Flat shift works!
So I have been playing around with the flat shift feature and I have to say I really like it. The hardest part is forcing yourself to keep your throttle foot flat on the floor (WOT) when shifting, which is of course completely unnatural. Flat shift requires that WOT is triggered for it to work. If you lift your foot even slightly, and get out of the WOT threshold (also adjustable BTW) then you will hit the rev limiter.
I shot some video of the flat shift while trying out my roll bar camera mount. There are two pulls in the video, 1st-4th. In the second segment on the 2->3 shift I lifted slightly and it overrevs. In the first segment I lifted on the 1->2 shift; it is a hard habit to break. Otherwise it works, and my foot is flat on the floor for each shift. All I am doing is clutching and shifting. It actually makes for a gentle shift, especially in 3rd and higher.
Spark/fuel cut (got a cat), 4500 RPM set point.

Thanks Travis. Yeah it is hard to keep the foot down when your 'muscle memory' is screaming LIFT LIFT! I was tempted to lower the WOT threshold to compensate but I think I'll just keep practicing instead.
Yes the WOT trigger is handled by the Adaptronic based on the TPS sensor. Once the TPS is calibrated, 0%-100% (just like the MS), then there is a settable threshold. It can be >95% which is what I have mine set at IIRC. So any time the TPS is above 95%, the throttle is at 'WOT' and so flagged in the logic.
The same WOT flag is also used in the Adaptronic for A/C compressor cutoff, just like most OEM setups.

It uses the clutch switch at the top of the travel (not the starter lock out switch) so if you just barely press the clutch it will trigger.

Not sure on that. I have read speculation that with the fuel cut only, it is possible to ignite a lean charge in the cylinder if the injection is partially cut. Not sure if this is a big deal or not, so I just cut both to be safe.

Thanks “ZX-TEX” I’ve had my Adaptronic ecu installed for 2 years now but have not bothered to set up the flat shift. Guess what I’ll be doing on the weekend.
