PCM Flash for "E" calibration PCMs
Hi all,
I could have posted this to the last PCM reflash thread, but thought it important enough to highlight separately. For more info on current flash levels, refer to this thread:
https://www.rx8club.com/showthread.p...threadid=21879
Just got back from the dealer (Mazda Aspley) - had a 10K service. Mentioned that I thought that idle was a bit rough - may be misfiring. The service manager mentioned that there was an update available for some cars and they would check. (My car is a July 03 Build with an original PCM calibration of "E".)
They did apply an update. When I collected the car the service manager mentioned that they had also applied this update to another car at its 20K service and it was about the same age as mine and the owner had mentioned that he got more power from 3000-5000 RPM.
So on the drive home I gave it a bit of a run to see if I could notice any difference. The tone of the engine is definitely different below 5000RPM and it does seem to have a little more pull at low RPMs. Acceleration seems to be more linear across the rev range. Prior to the flash there was a real jump around 5000RPM where the car became a "little more wild" in its performance. Also seemed to start a little quicker (but have only tried this once - will report more info after a few days).
Now I must hedge all of this information below with the fact that roads are wet today so couldn't really try her out... and I haven't noticed a huge difference in the coightometer.
When I got home tried the pump the brake pedal 20 times in 8 seconds trick - oil gauge responded with a sweep to half way and back again.
Don't know what the exact calibration is - couldn't extract that out of the dealer. Hymee - if you want to read the OBD port - PM me.
Cheers
sco
Edit: No evidence of re-flash in the form of a sticker - either in the engine bay, on the bonnet or on the PCM

Sco,
I had mine done a month or so back. It is definitely stronger in the 3,000 to 5,500 rev range. I am not sure whether it keeps going as well from 7,000 up but these things are so subjective.
The old butt dyno is not the most accurate measuring tool!

Smoothy, does yours respond to the flea scratch brake pedal test?
Maybe there is a further update that has been released here in Australia?
Curiouser & curiouser!
What about other people here. Do they get the oil sweep thing happening or not?

Hymee... could be a "G" flash - I don't think the factory "F" flash responds to the flea scratch on the brake pedal reset.
I need you to introduce me to your mate at Aspley - can't seem to extract much info out of Aldo. :p

Sco, excellent info.
My car is a July '03 build and was flashed from "D" to "E" last week during the 10k service.
It would be interesting to confirm your flash level - keep us informed if ya do.
Cheers,
Pappy

Could you do the brake pedal test to see what happens? This could give us some info about how recent this latest update is.

Tried the brake pedal test but didn't get the oil pressure needle sweep. I'm fairly sure I have the "E" calibration.

Went for a drive down to the Gold Coast today. Some more observations:
- Car is running well. Does seem to have more power around 3000 - seems to maintain its speed up a hill at or just under 3000 better - less throttle required.
- Starts quicker - starts instantly - previously it would take about 2 to 3 times longer.
- Seems a little quieter between 3000 to 5000
One other thing I'm not sure about - tacho seems a little different - seems to be a little lower at times for the speed than prior to the flash - especially at 60km/h - no empirical evidence here... so it could just be my imagination.

Update. Hymee has confirmed "G" flash. Details on this thread:
https://www.rx8club.com/showthread.p...threadid=21879
Hymee - maybe we should lock this thread and continue discussion on the above thread.
