Re: Re-Program ECU Flash for E90 320i
very interesting thread..spoken to him yesterday, he says it will have a 10-15 increase in hp.
yes...i second louis....a dyno will be a much more accurate gauge.
smoobies, u did the dyno, how is it? what is the hp gain after the reflash? ...shed some light can....thks

NCP and all bros who have completed the upgrade - mind if I ask about the impact on your fuel consumption? With a 10% increase in BHP, does that mean you burn 10% more fuel. I am keen and will be visiting BVO in the next few days.

Based on my limited beng knowledge, it is to fine tune the air-fuel ratio to achieve lean burn for better power n FC n throttle response. Stock is always on the rich side.

NCP - thanks. From your own experience, is this ECU upgrade a die die must try mod? Any regrets? I will visit BVO in the coming days for a quote and more answers. Many thanks in advance for sharing.
AhBengDriver - you are certainly the most intelligent Beng I know. Always fun reading your posts.

There is certainly no such thing as a die die must try mod. Its all depend on how much you are willing to spend to enhance your car driving pleasure. But end of the day, we are still a 320i and won't expect to outrun a 323 but for 520, we may have a chance....with the upgrade.

Re: Re-Program ECU Flash for E90 320i
I corresponded with someone at e46fanatics.com about this matter specifically.
He told me that under WOT and normal driving, the car runs different maps. What the ECU adaptation does is under normal driving conditions, it will adapt the fueling and ignition timing to make the AFR as close to the normal 14.7 or thereabouts as possible Under WOT, the car switches to a different map to ensure there is enough fuel to make safe power (AFR below 12).
So when your car is tuned for power, it won't revert back to stock unless the tuner did something wrong uploading the map.
I'm but a layman and don't know anything technical. Just repeating what he said...

Re: Re-Program ECU Flash for E90 320i
i did it last couple of weeks back..
had the base dyno and after also..
gain 14bhp, and 20nm of torque!!! (be4 final last tuning, figures might be higher)
(mod include GruppeM intake, Bastuck exhaust, Sprint + Coil booster + IVAC )
your butt for sure can feel it..

He was referring to my engine. Dunno what fancy number that is. I only know it as M54.

Re: Re-Program ECU Flash for E90 320i
Hi Bro,
I did mine ecu reflash with BVO bernard for my E90 320. The ride was much more drivable torque did increase and i had slightly better horse power increased. Overall the whole car was much more responsive in performance. I just upgraded to a E90 325 last month my ECU was also just tune up last week by BVO bernard. Tink its worth spending the cash cause there isnt much upgrade we can do for our car performance, unless you want to get the supercharger kit for E90 320 4cyclinder. ARMA RACING
