MSS54 Help Please

[superleggeram3]

I am looking to run an aftermarket pedal box in my E30 S54 swap and I was wanting to know if anyone knew the output signal for each channel on the DBW pedal

In other words, for ECU pin 8 and 9 0-5v and 5-0v respectively or 0-5v and 0-2.5v respectively.

Ive tried to do some research and some say one channel is half the voltage of the other and some sources seem to suggest they are opposite. Anyone know ?

DBW Pin out I believe corresponds as follows:
1 - Gnd 1 - Brn/Grn - ECU PIN 7
2 - Gnd 2 - Brn - ECU PIN 12
3 - VCC 2 - Yel/Grn - ECI PIN 14
4 - Sig 1 - Wht - ECU PIN 8
5 - VCC 1 - Yel - ECU PIN 9
6 - Sig 2 - Wht/Grn - ECU PIN 13

Solved if anyone is interested.

The two channels on the electronic pedal (PWG) are 0-5v and 0-2.5v.

The thorttle (EDK) is 0-5v and 5-0v.

So what did you need this for? Is there an aftermarket pedal which you can configure to the specs?

As part of my conversion I wanted to run an aftermarket three pedal box (more for ergonomics) as using the standard e46 dbw pedal isnt necessarily the best matching with a two pedal box.

So the information above was to ensure that I could use a three pedal box from OBP and use their house potentiometer - which turns out I can and so can ditch the e46 dbw pedal.

Some mapping of the DBW is required to make it feel right but that is easily done using the ecuworx tool which is only £20 for a license - not to mention all the other features you get as part of the tool.
