My session w OBD-Tuning

hi all,

i took time 2 write tis brief write-up, mainly s 2 say tks to Dave Naidu (owner/tuner of OBD), to self-answer many queries abt tis tuning, and lastly, to feedback on e outcome.

pls note tat i m in no way related to OBD-Tuning, n no other commericial interst too. but jus 2 say w interested readers..........

i arrived at his place, 21 marsiling ind rd 9, at 1355hrs. saw dave coming out of his black GT3. we greeted n walked into his office. i told him, b4 anyting s 2 be started, i need a 10-min session of Q & A. wat impressed me was his convincing explaination of e way our ECU behaves; esp when i tot tat ours was in a way- self learning. yes, its self-learing based on our driving styles. but e nature of his product was: it s meant to improved (or extend to e most tolerrance levels )our factory-set parameters; obviously not meant to "over-do" e tuning n ultimately cause damaged to our engines. b4 dave could go deeper into e techinicalities, i stopped him n gladly asked him 2 proceed.

his handheld gadget was plugged into my OBD port, n it shows tat it needs 59mins to read...... thus displaying "reading......" during tis 59mins, we chatted abt tracking, handling set-ups, showing me his souped-up GT3, n of course showing me his office whiteboard tat since his biz started in june, there were alr 52 cars on his board. i was surprised tat BMWs stands 60% of his customers, other than e other continental makes like merc, fiat, audi, etc.... during tis time, i aso witness tat he got another appt to do-up a bimeer 630 tomolo at 2pm.

it was 1520hrs, n e handheld port was done! it was unplugged n i was on my way to work; nearby too.

at 1655hrs, i received a sms from dave: yr ecu s ready. i rushed there w much anxiety.... it took a mere 20mins to get e "improved" parameters loaded into my car. he started e engine, n stepped on 4 a few full revs (till almost redline at PARK position; which s unable w our stock ECU). more chats, paid up, shake hands, n goodbye.

jus turned out of his building, turn left turn right, even didnt leave tat industrial compund yet, i dialed his number...... cos i knew tis s wat i wanted, n didnt expect 2 get it jus like tat! i thank him again, n enjoyed my journey......

feedback: it really feels lighter to drive off, not butt feel! overtaking was indeed a breeze too. as everyone know tat at 1745hrs on SLE, it s a drive n slow-down situation........ it was much easier to drive, considering e fact tat i use tat rd twice a day. stopped at e lights at targore junction. once green, i floored off! n indeed, it was much more satisfying than few hrs ago.

i paid a slightly over $1000, plus i was advised tat in any case PML reset my ecu, i can always go back 2 get it re-read FOC.

dave s a nice man who not only explains well, but aso a hands-on professional.

do give tis product a consideration, n i (as a bimeer owner) assure u tat u ll feel different after e "cleverer" readings r loaded in.

cheers to Dave @ OBD-Tuning.8)

u may wanna reach him @ 8180-8008. :dance:
 
Re: My session w OBD-Tuning

interesting.
do you know what software he used?
And what parameters were altered?


btw. it's bimmer ;)

software, i dunno. but i can feel tat its good for me, when i drove off tis mrng to work. it certainly brightens up e drive alot. even crusing on e highway, i need not step so much like e previous days.

a few parameters dave mentioned r:
- air/fuel ratio; leaner a little bit,
- acceleration lag; which i do feel!
- rev/rpm limiter increased,
- gearing ratio......
e rest i didnt ask more alr.

jus tat e drive s really different, n car feels much lighter to drive:shakemyb:
 
Re: My session w OBD-Tuning

You should have done a before and after dyno to quantify the gains !!! Wasted......
 
Re: My session w OBD-Tuning

yes, a before/after dyno would have been useful.

BTW, a simple adjustment of the e-throttle would result in the sensation of a great gain in power, with little (if any), true gains on the dyno - like what the various throttle boosters offer.

glad you're enjoying your ride

that's right.
the description sounds like the feeling one gets from installing a sprint booster.
which is not a bad thing in itself.

but doesn't hurt to know what he's using.

Given Dave@OBD-Tuning has done that many cars, including Bimmers.
Perhaps he can share some his before/after results?
 
Re: My session w OBD-Tuning

I enquired before and found that our local OBD Tuning is an authorised agent of OBD Tuning in Optican in Germany, creators of the Optican flasher which is widely used.

Seems like BMS Tuning is another OBD agent who seems well known for tuning EVO's and WRX's.

Hopefully, this OBD tuning actually boosts engine output given the same rev levels and fuel consumption as before. Velocity & SB simply offer you power which you can already have by depressing the accelerator further.

Do you know if Dave re-mapped the parameters himself or was the data sent to OBD headquarters in Germany for re-mapping?

yup! he told me he sent to OBD headquarters in germany at 1600hrs sin time. then once he received, he texted me to return.

anyway, true tat it was wasted not to do a dyno before e remap, cos i really not free la. but i guess a dyno anytime now will be as useful n helpful. rite?

:roll:
 
Re: My session w OBD-Tuning

Wondering if they simply upload a generic map optimised for the stock version of each model.

Or does the remap take into account the unique parameters of each car, if it has mods installed such as an aftermarket intake and exhaust?

yup, thats the nail on the head question.

been holding back for that reason becos not sure if i want to "supersprint" my exhaust first.


Do update, if anyone has info. thanks

if i heard n understood correctly, it s "simply" to upload a generic map to optimise for each model.

when dave was starting out on my car, his handheld device shows READING....... 59mins later, after completed reading, my engine n chassics nos were displayed (not surprising).

dave enlighten me tat tis readings ll be sent to headquarters, n e ppl working there ll give a set of extended parameters; not streching e car's limits.

wat u guys r discussing abt, make sense. but being a NA car, upgrade of intakes & exos wouldn't make tat much difference to tat "new" set of parameters. jus like in e accord euro R, whether watever intake n exos we r using, a simple upgrade of Spoon or J's Racing ECU will be independant of each items. hope i explain well.

but if a particular car has got cams n valve-springs upgrade, then i would strongly recommend a fully self-adjustable ECU upgrade, thus tuning on e dyno.

in summary, i'd say for owners like me who ve dropped in a hurricane panel filter, n intending to upgrade e exos only, this OBD-thingy would be enuf 4 me. :woowooo:

frankly speaking, how much more can my 525 go? if power-crazy, i'd suggest a 335:laughlik:
 
Re: My session w OBD-Tuning

for my NA engine, i have checked around and the increase is probably 8% - 10% if lucky.

i think i'll pass.

How about Rob from DMS Automotive?

There is something i almost forget. On N52, due to valvetronic, it is very hard to push the red line further.
 
Re: My session w OBD-Tuning

If it's a generic map, it might work well with your car if it contains mostly stock components! It may actually have an adverse effect if you already switch it up with downpipes, exos, DCI etcetc. Like some feedback on the GIAC Stage 1 Flash, some people had problems when their car was too "Un-stock' like!

Just my 2c, flashes are great! But I guess it would be safer if it takes into account the parameters of the car rather than just a generic tune, kinda like a one size fit all.

most probably a generic map as the tuning couldnt have been done in 20 mins!

gearing ratio cannot be adjusted through a simple tune

jerr87;483400 said:

aiyah, not gearing ratio la. i must ve been wrong. dave said to me like if i m cruising, e original set up would be to change gears at (eg) 2200rpm, but due to fuel savings, it ll change at (eg) 2000rpm instead; smeting like tis.

paiseh i m not a technical person.

but one thing i gotta share here...............

since gotten my e60 for e past 6wks, i've been clocking 8 to 8.3km/l of petrol everytime e tank s empty when i reach e kiosk.

but yesterday when i reach his place, my petrol level was 1/4 used off, n e OBC reads 8.2km/l. after reloading e new software, having drove till jus slightly below e middle mark, it reads 9.1km/l. journey patterns r similar, as it was a normal work day/journey 4 me. i jus parked my car, n i still feel tat "lighter" throttle. :)

anyway, i gotta state tat i m in no way related to OBD-Tuning n its owner Dave. no commercial interest here too. i paid my sums, w receipt too. jus tat i tot tis upgrade would be nice to share here, esp for bimeer owners would jus wan light touches to their cars.

for my car, i ve changed e air filter, n now tis OBD-thingy. e last thing tat i m waiting for, s a nice pair of exos, like remus. obviously not forgetting tat i still got another mth to wait for my beloved rims. :thinking:

cheers to all!
