clarification on maps turbo opel corsa 1.3 mjet 90hp

[rego88]

Pict the westgate, so that when put in motion, the pierburg the withdraws all the way to the end of the stroke of the screw in recovery, and when it releases the spring of the westgate open it completely. unfortunately ? a p? complicated to explain on the internet? penzo that have been clear enough.
I forgot...do not change down the pin to recovery with the lock nut!
in any case, already from the original, without touching it should be already ok, and to make its full stroke test of pulling the pin of the westgate, and see if the lever on the giometria opens still more let us know

then.... when the' car l' I turn to a minimum... up to battura of recovery... then see if you get to do the whole run ? impossible.... why? I'm in the makkina.... I repeat... we get.... the cio? if you do not do depression ? the whole long.... but then?? with the duty cycle of the map??? we get to the end of the race?? not c'? way to extend the stroke from the map??? only above 3000 rpm???

rego with the turbine golds to the ground, measure the travel,the travel that is the wastegate from fully closed to fully open
then this race should also be made of the wastegate of the turbine that you have to currently measure carefully, especially in the opening excursion f?....if putting in place the measures of travel of the wastegate still have the same problem then you have to act differently..in practice with the help of someone who accelerate in the machine, you need to observe the wastegate that acceleration of the motor from the latch must be pulled to a win against the down the pin on the hex of the registry but as the spring in the accelerator must give up the wastegate if this is not the case then you must begin to lengthen the wastegate by unscrewing the log on it until the minimum decelerated should be noted that the waste management open....
also I wanted to ask, but has ****s measures the wastegate are of a similar diameter and altezzadelle same??if they differ in size this leads you to problems that you're experiencing that point you should mount the waste ori of the point on the crowd pegeout....

at this point I believe that the problem lies in the "ball" of the wastegate... the ori ? a little more than that peugeot... I do not want the duty cycle of the kkk original is more long to be able to drain the whole of the ball... and in my case it is empty most of the due.... I know that? better if you lose the ball original.... and ritaro as I had already done.... the dipstick all long stops and then I'll do the race at hand and see if he comes to batting.... according to me, it happens with the ball smaller and duty cycle of the original, the race chiamamola in dustria l e lectronics decreases because of the ball more small...

I take this topic very interesting: someone wants to do a post where he explains well how to work a variable geometry turbo, and how the ecu is able to change the geometry on the basis of the schemes? that actuators there are, etc. etc. ... it would be very interesting!

sorry for the ot

try to replace the westgate, but for the moment, do not change any calibration. But where are you? if you are near we see with is the turbine!!!

Then you placed is pressure?

hi james... I'm in the marche... I read that you are of salerno... then lontanucci.... no... not l I arranged still xke I'm doing an upgrade to my car.... 147 1.9 mjet 150 hp... upgrade turbine... collectors... ic.... exhaust finished my I dedicate myself anew to the race!!

[rego88]

with my we are at a good point.... but as I think you know.... ? much more easy to manage a bosch a marelli..... now I devote myself to the race.... in the meantime, I have re-calibrated the wastegate, and I've done a couple of tests.... therefore....
as james, I opened the geometry, when I turn on the makkina, comes fur coat, beaten on the recovery with the lock nut, you just made is changing, it seemed to me that he went, but at this point I just a bit too far open at low rpm.... to high, it should be discreetly, ? much improved after 3,000 rpm, but I don't actually know' how to move to ****llo electronic.... I closed a bit the geometry of the low speed and the car ? improved, but I've noticed that if it sank, the pressure shoots to 1.5 bar.... and if the arrival is gradual up to the met? the accelerator, and then lunge, stabilizes to 1.2 /1.3 bar!!! another thing.... between a change of gear and another.... why? it remains for me very slow to rise pressure????

probably more than the difference of the wastegate, and duty cycle sar? different (the turbine pegeout) ****l angle of the vanes vgt....

yes, yes, ? different... in the first place ? other than the "bowl" of the vgt, and that of the 1.3 mjet nn ? applicable to peugeot, then I noticed that the geometry of that of the 1.3 mjet ? very different from the classical variable geometry!!

[munro]

then to solve the last I see....you practically have to blow only on the map and on the controls pid turbo...
then in what sense is the vgt of the 1.3 ? different from the usual vgt??
