Love the way they say it fits but may require dealer programming.

True though FCP say that about their OEM Bosch ones as well and they should know better

Very interesting, they all say "may require dealer programming"

Wonder if they know what they are selling

Had replaced MAF now replaced Throttle Body. The result is; there is no change

The engine started with several big bangs (backfire etc) then went rumbling (oscillating RPM) again.
I let it run for few minutes then it stopped.
I'm attaching 2 printouts.

What am I doing wrong?

Adapatation process. Was it done according to the PDF I attached?

One of the attachments has me confused. It says 99% turbo pressure and 2.7% desired throttle angle. Is the car at idle during this table?

Yes,and it has been on idle since the day I put things back after cleaning my old TB and the PCV. A month ago.

jimmy57 where are you?

When you look at the throttle adapatation in ECM module does it still say that throttle is not adapted?

These are the printout of the reading I get.

You told me that to activate a Bosch (non Magnetti) unit all I had to dowas to clear the code, start the engine, let run for a few minutes then it will set itself.

The codes don't clear. I mean they come back right after they are cleared!

Hi Sergio. You really are having a rough time with this aren't you?

These docs don't show the state of throttle adaptation. The area is in Vehicle Communication and then click Parameters Tab then then the ECM module icon then plus sign to find Adaption Throttle Unit. Double click it. It will then show you the state of the adaptation.

What does yours say Sergio?
