Anyone Kill an ECU yet?


Has anyone flashed an ecu to death yet? I believe they were only spec'd for 100 flashes. I imagine they will last for many more than that, but just curious if anyone has killed one?

Anyone know of any that were "Flashed to death" yet? there has been a brief discussion on another board about instances that ended in disposal of the ECU that were claimed to be related to too many flashes.

I have killed 1 ecu, it was my first bench ecu used for testing, as you can imagine it has been flashed ALOT a real lot like over 500 times so i was not too surprised. I have also flashed the ecu in my road bike ALOt and it is perfectly fine.

I think the power interrupt is pretty standard for solid state items. I've cooked a USB flash drive just from a hot swap before.

I wonder if there is a way to integrate some capacitance into the circuit to allow a fost shutdown if the main power is interrupted. Basically, close the flash cycle with teh last little bit of energy rather than cut it off cold. There is a circuit listed on the AEM forums to do this for the AQ-1 logger so it can just be shut down rather than the logging stopped first everytime.


Justin,
What did the one on your bench do? Failure to connect or write errors? Just wondering what the result was when it died.

My bench flashing ecu would fail at unlocking the MCU with the password, this is a common issue when power is pulled as well. I have a friend in Euope who i have sent it to who will be using a m32r JTAG interface connected directly to the MCU pins to see if he can pull the bin file from it to work out what is going on with it and if it can be repaired. I have tried all sorts of things. It would be great to work out a way to bring them back from the dead!

I had an exhaust leak melt PC cables together, took out the injector drivers for #2 cylinder. All else ok but cease to fire injector. Was good and bad for me, had to replace ecu, entire wiring harness and ditch PC and found software editor here. Best thing that could have happened, albeit the long way to get there.

My dyno tuner told me that these ecu's are good for up to 1000 flashes. Ive flashed mine on my 08 around 250 times maybe more and all is well with it.
