Thanks for the info. I was suspicious of the claim. Another benefit of this forum.

polak - as stated above it can be done but you have to wipe the wds and then reload up to the level you want to stop at. but this affects what they can do for other MZ cars which may have "good" updates at higher wds levels that need to be done.

If downgrading is difficult, why not just re-release the code of the original M flash as a new release. Call it "N", and move forward?

To quote Jean-luc Picard, "There are plenty of letters left in the alphabet".

Or. . . if everything is right in the current M but the CEL comes on once and a while the software could just ignore it since that is what we are supposed to do. That way it would be ignoring only the faulty code where as we might be ignoring a real problem.

it doesnt work like that. each new release contains the previous plus the new. kinda like overwriting when saving a game. in order to go back you have to start over and work your way back up.

Ok guys...I am so very confused about the new flashes. I took my car into the dealer yesterday because the CEL was on for the fourth time in two weeks...but this time it had stayed on for a full week without going off. The car had been idling rough, starting hard (almost flooded it so I finally took it in...and I do not EVER shut it off cold), and completely lost power on a cold, not freezing, day in second gear at 4000 rpms. The dealer told me the code for the CEL said something about the gas fumes not being released? (ok, really I have no clue and think it was a bunch of BS...code was P0456). Well anyway, their solution was of course to reflash with the newest flash (after I talked to the service tech and asked him to make absolutely sure that it was not the flash that had been halted). It says that they reflashed per bulletin 01-024/03. Now...with that information, did I get the screwy reflash that they weren't supposed to use yet? I really don't want to have to take the car back in for service again in the next week or so. Just for the record though, car ran great on the drive home from the dealership...smooth idle, easy starts, no loss of power, etc.

Tbone: I couldn't have said it better myself! Two more times into the shop for a no start and I'll be talking to a lawyer about the lemon law. I love the car also, but I can't live with these neverending problems.

P0456....small evap system leak. Emission system issue. Different code to the one causing the problems. Could be a loose hose clip, could also be the PCM or flash. Whatever, it's a different fault. Not a major issue, though.

As Gomez stated the code the PCM stored was for a EVAP system code..

NO EVAP CODES will cause a drivability issue. The system is different than most cars as it will test after the car is shut off. It works like this..

The latest flash will flag a P0126 code on HP cars..

Looks like they took you back to the "K" flash based on the 01-024/03 TSB flash file nomenclature. I suppose that the original [read good] "M" flash would have been preferrable, but at least it isn't the faulty "M" flash. Be thankful that they did what they did, because it is apparently quite a hassle for them to set up their WDS to do that.

If and when Mazda gets the newer flash, whatever they call it, straightened out, it probably would be a good idea to have it re-flashed. That is, after lurking here for awhile to make sure it isn't another bad flash.

zoom44

no they didn't. they used that TSB to justify flashing the due to the code they found. the TSB will say "if problem Z found flash to at least level x or newer with a WDS at level x or higher. so they gave her whatever the lastest flash they had in their WDS.

2 problems from my view-
a.she was already at a higher level than what was required to stop the false evap test failure codes. so they should have checked for furthur reasons for the test failure code.

b. she specifically asked them to make sure that the flash they were going to use was not a problem. if they had called the tech line to verify- LIKE THE CUSTOMER REQUESTED- they would have been told NOT to do the flash.

my conclusion- whatever caused the code could very well still be an issue AND she could very well have buggy code

with all this talk about "flash" this and "flash" that, I'm starting to hear queen in my head..."Flash....ah ahhhhhh.....he saved every one of us!"..........."Flash...!....." :D

"WHAT do you mean flash gordon approaching? open FIRE! all weapons. dispatch war rocket agents to bring back his BODY!" ahhh Flash....":D

I have just ONE question - what do you do if you got the latest flash that may still be buggy. Do you take your car in so they can send you ECU off or do you have to wait for a CEL?

snap-on

The "buggy" flash may or may not set a CEL on your car.

A quick recall from some PM's (along with other input) tells me this effects a small percentage of HP cars. I have yet to see a auto tranny car set the CEL for the P0126

zoom44

the part numbers you posted are for the original M flash which was fine. however i cant tell from what you posted if that is what he gave you or if that is just what printed since they printed the info about MSP04. he could have "ghosted" his wds back to that level but i would be suprised to hear that he did. did they list any part numbers seperatly from that line. also what is your cars build date? also did you have your car flashed previously?

RX4+30Years=RX8

Here is exactly what they wrote up on the repair order about the Code;

9330 F0008XDX F0502XRX 0.7 PO456 EVAP LEAK VERY SMALL LEAK RAN EVAP TEST FAILED PERFORMED SMOKE TEST AND THE SYSTEM PASSED. TESTED THE FILLER CAP IT WAS LEAKING REPLACED CAP

What else would the PO456 be caused by?

I have to take it back first thing in the morning so they can have one more crack at fixing the gas mileage issue.

Ok I just got back from my appointment with Mazda. I had requested a meeting with the DCSM, all I got was the service manager. They checked the PCM and found a new flash.

I already had the "M" flash as per MSP04 when they flashed it back in May.

Now don't get excited, they called it 34.9 which we all know is the WDS revision level. When I pressured them about the file name that they downloaded to the PCM all they could tell me was that it is the latest for the manual tranny and again told me it was 34.9.

So what flash revision later them MSP04 is in the WDS 34.9?

Just driving home, I could feel a big difference in the engine response. Not necessarily more hp, but I only had to give it half throttle to get the same accelleration I got before at almost WOT. That could translate into better mileage, but I'll wait to see some numbers I can average over the next few tank fulls.:D

I am still curious about the flash level in 34.9 that is later than the "M" I had previously.

Mr M

My totally unqualified, unfounded and unreliable opinion is this (I have to say that as an 'official' disclaimer):

If you have driveability problems and/or unexplained MIL illumination after having your vehicle PCM flashed to the latest level, ask your dealer to return it to the last 'reliable' flash level. How this can be achieved is going to be between you, the dealer, and MNAO, but it is a reasonable request. Those of you who have tried this to no avail, try again (but harder!).

Good luck.

For what its worth, the dealer just flashed my car to the latest, under the MSP04 bulletin or whatever...and I'm pretty sure I was at the M flash already. However, so far no CEL or anything else, and power is either the same or better (my butt dyno says I'm getting better power up top but I consider it very suspect).

Just got flashed yesterday (was already M due to rough idle and extremely rich). Told service tech not to reflash but he said they got another version and it was fixed (I never believe what they tell me). Haven't had a CEL yet but I did notice a bit of lag in the upper range but I haven't given it any more runs up top to see if she was just being finicky.

davefzr

Try driving hard in 3rd gear and shift into 4th just as hard. I am getting a CEL when I do that. Never got it before.

I'll give that a try tonight or tomorrow morning and let you know (via this thread of course).
