Hi, few days ago I made a map and defappizzare my alfa 159 150 hp (152cv on the bench)
The coach, very smart in my opinion, ? managed to get out almost 30cv in more than the original, and 51nm of torque.
The problem for? ? this, on the tour taxis a wonder without any problem and damage while on the road after a nice pull and a stop at the traffic light, after about 20-30 seconds the car goes into recovery without any warnings. Off on again and again like a bolt of lightning.
Under-diagnosis error P0091 fuel Pressure regulator (inlet of the high pressure pump) Signal is not valid.
In the end I had to settle for a map and more soft with the 15cv in pi (167 about)
Anyway, before this I had tried an additional control unit that gave the early error P0090 error sensor rail pressure, at which point I replaced the sensor with one more new alfa gt with less than 50,000 km. The piece differs only on attack of the plug that you link above, but to the side.
when I changed it, the car has taken place and shot......I remounted for curiosity? the additional control unit and...tadaaaaaaa error P0091 and not more p0090.
Well improvement?!?!?!?!?!?! I don't know.....
the fact is that even at the minimum pressure increase, if schiacciavo the gas pedal at low speeds, from 3? then, as soon as more than 2900 rpm, the car went into recovery, with a resulting error, and the car that was not more.
Anyway, I noticed that if I took the car in those regimes tramquillo without sinking too eper then crush to the fund after the 3000....no damage......
Can???? I don't know
Someone could give me a hand?
Thank you
Michele
