theres more then one type of fuel cut some systems are completely off some cut a % of fuel, fuel cut is just that cutting fuel no one specified exactly how much which is why i specifically stated several times the only way for it to be remotely safe is completely turning it off. i didnt mess with the utec i had long enough to know what it used i wouldnt make a comment like that if i hadnt interacted with systems in the past which use a percentage cut.

if thats how the utec does it then so be it but saying that fuel cut is always turning the injector off isnt always true. i can initiate different types of fuel cuts on the infinity if i wanted to for different engine protection features as just one prime example. most over run fuel cuts are similar they use a percentage fuel cut to bring engine speed back down.

It seems that you are not understanding what fuel cut is. Fuel cut means the injection has been completely shut off. There is no detonation because there is nothing to detonate. Your engine becomes an air pump that is only spinning because the drivetrain is engaged. There is no combustion to cool or detonate. No fuel was injected. There is nothing to worry about. I bang fuel cut all day everyday for years and years and years... Longer than 99% of other built VQs ever even run. No problems, because no detonation, because no injection.

That's probably very wrong. I have never heard of a system running an engine lean as a means to reduce rpm or load. That sounds entirely ridiculous. I will need to see evidence of this to believe a word of it. Who on earth would lean an engine out as a form of over boost protection? Lol.. No.. I don't think anyone is doing that with any system. If you have a system that even offers "lean burn" as your form of overboost protection, you need a new system ASAP

i didnt say i ran it i said alot of systems have the option.......... you can set up a table in both the haltech and the infinity if you want to, pro efi as well if you really wanted to. mazda factory fuel cut rev limiter is partial cut, 80s GM vehicles where partial fuel cut for rpm limits, one of the reason msd boxs continued to be so popular. ANY softcut that uses fuel is a % reduction not a straight turn off, thats a hard cut. two steps often cut fuel by a % as well as does anti lag since completely turning off fuel wont allow them to generate boost. your logic is flawed and wrong.

this is how many people have blown engines bouncing off factory rev limiters

you should reference here to links websites the differences between soft and hard cuts/limits

This all some twilight zone talk. You gotta re-read about soft and hard cuts and anti lag. Fuel cut is is fuel cut. You can program it 100 ways but if the fuels cut then its cut... Hence the use of the word "cut"

oh really huh
The soft limit is designed to reduce power to smooth the transition to the hard limit
If the hard limit is reached the engine output will stop entirely as the ECU will cut all fuel and ignition events
those are whats relevant here since link cuts ignition for there limiters.

a hard cut is complete elimination, not a soft cut a soft cut is partial elimination through various strategy, one of those strategy's is fuel reduction AKA CUTTING fuel. dont blame me that you dont have a working knowledge of definitions.

I love how you didn't quote the sentence from that paragraph that tells you exactly why you're wrong. Smooth.

oh you mean the section talking about how link uses ignition cut? yes because bringing up the ignition system in someone being wrong about fuel system operation is so entirely relevant. its ok we can see your wrong and dont like your wrong and spoke up without having adequate experience on other systems to know if what you where saying is true or not and now your upset and trying to save face.

have fun with that my point is proven that your plain wrong and 1) cut is any reduction despite what ever fantasy land you wish it to be and in the real world real people refer to cut as a reduction period.

2) systems do indeed exist with partial fuel cuts not complete injector deactivation(thats the word your looking for DEACTIVATION not CUT) soooooo you arnt correct on anything you have attempted to turn this into an argument about. you can keep on going attempting to win and looking foolish though

says the guy who claims the dictionary backs him up yet no such thing.............. and provides no exert delusional much? the only person here refusing to read is you and now your upset you got called out on it.

people totally believe you when you simply come out with "it is this way because i say so and im not providing anything to back my statement up"

You're the one who posted their ignition cut as you're relevant link. I like how you get to pick and choose what is relevant.

We will see who is foolish as you learn more.

You can play internet debate games all you want. But your completely ridiculous. Spread whatever misinformation makes you feel useful.

i posted a link in regards to the differences between a soft and hard cut, reading comprehension you need skills in it. anyone else who reads this will see exactly that.

im still waiting for you to show me how im wrong? you have provided exactly, oh yes 0 evidence to back that up. lemme guess google is working slow for you today though right? so mr check book tuner was wrong on something and since he has no real experience on anything else he needs to try and desperately find someone else experiences to try and prove me wrong which isnt going to happen.

You are the one making absurd claims about leaning out engines for overboost protection, and completely inaccurate descriptions of soft and hard cuts. Cut is
Cut. Nobody said 20% cut, they said cut. You can choose to interpret it as you like, it's not my problem. Hopefully nobody is ever paying you for advice though.

Alright I will lay it out for you, just as your own link you didn't read does. A soft cut alternates between cylinders, and it can skip every other, every other 2, or however it is programmed. But while its cutting, it's a full cut to that cylinder for that cycle. Hard cut is all cylinders cut.

because they exists prove me other wise

and cut DOES NOT mean compelte removal i just provided you a DOZEN definitions that say your wrong on that and a CUT is a REDUCTION. the people who pay me will actually get quality cars because i can at least differentiate the different meanings in words unlike you. again the word your looking for is DEACTIVATION ill help you again since apparently they dont have dictionary's, or schools where your from. plain and simple a cut is a reduction not elimination i already proved that with the definition from the DICTIONARY.

lemme guess though thats wrong too because you disagree? to bad thats the rules the real world lives by not your fantasy land where things are so because you say so. come back when you bring a valid anything to the table
