guide to disabling the butterflies SWIRL engines Alfa MJT

[Errecinque]

Thank you, the address of the cks I understand the speech of the correction, and always hacking to understand and get familiar with the ecm, I Noticed that the cks should be only 4 bits (I'm using the display in 8bit, if I'm wrong correct me), respectively 1FDFFC to 1FDFFF, in fact, by selecting my files, the original and the final area cleared in large part, by selecting the my driver in the ecm, and changing those values by hand to test, those bit the end autocorreggono, but only those bits of them, (selecting the driver for the alfa gt, which from the specifications of the ecm mark as 170cv, but the codes hw and sw are correct, and the file ori, in fact, is in automatic.
Then all the rest of the bit to Drift I just can't understand what they may be.
Anyway I'll keep for good the one bed in the ecu to continue with the future mod!
To increase the horses, of course I would, just to fix that little vacuum at low reggimi, would you like to advise me in metito? of course, getting into a suitable section to talk about it.

We are going too OT...on the forum you will find lots of info on the edc16c8 and c39, you have a lot of material to study. Then, if anything, open your own discussion by posting a map of the opinions. Good study.

Ok thanks again, is there a way to study, the problem is finding the time! Hehe
However, slowly we will understand more and more, the computer does not scare me, being my work.

Hello guys, I muovamente here, given that anvora mom can I view the guide, but studying on the forum managed to locate the area of management of the swirl, and then to reset it in the file that I have on the pc (not yet written into the ecu because I have the swirl removed physically, and the actuator is connected between a bit of KM when the time of the distribution, I want to mount the manifold in aluminum 140cv and remove the actuator, but in this case it is not enough to lead to zero-that area right? I would report the failure, right? Could you give me some advice on what else needs to be reset in order to completely remove the actuator without failure and recovery?
See you soon, greetings.

Hi all, after long time I come back on the forum, in the end, I prepared the file with the management swirl and dtc relating zeroed out, and I wrote it in the ECU, all ok, even from the diagnosis, the actuator is stopped, have not had a chance to try to disconnect it again, but it should be all ok.
The only thing is that I notice a lot of vacuum at low revs, possible that there is a lot of difference without these accursed valves? Solutions in this regard? Wanting to mount the manifold in aluminum, with the swirl (the other model with the upper rod of command so to speak), has the same chance of breaking valves? Or them jumping only the rod of command?
I wanted to mount the manifold in aluminum 140cv without valves when I do the deployment, but now you can taste the difference, you will be forced to intervene on the malpa to fill the vacuum?
Greetings

If you made the change correctly you should have no vacuum, at least some of the swirl is not over in the geometry of the turbine and the te has locked

Hello, for the turbine has been overhauled recently , 12000km about, so the geometry works.
In fact, I had to also enlarge it mechanically because, in practice, au low revs the pressure reached a peak of 2.7 to 2.8 (from diagnosis) and up to 3000giri the machine sembrafa braking, then starting to blow after the 3000giri at the opening of the geometry. With the help of a friend I loose a little bit and in this way the drive is more linear.
However, at low revs seems to be asleep.
I have tried another like mine, same engine, but with an injector that corrected + / - 5 and trouble to go into motion, but he walked pretty darn low, I have seen the performance of the turbo pressure with the diagnosis, and more or less it was like my first to edit it by hand, with many peaks, and the actuator that went down up to 20% off (my first), but my difference is much less.

I suffered the breakup of a swirl, and then have carried out work on the cylinder head, have you also removed the other, only that from that moment, you hear noise from the tappets, I also redid the turbine, but without returning as it once was.

For editing I think I have made it correctly, I can still read this guide, I lowered the curves of the management swirl in 2D.

You say that with the change it should return almost like the original?

but the vacuum low have you noticed after the removal of the swirl mechanically or electrically? it seems to me, d you understand that before you did the mechanical work and after a little editing software...??? when you have noticed the void?

But the connecting Rods are straight????

Sorry if I answer only now, but I have been very busy lately.

The vacuum low I have felt since after that there has put your hand to that mechanic of the workshop that did the work to the cylinder head, after having sucked the swirl, unfortunately I am the damage that has done seriously do not know them, should I open it and check the surprise, with my mechanic, we are left after this cutting I short we decide to disassemble it (even if the belt should I wait even longer, but I guess that can be good even after the next coupon), and check any serious damage, me worried if we had seized some sections of the piston concerned and which has done serious damage.
The change I made a little while ago, alone, but I don't think I notice the difference

*cinqueturbo
Unfortunately not even this I know!
You speak of the piston rods of the pistons? They could suffer with this injury?
What can I say, that makes a lot of noise of the tappets, probably some pumping does not do his duty, or it can also be a valve that opens/closes well?

Known sure that by accelerating gradually up to 2800rpm, it seems choked, then at the opening of the geometry, they resume better, of the night if I have one on the back, with the light of the headlights I see that in the time of the opening of the geometry, but leaves a nice bit of smoke! Then go back "normal", of the day I don't seem to see big clouds of smoke from the mirror, I would see another machine from behind.

good evening,I am a beginner and I would like to know if you know me to recommend a program to eliminate the Swirl on the MJT.
thanks
