DBW in real world?

[gregpe]

Stop writing, and start learning.

Well said...
read, learn if you can't afford to use qualified help..

[bmwmaster]

I don't have any problem to read and learn. But can you tell me a source where to get information about DBW calibration?
I thought this topic is so special that i can't find something. Especially when it gets to calibration and programming.
But this is another topic.

Karel when you start writing about what is efficient and support you should expect to get an answer with my point of view. Otherways i shurely wouldn't write it down
and myabe would have more time to learn

But at the end it is not interesting to write about this anymore here.

Also i think this has nothing to do with afford. Even when i would like to pay for it I think I couldn't find anyone who would do the job easily. Like it was written before some parameters have to be measured
and adjusted to emu.

Thanks for the info jadzwin, i will send the throttlebody to ecumaster. Its not a problem at all and thanks for support.

Everybody can't be a "tuner" If some one want's to learn then the hard way is the best.

To move this thread along!......

Has anyone tried connecting 2 x e-throttle bodies in parallel and just using the feedback from one?

I have heard of people doing this with other brand ecu, technically not ideal but sounds like it works ok in reality

i think this is based on assumption that both of them are exactly the same , the same spring , friction ect.. i wouldn't really go this way... throttle is safety crucial element and i would not take a risk run it that way..
perhaps in black could be it possible and run external module but all strategy would need to be added to software..

[Jadzwin]

Will not work

[RHD]

I have heard people doing this with other brand ECU, in practice the throttle returns to 0% very regularly so maybe they rely on that to constantly re-synchronize them


Is there any solution that will work? (other than waiting for the pro)

maybe 2 x DBW modules connected to the same emu OP??

I think the problem is not with the output, but with the closed loop.

If you set duty 50% to one TB it will open to 40% and other 45% , but if you have closed loop control, you know how far it is open and you can correct it.

Ithink only way to sync 2 TB will be mechanical link.

never used but this may work...

thank you i will pass this info on!

We can measure the spring force and static friction.

How long will it take to do the setup for a throttle if i send it to Ecumaster?
and what is the price for doing this.

[Jadzwin]

It is free of charge. Several days

[shrek69]

Sent it today....hope you can do setup

I am in the final planning stages of my wiring.. The one part i'm confused about is DBW.. I am using a VVTI 1JZ with factory DBW throttlebody. The motor is going in an E46 with EMU Black. Do I wire the BMW pedal into the TPS input and wire the throttle motor up to the H-Bridge as depicted in the manual?

Any input is greatly appreciated!

[Karel]

Yes you need
TPS - throttle plate sensor
PPS - pedal position sensor
and the motor + and -
some of Toyota Throttle bodies are using also magnetic clutch..... i use it on my 2JZ-VVTi.... works great.

[0martin0]

Karel its not realy clear, if it is same as for EMU, then:

Pedal has to be wired to TPS input

And throttle position sensor has to be wired to spare analog input and then configured in dbw menu

This is exactly what I was looking for. Thanks!

[0martin0]

But be careful! Im not sure about BLACK, what i wrote is for EMU

It will be bench tested and TB sent off to get calibrated.
