I have a new 8 with the M flash, and wwhile the tach idle's smooth, I get a slightly vibration through the cabin every few seconds will sitting at a stop and the car is idling.

I was wondering if the Zoomer box helped with this, did it smooth thing out for you guys?

 

made mine worse.

my idle stayed the same, it wasn't ever super smooth but can't complain.

 

Ditto for me.

 

Ditto ditto

 

Yeah, usually it's smooth. Then at times, it's not very. Haven't correlated the "when's" or the "why's" yet myself. I really don't drive it enough lately to have constructed a pattern.

 

i think the "idle issue" is the result of the reverse firing order at idle.

 

Zoom44, can you explain what you are referring to?

My idle is worse also... definitely stutters more at idle and without CZ mod it idled much smoother. I actually tested the M-Flash out before CZ mod and there are differences at idle. However all the other benefits out weigh that little annoyance.

Besides... an RX8 at idle is classified as abuse i think!! Anything below 60mph is abuse isnt it?

 

While sitting still my car idels verry rough to the point where my check engine light came on. I took it to the Dealership and they told me one spark plug had a miss fire. It only happend onec. Can you go into the maps and fix this?

 

Yep, my idle is worse, stays worse up through to ~4k RPM.

 

Mine is worse with the CZ and I actually pulled mine out today. It’s too hot out here and I’m worried about the coils.

 

mine was terrible with CZ and K. and K had a good idle. I have M now and no CZ and its rough, but not as bad as CZ & K.
