Readings pre-"M"

Mz uses "open" time to judge injector pulse width rating.

At idle the Rx8 seems to be @ 1.5-2 milliseconds "IPW"

Full throttle in the bay is @ 10.0-10.2 milliseconds "IPW"

Cold start...38.98 milliseconds.

The same IPW was recorded until the car flooded (6 tries)


After the flash to "M" (the same car was used for testing)

1. 48.5 milliseconds
2. 42.0
3. 40.0
4. 40.0
5. 31.0
6. 30.0
7. 10.5
8. 4.0
9. 4.0
10. 4.0.

They couldn't get it to flood!!

 

Magnificent!

thanks for the info snap-on

 

Good info snap-on! In my receipt, they indicated they tried flooding my 8 six times but never succeeded. That's good! I wonder if others here have that on this receipt?

 

Woh.

Still, what was Mazda thinking?

 

Thats good?

I'm sure your spark plugs were less than clean after that.

 

I have yet to flood mine either. I have the "L" currently, but didn't have any problems before I got it either.

Still tho, enough people have had problems that this is worth noting.

 

wheres the TSB on the heat shiled for under the center cup holders ? I saw it once last week now i cant find it

need it for monday .

Snap-On, Thanks for the info!

 

snap-on ... Thanks for all the on-line support, much appreciated!

I just wanted to report my upgrade to "M" experience. I had scheduled my first oil change (2000@4Months) and told them I also wanted the PCM upgrade to the latest rev.

On arrival I faced this strange hem and hawing about how we're really not suppose to flash on request, we really should have a defined service condition, a TSB is not a recall and doesn't really apply to your vehicle .... but I'll do it this time. It'll cost you $85 in the future if you want this done again, unless a define service condition warrants it.

I had the printed TSB, but withheld it since he relented to do it on his own -- but what a crock.

I mentioned that all the TSB's were posted on the net and he seemed quite "disturbed".

They did the oil change and the upgrade, but I'll likely be in search of a more cooperative service department.

Cheers,
Oranje

 

Oranje..

My pleasure...and I apologize for the treatment you recieved..

If I may interject maybe I can put some light on this subject..

Page one of the "modified" TSB is a major departure form Mz's policy in the past.. All previous updates were supposed to be authorized via the "tech line". Even the TSB talks in contridictory terms. Page one tells the guys to update every car and page 11 tells them the problem has to be verified.

Until this month when the Dealer ran your "VIN" it told him of any "recall's" and "SSP" work they could perform with no fear of being accused of campaigning repairs on the service drive.

Mz has released a new form of repair called a "MSP" they are using to update all 04 Mazda6 4 cylinders for a O2 sensor issue.

Until they issue this for the reflash on the Rx8 some dealers will continue to look at this with some opposition.

Feel free to PM me if there are any questions

invaluable info snap-on

 

Well I finally got a whole tank used while driving very conservatively (translate that to boring) as compared to my normal WOT drive for the fun methods after the M flash.

Before the M flash I was getting 12.9-13.2 mpg no matter how I drove. After the M flash;

Drive for the fun of it (WOT all the time) - 17.9 mpg

Conservative (never WOT, rarely over 5K rpm) - 18.9 mpg

Both of these are daily driving to and from work with 70% of that driving being in stop and go rush hour traffic. 37 miles one way.

I am certain that non-rush hour driving on the highway would yield over 20 mpg.

So with premium 93 octane costing almost $2 a gallon right now and confronted with there being a 1 mile per gallon difference between fun and boring driving, I think I'll can pay the extra and opt for FUN.

REV-IT-UP!

 

I feel lucky I have the Dealer I have. Last time I was in they asked me if I also wanted the latest flash, which I believe was "L" The work order just says reflash the ECU.

I do have a question though, at about 9000 miles, the personality of the engine changed. It seemed to have a lot more performance and also got slightly louder at high rev's. Has anyone else experienced this? I am curious if it is an ECU self correction, Perhaps something with the ECU having registerd detonation in the past and retarded the timing, then after not seeing detonation in a while, advancing the timing again?

 

Guys-as weather in SoCal has warmed I have noted some fluctuation in air temp of AC in max cold. For several seconds to 15 seconds air from vents warms somewhat then will get cold again. According to TSB the VINs of cars affected are about 10 from my cars VIN. Could the temp fluctuation be normal for RX8 as long is not actually warm air coming out? Maybe I do not need to worry about it?

What do you think?

Thanks,

Bob

 

This whole A/C issue is so hard to determine due to the human factor. How something feels to one person is completely different to another. The A/C prior to the new amplifier on my car was cycling to the point that it felt like I was tuning the switch off and on..off and on... etc. The best way I can describe it is the slightly humid mild air that comes through the vents if you turn the A/C off while leaving the fan on. This is because the the cooling coil is soaking wet with condenced humidity....the second it warms up (if the compressor stays off for too long) the water re-evaporates into the ventilation system. This gives a sticky feeling mild air burst from the vents. This was happening constantly prior to the new A/C amplifier, and it was very annoying.

After the fix, my A/C did not do this. It remained a more stable temp. If I pay real close attn to it I can still feel a minor temp change. It is far less annoying, however still present. If I never had the first problem.....I would never notice the current minor cold/cool cycling.
My guess is that your car is operating normally.

 

Hey Doc..does the "mode" change by itself?

When you select "inside air" it should stay there and not defalt back to outside air. Once the system is off of recirculate hot air is only passing over the evaporator once.

 

Thanks for information and feedback! I will pay attention to what was suggested and will just enjoy the car.

Thank You,

Bob

 

hey this might be a little off topic but.....my seat warmers don't really heat up much at all, especially the passenger side. Has anyone else experienced this problem?

Off topic as there's no TSB for it. Try searching for "seat AND warmer" - you'll find some threads on the subject.

Off topic, but mine don't heat up at all. They did once on a cold day when I first bought it, but it has been warm-hot outside ever since so it may be tied to the outside temperature.

See previous reply.

 

The Leather Seats are the reason

Mine to.. I was warned by the Dealer ... THe Leather holds in more of the heat away from your butt.. its skin afterall

but wtf do i care its 70 deg all the time here :P

 

Where are these TSBs coming from? I mean, if I print it out and show it to a service guy, how does he know it's official if I got it off the Internet. I called MNAO to ask my dealer to reflash my car, but they started questioning about the validity of the TSBs I got off the net and I didn't know how to argue my point. Where are these TSBs coming from? And how come the lady I talked to at MNAO said these official TSBs aren't released to the public?
