Series II ECU Tuning

As I mentioned in an earlier post, I did recover from a write error with ME which resulted in a car that would not start or even return ID and VIN number to ME.
Now, it could be that there is some point in the flashing process where if it dies it cannot be recovered, and I was lucky enough not to have the write error at that time, or it could be that ME has already got around, or is not affected by the issue veratuner is seeing.

So sounds like what VT is doing is spending some more time on precautions.

From what I understand from my brief conversation with VT on the topic, the last step of their testing is deliberate brick and recovery. They set up a bench test and did every "dont-do" to try and brick the ECU (ie unplug, power down, interrupt, etc).
So sounds like what VT is doing is spending some more time on precautions.

Anyone know what the stock injectors are rated for with the S2? I saw on another thread that they were listed at 390cc and 480cc by mazda but is that accurate? I'm assuming that's flow at 3bar too. If that's true, then the S2 has a total flow of 1740 compared to the S1 which has 2300 @ 3bar (assuming 290/380/480). Does the S2 have a higher fuel pressure than the S1?
Anyway, for the stock map in mazdaedit on the R3 the injector scaling is set to:

Actually I found this thread which says 450cc primary and 570cc secondary which makes a lot more sense and also lines up better with the stock injector scaling.
Just trying to figure out what cc secondary injectors to use with a FI setup. Have stock primaries and ID2000 secondaries and it's overkill. When the secondaries come on under partial load it's way too rich. We can go WOT and punch through it and they behave fine after but it's just when they initially turn on is the problem. Will try to swap them for ID1300's...

BTW : your first post was correct with the sizes

Mep was running on a desktop (same PC that runs the dynojet software) and was not attached to a UPS.
Last I heard it is now surge protected and on a UPS.

If I run the 480's in the primaries and 1000's in the secondaries that'll give me 2960cc, will that be enough to not run the injectors at more than 80% duty cycle at WOT?

The S1 did however come with a lot more fueling , that was unnecessary for NA , hence why they changed it ...................
Does that answer your question ?

Unless I'm seriously misinformed ,neither the S1 nor the S2 came with forced induction .
The S1 did however come with a lot more fueling , that was unnecessary for NA , hence why they changed it ...................
I run less injector capacity than that making 350 whp . If you think you will make more than that you are being seriously optimistic. Plus : the bigger you go the worse the transition will be - as you have already found out .

Well decided to go with the stock secondaries in the primary spot and 1300's in the secondary spots and it seemed to do the trick. Now if Mazdaedit could stop crashing all the time some progress could be made...

Well one crash recently soft-bricked the ECU which had to be fixed by a visit to the dealer... won't go into more details yet but just be careful.

You realize that by writing that you make me want to know the details even more 
Any idea what prevented ME from being able to reflash the ecu?
Did you get in touch with epifan and let him know?
How did you explain it to the dealer?
I feel the need to repost this. I was able to recover from a bad flash using this process and have not had an issue since as long as I have followed it:

Haha, well I just tried my first flash, and got a write error 
Tried to upload the stock rom, no go. Tried to start the car, no go....
After some contemplation I managed to find the right combination to make it work:
1. Make sure the ignition is off
2. Unplug the openport from the usb port and make sure mazdaEdit is not running.
3. Plug the openport into the obd port. (no need to unplug, replug if it is already plugged in)
4. Turn ignition on
5. Plug in the openport to the usb port
6. Start mazdaEdit, start the flash utility (F11)
7. Hit the read information about ECU icon (F3)
8. Open the ECU rom image using the file open icon
9. Hit the write icon (F9)
10. Don't move or touch anything while it uploads the data.
With my part-written flash, step 7 was not able to read any information from the ecu, but I was still able to write the data successfully.
I'm sure there are other combinations that work, but there are also some that don't!

Well, I got tired of waiting for VersaTuner, if that's even still in the works, so I just ordered my OpenPort and will be ordering ME as soon as that gets here.
Spark dwell setting was mentioned in post #779. Based on the table presented in the coil dwell settings thread, it looks like the table cells correspond to dwell time in 25,600ths of a second. Is this the case, are those numbers reasonable, and has dwell adjustment been done using ME?
I'd appreciate any advice you can offer. I find that the engine sounds somehow wrong, kind of weak, above 8000 RPM or so with the BHR ignition kit, and I would like to sort dwell times out before looking for another problem.

While I was gone they ran into another problem. We are getting an error now (7FB110 Invalid Card Response) from ME and it basically locks us out from doing anything. Epifan says that this is because we flashed the ECU more than 100 times with a non-fixed kernel version. He says its because we're using an older version of ME and the version as of Feb 2013 has fixed kernel version flashing but we only started using ME in July... anyway he says we have to use a Piasini Master suite tool to flash a file that he'll provide to fix it. So yea... have to order one and wait till it arrives... thoroughly pissed off at the moment.

When the ECU bricked it was during a normal flash write that we've done so many times. ME crashed during the write and we thought just to re-open ME and flash again as it's happened before but this time it wouldn't detect the ECU at all. Car wouldn't start, couldn't read the ECU with anything. Tried for days and just decided to get the dealership to flash it which fixed it.

He suggested that but I ended up buying a second hand ECU .

Hmmm - not good .
