hi guys well this is my problem . i just install the ecu stage 1 . and the problem is after 10 pounds the engine start multiple missfire below 10 pounds no problem. engine light came on and code is multiple missfire in all cylinders . mi car is a 2000 audi a4 atw . thanks

 

Where did u get the tune? Take it there ASAP. And have them see wassup with it.

 

Sounds like you didn't gap the plugs down to .028" (stock is .032"). Did you upgrade the DV also?

 

agreed spark is not enough or not enough or too much fuel! pull the plugs after u run it see what they look like? stink like gas or built up carbon?

 

Which spark plugs you recomend to install on the car ?

 

You're fine with stock plugs. Get a new set and gap them properly.

 

Devil is most likely right on. But its not uncommon for coils to crap out right after chipping for the first time.

 

Thanks for the help it was the gap on the plugs it was way open i set up at .28 now is a diferent car .
