    Throttle body and potentiometer electricals (F60/G69).

    Hello friends.
    Found a manual of mecanica of the car in Spanish .
    In the manual he says that potenciometer to total load must have a resistance of 3.6 K ohms, my potenciometer has 2.6 K ohms to total load.
    It is reason so that there is not sufficient pressure?

      Yes that is a common problem with the throttle pot.
      If the ECU doesn't see wide open throttle it won't give overboost.

          Today, I have disassembled potentiometer ( F60/ G69 ) .
          I have opened it and I cleaned on the inside, the tracks by where run guis were dirty, of all ways when I have put it with the open Throttle full, the resistance was of 2,69K Ohmns.....
          Somebody can say to me if this value is sufficient or if he is not correct ?????.
          Some of you whom the car close has to measure this value?????

              3600 ohms on wide open throttle is correct.

                Then but which it gives absolutely with the open valve he is 2.69 H Ohmms.
                I must replace it ?????

                  I need confirmation.

                  I have bought new potenciometer and the resistance of the new one is minor who the one of the old one.
                  New, opened the valve, 2.60 Ohms
                  My potenciometer old, opened the valve 2.68 Ohms
                  The one of a friend who has 2.88 ABY Ohms

                  It can be defective the one that I have bought new?

                    Carlos. I would look elsewhere for your lack of boost. My throttle pot does not go up to 3,600 ohm - I understand that the ECU looks at the "relativity" between off idle and full open rather than absolute values. Can you be more specific about the lack of boost - have you got a gauge fitted ? What happens when you give it full throttle ?
                    How does the car behave on slowing down ?

                      I bought a new one last year because the old one was only 2,6. ohm and the new one made also 2,6 ohm
                      test the one from my friend S2 and also 2,72 ohm
                      So i think the right up about 3,6 ohm is wrong may be the guy tip 3 instead of 2

                        thanks to answer James



                        TI made reprogramming with Paul, but bar does not arrive the pressure at 1.4 as Paul says.
                        I only reach 1.3 bar in 4 gear to 60 Km/h with regulating valve flood and making pulls. I have changed and reviewed sleeves, I have I throw pressure test circuit, I have reviewed everything to it and asi the car with the regulating valve flood even makes a little false. I must say that this week I have put the DV new also.
                        Also I must emphasize that the car goes very well, smooth.

                        My question for you that to know much, is:

                        That resistance in Ohmns has yours potenciometer?
                        This defective the one that I have bought or this good.
