. Basically you d/l the full ECU table...make your changes and then upload it back (flashing). There is no "partial" flashing going on. Yeah I am sure you can do it more....heck Al has on his...but i'd rather not mess with it...i play with software for a living and the one thing I have learnt is that you never trust hardware!!
Honestly been thinking of getting another 05 ECU, copying over the flash from my current one and then just meddle with the original ECU. If it ever goes bust I plug back in the "base" ECU and rock on
.Let me know how it goes though Jeff be interesting to see what can be done with the new head.
I guess I'll actually have to get off my lazy butt and throw my PLX M300 in the car finally now, maybe even the hallman pro or profec B that are sitting on the shelf.....and I swore I wouldn't mod this thing at all, KEEP IT UNDER 300HP
Does anyone know if the logging software being developed will allows you to log wideband input on another 5v channel?

I played around with flash write failure rates awhile back and was quite surprised by my findings. A typical device will sustain about 75,000 write/erases before having some portion of the flash go bad. You will also, typically, see the flash write rates slow down as the flash is used. This is pretty normal, from what I have found, but is not an early indication of failure.
There are however some interesting things that will affect the longevity of a flash cell. Noisy power and fluctuating power while performing flash writes can seriously degrade a flash unit and cause premature failure in the device. Unlike hard drives, there is no FAT table to mark a bad cell, so that cell will continually get used, which corrupts the data. Using a network of capacitors and resistors, and one small POT I was able to get some modern USB flash devices to become inoperable after only a few hundred writes. This being the case, it is very very importent that you have a nice strong battery, that is fully charged, when you perform your flashes.
Your milage will also vary depending on the type of flash memory that is being used.

There is most certainly at least one, if not more, VE tables involved, along with a small host of other tables that the ECU will use to determine the proper fueling for the car. I would give it a few more weeks, if not months, and let the guys get the entire ECU decoded. Otherwise you will just find yourself constantly re-working stuff with each release anyway.
whoa! this is confused me! This Flash is same thing that DynoFlash or shive Flash or in mail Flash or Tune Flash Tuner shop?
I should go to Sent Someone to Flash my ECU or i can do that Download that stuff?

Not sure if Shiv is offering this functionality yet or not. Other shops can use this tool to write a flash to your ECU. Pretty sure one of the Northwest shops is using it now...but I forgot the name.
