oh, i have 15,700kms on the clock

the car starts easier and sounds a little different for the initial start up.

smoother running and smoother idle.

powerwise, i dont know and dont think i should say based on butt dyno, but i do know its a hella lot faster than that mazda 2 courtisy car!

hi kas

which dealer was it in melbourne?

did the oil pressure guage react to the 20 brake pedal presses in under 8seconds like sco and hymee's?

thanks

Apparently Brighton Mazda are aware and are performing the re-flash.

mktchin

thanks for the info.

i'll ring essendon mazda tomorrow to see if they know anything.

I went for a drive and checked the AFR's last night. They are better, particularly up to 4,000 RPM. Pretty much right on the money at around the 13:1 mark. After that she looks to go a bit rich, mainly in the 12's and dipping into the 11's. "A bit rich" is according to popular wisdom. Perhaps time will tell if the Renesis does like it "a bit rich". So far, tuning efforts (from what I have read) has been aiming at the low 13:1 zone.

I did 6 accelleration runs (2nd gear, 40 km/h - 105 km/h, A/C Off, DSC/TC Off) with this new "G" flash. Temp was between 19 and 21 degrees.

I compared these with the 6 most recent runs I did with the "E" flash.



Note: The fuel/ignition controller was "OFF" in all these tests. I have not made any adjustments for the differeing weights of the vehicle between when I last tested with the E flash, and the G flash last night.

Draw your own conclusions.

Here is the summary results of the actual time measured for each test (40km/h to 105km/h):

E Flash - Tested 21-APR-2004
5.54 s
5.54 s
5.61 s
5.62 s
5.62 s
5.62 s

G Flash - Tested 10-MAY-2004
5.36 s
5.22 s
5.22 s
5.55 s
5.47 s
5.39 s

All in chronological order. The plots above are the averages each of the six runs.

Cheers,
Hymee.

BTW - For those that might ask the next question... I did a couple of little tests with the fuel controller "ON" to check AFR. There OK, but not ideal. I did 3 runs with a best time of 5.19 and a worst of 5.23.

Great data, Hymee.

I'm sorry, I can't help myself (and am surprised that no-one has beaten me to it), but.....


...... at last with this new calibration, we have found the elusive G spot .....
:p :p :p :D

rx8 - smooth!

Hymee,

Awesome info mate. It looks like it is going to be worth the effort to get this latest flash installed. .25 of a second is a significant difference.

Hymee, looks like the cheapest 8kw available for the 8! At least on a Hymee catback equipped vehicle....

I think I am going to get lynched by all those people who paid good money for a fuel controller, and all those who have invested time and money in developing one! I still think they have a place though, as reported by my last little tid-bit.

It is harder to do back-to-back comparisons with a re-flash, because you cant switch from one to the other and re-check the figures like you can do with the piggy back.

The only problem I have with the figures is they are on different days, and I can't remember how much fuel was in the car on the earlier 6 runs. It was close to empty last night.

Cheers,
Hymee.

PS - Maybe I should have just plotted the worst v's the best and found anouther 2kW - Wow a total of 10!!

timbo

Yeah, I agree Gomez. I reckon it is the combination of the G flash & the Hymee catback

mktchin

i just called essendon mazda. the rx-8 service manager said that there was an update for the WDS for the ecu. he said that the ecu updates are checked each time the car is serviced. if there is a new version on the WDS, the acr is updated. i'll just bring the car in for the 10K service in a month or so and get the update then.

Great news... it does no harm as it is free to upgrade.

Thanks for the stats Hymee... very interesting.

Got 13.8L/100 on my last tank (5/6ths driven on G flash). I use BP Ultimate.

Mostly non-grandpa city driving with a redline or three thrown in for good measure. About 1/3 was highway driving probably averaging around 3600RPM.

First real test will be first full tank of city driving where I rarely get below 15L/100

kimba2

has anyone got their car reflashed at oldmac mazda springwood

Pappy

Hymee - fantastic data!

Rang John Newell Mazda and they are checking if they have the updated "G" calibration.

If anyone in Sydney knows of any dealer who has the "G" - please let me know.

Cheers,

Pappy.

I purchased my car from oldmac springwood , however sorry to say that they seem to know jack **** about updates and they seldom bother to get back to me on any queries i may have .

Spoke to a neil in service who promised to get back to me 48 hours later i am still waiting .(**** service imo)

Goldcoast MAZDA has the calibration updates so i have booked in to get my updates on the WDS .

Small dealers dont seem to care were you get your car serviced oldmac has been a huge dissapointment for me .

Sales at mazda golcoast missed outon the sale of my car for being innitially rude to me but they have won me in the service department .

The only person that knows whats going on at springwood is Troy in spare parts the rest are totally uninformed .

cheers

Greetings All,

Stupid question time - is the latest flash available suitable for the auto as well ? Ours is going in for the 10,000 service in 2 weeks so it would be good to know if it is suitable and if McGrath Sutherland knows anything about it ! I'm a bit clueless with these kinds of things and there seems to be a lot of misinformation at the dealer level - what a surprise...

for what it is worth no matter how we drive our auto it stays between 11.2 and 11.7 l/100km - and yes I know it can't go as hard as the manual before you all say it :-)

Regards
Jeffneil

Jeffneil,

It actually goes harder than the manual before it runs out of puff!

I suspect the actual calibration for the 4 port (i.e. auto) is different to the 6 port (i.e manual). I don't know what the exact version numbering regime is. It might indeed be a "G", but a G of a different series.

Our Auto friends could help start finding out by looking under the PCM cover and getting the number of the sticker under there. Something like N6J...........E. Or if you have a scan tool. Or if you just rock up the the WDS and get them to check.

Cheers,
Hymee.

Gomez

Mate, I reckon it should be O.K for the auto....If it isn't, there may an equivalent "auto" flash on the same software release...

Regards, Gomez.

Guys, I'm on holidays (without my RX8 unfortunately ) on the Gold Coast at the moment. I got my ex (Mazda Dealer) to check with the rotary techs at her work, and for those that live around here, Southcoast Automotive (Tweed Heads) has the latest update. I'm not sure if this is the same place L&L was talking about. I'm not all that familiar with the area!

Cheers,

South coast Automotive have got the latest upgrades on the ecu however they will charge you a premium for upgrading your car .

Ross the service guy was reosanably informative , but they take the view that any computer upgrade on your ecu does not neccesarally have to automatically put on your car unless you have a problem with it .

They also believe that you should be charged for the privilidge of getting the latest software .

I believe that MAZDA SHOULD AT LEAST NOTIFY THE EARLIE ADAPTEES OF THE RX8 AND GIVE THEM THE OPTION OF UPGRADING THE ECU , AND THE OPTION OF WHETHER THEY WANT IT .

I certainly will wait 12 to 24 months before and if i buy into another rotary as the early birds who buy the 1st release of any model truly get the short end of the deal .

NOT HAPPY JAN
cheers

when i went for my service they looked at my VIN and then rang somebody and said "yeap we have another one" and then booked it in.

NT Rotor Head

L+L,

I certainly agree with you on the availability of PCM updates for any car. If the manufacturer sees fit to make one in the first place then surely there must be an issue that needs resolving and all should be entitled to the 'fix'. If Mazda arent willing to invest a few dollars in contacting the owners of their product, I think at the very least they could put a 'Support' section on their web site similar to computer parts manufacturers, list their vehicles and have FAQ's, Updates, Recall info, and other issues for the interested owner to check on. It could be then up to the owner to take the vehicle in for the update. (Safety recalls excluded of course).

Another thing. I really disagree with the dealers giving people a hard time about updating. If an update is there then we should be able to go in and ask for it without having to give a reason. The fact that an update is available is reason enough if you ask me!

Anyway, I'll see how I go up in Darwin at Kerry's Mazda. As usual I think it will come down to how I 'go about asking for the update'. It seems you need to be on the good side of the service guys to get anywhere.

I am taking my car to the dealer tomorrow for upgrade flash to the ecu. My VIN is very close to Taka's (SEPT build) and I am not sure what code I currently have. I will keep you posted after tomorrows events.
