No Response from MS
I have a DIYAutoTune built MS unit. I thinks its an MS2. I am also using a USB to serial adapter (eek).
I have the FIFO off so there is no buffer. I have tried both sets of rates (matching on each end). Com ports should be correct as well. I still wont rule out the cable but i have no access at the moment to anthing else.
Getting "no response".
When i turn the key to "on" i get a quick flash from the LEDs but none of them stay on. Should any of them remain on without the engine running? I have the wiring in the rear as per the mega manual with only the one voltage source from a switched ignition.
So...any thoughts? I have heard of having to flash the ECU with firmware (this has never been used prior nor have i had it communicated). But i can't connect to begin with.

i downloaded the DIYautotune's newest package and ill see what that yields for me. But what i still don't get is what "project" im supposed to open when i open megatune. I don't have a car1 option, only the long list of versions.

If there's no firmware on the chip, it won't communicate with megatune.
