View The Full Version : Info on torque limiter
Hello all, I have a doubt about the torque limiters in the ecu of my GT 1900 150 HP EDC16C39. I'm just a fan but ? by a p? of time that I lose with the ECM to try to understand something, and in the future maybe optimize my drive. However, my doubt was related to the torque limiters in the ecu ? this is the "torque limiter maximum" and a limiter for each gear.
The values of the limiter in each gear are set to 1000, then I infer that ? as if they were disabled?
If need? I had to limit the torque only in sixth gear, it would be possible? The Cio? if in the "torque limiter massiama" at 2500RPM I 360nm and in the "torque limiter in sixth gear" at 2500RPM I 330nm, how would the ecu?
esguirebbe the new command all the times comes the information of 6 march this.
So if you wanted to solve a problem of the couple exclusively present in sixth gear I could change the parameters only for that condition.

of course, limits to the pi? low. anyway, usually we do the opposite, is limited to the low gears
if we are not indiscrteti, that's you problem in 6 gear?

The reasoning ? correct, and I apply very often, as with the long gears, we have pi? problems at the flywheel, then ? useful to limit the torque in the 6^and 5^in.

This limiter on each and every gear exists on all engines or just the ones with a pair of particularly high? On my 1.3 multijet (200nm) I've always had the impression that in the first two gears, the engine had "less", now I read this thing and I'm thinking...
sometimes actually is used to limit the torque in low gears 1 and 2 or only 1 , when the exchange rate of the limitations of robustness.
in substance ? a method for the preservation of the exchange, as well? as the classic torque limiter you can? consider useful to the preservation of the engine.

My exchange (the classic C510) from what I know holds officially 206nm, and it is said that some engines have also been "voices" to remain within the limits of the transmission. The feeling that I feel I is presented, in particular, immettendomi in a roundabout from a standstill. You get maybe one shot and you can see him to the last; and cos? instead of making the gear change is sweet the second, lunges everything to get rid of the middle, but the engine seems a bit dead in the water. And not ? the effect of the diesel that the walls at the top, or at least I think not. Otherwise, in round pi? large where the engine holds up well in third gear, you leave it with the decision with the provision of full and unobtrusive extension. Feel good about the couple and then the power.
some engines are limited in 1st and 2nd gear and reverse.
for the back ? understandable that you don't need the maximum, but in 1 and 2 often and not just diesel, it limits the torque, even for warranty issues of the exchange.

I'm surprised that this is a surprise.
we must never forget that the electronic devices are tools that are used to operate a mechanical that has certain characteristics , physical dimensions, performance, and that manufacturers determine through this combination of mechanical and electronic features that the model of the car must have.
then, the ecu determines the vehicle but to the contrary ? the car as desired, which determines what needs to be mapped in the ecu.
if we are not indiscrteti, that's you problem in 6 gear?
Quiet, no problem, indeed thank you for the comprehensive answers. Practically everything ? born when I replaced the clutch and I decided to make a change to the Clutch+Flywheel by installing a Flywheel Monomassa. The car goes very well, the only drawback ? in sixth gear at about 2200\2500Rpm if I want to resume with the force she feels a vibration that probably before it was damped by the flywheel. If I want to put the map ORI the thing ? very small and only limited to the range of 2200\2300Rpm. By checking the values of the torque limiter in the original map at about 2250Rpm ? limited to about 350nm. So given that the problem only manifests itself in the Sixth, I wanted to avoid this hassle to be able to reload the map moddata. Among other things, the exchange of the GT ? the C530\6 that should be studied to rule 305nm, I was a species that in the map Ori's original value, and that value is exceeded of about 55nm fabrication, I thought I would find 305 as an upper limit.
Today I reduced the values of the limiter in Sixth gear from 1000 to about 340\350 to verify the problem, in fact I have drastically reduced the vibration only in the deterinata condition. Being a neophyte in the field, for now "giocherello" with the map to me ? been done, just to start to understand something and exclusively for personal knowledge.
I too had the same problem with a 156 1,9 110 hp, which when mapped to had the same problem of vibration in addition to a principle of the slip clutch. I have given weight, but the slip clutch, but by reducing the torque I solved both problems.
only that I preferred to lower the limiter general even why? with the low gears 1 and 2 when I started strong with the steered wheels I had difficulty? to check the steering.

I have already? tried to edit the map with good results, today prover? to further refine the map to eliminate the problem, up to the fifth gear, it seems to me to other problems, even my ? mainly due to the monomassa that dampens less vibration.

well I think it is a problem of the clutch....I also with the 159 I have never suffered from vibration and slip....now with a new clutch if you are on the highway and resume or a 5-or 6 gear from 2000 rpm or even more below....then around 110 to 120 km/h... it vibrates a lot....while from 1 to 4 pulls to the beast without chatter or vibration problems...and yet the couple set ? the same at that rpm in all gears......I think they are the physical limits of their component, perhaps not of very good quality?...why? before with the same map and clutch ori of the car with 70k miles, I had no problem.....of course now I regret not having made a clutch is different.... reinforced....but who knows? if I run....

In fact ? precisely for this reason that I tried the kit monomassa as the clutch and flywheel original have started to give some problems (not to mention the problems of excessive hardening of the pedal that does not depend on the map), the clutch and flywheel the original are not really of very good quality? also according to me. Slips with the new group I have ever had, and if all goes well I solve the vibration, which I think is still due at the rate of exchange does not have a great tolerance.

look, I have mounted a flywheel and clutch derivation coupe t20v, and I had no more no vibration even 6a to 2000 rpm to 1200 rpm if I'm in meta, gas begins to jerk to, but just do gas stops

how to inject with that flywheel? I arrive a little more of the 110mm3, but I also have a gt2256v derivation 2.4 jtd 150hp

damn, and I knew that I had to convert to the monomassa and clutch copper.....everyone was telling me that the machine would have a string of pulls and that would have had a lot more vibration than the bimassa also in walking back to the normal traffic.....instead, already others have told me that ? cos?.....
I think I do...maybe I place my someone that needs to do....I only have 5k miles facts.....maybe even less...
eye to assess everything.
the choice of the monomssa and clutch in copper ? good for use in the performance of the car, but the comfort of driving may be penalized.
the bimassa ? been made to ensure the comfort of the car. less shots with the shots releases.
if you are a guide only goes well the monomassa , but if I usually have passengers (possibly sensitive) currency a good choice.

oh god, I transplanted a 1,3 multijet 90hp on a y with the turbine duchy.....clutch copper.....and went to god....the comfort ? good.....or better, there are no differences in regard to the comfort....

The map I've made, I'm only limited to change the limittori of torque. However, I think it's a 107\108 then 7% in the pi? from 2250rpm, always that you are referring to the amount? of fuel injected.

The fact that the entire group is pi? light makes you feel positively and also the engagement of the clutch ? pi? direct, for? sergiot has all the wrongs. The machine ? definitely the most? noisy, you feel at the minimum a metallic noise than before
and although he does not feel strong vibrations, the difference compared to before ? obvious. I could go back I don't know if I would opt for this kit, the ultimate would be a flywheel, reinforced and lightened, but the costs are a winner.

he makes a noise to a minimum-style ducati, a tinkling
Exactly, but without the dry clutch.... I do not know what the cause, if some part of the exchange or the springs can be slid on the clutch.
tidus1985
23-12-2013, 00:16
no ? the bearing on the clutch pressure plate that vibrates, indeed, when you push the clutch and the force on the pressure the noise stops

If I can give a tip to the vibrations under fire council to check the axle shaft on the gearbox side. It is common on cars fiat group that you ruin the "glass" on the gearbox side cause leakage of grease on the inside, maybe because the headphone route, and you start to feel those vibrations, that may steer a little, or to the right or to the left should tend to decrease.

I believe that under fire is due to the map....why? ori problems there are....
megamind
23-12-2013, 11:48
is under fire often ? the map, I also had I this problem is then solved on the limiters 4th, 5th and 6th gear. At low loads to me slittava on marcie long, from 2000 to 2250 point where I had the maximum fuel and maximum turbo pressure. With the limiters ? everything is ok. In the low gears instead no problem.

23-12-2013, 13:06
it is the same identical problems....cerher? to intervene also I'm on the limiter, gear....

Great, thanks for the info. Reading around the web there were those who spoke of the posts of the change that vibrate, and other stuff related to the exchange, and in fact I was a p? getting worried. For?the behaviour ? just as you say, if you press the clutch it stops making that clinking metal.
PS info, if I wanted to cimentarm in a map from scratch, the values of the ECM Titanium drivers is enough to start doing a decent job? In my current map, there are a lot of things out of the driver and to be honest, the car performs well, then it was just a personal challenge to try to make it a 0.

out drivers for a map deceived then the standard is only the egr and dpf off drivers, dpf through a switch off for your, the rest you need: map pedal, torque limiter, map time, map turbo and rev limiter, map rail, and limiter, the map iq to nm right if you want to do a little ad hoc, and you don't need another part of the egr and dpf, ? all drivers for titanium

Then the driver would be pi? sure enough, aside from the EGR.

But are you sure you do not have dpf?? I've never seen without 150hp...

for the closing with the map of the egr you will find galore of examples here on the forum also addresses it seems to me

I have doubts about the egr as I've written that c'? something also out of the driver to exclude it. Given that who made me the map he gave me a date identical to the original with only the egr excluded, checking on ECM Titanium the difference between the 2 maps ? only in the driver section dedicated to the EGR valve. It was for this that me ? come to doubt, however, I documenter? in the various discussions, even if today I have not had it the ignition lights it errors in diagnosis.
PS MERRY CHRISTMAS TO ALL :)

on the c39 now ? well known that you chide the egr, eliminating the 2 humps strictly out of the driver, i.e. the controls of hysteresis, then turning just the function of the egr, if the person who made the map does not know this type of closing the egr, all using I'd be a little careful, my opinion then obvious
