I have a Nissan RB26 Skyline engine and am toying with adding DBW throttle control to link up to a M800 traction control strategy. I think BMW M5 engines have a drive motor that opens their multiple throttles DBW style, if I can adapt that motor to the RB26 what do I need to do potentiometer wise? I have the stock Nissan throttle pot on one end of the throttle shaft arrangement, do I need to add two more separate pots, or are their "combination" pots available? Should I try and find out how BMW do it and try and transfer it along with their throttle pedal pots? I am building stuff into a new race shell over the winter, so now is a good time to try and implement this if possible. I really only want DBW for traction control, is it worth the hassle or is fuel / ignition cut as good and as flexible? Thanks. I am sure the ongoing and excellent TC and Launch control Webinars will cover this, but I want to get cracking now with the hardware if needed and worthwhile

Hi Chris,
Here's the problem.....The PID calibration for a DBW system needs to be done here (by myself or Duane) and these numbers are specific to the DBW system (motor, linkages, butterflies, springs, etc) not just the little electric motor. customized systems is something we don't really want to touch due to all the little refinments that the car manufactureres make to their are usually missed when people make their own system....therefore we are not really allowed to calibrate anything custom......from personal experience I can tell you if it goes wrong it is all a bit ugly. In fact the upgrades can only be sold if we have a serial number of the factory system it is going to control.

Your two options would be graft on an whole BMW six cylinder system and we can give you the set up for.....although the factory system has it's downsides......or put a single throttle body on it and you then have a huge range of options for throttle bodies we have calibrated.

BTW the pedal is pretty simple so there is no real reason to get the matching pedal for a certain throttle body.
