Closed loop shifting?

Postby Mobne_s13 » Fri Nov 09, 2018 6:03 pm

Is this being worked on?

When running sequential dogbox or dct gearbox you want the ecu to revmatch downshifts or at least make a programmed throttle blip to help with not loosing traction in the downshifts.

The ecu knows when you down shift, because the left downshift paddle is always the same, same as it can flatshift when upshifting with the right paddle.

This has been asked for before I know that but I’m curious if it’s in its way or not.

Many people run sequential gearboxes.
Motec does this, so it should be possible for the elite also??

It came out a few firmware versions ago. Pick Load Cell as the input and Closed Loop is an option.

Throttle Blipping is not in there yet. Hopefully not too long before they add it. Currently you have to do this with the idle system.

What exactly does the closed loop shifting do if it’s not revmatching/blips on downshifts to prevent wheel lockup?

The flatshift for upshifting is already supported.

Please clarify for me, I’m really new to sequential gearboxes with Haltech.

Blipping is being worked on as its own function, but for now can be done with generic tables. Covered in one of the other threads how to do it.

Yeah i know you told me before. I was just curious what the closed loop Shifting does now, if it’s not revmatching? Or did you mean that you could make blips as we talked about before?

Thanks :)
