your raw power output. Traction control isn't an issue on the dyno so get it off. There's about 5 or so different managed processes on the DSC system (aside from ABS) and you don't want any of them interfering so no need to have them on.

As an aside, I'm speaking to an old mechanic buddy later on tonight, so I'm gonna plug him for info on Nick's cut-out to see if he knows what it was and if it's engineered in for a reason.

[Lucky Bob]

Thanks Chaos

You've given me a glimmer of hope that my original AmD dyno plot may be wrong because of not isolating the DSC, Ant Man sorry for poaching your thread.

Simon did mine to about a week ago & I'm really pleased with the result. Simon is a true professional in a business that does it have rogues and I would recommend him to anyone who wants a remap !

Can simom set whatever rev limit he wants?

Im after a 7200rpm rev limit. I know its safe to take it to 7400rpm but just want a bit of failsafe.

[ian_79a]

do all bmw have DSC i have a 328i E46 on an S reg but cant seem to turn mine on :confused:

[peppernick]

Earlier E46s have ASC as opposed to DSC. So traction control without dynamic stability control (braking to individual wheels when car is struggling with traction).

He re-mamapped my 330 a few weeks ago. Dunno if he can raise the rev limit but i know he removes the top speed limiter.

[ANT MAN]

No problem Lucky Bob :) At least we've unravelled th DSC mystery.

Lee, I think the rev limit can be set to your preference. Like Nickleback's my speed limiter was removed but I kept the standard rev limit.

[Chaos]

Ian, wot Nick said ;). DSC has DBC (as Nick described) and the (hopefully) rarely-used MBC, which basically interprets a sudden stamp on the pedal as emergency braking and boosts brake force to the maximum tolerance of the ABS cut-off. (He said confidently, despite having the short-term memory of a goldfish. :p ). The button on the centre console should tell you which you have, ASC or DSC. ASC isn't bad, DSC is amazingly clever.

Anyway, I mentioned earlier that I'd speak to my mate tonight and he said he'd heard speak of a failsafe with E46s which shut the power off if the front wheels and the back wheels had a maximum difference of 6-6.5k rpm. He seemed to think it was linked to the DSC system and therefore this could be a prob. He's going to ask some of his contacts this week, but I don't think any of them are official Beemer guys so he may not get a 'factory' answer. I did read somewhere on E46fanatics yonks and yonks ago about someone managing one run at max revs after holding down the DSC button for between 8 and 10 seconds, no more no less, and it let them run to max rpm once and then wouldn't do it again that day - may be worth a go if you run into the same issue.

If I find anything more concrete out I'll holla.

Lee, with mine the top speed limiter has now been removed with the re-map. The file set now put on the car, means that mine (Auto box) now changes up @ 6500 rpm, 500 rpm further into the redline area instead of 6000 rpm as it was originally.
So I would guess that Simon's specialist out in Germany could set it up as you need it, so I would suggest that you give him a call to check?
Hope this helps?

[gringosteve]

Is 7400RPM safe for all 330i engines? Just wondering where this magic number comes from, and how many people have their limit raised to this value?

I spoke to Racing dynamics in the US, as ive bought a few secret bits off them for my next load of mods;). This is the limit they told me was safe.

[gringosteve]

Cool..like the idea of a 7000 RPM limit..at what point is max power developed in the engine though? If it is lower down the rev range then this wont have a massive effect on performnace on a standard engine..will just let you rev out of the power band further?

I need the extra rpm to help me though as my ratios, i barely hit 50mph in second now, plus im going even more with a 3.64 diff. Plus i have a supercharger to breath more air into there.:D

[gringosteve]

Ahh makes sense then mate... sounds like you can have a lot of fun when you add a supercharger to a 330.. :cool:

[jcross]

Mmmmmm. Very tempted by this. How much was it? Does anyone know if it's worth doing on older cars? Mine's a 330ci with 50k on the clock.

[gringosteve]

I have emailled the company to get some sample power curves and quotes. I'll post the response up here for everyone ;-)

Dude when it comes to modding, you're certifiable [bow [bow [bow

Performance headers and LSD? :D

[adood84]

but Lee has a Supercharger so his power output is not the same as the normal 330 so I would only assume that his max power output will be in a diffrent place on the power band?!!

[lee330sport]

Dude when it comes to modding, you're certifiable [bow [bow [bow

Performance headers and LSD? :D
Yep, next mods are performance headers with no Kats along with a one off re-map with a 7200rpm limit,new injectors and pulley. And ive already started to buy the parts for the E46 M3 rear end.

Thinking about an M3 dash now with the higher redline, dunno if its possible though, got some good info off MITE46.

The mirrors can wait.lol

[Raj]

Yep, Simon is a decent chap. And very good value for money.

My car went on G-Force Motorsport Dyno today and the results are a big improvement from when the re-mapp was carried out by AmD.

results 245bhp @ 5900rpm and a creditable 244 ft/Ibs @ 5900 rpm

I told the fellas at G-Force about the low before plot at AmD and they said that they can't remember the last time they plotted a stardard car and it produced the manufacturers figures, they are all low, with the exception of Porsche.

They had a BMW shoot out earlier this year, and they told me that most of the cars realised outputs lower than BMW state.

They also told me that they disable the DSC, and as someone posted earlier "press the DSC button" for more than 3 seconds and off it all comes including the ABS in my case.

They also told my that a lot of Jap cars have "smart" ECU's if you drive slowly over a long period of time they adapt for economy, if you rag it around they adapt for performance to a degree.

They were not 100% sure if this applied to BMW or not as they specialize in Porsche and Jap cars, but could not see any reason why not.

Went for a drive in their 350Z twin turbo which they bought from me eariler this year minus the turbo's , this car is now absolutley staggering 420bhp during the developement period and its going higher, TVR performance but it steers and stops, 4.6 second zero to sixty.

Ant-Man looking forward to the results of your dyno, if anyone is interested G-Force charge £55.00 + vat to go on their rolling road, and you can go in and watch.

If anyone is interested in re-mapps and wants to see my plots (steady ) I'll gladly e-mail them

Hi Mate..Nice gains!

Please can you email your plots and details of costs/locations for AMD remaps please to lomax30@hotmail.com.

pls mail your plots to anthony_shilson@hotmail.com

Also, I usually go to Power Engineering, Uxbridge for power runs.
Whereabouts are Gforce?

Btw, BMW's software works just like the Jap's you described above. The difference in throttle response is most notable when you put your foot down after poodling about. After the remap, this is much better and it's hard to notice any difference.
