2G EcuFlash Can't Read/Write or even detect ECU.

[Heavyslowfwd]

So I've had my OP 2.0 cable for a while, and finally got all my exhaust leaks tracked down to start tuning. I plugged in both the mitsu reflash connector as well as the 2.0 into their respective slots and plugged the usb into my laptop and the drivers attempted to download but failed. I then installed the drivers from the usb drivers folder and my laptop said the cable was functioning correctly.

When I opened up ecuflash, it ran through a long code that seemed to repeat the same 5 lines over and over. It looks similar to the OP's log in this thread: http://www.dsmtuners.com/threads/cant-read-write-in-ecuflash-evo-8-ecu-swap.451588/ except it loads the API, the DLL, version, then my device serial number and says interface close. It does these same lines ~6 times until it just stops.

In the top left menu, I have no options pertaining to the ecu, just a Open Rom, Vehicle Select, and Others that I cant remember (Dont have my laptop with me right now, going on memory but it was 4 options total).

Anyway, I AM able to log in evoscan and the data transfers and appears fine, which makes me think the drivers are installed properly for the cable. So I think my problem is with the reflash connector not making a good connection or does it need a separate set of drivers?

Any insights?

what ecu do you have in the car and what year is it?

Definitely redownload and reinstall the drivers before looking elsewhere for other issues. The 2.0 cable is an unfortunately very 'touchy' and 'fragile,' however sometimes something as dumb as wiggling it around and reconnecting the cable can solve connectivity issues. Outside of that be sure you have the proper settings to read the ecu etc. I can't tell from your original post if you are trying to read or write though, and if you are having issues with reading then you may need to be sure that you have the proper rom and hex file definitions in the proper folder (you HAVE to manually place them there being that this is opensource stuff). Good luck

Here is info on compatible ecu's as you have not identified you have a H8 ecu:

Here is some helpful information that helped me with software installation. Like you, I could get Evoscan to log, but could not get ECUflash to work correctly. This may take a couple tries:
