Hi guys :)

 

My NA-T project is complete and I have created a monster :) got ALL parts from Paul Whiffin incl map. I'm driving the same setup as the test car they used. It pulls perfect and everything works suburb :D

 

But, when I'm driving quiet and rpm's are between 1300-2900 it is rumbling a little. When I push the throttle it go away again.

 

One off my friends tell it is the map but I want to hear if any of you guys have tried the same? :cool:

Update: dizzy is set at 10 degrees as I was told. The shaking and rumbling is still there :blink:

 

Will mount PLX AFR in a couple of days.

 

A mapper here in Denmark suggest it could be to much gasoline or to less?

 

Any of you who know the guy that make this map? :) then I can call him and asked if I have done all correctly :D

Hi mate

 

I have tried a lot of things, latest was the spark plug cables.

 

Then I reset the whole car by unplugged the batteri for 60min. I lose the TP sensor and adjust it with the engine running. Set it to 800rpm and my afr showed 14,6-15 on idle and the problem was gone :)

 

I don't know why it does that?
