can you post the # of results .... but if is i believe is 696 the limit but is is around 80 above this is what it could be egr or o2 sensors ... also how hot it's running .... in my case i need a tune before i can put a 180 t-stat cause my fan was turning on way too late ... and was causing my readings of 744 Nox ....
 
NOX were like 850 @ 15mph and 902 @ 25mph and that was in second gear...I know the smog guy so he tries to hook me up but he couldnt get it to pass...car doesnt seem to run hot but I dont know where the cylinder temp is at...
 
just bring it up in here to oakland ..... i know you know ....;)... it passes

NICE! I could get it to pass by doing a few things, but I want to fix the problem ya know?

I'm going to call Dave today and see where I go next...thanks guys!

I was just talking to Jmat about this recently .. get a group together and just pay for Dave to fly out here and dyno tune our cars. :D

Becerra - I might have to take you up on that smog one of these days if you know somebody.

IDK how many tunes would be necessary to make it cost effective .. it wouldnt be cheap. I wouldnt mind a custom tune, Jmat will need one when he puts on his bigger injectors and MAF .. was hoping Paul would get his car together and most likely would need one also. It was just a thought.
