I may have missed it but was a link to your githib posted ?

Is this maybe coming to next bigger firmware update?

Or did someone moved this option to new 202207.1 fw?

Or what do i need to change/move/do to get this work on 202207.1?

Hello, do you intend to update to version 202207? I don't know anything about programming, and I'm in need of a flatshift to AT too, my transmission is slipping a little when shifting at full load.

Any update coming??

Any update coming??

Oh! Nice to see people demanding updates!

Yes, i think I'll be updating/moving to last firmware.
No, I dont think this feature will be in main stream for couple of reasons: very limited amount of users / my sloppy style of pull requests.

By the way, current doubts:
- I doubt if hard cut feature was any useful. I am thinking of leaving only the ignition retard algorithm
-There is a need to do an ignition retard also on downshifts
-Also a kick-down solenoid control should be done via ECU to ensure kick-down using a TPS value, not the press button on the floor.

I think that hard limit is nice, nice "POP" from exhaust when trans is shifting B
I did manage kick-down with VVT table because i dont have VVT in engine... And if you need to use VVT you can use programmable output i think?

i have few questions
first, the RPM DOT logic bothers me. rpm drop will only occur after the transmission has initiated the shift and i see that as a delay, doesn't it cause a problem? could it be better if you use a logic with less delay or is it negligible for the application?

see i have a honda fit AT 5sp and yesterday forum servers were down and i was looking for a solution for the delayed shifting.
so i began looking for a solution and noticed i had 3 solenoids on top of the transmission that operate on a consistent sequence for upshift. so i hotglued solid state hall sensors to each solenoid and wired them to an arduino just to test and did a test sketch on arduino ide with 3 if loops all in each other to finally output on the serial monitor that a upshift occured. it wasnt consistent so i just stopped there because the setup was getto anyway.

now that i came across this, im thinking to use a diffrent logic.
i read somewere months ago that the my oem ecu that still controls the throttle body closes at 25% the throttle body durring the shift to reduce the charge on the powertrain. i dont know if the 25% is true so im going for a ride and datalog and figure out a consistent way to detect shift.

if i dont find it i will try the solenoid logic and use the signal that goes to them and a voltage divider to send an input to an external arduino that will at its turn output when solenoid one engages and reset the output when solenoid 3 engages (when the shift is done)

Any news regarding shifting to automatic transmission?

That would seem a logical choice, but I would add a simple timer for most transmissions that do not have a secondary solenoid action, or if shifts could be tuned with a specific delay, etc. The delay could also be tied to TPS or MAP to indicate current load, shortening or lengthening the delay to best effect. Perhaps a simple 2-point taper. Hmm...

I was thinking of something to cut the ignition or the injectors or both at the same time while some digital input receives 0v-ground and returns to work when the input is disabled, because my automatic transmission when it is in gear time requests a torque reduction by a grounding wire
I would like some opinion to develop this project
thanks
