ECU Remapping for M54

[neohkw]

Hi there,

Still a newbie here. Mind sharing with me how he will be doing the remapping? Dyno runs included?

Cheers!

En Feisal,
Count me in....15% increase on M54B30 wud be better than M54B25, if logic applies la. Easy choice for me :top:

15% = +35bhp wor can or not?

Feisal - can BVO supply remapped software on an eprom (OBD1) chip? Does it involve dyno time or is he just supplying a standard map? So if we have a non-stock engine how?

I am meeting up with Bernard from BVO Auto of Singapore (http://www.bvo-auto.com/) for ECU remapping this Saturday for my own car.

Bernard has asked if there is anyone else interested especially for M54 engines since he has a ready made mapping for it.

A club member recently did a remapping with him and now a happy bunny coz now he can overtake the express buses on NSE.

Here is a list of cars that uses the M54 - http://en.wikipedia.org/wiki/BMW_M54

If you are interested please list down your name and cars below:

0. Name / Car
1. feisaldzul / e39
2. shaifulo / m54b30
3. JohnJ- M54B25- E39- Japan Spec4.
5. pussy - kepoh only
6. funfer_fahrer M54B25 (note: only available after 10pm Saturday)
7.
8.
9. nazrie M54B25 (note: '9' is his favourite number. Don't ask me why?)

bro,
as far as i know he doesnt do that for OBD1.

if for non stock he will need to read your ECU and reprogram it.
so not for this trip. most probably u will need to go down to Singapore to do that.

 

[feisaldzul]

sorry I should have been clearer.

this is done in KL because Bernard will be here for the weekend on a business trip.

Maybe its just me, but I'm sceptical of claims for +35 bhp just from a remap. I'd like to see some before and after dynos.

I'm driving brudder and my 30 nt ready yet..heheh...what a waste..I really need a remap!!

 

[chairoger]

Bernard remapped mine 2 years ago. He will explain the entire process and do it in front of you, test the car and make the necessary adjustments before completing the job! I must say, he is the 'MAN'! :top:

Yup, very satisfied with his workshop, especially the skills of Ah Wee and David. Top notch professional and polite too.

Just to share.............I extracted the following from the Singapore BMW club's forum, comments from a Member on Bernard as follows,

Jan 2007
To put aside any doubts about how much are the actual gains, a before and after dyno on the M54 2.171 cc engine was done.

Factory specs:
a. 170 bhp at 6100rpm
b. 210Nm at 3500 rpm

Dyno before ecu flash:
a. 174 bhp at 6100 rpm (178 bhp at 6300 rpm)
b. 218 Nm at 3750rpm

(The car has some light mods, namely GruppeM, supersprint muffler, broquet and Volk Racing spark plugs. These may have pushed the power and torque marginally above factory specs.)

Dyno after ecu flash:
a. 194 bhp at 6100rpm (198 at 6300 rpm)
b. 242 Nm at 3900rpm

Both horsepower and torque register a gain of about 11%. Even the lowest torque of 222Nm (from 2250rpm onwards) is already above the pre-flash peak of 218Nm.
The figures now are on a par with the factory specs for M54 2.5l engine! I constantly check my rpm to see that the same power/torque is now realised at a lower rpm than before.
Bernard's background
He went to Italy for a 10 day intensive serial programming course.
Equipments that he bought back including OBDII flashing & Eprom read & write..... The only difference is Bernard will read the original map & re-write to each & individual preference/mods. Can fine tune the car till map is optimised & a near perfect AFR.
