Poor Quick Shifter Performance Connected to Akra engine map

I had my KTM dealer install the Akrapovic Evolution full exhaust system on my 2020 790 Duke at the same time I had it in for its (first) 600-mile service. The dealer loaded the Akra engine map too. I left from the shop and immediately observed the quick upshifter wasn't working 'right.' While on throttle, the ignition is so delayed after upshift the front end dives and gives an abrupt lurch when power returns. Quick downshift stopped working altogether; soft downward pressure on the shifter does nothing. Should be noted it worked marvelously before this shop visit.

I returned to the shop right then. They called KTM and reported that the Akra map delays ignition "5-10 milliseconds" over stock map and there's nothing that can be done about it. No comment on losing downshift capabilities.

I'm beyond disappointed with this explanation and the result from installing an official KTM aftermarket part. The new pipe sounds amazing and it's got great power, but losing the quickshifter isn't an acceptable trade off.

Anyone else experienced this? Any suggestions for how to fix this?

Id be surprised if the Akra map caused the shifter blipper problem?

Did you get the dealer to re-calibrate the quick shifter?

I'm not - fitting the COOBER made a huge difference to the quickshifter. Remove COOBER - quickshifter not as good - refit COOBER - better. Well better for me anyway. It's all about ignition mapping.

No; I didn't think to ask, and the dealer didn't suggest it. They went straight to the phone with KTM and got an ignition timing/map answer.

The QS is adjustable, it's on the first service checklist for them to do in fact. I'd just ask them to remove the 5-10ms delay and well, not sure about the auto-blip downshift issue but I'd be REALLY pissed if I lost that mod myself.

Keep us posted!

I wish. I just want to get in a couple more R&D rides so I can hit them with my attack questions. Some things it really does do well - others seem to be less obviously better, actually almost worst.

tbh - In track mode I think the better solution is to switch QS mode off and use the clutch lever. Even with COOBER. This may also apply to the AKRA tune.

Seems a bit lumpier in traffic etc with the COOBER in Sport Mode when the ambient temp is lowish. Needs a little more revving. Some odd thoughts I need to observe again before writing. But the ruddy weather is really starting to annoy me.

Small steps - Day by Day.

Just west of Madrid . Had snow yesterday. And today it's been peeing down. We're at almost 800m up so it gets chilly. I'm older and I don't like it. My riding day is usually Thursday.

Worst has been very low cloud - basically like thick and COLD fog. Usually I would have been riding all December but it's been a bad year.
