Throttle problem

Hi again guys; I'm having now a new problem with my throttle because when the turbo begin to make boost, the throttle closes and I don't know how to trick it so I can interrupt the signal from the stock ecu. I will appreciate your help guys. Thanks

You mean it goes into limp mode and the throttle sticks at 15%? Can you describe the problem more thoroughly?

Yeah the throttle sticks and I know it because the BOV actuates before I leave the gas pedal.

Sounds like it's going into limp mode. Check to see if you have air flow too high for TPS as a check engine.

you need to clamp your MAF at 5v if the ecu see's the boost it is going to go into limp

Naw, you just need a reflashed ECU. When you clamp the MAF a whole lot of other things go on that you don't want. I just go in and adjust the MAF/TPS table and it won't throw that CEL again.

jejejej Thanks but I've already put a 65mm mustang throttle body (cable) and the response is like no other. The negative feed is that the air conditioner is not working baaaaa!!! I've got to connect the old throttle body (the stock one) to put the A/C working but at high RPM's don't work at all either.

The problem is the maximum airflow for TPS table. With a larger throttle body you will exceed some of those numbers. The stock ECU puts an end to that fun.
