mass air flow circuit p0100 after changing the turbine

[dariuccio]

who knows? if I can solve my problem;
after the installation of the gtb1446vz of the bravo 1.6 120 hp I find myself with this problem, in practice, when I pull the speed to 4000 rpm
turns on for an instant, the malfunction indicator light engine (car with spanner), when I go down, do not accelerate but the engine brake light is solid, then it turns off after driving several miles, and in the diagnosis says "mass air flow circuit".
now I am wondering if the mass air flow sensor ? went the light turns off and then on the corsa c when ? the mass air flow sensor does not work, you turn on another
spy, if I had some wire, maybe that fake contact would not be so predictable in the light; you want to see what I need to change something in the ecu?I hope in many of your responses to me on the nerves is light because the machine does not go into recovery

on that machine, and that engine

Having changed the turbine you have to rescale the whole curve of the mass air flow sensor in the map. It often happens even when the distance from the variable geometry controlled wastegate to the contrary then mechanically.

thanks danny, if you place the map could you help me to find it? for me, those lines are all the same!

you will earn the other horses in this way?

I ? 've read that pu? also give an error why? the measured values are too discordati from those projected / goal.
Then you've changed the turbine, not the mass air flow sensor, for which the linearization should remain the same. According to me the problem ? the turbine responds too differently from that of the series, and if for let's say 100% gas and 4000 rpm are expected to 1 Bar, maybe with the new turbine, you have 1.2, is not enough why? go into recovery, but remains long enough, why? the ecu notices that something is wrong. It is only a guess, I don't know that ecu

[dariuccio]

I mounted the mass air flow sensor of the punto 1.9 jtd but I've done it before changing the turbine and I have never had that problem

[dariuccio]

the ecu ? the classic marelli mjet as the point, panda,y...

[alien78]

but the car is fine?

[dariuccio]

certainly, that is only light to me on the nerves, and after that you turn on and off two times, the third time you turn on another light that does not ? the machine with the
key English but you turn on the engine failure and that I have to turn off with the diagnosis why? does not go away by itself
