Hello,

My 1999 A4 V6 is only showing 76% at WOT. The reading is from an OBDII monitor while I am pushing on the throttle with my foot.

This may actually be correct but I am looking for some opinions.

Thanks,
Chris

 

could this maybe be why ur nitrous isnt performing as well??

 

It is difficult to say because I am not sure about the dynamics of the TPS % compared to the actual Throttle Body position. That is #1.

#2 is that I am not sure about how the variable INTAKE MANIFOLD plenum may effect nitrous. Since this in not a direct injection, the nitrous must pass through the TB, the IM, down to the cylinder chamber.

I am really hoping someone can tell me about the OBDII % reading at FULL THROTTLE before we begin pulling the intake manifold off the damn car.

Let me know,
Chris

 

post in the nitrous/turbo forum... you will prob get more knowledgable responses there...ive never had any experience with an OBDII on audis.

 

The tps should read about 90% at full throttle.

 

Thanks for the responses.

The throttle cable is fine... I took apart the underdash and verified that the pedal was pulling on the cable the correct ammount. I got an extra 1% which is nothing worth metioning.

Are there any other adjustments that anyone may suggest. I really don't want to dig to get to the TPS unecessarily.

Are you positive it should be 90% on the V6 30V?

What should idle be? Mine is set at approximatly 3%.

 

Every audi ive seen is usually around 90 for wot. Idle is usually anywhere between 3 and 6.

 

this is the problem when modding you have to take all things into account exhaust/fuel feed & pressure/engine enhancements/lunch times/tyres/wheel sizes/air intakes
