bmw ecu remapping

[jvhuiz]

hi guys,

anyone heard of ODB tuning? they are offering a promotion till 9th. OBD-Tuning.com.sg
a buddy of mine was asking and it sounds credible. approx. SG$1000 for 14bhp gain, 10% torque.
good or not?

Hi jv,

yes, i've heard of OBD but so far not sure if it is good.......hope to have some review from some owner that has done it...........

vroom vroom........

cheers

hi bro,
If they can allow test run said for 7 days full money refund then why not......must feel for yourself on your own car because as long as you are happy with the gain, you will feel that the money well spent.

I believe there are a few tuning too....like flash-in tuning, not sure what is the actual name....in Boss workshop at Sin Ming auto centre. I went there for my tuning as well

personal feelings.............

i was actually "supposed" to go for e 1st step of ECU retrieveal last wk. but due to work constraints, i was delayed.........

then went to PML for my first servicing...... bumped into my old-time personal frd at kg arang...... i mentioned to him abt tis OBDtuning thingy........ his reply was: he suspected tat e current (from 2006 onwards) 3 or 5 series ECU, r sort of "self-learing", jus in his n my case of accord Euro R ownership. in simpler terms, since 2003, honda has been launching their K-series engines. n it s a known fact tat e K-series use tat kindda "self-learing" ECU. some of e owners did upgraded to e infamous Hondata. but from my wkshop (we operate a claims wkshop) experiences, ALL those who uses Hondata, ll either ve their engines blown-up or incorrect tuning.

insummary, when these e Hondatas ECUs were removed, e owners were delighted w their car.

back to e PML service advisor (whom was my personal long time frd......he aso driving euro R now, i still ve my euro R too now...........) we more or less concluded tat my E60 ecu s more or less "self learning" too.......... his encounter w e other bimeers owners who did ecu tuning, was tat after some wks when they went back for dynostic tests, e ecu falls back to e original factory levels.

furthermore, last wk when i took my E60 to NSHW for a spin, when back in spore, my car felt more responisve n fuel consumption did improve a noticable lot.

****i m not trying to dampen any ecu-tuning biz here. but i would like to hear if any owners here share e same idea of "self-learning" ecu in our bimeers. for those who understand e term: "self-learing", then u would know wat i m talking abt.

wow wow.... the guru is here.....

i did spin n spin a few times in NSHW but fuel consumption didn't improve,,,,
perhaps mine not "self learning"?? perhaps you take mine to spin next round.... keke....

hmm, ...... ya ya ...... dun really understand snowdog's final sentence.......

i'm willing to try out dave naidu's ecu re-map. n ll be glad to post here. guess horsepower s by butt feel, but fuel consumption figures wont run away. anyway, for a thousand dollars, it's worth a try. i've alr checked w dave, shd PML re-program our car, dave ll gladly remap it foc.

tat s for remapping of ecu. but............... if MOTEC s willing to work w BMW or PML, then i ll purchase it for sure.

but, hopefully i ve time next week.............

gtg now, flying to penang in an hour's time. too tired to drive up.

enjoy e wkend, guys! have a nice mooncake

Re: bmw ecu remapping

pls share the result after your ecu re-map
have a nice trip to penang and enjoy

Re: bmw ecu remapping

One suggestion is to do 2 dyno tests - before and after - to ascertain the claimed gains. Same dyno machine, same temp/climate....... That way you know what worth on your $$$ you are spending for......

u r damn right, bro!

but i gotta find time first la. js got back from entertainment, wash up, now jus rushing thru e forum........ then gotta knooz liao........ tomolo first thing awake, gotta take my euro R to go PG, got mini track day..... got some hunting to do there...........:sneaky:

of course i ll post it here, if e remapping results r positive.

hmmm.............. tomolo after back from PG, got another dinner...........

wednesday gotta bring wifey see fishes.......... maybe ll see till thursday then make final purchase...........

friday a long day for me, from dawn to midnite...............

saturday, e usual accord-day at my wkshop......... catch up w old kakis........... then family time liao............

Re: bmw ecu remapping

the ECU is "self-learning" for sure. I went on buz trip and left car with brother-in-law for a week, whose driving style is a lot more robust, shall we say, than mine. when i got back the car response was so different i thot he did something to the ecu...a week later the car was back to my more *sedate* driving style....

 

[spinworks]

I had my 525 ECU remapped recently!

Hi guys
I have my brand new 525 remapped a week ago and I can tell you it's worth it! My torque improved approximately 30%, my rev is delimit i.e. I dont have to floor my car to hit 4000 or more rpm. Frankly it does not go back to the original stock ecu. I think once you get use to the new speed you want more and more and more!

So I say go for it!

Cheers spinworks

Re: bmw ecu remapping

Let me share a little of my experience with OBDtuning. I've approached Dave couple of month ago for his ECU remapping on my 323i. He is a very nice guy and patiently explained what kind of improvements that I will experience after tuning. As he mentioned, he will, first, download the current ECU map and send it to Germany for the techs to twig for improvement, then re-install with the new ECU.

After he installed the re-mapped ECU and when for a test drive, together, felt a little improvement on the torque (butt feel), but not much. As I complained about not much improvement, he mentioned that I will feel further improvement, as I drive more, and the full gain of the re-mapped ability will be truly felted after 3 tanks of gas refill.

As he offered 7 days money back if no improvement is being felt, I tested out the car in various driving style and conditions during these 7 days. However, the feeling is about the same as initial test drive, even after 5~6 days (not much improvement). With this, I requested for money back, which he kept his promise. As my car was the initial 323i that he re-mapped, he offered me to keep the ECU re-mapped program.

I've been driving with the tuned ECU for around 3 months+ (a lot more than 3 tanks of gas re-fill), and I confirmed that the gain is not much (by butt feel).

One more note. As Dave mentioned, the fuel efficiency will improve during normal driving, because the gears will shift smoother at lower rpm. Again, I do not witness this phenomenon, and my fuel efficiency got worst than before (with no change in driving style). At first, I thought possibly that my service time is getting close and I need to change my engine oil. However, after servicing, my fuel efficiency still maintains in the worst state. (I even change the oil usage from PML's standard Castro to Mobile 1.)

Of course, different people has different experiences, as Dave has previously mentioned that he has tuned 523i, and his customer was extremely happy with the improvement. Sorry to say that such improvement is not being felt on my 323i.

Re: bmw ecu remapping

had my 523 reflashed by dave about a month ago.
great job, feel slightly more power and the engine sound more solid.
my detuned N52B25 used to drag itself from 4k rpm to redline and now it is much sweeter at this range too

just like what dave says, it free up the engine to its true potential

however, my fuel consumption goes up a notch to about 12L/100km...... from 11L/100km
the reason is i tend to rev it up whenever possible to feel the power. Shioook !!!!
i suppose under the same driving pattern, FC should remain the same

highly recommended mod ...... Cheers

Hi jonsuta,

have you tried loading back your original program?
perhaps it could be due to some other cause other that his new mapping..
if FC is worsening, i suppose you should load back your original setting to try and remedy this situation

Re: bmw ecu remapping

personally, i had been driving jap sportscar and have always been into modding. I am always surprised by ppl say who say they could pull gains as high as 60bhp simply by remapping the ecu. i don believe that cud happen to jap sportscar. maybe they are a diff breed...still im skeptical about ppl experience of high gains purely on ecu remapping. to remap ecu without other modifications shld yield small gains from 5-15bhp, anything higher, other mods have to come in. thats my exp from jap sportscar tho....i tink the theory of power gains always fall back on the old saying.....more power always means that yr car needs to breathe more and drink more. im still new to bimmer engines tho....so feel free to correct me

cheers =)
