Ok let me jump in on this issue. I went down to my dealer this past Sat for their Car Care Service day. I had all the fluids checked, tire pressure, etc and I also had the reflash done. According to the invoice I have in front of me, the part number they put down for the PCM reflash is N3Z1-18-881G. Not to say I'm the exception to the rule, but I did ask them if there was a flash upgrade, they said yes, and I had it done in 15 minutes. Granted this Mazda dealer is our Miata Club's sponsor, so they know me there but hey, I asked and recieved. :D


Anyone know what this reflash does exactly?

Ummm I'm going on what was printed on my invoice sheet. If the number I posted is the "new" flash but according to you it wasn't avaliable until yesterday, how can I verify what I recieved? That is the question....

Surely by now the Dealer had the 33.0...even if they simply waited for the major updates..

There is NO WAY they had the 34.2 last Saturday. It just came out last night around 7:30 est..

Call them and make sure you got the "M"....

Really you should have been at "M" before you went in unless you were a early build and had never been to the dealer since you bought the car.

Got my "M" flash today......

Hello everyone. I am pleased to announce that I go my "M" flash today. I did not know about the "M" until I started reading the posts on this forum, so I would like to thank everyone who participates on it. I think that the information that is shared on this forum is extremely helpful, especially to a new RX-8 owner such as myself. This forum helped me in my decision to purchase the RX-8, and it continues prove its worth. I love reading the post. In fact, I probably spend way too much time doing so but hey, everyone needs a hobby! Anyway, for what it's worth, thanks everybody. :D

Now everyone get back to work on that wax job, the weekend is coming, and we need to look our best

Oh, hey zoom, the "N" flash must stand for "N"evermind as Rosannadanna would say.

I had my car serviced today and they held off the M flash because the codes are being updated as of this Thursday at my dealer. Maybe this is what all the N flash buzz is about. I'll be getting mine done on Monday or Tuesday of next week.

I got flashed today, also. (Well, my car did). My 2 week old 8 had the "check engine" light come on driving home. Thought I might have been low on oil but it was ok. Took it straight to the dealer and in 30 minutes it was fixed and the Service Manager said that they did an update on it. I asked when I bought it 2 weeks ago if everything was updated and the salesman, of course, said yes. I guess it is now and it does seem to run smoother. I assume it was the ever popular "M" flash. Maybe I'll get better mileage too!!

Question

Does this new bulletin still refer to the 'M' flash? Or is there another newer flash...

I *think* it looks like the first one is the M flash and the second is the L flash:
PART NUMBER > N3H618881M (from first one)
PART NUMBER > N3Z218881L (from the second one)

That's correct. I'm going by the letter following the 1st "E" in the filenames:

FILE NAME > SW-N3H6EM000.HEX
FILE NAME > SW-N3Z2EL000.HEX

Also, these two files/part #s are for the 6 speed. The automatic has seperate files/part #s (H4 vs H6 and Z1 vs Z2).
