Yamaha R1 Fly by Wire and Variable Velocity Stacks

[stevegibson]

Is there any literature around on how to connect and configure the 2007-2008 R1 fly-by-wire and variable velocity stacks?

Thanks

I am interested too...

Bumpety - Bump.

Anyone got any info?

Thanks

Your motec dealer will give you the PID's for the DBW.
Don't use the ones from the R6 file.

Wiring will be as the R6 file though.

Aux 1 & 2 drive the throttles
2x AV in for TPS and 2x AV for Driver throttle TPD

Secondary intakes as in attached pdf.

Nice one thanks!!

Here is a later version of the velocity stack control document. There was a mistake on the Aux3 polarity on page 4.

Back to hijacking the right thread...

So there is a connector with a red and a black wire going into the servo.
So Aux7 and Aux8 go to this red wire according to the documentation.

Does this affect being able to use 8 injectors, with each injector on a separate injector circuit?

I assume that the current needed for the servo is small enough to not be a worry, or is that why 2 aux outputs are used?

Hi,

look at the pdf file page 2, you'll find the explanation about the use of both Aux outputs:

"As MoTeC M800/M880 ECU’s (herewith referred to as ‘the ECU’) have only one H Bridge it is normally necessary to use an
additional control unit for one of the servo motors (a MoTeC DBW4).
This document describes how the ECU can be setup to control variable velocity stacks without the use of the dedicated H Bridge
circuitry (Aux1 and Aux2), thus leaving the H Bridge free to run the DBW."

Thanks dudule01 - But I am still half lost...
The TB I have the older drive by cable version.
So not quite sure why I need 2 Aux outputs hooked up?
The timer I get.
Having an one aux table for enable and one for disable to do the hysterysis I get and Nitrous I understand.

Probably just as important is for me to understand the idle circuit as it is drive by cable.
