got ecu flashed while back, got first proper ride saturday, first thing i noticed instantly was the vastly reduced engine braking on deceleration, roads were a bit wet for full on attack,

There are many things you should notice with a flash. Decreased engine braking shouldn't be one of them.

The fuel injectors are no longer cutting off when you close the throttle during deacell(emissions standard) that's why you are noticing less of an instant engine braking.

Engine braking is caused by the throttle blade closing. When the intake valve and downward moving piston no longer have a means to pull in atmosphere, a increase in vacuum is created causing a "pull" on the piston instead of a "push" that happens during normal combustion.

The fuel injectors are no longer cutting off when you close the throttle during deacell(emissions standard) that's why you are noticing less of an instant engine braking.

Fuel Cuts on Lift w/PAIR:
18 AFR+ = Still is feeding fuel. Why? Analog is working.
16.5 AFR = The backup. Why? 'We take measures to protect the engine from damage.' This reverts to Digital. A sensor is down so one number is calculated not the many a sensor sends in as input. This too limps the ignition. This means not at FULL Power.

Sub Cut on Lift:
Stock = These sub blades that are behind the main blades you control, are controlling the air with an actuator that follows a map and opens and closes per throttle input.

Flashed = The subs are now opened at 100% and you lose this 'engine braking' effect. So if the map is flashed for 100% open ~ No engine brake feel.

It doesn't matter what the secondary plates are doing at anytime in regards to engine braking. If the primary throttle blades are closed then you will have the same engine braking that you have when stock or flashed.

there is definately less engine braking, engine braking was strong before, you notice the front end load up more before the flash

What are “deceleration Maps”? What happens when you adjust or remove fuel injector shut off on deceleration? On most of today’s modern fuel injected sport bikes, the factory shuts the fuel injectors off immediately when the rider lets off of the throttle. They do this, to lower emissions on the vehicle and justify this by saying, fuel is only needed to accelerate. However when the fuel injectors are shut off and stop delivering fuel in such an abrupt method the results are normally not very good on ride-ability. 2 of the main problems that result from this are (1)The bike will have a very choppy on/off throttle control which not only makes for a “jerky” feeling under normal riding conditions but will also significantly upset the chassis during corner entry, corner corrections, and corner exits. We take the time to improve and adjust these deceleration maps that slowly and consistently ramp the fuel down as you let of the throttle making for a smooth and predictable deceleration and/or on/off throttle control. The deceleration can improve track times as much if not more than a quality fuel map. High speed corner entry becomes very smooth and less violent helping the suspension geometry work for the rider instead of against, mid corner throttle corrections are now very linear with reduced ON/OFF throttle jerk, and corner exit is consistent because the fuel is down being increased and decreased in a very linear and cohesive manner.

Just to verify here, are you talking about throttle closed, or partly closed?

when i close the throttle,fully closed, i dont get the instant shut off feeling/engine brake,its a gradual thing versus how it was, instant/abrupt

Maybe it's yer cush drive;)...seriously though....mine after the flash continued to engine brake nicely...it may even have smoothed a bit as well. You have a slipper on yours,right?Could be the flash is affecting the slipper in a small way...not a bad way...mine at throttle,with flash....when I completely close down...she definitely slows predictably...which to me IS nice.I don't get a lurch feeling at all except if I'm like in first at say,4K...then suddenly close....that feels 'factory' to me...which is cool...I don't throttle like that down there much anyway.

Overall...the engine braking with mine works very smooth and strong.

=0 Use more front brake at throttle down....get that old feeling backLOL!!!!!(J/K;)Glad you could get out and finally run;)

I think that's what he's saying, grn. The engine braking is the same, just more smooth and less abrupt. That's how it is for me anyway.

However when the fuel injectors are shut off and stop delivering fuel in such an abrupt method the results are normally not very good on ride-ability.

What is with this injector shutting off stuff. Someone hit the kill switch and tell me the injectors cut off on lift. If I run WOT and lift, my needle points to 18+ AFR and pegs the needle. If I hack the bike, WOT and lift, I am now at 16.5 with PAIR. That means I'm richer before PAIR both in FULL and Backup.

Show me the 'cut off' vs. [what I'd call it a] cut down but not off.

You're set up to do this, go out wot, quick kill switch, quick on. Will your afr gauge detect it if your quick enough on the kill off/on?

What controls the backtorque-limiting clutch ion the 14 R? If it's the ECU, a re-flash could affect it's disengagement.

Centrifugal force and reverse torque activates the slipper. It's all mechanical. ECU and other electronics have noting to do with it.

That clowns website says 'error codes can't be flashed out of the mitsubishi ecu'. I have several happy flash customers that will testify to the contrary. And those codes are not recorded or lurking. They are gone. As to the 'injector shut off', what he is talkin about doesn't apply here to this bike. Just like his 'variable intake phasing'. He is generically slapping descriptions that apply to zx-10's and other bikes etc. Attention to detail. It's kinda important when flashing bikes.

What the fuck is variable intake phasing?

It's a mystery wrapped in a riddle.

What the fuck is variable intake phasing?

That might be the intake cam on a connie, and/or Honda car engines have that same intake phasing idea.

When I lift on a carb style, what happens?
1 I still have vacuum happening as the valves open and close via the rear wheel moving down a steep hill say.
2. I still suck out fuel out of all hole openings down that venturi path no matter the throttle position.
3. I still have fuel pump suction as the cam comes around and pushes that arm feeding the car's carb bowl.
4. I still mimic the carb in every way when I turn to FI. Why? Same lame 4 strokes.
a. Did the fuel cut off carb style? No.
b. Did I have a stumble car wise with the accel pump? No.
c. Did my mechanical/vacuum advance follow my rpm and accelerate away smoothly? If tuned well, yes.
d. Did I have to follow every move the carb makes as in copycat the fuck is up??? Why, yes is my best guess.
e. Did you read some lame asshit on the net one more time? Is use is HA asking me? See me confused with the penultimates and their numbers vs. their theories? Nope.
5. I still do not see a spark or fuel injector coding me via 4 times the unit shuts off. Nope, not on my bike.
6. I still have me falling back on the 3wV. No-short/no-connector out/no wire out is my code about to send one: I lift from 140mph to 10mph and never touch the throttle = I'd burn up the engine all lean @ 189/redline now lift.
7. I still laugHA someone calls the cutoff not milliamp a less fuel cutting down of a cooling agent.
8. I still need to see the ECU cut the fuel pressure and now turn it back on I throttle up as fast as I can. Will I beat the pressure with a WOT vs. a zero pressure to 44 psi in an instant? Or do I hear the pump start priming with the needle swings I turn the key on someone shuts off on lift?
9. I still find not a bit of stumble from one transition to the next no matter the lift or rpm.
10. I still lift on the speed shifting foot part which means: it has to cut the fuel my ass it cuts the fuel off on any bike: sans an eco car.
11. I still lift on limp signals and the fuel never cuts off. Like it cuts off on a motogp bike with the flame shooting out around a corner on lift. Pick the bike that cuts the fuel if it's not the kawi.

I woulnt exactly call Carmo electronics clowns, they have worked with Ten Kate Honda
No Grn , you are really overthinking it, its nothning to do with slipper clutch,
its simply rollibng off the throttle to shut, the bike does not slow as abruptly as before,and its smooooother as a result,
man i used to replace those damn cush every few months on my old yamaha rd 350
i dont want the old feeling back grn, this is better

I thought Ten Kate/Pata was using PECTEL ECU by Cosworth Electronics ? Hmm
Learn something new every day !

It's like he jumbled a bunch of crap together in his description. The injector cut off applies to the say late model zx-10r, not the 14R. Clowns lack attention to detail. If he/she is flashing ecu's and can't match his puzzle pieces, that's clown-ish at least. Lol.

A new brochure states, 'We now keep the port injectors on as the shower injectors kick in.' Ah, was this guy talking about 8 injectors and the tiered set shuts off as the port sets shuts off if the other is running? I'm sure they do not cutoff when under lift.

It's like he jumbled a bunch of crap together in his description

Ever rev the engine, hit the kill switch and hear the unspent fire off with a large backfire thru the exhaust when you snap the kill back on? So if the fuel cuts off and comes on again, where is the pop?

Ever see cars, especially old cars going down a long incline, get back on the gas again? There is this puff of smoke and all is fine as it drives? So those worn valve guides are being sucked on with every intake stroke, but you don't see it like a lift shows. So, would some unspents settle in the pipe like the oil does before you step on the gas again?

Ever come to the conclusion if not viewing some fuel gauge, a timing light, camera aimed at the intake port to find out the answer to convince me/you? I'm the imaginary guy coming up with emission moves and if I understand the cat converter, it takes heat to convert. So I'm going to shut off the fuel on lift so the cat cools down for a second and that's seconds of escaping emissions hello?

Okay....I didn't realize you LIKED it as is now...and I probably DO overthink things.....my bad;)Glad you're enjoying yer rocketship.How's the shift feel now?Gotten any better?Anyway....take care Mo.

they are, i think, worked with carmo few years back, think won supersport 600

possibly lost in translation, from dutch to the queens english

yo, the shift is still as it was, maybe im supersensitive to stuff
had 2 zx12r prior rto zx14, engaging 1st was always smooth, never a thud,wallop,clatter bang, ever!
but like everything, you get acustomed and it soon becomes the norm
