Aspkiller Posted September 6, 2014 Report Share Posted September 6, 2014 I'm running an i88 with a ProShift 3 Paddle Shift system and an EMCO 6 speed sequential gearbox with a 5v pot for gear position output. If I'm understanding all of the shift cut capabilities of the i88, there is no way I can use the i88 in a closed loop mode. It seems everything has to time out, one way or another. It seems the ProShift doesn't have a retard capability and the i88 doesn't have a closed loop capability for retard/restore. Are these correct assumptions? As you currently read gear position from my potentiometer, what are the chances you will be able to modify the gear cut software so it can operate closed loop? Sounds pretty simple to me, but then I'm not the one doing the programming. Thanks, Larry Quote Link to comment Share on other sites More sharing options...
Simon Posted September 8, 2014 Report Share Posted September 8, 2014 Hi Larry We are actually currently doing a bunch of work around the gear cut control to allow a true closed loop control. It is about to enter the testing stage so will still be a good while away. At the moment people are using the geartronics unit as an interface.

Aspkiller Posted September 16, 2014 Author Report Share Posted September 16, 2014 Thanks for the update, Simon. I'll be looking for the announcement that it's ready to go. In the meantime, please be sure to reference ProShift as another very viable package for shifting sequential boxes. I'm currently using the PS3 with my EMCO and find that it is much more efficient than the Geartronics unit (electric vs air pump), due to the duty cycle required by the pump and overall weight of the plumbing system. Also of possible interest is that we have successfully converted a G-Force 4A dog box(and other boxes of similar exterior rail style) to push/pull shifting with a potentiometer, thereby providing gear position. It is also controlled by a PS3 with paddle shifting and auto blipping. Having the cut shut off once the next gear is reached is a necessity (in our opinion) in road racing.
