Strange push on the 2800rpm

[bravosport150]

Guys I'm noticing this thing: in practice, at a certain point, when I accelerate I hear like a knock/push/pulse about 2800rpm then vanishes immediately and continues to progress normally in the acceleration how he was doing, I don't know how to explain it...according to you, what can? be?

I just did the test to turn off the machine, check the position of the shaft of the turbine with respect to the actuator of the variable geometry, then I turned the key, but without putting it in the bike and the key turned I saw that the post was moved, so I exclude that it depends on the geometry variable, why? the spindle runs quietly, or should I check something else? Also with MES if I make the control of the adjustment of the variable geometry known that the shaft enters and exits.


As you well know, I have the car mapped for? I also try to put back the original map, and felt a little less thrust, but c'?!


what might be the result?

Do not take it personal, but do you ? gi? was said in all the ways, the system of the failure, that you d? the power plant, then if you still have this "problem" we'll talk later...

[bravosport150]

ok was to understand, in the sense that I read of the valves in the game I thought they could be charged or the pierburg!

[SandroMarciano]

Currently, the reason why pi? likely, because that also generates a failure ? the power supply system.

ok then, let's stop here, as soon as I solve the power supply, let if be also this issue, thanks guys

check the rail pressure sensor

I gi? changed!

Sorry of what machine are we talking about?

[hyrosat]

Even with MES if I make the control of the adjustment of the variable geometry known that the shaft goes in and out.

Good where can I find this command on the mes that I want to try it too?

thanks

we are talking about the Fiat Bravo 1.9 Mjet 150 hp

You'll find him in the actuators in the engine chamber to the test for the wastegate!
