I own a 2006 xB And Im wondering if there is an ECU upgrade, or maybe a ECU reflash available at my local dealership that I can get? Also Does anyone recomend an aftermarket performance ECU?

I personally don't know of any aftermarket ones, I'm sure its possible but for sure the dealerships do not offer an upgrade ecu reflash.

you may have a bit of luck with a piggy back air/fuel controller. you can create a new fuel map through the full rpm range, based on a dyno test or in conjunction with a wideband sensor.

i'm running a jdm bb ecu on my 06.....car runs sweet..only thing is that u realy have to let it warmup first thing in the morning before the vvt-i kicks in and u have to run super unleaded if not it pings....

Thanks.....
*Where did you get the JDM BB ECU? Costs, Ect?
Is the ECU Sotware avail anywheres? Ive got a tuner who will do the flash if I can get the software!!!

i got it from a friend that is staioned in japan in the army..he got it for me and someother jdm parts when he came home for x-mas...

what differences have you noticed with the bb ecu?
Gains / losses... everything works properly, your clock is in japanese kanji now, things like that... more power? can you elaborate on "car Runs Sweet now"? i am interested in changing the ecu myself... for a while i was looking toi get an echo ecu which does not have vvt-i so i could really maximise a new fuel map, but the bb ecu may be a better option as only the fuel maps are set differently then ours, but to my knowlage everything else is the same or very close...

well performance wise is alot better....more top end, bottom end torques is good up untill the vvi-t kicks in around 4500rpm and then it pull hardered to about 8 grand..that when the rev limter kicks in...but the down side is u have to run super unleaded gas cause it pings under load if u dont use it..also to when siting over night and starting up it runs rough till it comes out of open loop to closed loop..reason being is it only use one of the 02 sensor instead of 2 like the stock ecu...and the gas millage went down a bit..but it's worth it especailly pulling away from other xb's on the road...

IH8ONYU

thats what i was expecting, thanks for the info!

SLIM187

no problem...and good thing about it is that u can run it with out a cat. convertor..but when u put the stock ecu back in..u have to run the cat. convertor due to the secondary o2 sensor....

That also explains why the bB gets a wider sparkplug gap of .044 instead of .032.

now i just need to make a friend in japan...

there are ECU upgrades available for the our cars. Well for the 1-nzfe that is. Its made for the yaris and I can't figure out the c-one page. Here is the link http://ssmotorsport-bg.com/en/produc...ta%20Yaris.htm

extremely interesting

btw the VVT-i is always engaged it never kicks turns on or turns off unlike the V-tec

what your thinking of VVTL-i now that has to be about 6K rpm to get into the second set of cam lobes ;)

The car pings because the bB ecu is the OBDII system and your stock 2006 ECU is CAN control.

I am surprised the car runs at all.

Do you remember what model that ECU u have comes from? Ncp30 ncp31?

I wouldn't wait for a reply...it's a 16 year old thread and the user you asked the question of hasn't logged in since 2009.

fpresiado

Do you know which one I need to get?
