View The Full Version : question on the cutt-off
hello guys,I have question to ask about the cut-off...paralando of a system to petrol (turbo), of course,and "editable"???and can moddare this map? how do I find it in 2d? regardless of the ecu..... I would like to recreate the effect, "bang bang" and I thought,do release the gas (when in the cutt off) injection of a minimum quantity of gas in such a way that when it comes into contact with the collectors of the hot,fire, and re-create this effect...
on the rally cars use it to limit the turbolag,and I know that the operation and then more complex. I would like to re-create a similar effect... and feasible according to you? thanks!!
that surely ? ricreabile for? I don't know if it is possible on the stock ecu, I've seen it on a astra and a subaru, but who had the ecu-specific competition, and not the original.

thanks for the reply! I have seen it from some professionals even on the stock ecu, I'd like to know how to re-create this condition... let's wait for the opinion of some expert who may have already had the opportunity to work in this sense;)
the operation ? so about the car rally and the race in general:
The system really is? it's called ALS or anti-lag-system
Its operation ? quite simple:injectors mounted upstream of the compressor as soon as you release the gas, and the system ? inserted inject directly in the collector of the benza,the latter in contact with the pipes of the hot turn on immediately and produces exhaust gases a little as if the scheme were not to be lowered ,with this esamotage the turbo continues to spin anke gas left, and then delete the delay of the turbo when it is pressed again, the gas, and serves the max pressure.

I knew instead that was done a bypass on the discharge and in the discharge phase gl iiniettori inietavano a certain amount of gasoline so that it turn in the manifolds and just keep in the scheme of the turbo... but I would like to know also what the ec behind, and how to re-create it;)
fas2t the system of by-pass air in the hills of the exhaust ? a FTA...but it is called "fan" ? it was first used by audi for its rally car....this system uses the concept of the turbine engine, aircraft...? one other thing....
the bang-bang traditional f? otherwise...what? with throttle fully closed, the stepper motor, idle opens completely bypassing the throttle to pass air at the same time? the injectors continue to inject benza but,just to complicate things,the ignition advance is retarded to a lot of fars? all this mixture of air-benza comes unburned to the hills, hot and incendiandosi to their contact with the effect you tried...you'll understand now that you do not ? very easy to do, and especially not all ecu's allow this type of operation....on the marelli 4F, for example, can you? do...
I just wanted to add that for a road car ? not advisable to do so for a number of reasons but mainly because? drive on the roads of all igiorni with a car that spits flames from the exhaust ready to escape from under the seats to the slightest pressure of the gas...no ? the maximum....

I agree with you, munro, but you see I want to learn because I'd like to try here is, as you say,it would be to do disinseriebile, or even better, can be activated only by certain rpm ( my friend had on the grande punto abarth from 4000 rpm and up)....I fact I would like to try on bosh me7.9.10...
fas2t this system is adopted to reduce the response delay of the turbo in the open-close throttle, especially when mounting of the turbines pretty big....you will understand, therefore, that a system of gnenre that activates at 4000 rpm when the turbo I think ? already under pressure, it means absolutely nothing....if anything the f? the minimum rpm for a certain range of rpm for the speech that you accenavo a moment ago....one of the many cons of this system for? ? we want to manifolds, turbine the turbo itself, and the entire exhaust system that can withstand the enormous temperatures that are reached when it enters the function, the bang... besides, the engine must be developed for this type of system....senn? you're always in the middle of a road....

I have large turbine exhaust skat and tutot the rest....I have not told you of wanting to bang a real...something similar to do the scene,to try...but I have to not do a stage of the wrc with the coffee machine...
I forgot to tell you that, for example, the rally car that have the anti-lag replace, on average, a turbo every 20 hours...
and of course those are not the turbines of the series..indeed..very often are developed precisely for this type of use...
so I think this system on a turbo series realize drastically the life of this and not only.....

what car are we talking about?? T-jet fiat?
Forget about completely of the engine brake unless you create a incoming air directly on the exhaust manifold is controlled by a solenoid valve that you have to manage together with advances(in this case delay) and the time of injection, then open the large air intakes in the engine compartment why? the temperatures go to the stars.
I remember that on the toyota wrc is coming to 1,5-1,8-pressure to a minimum with the als switched on, with a jackknife, you ran the ****s als on different positions, the departures were burning.
a few years f? from a burglary in my area, it managed to recover an ecu marelli iaw 4f a deltone the accident that I knew I was prepared by a well-known coach emiliano...Gamberini...the ecu ? ended up under a cuop? turbo 16v and had the program the anti-lag....the car at idle was quiet but as it was 1500 rpm, it began to spit fire and flames from the exhaust and the press turbo from a stop,I repeat, from a standstill,you stabilizzava on 1.4 bar!!! in spite of the coup? it had a turbine T35 junction escort cosworth bilianciata to 0.5 grams to 150,000 rpm this even after 400 km as part of a package....not to mention the collectors reduced to a sieve and of the one terminal remus on the discharge line completely broke out....after this the car ? back in the configuration totally ori but despite this, even after 100km the engine fell out(head gasket) to the enormous stress due to ALS...
now fa2st if you want to ruin an engine to the scene, I'm not interested in....for? then not to say that you've been warned...
p.s:fa2st if you want to hear bangs from the exhaust in a benz just to turn the car or very lean in advance with a p? the top decelerazzione or you can grease the afr under load in such a way that when you raise the foot all the benza more in the exhaust explodes....
also if you want to see real flames without risking anything, and without adapting the engine,spending a lot of money,there are commercially available cleaning kit....

you must give a bucket of gasoline,and retard the ignition in an exaggerated fashion. I took it many years ago on a Volvo 480. consumption windfall manifold and turbo glowing. I advise you to do it only for the purposes for competitions and for short periods

here is munro,just do as you say in deceleration.... I know very well that the real bang bang and destructive to turbomacchina,exhaust valves, etc, etc...or want to do such a thing,not a bang bang! the car in question and a grande punto abarth 155 hp
I believe that the user bean you can route on the strategy to adopt in the ecu...try to feel it...

thanks a lot!
on the ME9 some chiptuners with the zebetei dodecagonal are able to activate launch control... that is more or less an effect almost similar to a bang-bang...

You can do the mechanical mind! with pop-off recycling within connected between the intake and exhaust..
identical to the bang-bang but mecanico...

but it serves grease from the map, anyway, right?? dov and the map of the cutt off on the m3 7.9.10

you can't? do in the t-jet because? the management solenoid valve shut-off
In systems with turbo charging when you quit abruptly on the butterfly (releases) to form an overpressure in the duct upstream of the throttle valve, which tends to slow the impeller of the compressor by establishing strong vibrations and noise.
The shut-off valve allows the recirculation of air from downstream to upstream of the compressor, reducing the pressure in the duct.
The control unit directly controls the shut-off valve as a function of:
- load engine
- atmospheric pressure
- pressure turbocharger.
I've put the mechanics , why? the shut-off of the series with low-pressure turbo-high, tear the membrane and lose pressure...

first of all, to start I would try to understand how much ? possible to delay the ignition, that would make a try retarding the ignition a medium-high rpm and low load, and try in the deceleration is more or less intense to see what happens

I would try also to do it :D but someone should explain gentimente as....

if placed in the file and/or the map in advance and, if necessary, the map that manages the charging times of the reels you will see that together we combine something
