Hi all
Have Any of you used or know of a dbw controller that could be used together with vems ?
Thanks
Skassa
I would never work with a DBW controller that is standalone and takes orders over CAN or anything similar, you simply never know what could happen and how the controller would react when there are issues in signaling and such.
I made my version for one car

also one more solution

i could really use this, so i could change the ecu in some of the newer subaru´s , Impreza STI + Forester, but also so i can use a dbw complete manifold,
There is one made for the subaru´s in Aus, but its 450$, but that is a complete standalone with mapping software, and for the vems , i could use the tps output from the pedal sensor, this have built in safety,
but its still recommended for none moving engines :)
I assume that is "if anything happens" , that there is that recommended text
MWfire, is it for a costumers car you have made that controller?
Thanks,
Skassa
So far it works great, but i didn't finished all things(i was working on cdi, mapping lot of cars). So yet is only for me.
I have used pololu jrk controler for throttle control few times, but it has not any settings for idle, so idle valve needed aditionaly
btw it would be great if vems could have 0-5v output, maybe there is any chip who can be used instead of one wire interface? it could work with pololu.
Looks like vems is almost ready for dbw ,
Anyone know what input and outputs the Can be used on the pcb ?
I''m ready to test on Subaru's :)
ok, now we have drive by wire, that's good, controlled from 6-7 injector channel, that's bad if you want to start v8 engine with that. so, is there any possibility with newer firmwares to use any other output for that? thanks. I'm starting mercedes amg v8 soon, so I'm intrested how to use injector channels, make it 2 injectors on channel or wait some time :)

Yes, you can use pwm for injectors. So no problem for v8.

but if we try to make it sequential, then it's not enough outputs :)

You have 8 injectors drivers + injector pwm driver. So, yes you can make v8 sequential and have DBW.

ok, how? last time I have got assembled vems with dbw in box it used 6-7 injector channels. one channel cut before the injector driver chip. so how it must be connected? it would be nice to get more detailed instructions :)
someone?
yellow area is pwn output.
(http://i40.tinypic.com/2e1a8fc.png)
I can add you H bridge for DBW using that output. From where are you?
I am interested how to do it by myself, because I have one dbw box unused, i just need to prepare ecu for that and I want to do it by myself ;) yes, this is OC0 14 atmega pin, so I just need to connect something like injector bridge driver from here? http://www.digikey.com/product-detail/en/IXDN404SI/IXDN404SI-ND/463718
and then http://s10.postimg.org/hglxak4dl/DSC_1074.jpg ?
can you give me some detailed instructions?
found this topic, http://www.vemssupport.com/forum/index.php/topic,445.30.html it explains everything a little bit :)
But be careful, that pin can't handle more than 5V, and can't source/sink more than 20mA.
ok I'll try, btw, what can I use instead of IXDN404SI, because I cant get it in my country
That chip isn't good for DBW, i builded my own H bridge with 15A mosfets.

ok, vems box with dbw which I have is made: That chip pin 4 pwm signal, then 5 pin----> resistor---->box with mosfets, pin 7 ----->resistor---->box with mosfets. pin 5 and 2 connected together with wire. so that ixd chip works only like small amp switch, thinking with who I can replace it :)

you can use SN754410 and two N mosfets and two P mosfets(i use irf540 and irf9540)
thanks for the help ;) it works :D
Anybody used this product for DBW - https://shop.vems.hu/catalog/bridgeoutputdriver-p-185.html
How to connect it.

as I remember I can't get DBW and low z injectors on pwm at one time?
Resurrecting this topic.
I would like to implement DBW in my '67 911 (to get rid of the long cable to the back of the engine) and I am using E46 M3 throttle pedal and ITB actuator. All the sensors are correct. But I would rather not have separate box just for DBW, would like to put the H-bridge in the VEMS box.
Problem is I have no idea what and where to connect, would anybody make a small schematic for it?
Thanks!
You can thake pwm signal form 8 resistors before injectors drivers.
Ok, but sadly I have no idea which FETs to use and how to connect them....
Hello Peep,
Why try to reinvent the wheel? Just order a bridgedriver from the webshop, take it apart and mount it in the same case :)
