got my updated today from the l flash. I went from h all the way down. the ride is so much smoother. i think the power is more evenly distributed. while the older version felt more like it was in chunks this one is through the whole gear.

To chime in here. I just received the M flash update, not sure what my previous flash was (build date 1/04), and I am very happy. It has much smoother power delivery, shifting and idling. My MPG was averaging 12.5 to 16.5 (heavy footed). I record every fill up and will report new MPG after flash.

Some Dealers don't put a sticker on the car..
Maybe the invoice will tell.

I looks like you can't get the flash unless you need some kind of service, as well. I'm not scheduled for an oil change for another few thousand miles, but I'd like to get the flash sooner rather than later. Is the only way to get it to make up a story? They won't flash the car if you bring it in only for that? That's not right... maybe if I throw a tantrum they'll give me the flash

Well, I got the M Flash on my AT last Friday, started a new tank of 89 octane on Sunday and in mixed city/hiway using my AC sometimes I just got 17.7 mpg. Before the flash I was lucky to get 16.0 mpg in similar driving. And the acceleration is definitely smoother in full auto mode. The service tech said that it should even improve more over time. Very interesting. Happy camper here!

Got the M flash on Tuesday. There is a noticable difference in the performance of the car. Seems like more low end torque .... engine revs quicker and smoother. Just filled up today.
We'll see how the mileage turns out.
Bigger grin than usual after picking it up. :D

ok.. I tore apart the engine compartment. I found the ecu. no stickers that say anytihng about the flash version.
the door jamb sticker says nothing about it.. and the window sticker say nothing..
But i guess ill take it in however, I am concerned about the recalls and the nav updates. My 8 needs the dapener recall cause i can find no stickers saying it happened. I need the heat shield mod, the oil pan mod and the Nav upgrade. Is my dealer going to freak out when i tell him all this .. ?

OK, I tried the "honest" approach - I didn't claim any CEL problems, hard starting or anything. I just said that I felt like there was hesitation in the throttle response and shifting was jerky - both of which are true. For my honesty I got lies from the Rosenthal Vienna service dept.: it already has the most current callibration, it has the "N" flash (no ****, they realy said that), the TSB does not say that it is required for all RX-8's built before 3/12/04, etc. So much for honesty!

In any event: what's that cr@% about 'N' calibration? Wouldn't it be easier if they would USE their own website for reference, for Ahura's sake!

I switched off the AC that I was running at the time and it really didn't make a difference. I tapped on the gas and it smoothed back out.
Is this the "rough idle" that many are referring to and experiencing? It appears that many of you are getting this cleared up with the new flash - from what I'm reading.......

When I first come to a stop light and the engine idles down, after idling smoothly for about 30 seconds or so it starts getting rough.....shaking the crap out of the gear shift and making the whole car vibrate slightly. If I gas it a little, it smooths out.....but then is rough again after 20-30 seconds. Sometimes it will get rough.....then smooth out on its own without tapping the accelerator. This all happens with the A/C compressor not running too. I could accept that idle pattern a little better if the A/C was cycling on and off, but this was with the heat on and air directed at dash vents and floor. The compressor should not be cycling.
I guess I should try new plugs..??

Not sure if all dealerships use a standard service form, but mine actually says "FOUND UPDATE FOR PCM WITH NEW # N3H6 18881 -M" on the service work order form. I assume that the "-M" at the end means it is the 'M' flash.
