Is N3Z2-18-881M the N-Flash (manual)? I couldn't find anything with the subject heading using search. For guys that have bothered... how does it "feel?"

 

Did you eventually mean N3Z2-18-881N?

I think that's the anti-flood flash and I guess the one I got in December. They keep updating that bulletin, so I lost track of the versions.

To me it "feels"

- slightly torquier
- definately rougher when the car is idling
- slightly mileage improving
- fumier (as if the exhaust gases contain some unburned fuel now)

Edit: N3Z1 (AT) -> N3Z2 (MT), Reactionary is correct.

 

I think you wrote the wrong number. My invoice says N3Z2-1881-N. Mine doesn't feel any different from the previous M. Seems like L was getting me slightly better gas mileage but not sure.

 

TSB with N-flash P/N. Look at the bottom of page 4/5: http://www.finishlineperformance.com.../01-008-05.pdf

 

Guys, regarding the new PCM recalibration number I stand corrected. It does not seem like a lot of people have jumped on this bandwagon to reflash to the newer N-flash. I was hoping for more positive responses from California cars to justify/make the trip to do the reflash...

 

My idle seems a little smoother, but I now have a sulfur smell from the exhaust.
